                               Use of This Document
The information contained in this document represents the latest step in an ongoing effort of the
Environmental Protection Agency's (EPA's) National Homeland Security Research Center
(NHSRC) to provide standardized analytical methods for use by those laboratories tasked with
performing confirmatory analyses of environmental samples in support of EPA restoration efforts
following a homeland security incident.  The information also can be found on the SAM Web site
(www.epa.gov/sam), which provides searchable links to supporting information based on SAM
analytes and the analytical methods listed.

Although at this time, some of the methods listed have not been fully validated for a particular
analyte (e.g., analytes not explicitly identified in the method) or sample type, the methods are
considered to contain the most appropriate currently available techniques. Unless a published
method  listed in this document states specific applicability to the analyte/sample type for which it
has been selected, it should be assumed that method testing is needed, and adjustments may be
required to accurately account for variations in analyte/sample type characteristics, environmental
samples, analytical interferences, and data quality objectives (DQOs).

Many of the SAM analytes have only recently become an environmental concern.  EPA is actively
pursuing development and validation of Standard Analytical Protocols (SAPs) based on the
methods listed, including optimization of procedures for measuring target analytes or agents.  In
those cases where method procedures are determined to be insufficient for a particular situation,
EPA will provide guidelines regarding appropriate actions. EPA also is in the process of compiling
information  and preparing documents regarding field screening equipment, sample collection
materials, rapid screening/ preliminary identification equipment, and disposal of samples
corresponding to SAM analytes and sample types.  This will be an ongoing process as EPA will
strive to establish a consistent level of validation for all listed analytes.

                                        	Foreword

                                         Foreword
Following the events of September 11,2001, EPA's mission was expanded to account for critical needs
related to homeland security. Presidential directives identified EPA as the primary federal agency
responsible for the country's water supplies and for environmental decontamination following a chemical,
biological, and/or radiological (CBR) attack. To provide scientific and technical support to help EPA
meet this expanded role, EPA's National Homeland Security Research Center (NHSRC) was established.
The NHSRC research program is focused on conducting research and delivering products that improve
the capability of the Agency to carry out its homeland security responsibilities.

One focus area of NHSRC's research is to support the Environmental Response Laboratory Network
(ERLN), a nationwide association of federal, state, local and commercial environmental laboratories,
established by EPA. The ERLN can be deployed in response to a large-scale environmental disaster,
providing consistent analytical capability, capacity, and data quality. Toward this end, NHSRC has
worked with experts from across EPA and other federal agencies to undertake research designed to
provide appropriate, effective, and verified technologies and methods. These methods and technologies
can help the Agency determine the risks posed by CBR agents and enhance EPA's ability to detect,
contain, and clean up following an incident involving such agents.  This document provides a
compendium of methods that have been selected for use when analytical laboratories must support an
environmental restoration involving CBR contaminants.

This publication represents the sixth revision of this compendium.  This information will continue to be
revised as research progresses and new information becomes available. In addition, NHSRC will
continue to provide a searchable form of this document which is available at http://www.epa.gov/sam.
We value your comments as we move toward the development of an efficient process to manage
environmental samples and move  EPA one step closer to achieving its homeland security mission and its
overall mission of protecting human health and the environment while supporting sustainable solutions.

                              Section  1.0:  Introduction

After the terrorist attacks of September 11, 2001 and the anthrax attacks in the fall of 2001, federal and
state personnel provided response, recovery, and remediation under trying circumstances, including
unprecedented demand on their capabilities to analyze environmental samples. In reviewing these events,
the Environmental Protection Agency (EPA) identified several areas where the country could better
prepare itself in the event of future terrorist incidents.  The need to improve the nation's laboratory
capacity and capability to analyze environmental samples following a homeland security event (i.e.,
chemical, biological, and/or radiological [CBR] crime/attack) was one of the most important areas
identified.

In response, EPA formed the Homeland Security Laboratory Capacity Work Group to identify and
implement opportunities for near-term improvements and to develop recommendations for addressing
longer-term laboratory issues.  The EPA Homeland Security Laboratory Capacity Work Group consists of
representatives from the Office of Research and Development (ORD), Office of Air and Radiation
(OAR), Office of Water (OW), Office of Solid Waste and Emergency Response (OSWER), Office of
Environmental Information, Office of Chemical Safety and Pollution Prevention, and several EPA
regional offices.

A critical area identified by the work group was the need for a list of analytical methods to be used by all
laboratories when analyzing homeland security event samples and, in particular, when analysis of many
samples is required over a short period of time. Having standardized methods would reduce confusion,
permit sharing of sample load between laboratories, improve data comparability, and simplify the task of
outsourcing analytical support to the commercial laboratory sector.  Standardized methods would also
improve the follow-up activities of validating results, evaluating data, and making decisions.  To this end,
work group members formed an Analytical Methods Subteam to address homeland security methods
issues.

The Analytical Methods Subteam recognized that widely different analytical methods are required for
various phases of environmental sample analyses in support of homeland security preparation and
response: (1) ongoing surveillance and monitoring; (2) response and rapid screening for determining
whether an event has occurred; (3) preliminary site characterizations to determine the extent and type of
contamination; and (4) confirmatory laboratory analyses to plan, implement, and evaluate the
effectiveness of site remediation. Figure 1-1 represents these analytical phases.  EPA's Standardized
Analytical Methods for Environmental Restoration Following Homeland Security Events (SAM) provides
information for analytical methods to be applied during the "Site  Remediation" phase.

                              Section 2.0:  Background

In support of this document, EPA periodically assembles methods experts from within EPA and other
federal agencies to review methods and, if necessary, revise the methods listed. SAM identifies a single
method or method group per analyte/sample type to ensure a consistent analytical approach across
multiple laboratories when analyzing environmental samples following an event.  Method selection is
based on consideration of specific criteria that emphasize method performance and include existing
laboratory capabilities, laboratory capacity, method applicability to multiple environmental sample types,
and method applicability to multiple SAM analytes. For some analytes, the preferred method is a clear
choice; for others, competing criteria make the choice more difficult. Final method selections are based
on technical recommendations from the SAM work groups. For analytes where limited laboratory
testing/experience exists, such as chemical warfare agents, methods were selected based on their
applicability to similar chemicals (e.g., nerve agents and some pesticides).  In these cases, laboratory
studies to test the ability of the selected method to measure the target analyte(s) are either underway or
planned.  Figure 2-1 summarizes steps and provides the criteria used during the SAM method selection
process. It is important to note that the method selection criteria included in this figure are listed in non-
hierarchical order and, in some cases, only a subset of the  criteria was considered.

Since 2004, EPA's National Homeland Security Research Center (NHSRC) has brought together experts
from across EPA and its sister agencies to develop this compendium of analytical methods to be used
when analyzing environmental samples, and to address site characterization, remediation and clearance
following future homeland security events. Participants have included representatives from EPA program
offices, EPA regions, EPA laboratories, Centers for Disease Control and Prevention (CDC), Food and
Drug Administration (FDA), Department of Homeland Security (DHS), Federal Bureau of Investigation
(FBI), Department of Defense  (DoD), Department of Agriculture (USDA), and U.S. Geological Survey
(USGS).  Methodologies were considered for chemical and biological agents of concern in the types of
environmental samples that would be anticipated. The primary objective of this effort was to identify
appropriate SAM Analytical Methods Subteam consensus methods that represent a balance between
providing existing, documented, determinative techniques and providing consistent and valid analytical
results.

A survey of available confirmatory analytical methods for approximately 120 biological and chemical
analytes was conducted using existing resources including the following:
•     National Environmental  Methods Index (NEMI) and NEMI for Chemical, Biological, and
      Radiological Methods (NEMI-CBR)
•     Environmental Monitoring Method Index (EMMI)
•     EPA Test Methods Index
      EPA Office of Solid Waste SW-846 Methods
•     EPA Microbiological Methods
•     National Institute for Occupational Safety and Health (NIOSH) Manual of Analytical Methods
      (NMAM)
•     Occupational Safety and Health Administration (OSHA) Index of Sampling and Analytical
      Methods
•     AOAC International
•     ASTM International
•     International Organization for Standardization (ISO) methods
•     Standard Methods for the Examination of Water and Wastewater
•     PubMED Literature Database

In September 2004, EPA published Standardized Analytical Methods for Use During Homeland Security
Events, Revision 1.0 (SAM, Revision 1.0, EPA/600/R-04/126), which provided a list of analytical and
sample preparation methods that were selected for measurement of 82 chemical analytes in
SAM 2010 (Revision 6.0)                           3                                   October 2010

                                                                           Section 2 - Background
aqueous/liquid, solid, oily solid, and air samples, and 27 biological analytes in water, dust, and aerosol
samples. During 2005, SAM was expanded to include radionuclides, several persistent chemical warfare
agent degradation products, a drinking water sample type, methods for determination of the viability of
biological organisms, and a separate section for biotoxin analytes. Where necessary, the methods
included in SAM Revision 1.0 were updated to reflect more recent or appropriate methodologies.  Similar
efforts to those used for method selection during development of SAM Revision 1.0 were undertaken to
select and include methods for measurement of radionuclides and chemical warfare agent degradation
products in all sample types, for measurement of CBR analytes in drinking water, and to determine the
viability of biological organisms.  These additional analytes and the corresponding methods selected were
included in SAM Revision 2.0.

During 2006, SAM was revised further to incorporate analytes included on updated federal agency lists,
provide additional or more current method listings for target analytes, incorporate explosives into the
chemical analytes listing, combine identification and viability methods information for pathogens, and
address comments from EPA Science Advisory Board's Homeland Security Advisory Committee1 to
clarify the intended use of the document. These changes were included in SAM Revision 3.0
(Standardized Analytical Methods for Environmental Restoration Following Homeland Security Events,
February 2007 / EPA/600/R-07/015). SAM Revision 3.0 included a new title to emphasize the intended
use of SAM methods for analysis during environmental restoration activities.  Following publication of
SAM Revision 3.0, SAM work groups updated the document to include the addition of several chemical
analytes, one radionuclide, and one biotoxin, along with corresponding selected methods, and provided
the updated documents as SAM Revision 3.1 (November 2007 / EPA/600/R-07/136). In 2007, NHSRC
also developed a Web-based version of the SAM document to allow users and other stakeholders to
search for specific needs and to submit questions and comments regarding the information.

Since publication of SAM Revision 3.1 and its corresponding Web site, NHSRC has continued to
convene technical work groups to evaluate and, if necessary, update the analytes and methods that are
listed.  During development of SAM Revision 4.0 (September 2008), work groups added a wipe sample
type for chemical analytes and several polymerase chain reaction (PCR) methods for pathogens. A
drinking water sample type was added during development of SAM Revision 5.0 (September 2009).
SAM Revisions 4.0 and 5.0 also reflect the addition of several chemical, radiochemical, and biotoxin
analytes. The current SAM Revision 6.0 (September 2010) reflects the addition of several more
chemical, radiochemical, and biotoxin analytes along with removal of the non-aqueous/organic solid
sample types in the chemistry methods section. SAM Revision 6.0 also reflects temporary removal of
sections pertaining to pathogens methods for reformatting and further consideration. In the next revision
of SAM, NHSRC and its partners  plan to revise the document's title to better reflect its focus.

In addition to updating SAM analytes and methods, SAM work groups have identified four areas for
development of SAM companion documents to provide information regarding field screening equipment,
sample collection, rapid screening and preliminary analysis equipment, and sample disposal to
supplement the analytical methods included in SAM. The information listed in these documents
corresponds to the analytes and methods in SAM and will be updated periodically to reflect revisions to
SAM.  Currently available SAM companion documents are listed in Attachment 1.

                        Section  3.0:  Scope and Application

The premise and purpose of this document is to standardize the analytical methods that will be used in
cases when multiple laboratories are called on to analyze environmental samples following a homeland
security event (i.e., CBR crime/attack). The document also is intended as a tool that will be available to
assist state and local laboratories in planning for and analyzing environmental samples following a
homeland security event.  The methods presented in this document should be used to:
•    Determine the extent of site contamination (assumes early responders have identified contaminants
     prior to EPA's remediation effort), and

     Confirm effectiveness of decontamination in support of site clearance decisions.

The methods provided are limited to those that would be used to determine, to the extent possible within
analytical limitations, the presence of chemical, radiochemical, pathogen, and biotoxin analytes of
concern and their concentrations and viability, when applicable, in environmental media. The methods
include detailed laboratory procedures for confirming the identification of analytes and determining their
concentrations in environmental samples. The methods, therefore, are not designed to be used for rapid
or immediate response or for conducting an initial evaluation (triage or screening) of suspected material
to determine if it poses an immediate danger or should be analyzed in specially designed, highly secure
facilities. This document also is not intended to provide information regarding sample collection
activities or equipment. Methods for addressing these needs are and will be the subject of other efforts.
In conjunction with SAM, NHSRC is developing SAM companion documents that are intended to
provide information regarding field screening equipment, sample collection, laboratory rapid
screening/preliminary identification equipment, and sample disposal in support of the confirmatory
methods and analytes listed in SAM. Currently available SAM companion documents are listed in
Attachment 1.

Methods are provided in this document as corresponding to specific analyte/sample type combinations
that are listed in Appendices A (chemical), B (radiochemical), C (pathogen), and D (biotoxin).
Summaries of each method are provided in numerical order by the developing agency, throughout
Sections 5.2 (chemical methods), 6.2 (radiochemical methods), and 8.2 (biotoxin methods).
SAM 2010 (Revision 6.0)                            7                                    October 2010

                                                                    Section 3 - Scope and Application
  It is important to note that, in some cases, the methods included in this document have not been fully
  validated for the analyte/sample type combination(s) for which they have been selected. The
  information contained in this document represents the latest step in an ongoing effort by EPA's
  NHSRC to provide standardized analytical methods for use by those laboratories tasked with
  performing confirmatory analyses on environmental samples in support of EPA restoration efforts
  following a homeland security incident. The information also can be found on the SAM Web site
  (www.epa.gov/samX which provides searchable links to supporting information based on SAM
  analytes and the analytical methods listed.

  Although at this time,  some of the methods listed have not been fully validated for a particular
  analyte (e.g., analytes not explicitly identified in the method) or sample type, the methods are
  considered to contain the most appropriate currently available techniques. Unless a published
  method listed in this document  states specific applicability to the analyte/sample type combination
  for which it has been selected, it should be assumed that method testing is needed, and adjustments
  may be required to accurately account for variations in analyte characteristics, environmental
  samples,  analytical interferences, and target risk levels.

  Many of the SAM analytes have only recently become an environmental concern. EPA is actively
  pursuing  development and validation of Standard Analytical Protocols (SAPs) based on the methods
  listed, including optimization of procedures for measuring target analytes or agents.  In those cases
  where method procedures are determined to be insufficient for a particular situation, EPA will
  provide guidelines regarding appropriate actions. This will be an ongoing process as EPA will strive
  to  establish a consistent level of validation for all listed analvtes.
EPA recognizes that specification of a single method may limit laboratory capacity and techniques that
may be needed to evaluate difficult samples. In those cases where method procedures are determined to
be insufficient for a particular situation, EPA will provide guidelines regarding appropriate actions (see
list of contacts in Section 4). Where further development and testing are necessary, EPA is developing
and validating SAPs based on the methods that are listed in this document.  Once validation is complete,
data regarding the resulting method performance and data quality objectives will be available. The SAM
document and corresponding SAPs will be reviewed frequently. EPA plans to continue to update the
SAM document to address the needs of homeland security, to reflect improvements in analytical
methodology and new technologies, and to incorporate changes in analytes  based on needs. EPA also
anticipates that addenda may be generated to provide guidelines regarding issues that currently are not
addressed by this document.  Any deviations from the methods referenced in this document should be
coordinated with the appropriate point(s) of contact identified in Section 4.

Participants in the chemical, radiochemical, pathogen, and biotoxin work groups, including
representatives from the EPA, CDC, FDA, DHS, FBI, DoD, USDA, and USGS evaluated the suitability
of existing methodologies and selected this  set of methods for use by those laboratories that support EPA
environmental restoration efforts in an emergency.  EPA recognizes that this advanced selection of such
methods may pose potential risks, including the following:
      Selecting technologies that may not be the most cost-effective technologies currently available for
      addressing the particular situation at hand;

      Selecting methodologies that may not be appropriate for use in responding to a particular
      emergency because EPA did not anticipate having to analyze for a particular analyte or
      analyte/sample type combination; and
•    Preventing development and adoption of new and better measurement technologies.

To address these potential risks as soon as possible, EPA plans to take several steps. These include the
following:

•     Developing and specifying measurement quality objectives for all analyte/sample type
      combinations listed in this document. This includes required minimum standards of accuracy (bias
      and precision) and sensitivity for the analysis of samples that support the data quality needs of the
      particular stage of the emergency response/recovery process);
      Specifying guidelines for ensuring the analytical methods listed provide results that are consistent
      with and support their intended use as indicated in SAM;
•     Working with other government agencies and the private sector to establish a laboratory network to
      ensure that laboratories, selected to assist EPA and its federal, state, and local partners in
      responding to homeland  security events, have the requisite expertise and systems to perform this
      type of testing; and

•     Continuing to work with multiple agencies and stakeholders to update SAM and supporting
      documents periodically.

Public officials must accurately assess all of the activities that are needed concerning site contamination
following an emergency situation.  These activities include initial assessment of potential site
contamination for determination of immediate public and environmental risk, determination of the extent
of contamination, and full remediation of the site.  EPA recognizes that having data of known and
documented quality is critical in making proper decisions during each of these activities. Data quality
objectives (DQOs) must be established for each response activity2. These DQOs are based upon needs
for both quality and response time. During initial assessments, time is of utmost importance and DQOs
must be established that weigh the need for rapid analytical response (e.g., using screening methods)
against the need for very high quality data (confirmational methods such as those listed in SAM). Many
of the methods listed in this document include quality control (QC) requirements for collecting and
analyzing samples.  EPA will assess these QC requirements to ensure analytical data quality supports
decisions concerning site remediation and release. These QC requirements may be adjusted as necessary
to maximize data and decision  quality.  Specific QC considerations and recommendations for analysis of
samples for chemical, radiochemical, pathogen, and biotoxin analytes are provided in each corresponding
section of this  document (i.e., Sections 5.1.2, 6.1.2, 7.1.2, and 8.1.2, respectively).

                    Section 5.0:  Selected Chemical  Methods

Appendix A provides a list of methods to be used in analyzing environmental samples for chemical
contaminants during remediation activities that result from a homeland security event. Methods are listed
for each analyte and for each sample type that potentially may need to  be measured and analyzed when
responding to an environmental emergency. Procedures from peer-reviewed journal articles are listed for
those analyte-sample type combinations where methods are not available. Once standard procedures are
available, the literature references will be replaced.
 Please note: This section provides guidance for selecting chemical methods that have a high likelihood
 of assuring analytical consistency when laboratories are faced with a large scale environmental
 restoration crisis. Not all methods have been verified for the analyte/sample type combination listed in
 Appendix A. Please refer to the specified method to identify analyte/sample type combinations that
 have been verified.  Any questions regarding information discussed in this section should be addressed
 to the appropriate contact(s) listed in Section 4.
Appendix A is sorted alphabetically by analyte and includes the following information:
•   Analyte(s). The component, contaminant, or constituent of interest.
•   Chemical Abstracts Service Registration Number (CAS RN). A unique identifier for chemical
    substances that provides an unambiguous way to identify a chemical or molecular structure when
    there are many possible systematic, generic, or trivial names.
    Determinative technique. An analytical instrument or technique used to determine the quantity and
    identification of compounds or components in a sample.
    Method type. Two method types (sample preparation and determinative) are used to complete
    sample analysis. In some cases, a single method contains information for both sample preparation
    and determinative procedures.  In most instances, however, two separate methods may need to be
    used in conjunction.
    Solid samples. The recommended method/procedure to identify and measure the analyte of interest
    in solid phase  samples.
•   Aqueous liquid samples.  The recommended method/procedure to identify and measure the analyte
    of interest in aqueous liquid phase samples.
•   Drinking water samples.  The recommended method/procedure to identify and measure the analyte
    of interest in drinking water samples.
•   Air samples.  The recommended method/procedure to identify and measure the analyte of interest in
    air samples.
    Wipe samples. The recommended method/procedure to identify and measure the analyte  of interest
    in wipes used to collect a sample from a surface.

Following a homeland security event, it is assumed that only those areas with contamination greater than
pre-existing/naturally prevalent levels commonly found in the environment would be subject to
remediation. Dependent on site- and event-specific goals, investigation of background levels using
methods listed in Appendix A is recommended.

5.1.1  Standard Operating Procedures for Identifying Chemical Methods
To determine the appropriate method to be used on an environmental sample, locate the analyte of
concern under the "Analyte(s)" column in Appendix A: Chemical Methods. After locating the analyte of
concern, continue across the table to identify the appropriate determinative technique (e.g., high
performance liquid chromatography [HPLC], gas chromatography - mass spectrometry [GC-MS]), then
identify the appropriate sample preparation and determinative method(s) for the sample type of interest
(solid, aqueous liquid, drinking water, air, or wipe). In some cases, two methods (sample preparation and
determinative)  are needed to complete sample analysis.

Sections 5.2.1 through 5.2.85 below provide summaries of the sample preparation and determinative
methods listed  in Appendix A. Once a method has been identified in Appendix A, Table 5-1 can be used
to locate the method summary.

5.1.2   General QC Guidelines for Chemical Methods
Having analytical data of appropriate quality requires that laboratories: (1) conduct the necessary QC
activities to ensure that measurement systems are in control and operating correctly; (2) properly
document results of the analyses; and (3) properly document measurement system evaluation of the
analysis-specific QC, including corrective actions.  In addition to the laboratories being capable of
generating accurate and precise data during site remediation, they must be able to deliver results in a
timely and efficient manner.  Therefore, laboratories must be prepared with calibrated instruments, the
proper standards, standard analytical procedures, standard operating procedures, and qualified and trained
staff.  Moreover, laboratories also must be capable of providing rapid turnaround of sample analyses and
data reporting.

The level or amount of QC needed during sample analysis and reporting depends on the intended purpose
of the data that are generated (e.g., the decision(s) to be made).  The specific needs for data generation
should be identified.  QC requirements and data quality objectives should be derived based on those

                                                               Section 5 - Selected Chemical Methods
needs, and should be applied consistently across laboratories when multiple laboratories are used. For
almost all of the chemical warfare agents, most laboratories will not have access to analytical standards
for calibration and QC. Use of these agents is strictly controlled by the DoD and access is limited. For
information  regarding laboratory analysis of samples containing CWAs or laboratory requirements to
possess and  use ultra-dilute agent standards, please contact Terry Smith, EPA's Office of Emergency
Management, at (202) 564-2908.

A minimum set of analytical  QC procedures  should be planned, documented, and conducted for all
chemical testing.  Some method-specific QC requirements are described in many of the individual
methods that are cited in this document and will be referenced in any SAPs developed to address specific
analytes and sample types of concern. Individual methods, sampling and analysis protocols, or
contractual statements of work should also be consulted to determine if any additional QC might be
needed.  Analytical QC requirements generally consist of analysis of laboratory control samples to
document whether the analytical system is in control; matrix spikes to identify and quantify measurement
system accuracy for the media of concern and, at the levels of concern, various blanks as a measure of
freedom from contamination; as well as matrix spike duplicates or sample replicates to assess data
precision.

In general, for measurement of chemical analytes, appropriate QC includes an initial demonstration of
measurement system capability, as well as ongoing analysis of standards and other samples to ensure the
continued reliability of the analytical results. Examples of appropriate QC include:
    Demonstration that the measurement system is operating properly:
    >•  Initial calibration; and
    >•  Method blanks.
    Demonstration of analytical method suitability for intended use:
    >•  Detection and quantitation limits;
    >•  Precision  and recovery (verify measurement system has adequate accuracy); and
    >•  Analyte/matrix/level of concern-specific QC samples (verify that measurement system has
       adequate sensitivity at levels of concern).
    Demonstration of continued analytical method reliability:
    >•  Matrix spike/matrix spike duplicates (MS/MSDs) (recovery and precision);
    >•  QC  samples (system accuracy and sensitivity at levels of concern);
    >•  Surrogate spikes (where appropriate);
    >•  Continuing calibration verification; and
    >•  Method blanks.

QC tests should be consistent with EPA's Good Laboratory Practice Standards
(http://www.epa.gov/oecaerth/monitoring/programs/fifra/glp.html) and be run as  frequently as necessary
to ensure the reliability of analytical results.  Additional guidance can be found at:
www.epa.gov/quality/qatools.html; in Chapter 1 of EPA SW-846 Hazardous Test Methods
(http://www.epa.gov/epawaste/hazard/testmethods/sw846/pdfs/chapl.pdf); and in EPA's Drinking Water
Laboratory Certification Manual
(http://www.epa.gov/ogwdwOOO/methods/pdfs/manual_labcertification.pdf). As with the identification of
needed QC samples, the frequency of QC sampling should be established based on an evaluation of data
quality objectives. The type and frequency of QC tests can be refined over time.

Ensuring data quality also requires that laboratory results are properly assessed and documented.  The
results of the data quality assessment are transmitted to decision makers.  This evaluation is as important
as the data for ensuring informed and effective decisions. While some degree of data evaluation is
necessary in order to be able to confirm data quality, 100% verification and/or validation is neither
necessary nor conducive to efficient decision making in emergency situations.  The level of such reviews
should be determined based on the specific situation being assessed and on the corresponding data quality

SAM2010 (Revision 6.0)                           32                                   October 2010

objectives.  In every case, the levels of QC and data review necessary to support decision making should
be determined as much in advance of data collection as possible.

Please note: The appropriate point of contact identified in Section 4 should be consulted regarding
appropriate quality assurance (QA) and QC procedures prior to sample analysis. These contacts will
consult with the EPA Environmental Response Laboratory Network (ERLN) coordinator responsible for
laboratory activities during the specific event to ensure QA/QC procedures are performed consistently
across laboratories. EPA program offices will be responsible for ensuring that the QA/QC practices are
implemented.
5.1.3  Safety and Waste Management
It is imperative that safety precautions are used during collection, processing, and analysis of
environmental samples. Laboratories should have a documented health and safety plan for handling
samples that may contain the target CBR contaminants. Laboratory staff should be trained in, and need to
implement, the safety procedures included in the plan. In addition, many of the methods summarized or
cited in Section 5.2 contain some specific requirements, guidelines, or information regarding safety
precautions that should be followed when handling or processing environmental samples and reagents.

These methods also provide information regarding waste management.  Other resources that can be
consulted for additional information include the following:

    Etiologic Agents.

Method Developed for:  Determination of metals in solution. This method is a consolidation of existing
methods for water, wastewater, and solid wastes.
Method Selected for:  SAM lists this method for preparation and analysis of aqueous liquid and drinking
water samples.
Detection and Quantitation: Method detection limits (MDLs) in aqueous samples have been found to
be 0.008 mg/L for arsenic, 0.003 mg/L for vanadium, and 0.001 mg/L for thallium.

Description of Method:  This method will determine metal-containing compounds only as the total metal
(e.g., total arsenic) in aqueous samples. An aliquot of a well-mixed, homogeneous sample is accurately
weighed or measured for sample processing. For total recoverable analysis of a sample containing
undissolved material, analytes are first solubilized by gentle refluxing with nitric and hydrochloric acids.
After cooling, the sample is made up to volume, mixed, and centrifuged or allowed to settle overnight
prior to analysis.  For determination of dissolved analytes in a filtered aqueous sample aliquot, or for the
"direct analysis" total recoverable determination of analytes in drinking water where sample turbidity is <
1 nephelometric turbidity units (NTU), the sample is made ready for analysis by the addition of nitric
acid, and then diluted to a predetermined volume and mixed before analysis. The prepared sample is
analyzed using ICP-AES.  Specific analytes targeted by Method 200.7 are listed in Section 1.1 of the
method.

Special Considerations: Laboratory testing is currently underway for speciation of lewisite  1 using GC-
MS techniques. Users should consult with the appropriate point of contact listed in Section 4.0 regarding
use of graphite furnace atomic absorption spectrophotometry (GFAA) as a back-up or for additional
confirmatory analyses.

detect total mercury (inorganic and organic mercury), the sample  is treated with potassium permanganate
and potassium persulfate to oxidize organic mercury compounds prior to analysis. Inorganic mercury is
reduced to the elemental state (using stannous chloride) and aerated from solution. The mercury vapor
passes through a cell positioned in the light path of a CVAA spectrophotometer. The concentration of
mercury is measured using the CVAA spectrophotometer.

Method Selected for: SAM lists this method for preparation and analysis of aqueous liquid and drinking
water samples for fluoride, fluoroacetic acid, fluoroacetate salts, and methyl fluoroacetate. It also should
be used for analysis of solid, air, and/or wipe samples for fluoroacetic acid, fluoroacetate salts, methyl
fluoroacetate, and sodium azide when appropriate sample preparation techniques have been applied.
Detection and Quantitation: The detection limit for fluoride in reagent water is 0.009 mg/L. The MDL
varies depending upon the nature of the sample and the specific instrumentation employed.  The estimated
calibration range should not extend over more than 2 orders of magnitude in concentration over the
expected concentration range of the samples.

Description of Method: This method was developed for analysis of aqueous samples, and can be
adapted for analysis of prepared solid and air samples when appropriate sample preparation techniques
have been applied (see Appendix A). A small volume of an aqueous liquid sample (10 (iL or 50 (iL) is
introduced into an ion chromatograph.  The volume selected depends on the concentration of
fluoroacetate ion in the sample.  The anions of interest are separated and measured, using a system
comprising a guard column, analytical  column, suppressor device, and conductivity detector. The
separator columns and guard columns,  as well as eluent conditions, are identical. To achieve comparable
detection limits, an ion chromatographic system must use suppressed conductivity detection, be properly
maintained, and be capable of yielding a baseline with no more than 5  nS noise/drift per minute of
monitored response over the background conductivity.

Special Considerations: For sodium azide, if analyses  are problematic, refer to column manufacturer
for alternate  conditions.

Method Selected for: SAM lists this method for preparation and analysis of drinking water samples.
Detection and Quantitation: The applicable range is 5 to 500 (ig/L.

Description of Method: Cyanide is released from cyanide complexes as hydrocyanic acid by manual
reflux-distillation, and absorbed in a scrubber containing sodium hydroxide solution. The cyanide ion in
the absorbing solution is converted to cyanogen chloride by reaction with chloramine-T, which
subsequently reacts with pyridine and barbituric acid to give a red-colored complex.

Special Considerations: Some interferences include aldehydes, nitrate-nitrite, and oxidizing agents,
such as chlorine, thiocyanate, thiosulfate, and sulfide. These interferences can be  eliminated or reduced
by distillation.

Method Selected for:  SAM lists this method for preparation and analysis of drinking water samples.
Detection and Quantitation: The working range for ammonia is 0.01 to 2.0 mg/L.

Description of Method: This method identifies and determines the concentration of ammonia in
drinking water samples by spectrophotometry.  Samples are buffered at a pH of 9.5 with borate buffer to
decrease hydrolysis of cyanates and organic nitrogen compounds, and are distilled into a solution of boric
acid. Alkaline phenol and hypochlorite react with ammonia to form indophenol blue that is proportional
to the ammonia concentration. The blue color formed is intensified with sodium nitroprusside and
measured spectrophotometrically.

Special Considerations:  Reduced volume distillation techniques, such as midi-distillation or micro-
distillation, can be used in  place of traditional macro-distillation techniques.

Description of Method: VOCs and surrogates with low water solubility are extracted (purged) from the
sample matrix by bubbling an inert gas through the aqueous sample. Purged sample components are
trapped in a tube containing suitable sorbent materials. When purging is complete, the sorbent tube is
heated and backflushed with helium to desorb the trapped sample components into a capillary gas
chromatography (GC) column interfaced to a mass spectrometer (MS).  The column is temperature
programmed to facilitate the separation of the method analytes, which are then detected with the MS.
Specific analytes targeted by Method 524.2 are listed in Section 1.1 of the method.

Special Considerations:  The most recent version of this method (Method 524.3) requires
instrumentation, such as cryogenic auto samplers, which are not currently in common use. If laboratory
use of this equipment increases, Method 524.3 may be considered for SAM applications.

methylamine, which is in turn reacted to form a fluorescent isoindole that is detected by a fluorescence
(FL) detector.  Analytes also are quantitated using the external standard technique.

Method Selected for:  SAM lists this method for preparation and analysis of aqueous liquid and drinking
water samples.
Detection and Quantitation:  The estimated detection limit (EDL) using MTBE and ammonium
chloride-preserved reagent water on a 100% dimethylpolysiloxane (DB-1) column has been found to be
0.014 ug/L.

Description of Method: This is a GC-ECD method applicable to the determination of halogenated
analytes in finished drinking water, drinking water during intermediate stages of treatment, and raw
source water.  A 50-mL sample aliquot is extracted with 3 mL of methyl fert-butyl ether (MTBE) or 5 mL
of pentane.  Two uL of the extract is then injected into a GC equipped with a fused silica capillary
column and linearized ECD for separation and analysis. This liquid/liquid extraction technique efficiently
extracts a wide boiling range of non-polar and polar organic components of the sample.  Thus,
confirmation is quite important, particularly at lower analyte concentrations. A confirmatory column is
suggested for this purpose.

Special Considerations:  The presence of chloropicrin should be confirmed by either a secondary GC
column or by an MS.

Detection and Quantitation: MDLs for formaldehyde in reagent water were calculated as 0.09 and 0.08
(ig/L for primary and secondary columns, respectively. The applicable concentration range is
approximately 5 to 40 (ig/L.

Description of Method:  A 20-mL volume of water sample is adjusted to pH 4 with potassium hydrogen
phthalate (KHP) and the analytes are derivatized at 35°C for 2 hours with  15 mg of O-
(2,3,4,5,6-pentafluorobenzyl)-hydroxylamine (PFBHA) reagent. The oxime derivatives are extracted
from the water with 4 mL of hexane. The extract is processed through an acidic wash step, and analyzed
by FGC-ECD. The target analytes are identified and quantified by comparison to a procedural standard.
Two chromatographic peaks will be observed for many of the target analytes. Both (E) and (Z) isomers
are formed for carbonyl compounds that are asymmetrical, and that are not sterically hindered.  The (E)
and (Z) isomers may not be chromatographically resolved in a few cases.  Compounds with two carbonyl
groups, such as glyoxal and methyl glyoxal, can produce even more isomers. Chromatographic peaks
used for analyte identification are provided in Section 17, Table 1 and Figure 1 of the method.

Special Considerations: All results should be confirmed on a second, dissimilar capillary GC column.

Determinative Method: EPA SW-846 Method 8015C, Method 8270D, or Method 8321B. Refer to
Appendix A for which of these determinative methods should be used for a particular analyte.

Method Developed for: Organic compounds in aqueous samples
Method Selected for:  SAM lists this method for preparation of aqueous liquid and/or drinking water
samples. Please note: Drinking water samples for fenamiphos should be prepared and analyzed by EPA
Method 525.2; drinking water samples for thiofanox should be prepared and analyzed by EPA Method
531.2; aqueous/liquid samples for bromadiolone should be analyzed using ASTM D7600-09; aqueous
liquid samples for EDEA, MDEA, and TEA should be analyzed using ASTM D7599-09. All other
drinking water and aqueous liquid samples should be prepared using this method (SW-846 Method
3520C).

Description of Method: This method is applicable to the isolation and concentration of water-insoluble
and slightly soluble organics in preparation for a variety of chromatographic procedures. A measured
volume of sample, usually 1 L, is placed into a continuous liquid-liquid extractor, adjusted, if necessary,
to a specific pH and extracted with organic solvent for 18 to 24 hours. The extract is filtered through
sodium sulfate to remove residual moisture, concentrated, and exchanged as necessary into a solvent
compatible with the cleanup or determinative procedure used for analysis.

Special Considerations:  Some of the target compounds will hydrolyze in water, with hydrolysis rates
dependant on various factors such as sample pH and temperature.  For more information on the
preparation and analysis of thiofanox, see application note:

analyte.

Method Developed for:  Organic compounds in ground water, wastewater, and Toxicity Characteristic
Leaching Procedure (TCLP, Method 1311) leachates
Method Selected for: SAM lists this method for preparation of aqueous liquid and/or drinking water
samples. Please note: Drinking water samples for dichlorvos, fenamiphos, and mevinphos should be
prepared and analyzed by EPA Method 525.2; drinking water samples for thiofanox should be prepared
and analyzed by EPA Method 531.2; aqueous liquid samples for EMPA, IMPA, MPA, and PMPA should
be prepared and analyzed using ASTM D7597-09; aqueous liquid samples for EDEA, MDEA and TEA
should be prepared and analyzed using ASTM D7599-09; aqueous liquid samples for bromadiolone
should be prepared and analyzed using ASTM 7600-09; aqueous liquid samples for thiodiglycol should
be prepared and analyzed using ASTM 7598-09. All other drinking water samples and all aqueous liquid
samples should be prepared using this method (SW-846 Method 3535A).

Description of Method:  This method describes a procedure for isolating target organic analytes from
aqueous and liquid samples using SPE media.  Sample preparation procedures vary by analyte group.
Following any necessary pH adjustment, a measured volume of sample is extracted by passing it through
the SPE medium (disks or cartridges), which is held in an extraction device designed for vacuum filtration
of the sample. Target analytes are eluted from the solid-phase media using an appropriate solvent which
is collected in a receiving vessel. The resulting solvent extract is dried using sodium sulfate and
concentrated, as needed.

Special Considerations: Refer to footnote provided in analyte table above for special considerations
that should be applied when measuring specific analytes. Tetramethylenedisulfotetramine may require
SPE extraction using acetone or methyl ethylketone. Water samples that contain a high level of
particulates or a large amount of humic products may not be extractable by SPE. Some of the target
compounds will hydrolyze in water, with hydrolysis rates dependant on various factors such as sample pH
and temperature.

Description of Method: Approximately 10 g of solid sample is mixed with an equal amount of
anhydrous sodium sulfate and placed in an extraction thimble or between two plugs of glass wool. After
adding the appropriate surrogate amount, the sample is extracted using an appropriate solvent in an
automated Soxhlet extractor.  The extract is dried with sodium sulfate to remove residual moisture,
concentrated and exchanged,  as necessary, into a solvent compatible with the cleanup or determinative
procedure for analysis.

Special Considerations: Refer to footnote provided in analyte table above for special considerations
that should be applied when measuring specific analytes.  Some of the target compounds will hydrolyze
in water, with hydrolysis rates dependant on various factors such as sample pH and temperature.

Appendix A for which of these determinative methods should be used for a particular analyte.

Method Developed for: Organic compounds in soils, clays, sediments, sludges, and waste solids
Method Selected for:  SAM lists this method for preparation of solid samples.
Detection and Quantitation: This method has been validated for solid matrices containing 250 to
12,500 ug/kg of semivolatile organic compounds, 250 to 2500 ug/kg of organophosphorus pesticides, 5 to
250 ug/kg of organochlorine pesticides, 50 to 5000 ug/kg of chlorinated herbicides, and 1 to 2500 ng/kg
of poly chlorinated dibenzo-p-dioxins (PCDDs) / poly chlorinated dibenzofurans (PCDFs).

Description of Method: Approximately 10 to 30 g of soil sample is prepared for extraction either by air
drying the sample, or by mixing the sample with anhydrous sodium sulfate or pelletized diatomaceous
earth. The sample is then ground and loaded into the extraction cell.  The extraction cell containing the
sample is heated to the extraction temperature, pressurized with the appropriate solvent system, and
extracted for 5 minutes (or as recommended by the instrument manufacturer). The extract may be
concentrated, if necessary,  and exchanged into a solvent compatible with the cleanup or determinative
step being employed.

Special Considerations:  Refer to footnote provided in analyte table above for special considerations
that should be applied when measuring specific analytes. Sodium sulfate can cause clogging, and air-
drying or pelletized diatomaceous earth may be preferred.  Phencyclidine and VX require extraction with

analyte.

Method Developed for:  Extracting volatile, semivolatile, and nonvolatile organic compounds from
solids such as soils, sludges, and wastes
Method Selected for: SAM lists this method for preparation of wipe samples.

Description of Method:  Samples are prepared by shake extraction with an organic solvent in sealed
extraction tubes. Careful manipulation of the sample, solvent, drying agent, and spiking solutions during
the procedure minimizes loss of volatile compounds while maximizing extraction of volatile,
semivolatile, and nonvolatile compounds. Sample extracts are collected, dried, and concentrated using a
modification of the Kuderna-Danish concentration method or other appropriate concentration technique.
By increasing the number of theoretical plates and reducing the distillation temperature, extracts are
concentrated without loss of volatile constituents. Samples should be prepared one at a time to the point
of solvent addition (i.e., do not pre-weigh a number of samples then add the solvent). Samples should be
extracted as soon after collection as possible, and exposure to air before sample extraction is minimized
as much as possible.

Special Considerations: Refer to footnote  provided in analyte table above for special considerations
that should be applied when measuring specific analytes.

Method Developed for:  HD, GB, and VX in concrete, charcoal, wood, water, brine, ash, coral, sand, and
soil
Method Selected for:  SAM lists this method for preparation of solid, aqueous liquid, and drinking water
samples.

Description of Method:  This method provides procedures for sample collection and extraction of the
referenced compounds from solids and aqueous samples.  A separate extract is required for each agent to
be measured. Glacial acetic acid is added as a preservative to samples being assayed for GB and glacial
acetic acid/sodium chloride is a preservative for samples assayed for HD. No  preservative is added for
VX. Samples are extracted with 10% isopropanol in dichloromethane by vortex mixing and filtered, if
necessary. An optional water wash is included for VX that back-extracts the compound from heavy
organics that could interfere with the assay. An optional column cleanup procedure is described to
separate GB from heavy organics, if needed. Solvents are used to elute the extract first through the
Carboprep90 column, then the silica column.

Method Developed for: VOCs in solid materials (e.g., soils, sediments, and solid waste) and oily wastes
Method Selected for:  SAM lists this method for preparation of solid samples.

Description of Method: This method describes a closed-system purge-and-trap process for analysis of
VOCs in solid samples containing low levels (0.5 to 200 ug/kg) of VOCs.  The method also provides
specific procedures for preparation of samples containing high levels (>200 ug/kg ) of VOCs. For low-
level VOCs, a 5-g sample is collected into a vial that is placed into an autosampler device.  Reagent
water, surrogates, and internal standards are added automatically, and the vial is heated to 40°C. The
volatiles are purged into an appropriate trap using an inert gas combined with sample agitation.  When
purging is complete, the trap is heated and backflushed with helium to desorb the trapped sample
components into a GC for analysis.  For high-level VOCs, samples are either collected into a vial that
contains a water-miscible organic solvent or a portion of sample is removed from the vial and dispersed in
a water-miscible solvent. An aliquot of the solvent is added to reagent water, along with surrogates and
internal standards, then purged and analyzed using an appropriate determinative method (e.g., Method
8015C or 8260C (SW-846)).

Method Developed for: Total mercury in solids, aqueous samples, and digested solutions

Detection and Quantitation: The IDL is 0.01 ng total mercury. The typical working range for this
method is 0.05 to 600 ng.

Description of Method: Controlled heating in an oxygenated decomposition furnace is used to liberate
mercury from solid and aqueous samples. The sample is dried and then thermally and chemically
decomposed within the furnace. The decomposition products are carried by flowing oxygen to the
catalytic section  of the furnace, where oxidation is completed and halogens and nitrogen/sulfur oxides are
trapped. The remaining decomposition products are then carried to an amalgamator that selectively traps
mercury. After the system is flushed with oxygen to remove any remaining gases or decomposition
products, the amalgamator is rapidly heated, releasing mercury vapor. Flowing oxygen carries the
mercury vapor through absorbance cells positioned in the light path of a single wavelength atomic
absorption spectrophotometer. Absorbance (peak height or peak area) is  measured at 253.7 nm as a
function of mercury concentration.

Special Considerations: If equipment is not available, use CVAA Methods 747 IB (EPA SW-846) for
solid samples and 7470A (EPA SW-846) for aqueous liquid samples.

Determinative Technique: GC-NPD

Method Developed for: White phosphorus in soil, sediment, and water
Method Selected for:  SAM lists this method for preparation and analysis of solid, aqueous liquid,
drinking water, and wipe samples.
Detection and Quantitation: MDLs for reagent water, well water, and pond water were calculated to be
0.008, 0.009, 0.008 (ig/L, respectively. MDLs for sand, a sandy loam soil (Lebanon soil), and soil from
the Rocky Mountain Arsenal (U.S. Army Environmental Center soil) were calculated to be 0.02, 0.43,
0.07 (ig/kg, respectively. This procedure provides sensitivity on the order of 0.01 (ig/L for water samples
and 1 (ig/kg for soil samples.

Description of Method: Method 7580 may be used to determine the concentration of white phosphorus
in soil, sediment, and water samples using solvent extraction and GC. Water samples are extracted by
one of two procedures, depending on the sensitivity required. For the more sensitive procedure, a 500-
mL water sample is extracted with 50 mL of diethyl ether.  The extract is concentrated by back extraction
with reagent water, yielding a final extract volume of approximately 1.0 mL. A 1.0 (iL aliquot of this
extract is injected into a GC equipped with a nitrogen-phosphorus detector (NPD). Wet soil or sediment
samples are analyzed by extracting a 40 g wet-weight aliquot of the sample with a mixture of 10.0 mL
degassed reagent water and 10.0 mL isooctane. The extraction is performed in a glass jar on a platform
shaker for 18 hours. A 1.0 (iL aliquot of the extract is analyzed by GC-NPD.

Special Considerations:  The presence of white phosphorus should be confirmed by either a secondary
GC column or by an MS.

Description of Method:  This method provides GC conditions for the detection of certain
nonhalogenated volatile and semivolatile organic compounds. Depending on the analytes of interest,
samples may be introduced into the GC by a variety of techniques including purge-and-trap, direct
injection of aqueous liquid samples, and solvent extraction.  An appropriate column and temperature
program are used in the GC to separate the organic compounds. Detection is achieved by a flame
ionization detector (FID). The method allows the use of packed or capillary columns for the analysis and
confirmation of the non-halogenated individual analytes.

Special Considerations:  The presence of the analytes listed in the table above should be confirmed by
either a secondary GC column or by an MS.

Sample Preparation Technique:  Purge-and-trap (solid samples, aqueous liquid, and drinking water
samples) and MSE / solvent extraction (wipe samples).

Method Developed for:  Applicable to nearly all types of samples, regardless of water content, including
various air sampling trapping media, ground and surface water, aqueous sludges, caustic liquors, acid
liquors, waste solvents, oily wastes, mousses (emulsified oil), tars, fibrous wastes, polymeric emulsions,
filter cakes, spent carbons, spent catalysts, soils, and sediments.

wipe samples.  For acrylonitrile, carbon disulfide, 1,2-dichloroethane, and methyl acrylonitrile only, EPA
Method 524.2 (rather than 8260C) should be used for analysis of drinking water samples.
Detection and Quantitation: Using standard quadrupole instrumentation and the purge-and-trap,
estimated quantitation limits are 5 ug/kg (wet weight) for soil/sediment samples and 5 ug/L for ground
water. Somewhat lower limits may be achieved using an ion trap MS or other instrumentation of
improved design. No matter which instrument is used, estimated quantitation limits (EQLs) will be
proportionately higher for sample extracts and samples that require dilution or when a reduced sample

size is used to avoid saturation of the detector. The EQL for an individual analyte is dependent on the
instrument as well as the choice of sample preparation/introduction method.

Description of Method: Volatile compounds are introduced into a GC by purge-and-trap or other
procedures (see Section 1.2 in Method 8260C). The analytes can be introduced directly to a wide-bore
capillary column or cryofocused on a capillary pre-column before being flash evaporated to a narrow-bore
capillary for analysis. Alternatively,  the effluent from the trap is sent to an injection port operating in the
split mode for injection to a narrow-bore capillary column. The column is temperature-programmed to
separate the analytes, which are then  detected with a MS interfaced to the GC. Analytes eluted from the
capillary column are  introduced into the MS via a jet separator or a direct connection.

used for a particular analyte/sample type combination.
Sample Preparation Technique:  Automated Soxhlet extraction / PFE (solid samples), CLLE / SPE
(aqueous liquid and drinking water samples), and MSE / solvent extraction / acid digestion (wipe
samples).

Method Developed for: Semivolatile organic compounds in extracts prepared from many types of solid
waste matrices, soils, air sampling media and water samples
Method Selected for: SAM lists this method for analysis of solid, aqueous liquid, drinking water, and/or
wipe samples.  Please note: drinking water samples for dichlorvos, disulfoton, disulfoton sulfoxide,
fenamiphos, and mevinphos should be prepared and analyzed by EPA Method 525.2; aqueous liquid and
drinking water samples for chloropicrin should be prepared and analyzed by EPA Method 551.1; all other
analyte/sample type combinations should be analyzed by this method (SW-846 8270D).
Detection and Quantitation:  The EDLs vary with each analyte and range between 10 and 1000 ug/L for
aqueous liquid samples and 660 and 3300 ug/kg for soil samples. The analytical range depends on the
target analyte(s) and the instrument used.

Description of Method: Samples are prepared for analysis by GC-MS using the appropriate sample
preparation and, if necessary, sample cleanup procedures. Semivolatile compounds are introduced into
the GC-MS by injecting the sample extract into a GC with a narrow-bore fused-silica capillary column.
The GC column is temperature-programmed to separate the analytes, which are then detected with a MS
connected to the GC.  Analytes eluted from the capillary column are introduced into the MS. For the
determination of BZ,  3-chloro-l,2-propanediol, dimethylphosphoramidic acid, EA2192, EMPA, IMPA,
MPA, and PMPA, a derivatization step is required prior to injection into the GC-MS.  The phosphonic
acids require derivatization with a trimethylsilyl agent and 3-chloro-l,2-propanediol requires
derivatization with a heptafluorobutyryl agent.

Special Considerations: Refer to footnotes provided in analyte table above for special considerations
that should be applied when measuring specific analytes.  Procedures for derivatization are described in

quantified fluorometrically.  The sensitivity of the method usually depends on the level of interferences
present, rather than on instrument conditions. Waste samples with a high level of extractable fluorescent
compounds are expected to yield significantly higher detection limits.

Method Developed for: Solvent-extractable nonvolatile compounds, including dyes, organophosphorus
compounds, phenoxyacid herbicides, and carbamates in solid, and water samples
Method Selected for:  SAM lists this method for analysis of solid, aqueous liquid, drinking water, and/or
wipe samples. Aqueous liquid samples for DIMP, EMPA, IMPA, MPA, and PMPA should be analyzed
using ASTM D7597-09; aqueous liquid samples for EDEA, MDEA, and TEA should be prepared and
analyzed using ASTM D7599-09; aqueous  liquid samples for bromadiolone should be prepared and
analyzed using ASTM D7600-09; aqueous  liquid samples for thiodiglycol should be prepared and
analyzed using ASTM D7598-09. Drinking water samples for DIMP should be analyzed using EPA
Method 538.

Description of Method: This method provides reversed-phase HPLC, thermospray (TSP) MS, and UV
conditions for detection of the target analytes. Sample extracts can be analyzed by direct injection into
the TSP or onto a LC-TSP interface. A gradient elution program is used to separate the compounds.
Primary analysis may be performed by UV detection; however, positive  results  should be confirmed by
TSP-MS. Quantitative analysis may be performed by either TSP-MS or UV detection, using either an
external or internal standard approach. TSP-MS detection may be performed in either a negative
ionization (discharge electrode) mode or a positive ionization mode, with a single quadrupole MS.  The
use of MS-MS techniques is an option. The analytical range and detection limits vary depending on the
target analyte and instrument used.

Special Considerations: Refer to footnotes provided in analyte table above for special considerations
that should be applied when measuring specific analytes.

CASRN
57-12-5
Analysis Purpose:  Sample preparation, and analyte determination and measurement
Sample Preparation Technique: Midi- or micro-distillation
Determinative Technique:  Visible spectrophotometry

Method Developed for:  Metals in water, sediment, sludge, and soil
Method Selected for:  SAM lists this method for preparation and analysis of solid, aqueous liquid, and
wipe samples.
Detection and Quantitation: The method quantitation limits are 10 (ig/L for aqueous samples and 0.5
mg/kg for solid samples.

Description of Method:  Cyanide as hydrocyanic acid is released from cyanide complexes by means of
reflux-distillation, using either a midi- or micro-distillation process, and absorbed in a scrubber containing
sodium hydroxide solution. The cyanide ion in the absorbing solution is then determined
spectrophotometrically. In the semiautomated spectrophotometric measurement, cyanide is converted to
cyanogen chloride without hydrolyzing to the cyanate, by reaction with chloramine-T, at a pH less than 8.
After the reaction is complete, color is formed on the addition of pyridine-barbituric acid reagent, and
absorbance is read between 570 and 580 nanometers (nm).  To obtain colors of comparable intensity, it is
essential to have the same salt content in both the sample and the standards.

Analysis Purpose: Sample preparation, and analyte determination and measurement

Method Developed for:  Cyanide in drinking, ground, and surface waters, domestic and industrial waste

Method Selected for:  SAM lists this method for preparation and analysis of solid, aqueous liquid,
drinking water, and wipe samples.
Detection and Quantitation: The applicable range is 0.003 to 0.500 mg/L cyanide in the distillate.  This
range can be expanded by sample dilution, either by using less sample for distillation or diluting the
distillate.

Description of Method:  This method detects inorganic cyanides that are present as either simple soluble
salts or complex radicals. It may be used to determine values for both total cyanide and cyanide
amenable to chlorination (also known as available cyanide). Cyanide in the sample released as
hydrocyanic acid by refluxing the sample with strong acid. The hydrocyanic acid is distilled and
collected in an absorber-scrubber containing sodium hydroxide solution. The cyanide ion in the
absorbing solution is then determined  by automated colorimetry. For determination of cyanide amenable
to chlorination, a portion of the sample is chlorinated using sodium hypochlorite at a pH > 11 to
decompose the cyanide. Cyanide levels  are then determined in both the chlorinated sample portion of the
sample and a portion of the sample that has not been chlorinated using the total cyanide method.
Cyanides amenable to chlorination are then calculated by difference between unchlorinated and the
chlorinated aliquots of the sample.

Special Considerations: Alternate cyanide analyzer equipment may be used, provided it is used
according to the procedures described and the laboratory can demonstrate equivalent performance.

instrument used.

Description of Method: Vapor phase mercury is collected using gold-coated glass bead traps at a flow
rate of 0.3 L/min. The traps are directly desorbed onto a second (analytical) trap. The mercury desorbed
from the analytical trap is determined by Atomic Fluorescence Spectrometry.  Particulate mercury is
sampled on glass-fiber filters at a flow rate of 30 L/min. The filters are extracted with nitric acid and
microwave heating. The extract is oxidized with bromine chloride, then reduced with stannous chloride
and purged from solution onto a gold-coated glass bead trap. This trap is desorbed onto a second trap, the
second trap is desorbed, and the mercury is determined by CVAFS.

Special Considerations:  There are no known positive interferences at 253.7 nm wavelength. Water
vapor will cause a negative interference.

2 If problems occur when using this method, it is recommended that the canister Method TO-15 be used.
3 If problems occur when using this method for measurement of oxon compounds, analysts should consider use of
procedures included in "Oxidation of selected organophosphate pesticides during chlorination of simulated drinking

Analysis Purpose: Sample preparation, and analyte determination and measurement
Sample Preparation Technique:  Solvent extraction
Determinative Technique: GC-MS or HPLC

Method Developed for: Pesticides and polychlorinated biphenyls  in ambient air
Method Selected for: SAM lists this method for preparation and analysis of air samples.
Detection and Quantitation: The limit of detection (LOD) will depend on the specific compounds
measured, the concentration level, and the degree of specificity required. This method is applicable to
multicomponent atmospheres, 0.001 to 50 (ig/m3 concentrations, and 4 to 24-hour sampling periods.

Description of Method: A low-volume (1 to 5  L/min) sample collection rate is used to collect vapors on
a sorbent cartridge containing PUF in combination with another solid sorbent. Airborne particles also are
collected, but the sampling efficiency is not known.  Pesticides and other chemicals are extracted from the
sorbent cartridge with 5% diethyl ether in hexane and determined by GC-MS. For common pesticides,
HPLC coupled with a UV detector or electrochemical detector is preferable.  If analyzed by GC-MS, BZ,
dimethylphosphoramidic acid, EA2192, EMPA, IMPA, MPA, and PMPA require derivatization with a
trimethylsilyl agent prior to injection into the GC.

Special Considerations: Refer to footnotes provided in analyte table above for special considerations
that should be applied when measuring specific analytes. See Special Considerations for EPA SW-846
8270D in Section 5.2.31  for information regarding derivatization of compounds.

Analysis Purpose: Sample preparation, and analyte determination and measurement
Sample Preparation Technique:  Samples are collected using canisters.
Determinative Technique: GC-MS

Method Developed for: VOCs in air
Method Selected for:  SAM lists this method for preparation and analysis of air samples.
Detection and Quantitation: This method applies to ambient concentrations of VOCs above 0.5 ppbv
and typically requires VOC enrichment by concentrating up to 1 L of a sample volume; however, when
using current technologies, quantifications of approximately 100 pptv have been achieved with 0.5-L
sample volumes.

Description of Method: The atmosphere is sampled by introduction of air into a specially prepared
stainless steel canister (electropolished or silica-coated). A sample of air is drawn through a sampling
train comprising components that regulate the rate and duration of sampling into the pre-evacuated and
passivated canister. Grab samples also may be collected.  After the air sample  is collected, the canister
valve is closed, an identification tag is attached to the canister, and the canister is transported to the
laboratory for analysis. To analyze the sample, a known volume of sample is directed from the canister
through a solid multisorbent concentrator.  Recovery of less volatile compounds may require heating the
canister.

After the concentration and drying steps are completed, VOCs are thermally desorbed, entrained in a
carrier gas stream, and then focused in a small volume by  trapping on a cryo-focusing (ultra-low
temperature) trap or small volume multisorbent trap.  The  sample is then released by thermal desorption
and analyzed by GC-MS.

Special Considerations: If problems occur when using this method for determination of allyl alcohol, it
is recommended that Method TO-10A be used. In cases where lower detection levels are needed, use
procedures included in EPA Compendium Method TO-15: Reduction of Method Detection Limits to
Meet Vapor Intrusion Monitoring Needs (http://www.epa.gov/ttnamtil/files/ambient/airtox/TO-15-
Supplement.pdf).

Detection and Quantitation: The detection limit for formaldehyde is 0.07 (ig/sample. The working
range is 0.015 to 2.5 mg/m3 (0.012 to 2.0 ppm) for a 15-L sample.

Description of Method: This method can be used for the determination of formaldehyde using HPLC
with a UV detector. Air is sampled onto a cartridge containing silica gel coated with 2,4-DNPH, at a rate
of 0.03 to 1.5 L/min. The cartridge is extracted with 10 mL of acetonitrile and analyzed by HPLC-UV at
a wavelength of 360 nm. Ozone has been observed to consume the 2,4-DNPH reagent and to degrade the
formaldehyde derivative.  Ketones and other aldehydes can react with 2,4-DNPH; the derivatives
produced, however, are separated chromatographically from the formaldehyde derivative.

Determinative Technique:  HPLC

Method Developed for: Organonitrogen pesticides in air
Method Selected for: SAM lists this method for preparation and analysis of air samples.
Detection and Quantitation:  The detection limit for aldicarb is 1.2 (ig per sample and 0.6 (ig per sample
for carbofuran, methomyl, and oxamyl. The working ranges for aldicarb, carbofuran, and oxamyl are
listed in Table 2 of the method, and range from 0.5 to 10 times the OSHA PEL.

Description of Method: This method can be used for the determination of organonitrogen pesticides
using HPLC with a UV detector. Samples are prepared by desorbing the XAD-2 resin with 2 mL of
triethylamine-phosphate solution, rotating end-over-end for 45 minutes, and filtering. The method also
may be applicable to the determination of other organonitrogen compounds and to a broad range of
pesticides having UV chromophores, e.g., acetanilides, acid herbicides, organophosphates, phenols,
pyrethroids, sulfonyl ureas, sulfonamides, triazines, and uracil pesticides. Because of the broad response
of the UV detector at shorter wavelengths, there are many potential interferences. Those tested include
solvents (chloroform and toluene), antioxidants (butylated hydroxytoluene [BHT]), plasticizers (dialkyl
phthalates), nitrogen compounds (nicotine and caffeine), impurities in HPLC reagents (e.g., in
triethylamine), other pesticides (2,4-Dichlorophenoxyacetic acid [2,4-D], atrazine, parathion, etc.), and
pesticide hydrolysis products (1-naphthol).  Confirmation techniques are recommended when analyte
identity is uncertain.

Special Considerations: The presence of the analytes listed in the table above should be confirmed by
either a secondary HPLC column or by an MS.

Method Developed for:  Measurement of metals on wipe surfaces using ICP-AES
Method Selected for:  SAM lists this method for preparation of wipe samples.
Detection and Quantitation: The range for arsenic is 0.261 tolOS (ig/wipe; forthallium 0.136 to 50.0
(ig/wipe; for vanadium 0.0333 to 25.0 (ig/wipe.

Description of Method:  Surface wipe samples are transferred to a clean beaker, followed by the addition
of concentrated nitric and perchloric acids. The beaker contents are held at room temperature for 30
minutes, then heated at 150°C for 8 hours. Additional nitric acid is added until the wipe media is
completely destroyed. The sample is then taken to near dryness and the residue dissolved and diluted
before being analyzed.

Special Considerations: ICP-MS may also be used for the analysis of wipe samples; however, at this
time, this technique has not been evaluated for wipes. Nitric and perchloric acids are strong oxidizers and
extremely  corrosive.  Perform all perchloric acid digestions in a perchloric acid hood.  When working
with acids, use gloves and avoid inhalation or contact with skin or clothing.

Methyl fluoroacetate
CASRN
NA
453-18-9
Analysis Purpose:  Sample preparation
Sample Preparation Technique: Water extraction
Determinative Technique:  1C with electrolytic conductivity detection
Determinative Method:  EPA Method 300.1 Rev 1.0

Method Developed for:  Fluoroacetate anion in air
Method Selected for:  SAM lists this method for preparation of air samples.
Detection and Quantitation:  The detection limit is estimated to be 20 ng of sodium fluoroacetate per
injection, corresponding to a 100-uL aliquot of a 0.2-ug/mL standard.  The analytical range of this
method is estimated to be 0.01 to 0.16 mg/m3.

Description of Method:  This method was developed specifically for sodium fluoroacetate, but also may
be applicable to other fluoroacetate salts. The method determines fluoroacetate salts as fluoroacetate
anion.  A known volume  of air (e.g., 480 L was  used in validation of this method) is drawn through a
cellulose ester membrane filter to collect sodium fluoroacetate.  Sodium fluoroacetate is extracted from
the filter with 5 mL of deionized water, and the  resulting sample is analyzed by 1C using electrolytic
conductivity detection.

Special Considerations: When analyzing samples for methyl fluoroacetate (as fluoroacetate ion),
addition of base is required to assist dissociation into fluoroacetate anion.

                Section 6.0:  Selected Radiochemical Methods

A list of analytical methods to be used in analyzing environmental samples for radiochemical
contaminants during homeland security events is provided in Appendix B.  Methods are listed for each
isotope and for each sample type that potentially may need to be measured and analyzed when responding
to an environmental emergency.
 Please note: This section provides guidance for selecting radiochemical methods that have a high
 likelihood of assuring analytical consistency when laboratories are faced with a large scale
 environmental restoration crisis. Not all methods have been verified for the analyte/sample type
 combination listed in Appendix B. Please refer to the specified method to identify analyte/sample type
 combinations that have been verified.  Any questions regarding information discussed in this section
 should be addressed to the appropriate contact(s) listed in Section 4.
Appendix B is sorted alphabetically by analyte and includes the following information:

•   Analyte(s). The radionuclide(s) or contaminant(s) of interest.

    CAS RN. A unique identifier for chemical substances that provides an unambiguous way to identify
    a chemical or molecular structure when there are many possible systematic, generic, or trivial names.
    In this section (Section 6.0) and Appendix B, the CAS RNs correspond to the specific radionuclide
    identified.

•   Determinative technique.  An analytical instrument or technique used for qualitative and
    confirmatory determination of compounds or components in a sample.

    Drinking water sample methods. The recommended methods/procedures for sample preparation
    and analysis to measure the analyte of interest in drinking water samples. Methods have been
    identified for qualitative and confirmatory determination.

•   Aqueous and liquid phase sample methods. The recommended methods/procedures for sample
    preparation and analysis to measure the analyte of interest in aqueous and/or non-aqueous liquid
    phase samples. Methods have been identified for qualitative and  confirmatory determination.

    Soil and sediment phase sample methods. The recommended methods/procedures for sample
    preparation and analysis to measure the analyte of interest in soil  and sediment samples. Methods
    have been identified for qualitative and confirmatory determination.

•   Surface wipe sample methods. The recommended methods/procedures for sample preparation and
    analysis to measure the analyte of interest in surface wipe samples.  Methods have been identified for
    qualitative and confirmatory determination.

    Air filter sample methods. The recommended methods/procedures for sample preparation and
    analysis to measure the analyte of interest in air filter samples.  Methods have been identified for
    qualitative and confirmatory determination.

•   Qualitative determination method identifier. A unique identifier or number assigned to an
    analytical method by the method publisher. The identified method is intended to determine the
    presence of a radionuclide.  These methods are less precise than confirmatory methods, and are used
    when greater sample throughput and more rapid reporting of results is required.

    Confirmatory method identifier. A unique identifier or number assigned to an analytical method by
    the method publisher. The identified method is for measurement  of the activity from a particular
    radionuclide per unit of mass, volume, or area sampled.

Following a homeland security event, it is assumed that only those areas with contamination greater than
pre-existing/naturally prevalent levels commonly found in the environment would be subject to
remediation. Dependent on site- and event-specific goals, investigation of background levels using
methods listed in Appendix B is recommended.

6.1    General Guidelines

The guidelines summarized in this section provide a general overview of how to identify the appropriate
radiochemical method(s) for a given analyte-sample type combination, as well as recommendations for
QC procedures.

For additional information on the properties of the radionuclides listed in Appendix B, TOXNET
(http://toxnet.nlm.nih.gov/index.html'). a cluster of databases on toxicology, hazardous chemicals, and
related areas maintained by the National Library of Medicine, is an excellent resource. EPA's Radiation
Protection (http://www.epa.gov/radiation/radionuclides/index.html) and the Multi-Agency Radiological
Laboratory Analytical Protocols Manual (MARLAP) (http://www.epa.gov/radiation/marlap/manual.html)
Web sites provide some additional information pertaining to radionuclides of interest and selection of
radiochemical methods. Emergency response documents recently developed by EPA's Office of Radiation
and Indoor Air (ORIA) may be found at http://www.epa.gov/narel/incident guides.html.
6.1.1  Standard Operating Procedures for Identifying Radiochemical Methods

To determine the appropriate method to be used on an environmental sample, locate the analyte of
concern in Appendix B: Radiochemical Methods under the "Analyte Class" or "Analyte(s)" column.
After locating the analyte of concern, continue across the table to identify the appropriate determinative
technique (e.g., alpha spectrometry), then identify the appropriate qualitative and/or confirmatory method
for the sample type of interest (drinking water, aqueous and liquid phase, soil and sediment, surface
wipes, and air filters) for the particular analyte.

Sections 6.2.1 through 6.2.36, below, provide summaries of the qualitative and confirmatory methods
listed in Appendix B. Once a method has been identified in Appendix B, Table 6-1 can be used to locate
the method summary.

6.1.2  General QC Guidelines for Radiochemical Methods

Having data of known and documented quality is critical so that public officials can accurately assess the
activities that may be needed in remediating a site. Having such data requires that laboratories: (1)
conduct the necessary QC to ensure that measurement systems are in  control and operating correctly; (2)
properly document results of the analyses; and (3) properly document measurement system evaluation of
the analysis-specific QC.  Ensuring data quality also requires that laboratory results are properly
evaluated and the results of the data quality evaluation are transmitted to decision makers.

The level or amount of QC needed often depends on the intended purpose of the data that are generated.
Various levels of QC may be required if the data are generated during contaminant presence/absence
qualitative determinations versus confirmatory analyses.  The specific needs for data generation should be
identified. QC requirements and data quality objectives should be derived based on those needs, and
should be applied consistently across laboratories when multiple laboratories are used.  For example,
during rapid sample screening analyses, minimal QC samples (e.g., blanks, duplicates) and
documentation might be required to ensure data quality.  Implementation of the analytical methods for
evaluation of environmental samples during site assessment through site clearance, such as those
identified in this document, might require increased QC.

Some method-specific QC requirements are described in many of the  individual methods that are cited in
this manual. QC requirements will be referenced in SAPs developed  to address specific analytes and
sample types of concern. Additional information regarding QC requirements specific to radiochemical
methods is included in the MARLAP manual at: http://www.epa.gov/radiation/marlap/manual.html.
Individual methods, sampling and analysis protocols, or contractual statements of work also should be
consulted to determine any additional QC that may be needed.

                                                           Section 6 - Selected Radiohemical Methods
QC samples are required to assess the precision, bias, and reliability of sample results. All QC results are
tracked on control charts and reviewed for acceptability and trends in analysis or instrument operation.
QC parameters are measured as required per method at the prescribed frequency.  QC of laboratory
analyses using radiochemical methods includes ongoing analysis of QC samples and tracking QC
parameters including, but not limited to the following:
    Method blanks;
    Calibration checks;
    Sample and sample duplicates;
•   Laboratory control sample recoveries;
•   MS/MSD recoveries; and
•   Tracer and/or carrier yield.

Please note: The appropriate point of contact identified in Section 4 should be consulted regarding
appropriate QA/QC procedures prior to sample analysis. These contacts will consult with the EPA
coordinator responsible for laboratory activities during the specific event to ensure QA/QC procedures are
performed consistently across laboratories. EPA program offices will be responsible for ensuring that the
QA/QC practices are implemented.
6.1.3  Safety and Waste Management

It is imperative that safety precautions be used during collection, processing, and analysis of
environmental samples. Laboratories should have a documented health and safety plan for handling
samples that may contain target CBR contaminants, and laboratory staff should be trained in and
implement the safety procedures included in the plan.  In addition, many of the methods summarized or
cited in Section 6.2 contain specific requirements, guidelines, or information regarding safety precautions
that should be followed when handling or processing environmental samples and reagents. These
methods may also provide information regarding waste management. Laboratories should consult with
the responsible government agencies prior to disposal of waste materials.  Other resources that can be
consulted for additional information include the following:

An aliquot of a preserved drinking water sample is evaporated to a small volume (3 to 5 mL) and
transferred quantitatively to a tarred 2-inch planchet. The aliquot volume is determined based on a
maximum total solids content of 100 mg. The sample aliquot is evaporated to dryness in the planchet to a
constant weight, cooled, and counted using a gas proportional or scintillation counting system. The
counting system is calibrated with thorium-230 for gross alpha, and with strontium-90 for gross beta
analysis3. A traceable standards-based efficiency curve must be developed for each calibration nuclide
(Th-230 and Sr-90) based on a range of total solids content in the 2-inch planchet from 0 to 100 mg (see
method for specific recommendations and requirements forthe use of cesium-137).

Special Considerations:  Long counting time and increased sample size may be required to meet
detection limits. Sensitivity is limited by the concentration of solids in the sample. The method provides
an overall measure of alpha and beta activity, including activity for the radionuclides listed above, but
does not permit the specific identification of any alpha or beta emitting radionuclides.

Analysis Purpose: Qualitative and confirmatory analysis
Determinative Technique: Gamma spectrometry

Method Developed for:  Gamma emitting radionuclides in drinking water
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of select gamma
emitters in drinking water samples.

Description of Method:  This method is applicable for analysis of water samples that contain
radionuclides that emit gamma photons with energies ranging from approximately 60 to 2000 keV. The
method uses gamma spectroscopy for measurement of gamma photons emitted from radionuclides
without separating them from the sample matrix. A homogeneous aliquot of water is placed into a
standard geometry (normally a Marinelli beaker) for gamma counting, typically using a high purity
germanium (HP(Ge)) detector.  Detectors such as Germanium (Lithium) (Ge(Li)) or thallium-activated
sodium iodide (Nal(Tl)) also can be used.  Sample aliquots are counted long enough to meet the required
sensitivity of measurement. To reduce adsorbance of radionuclides on the walls of the counting
container, the sample is acidified at collection time. Due to its lower resolution, significant interference
can occur using the Nal(Tl) detector when counting a sample containing radionuclides that emit gamma
photons of similar energies. When using this method, shielding is needed to reduce background
interference. Detection limits are, in general, dependent on analyte radionuclide gamma-ray abundance,
sample volume, geometry (physical shape), and counting time.

Description of Method: This method covers measurement of the total soluble alpha emitting isotopes of
radium, namely radium-223, radium-224 and radium-226 in drinking water.  The method does not give an
accurate measurement of radium-226 content in the sample when other alpha emitters are present. If
radium-223 and radium-224 are present, the results can be used to provide a gross determination of
radium-226. When the total radium alpha activity of a drinking water sample is greater than 5 pCi/L, use
of Method 903.1 (Radium-226 in Drinking Water) is preferred. Radium in the water sample is collected
by coprecipitation with barium and lead sulfate, and purified by re-precipitation from EDTA solution.
Citric acid is added to ensure that complete interchange occurs before the first precipitation step. The
final barium sulfate precipitate is alpha counted to determine the total disintegration rate of the radium
isotopes.  By making a correction for the ingrowth of radon and its alpha emitting progeny for the elapsed
time after separation, one can determine radium activity in the sample.  Presence of significant natural
barium in the sample can result in a falsely high yield. Based on a 1000-mL sample and 100-minute
counting  time, the minimum detectable level for this method is 0.5 pCi/L.

Analysis Purpose:  Confirmatory analysis
Determinative Technique:  Alpha counting

Method Developed for:  Radium-226 in drinking water
Method Selected for: SAM lists this method for confirmatory analysis of drinking water samples.

Description of Method:  This method is specific for radium-226, and is based on the emanation and
scintillation counting of radon-222, the immediate decay product of radium-226. Radium-226 is
concentrated and separated from the water sample by coprecipitation on barium sulfate. The precipitate is
dissolved in EDTA reagent, placed in a sealed bubbler and stored for ingrowth of radon-222.  After
ingrowth, the radon-222 gas  is purged into a scintillation cell. When the short-lived radon-222 daughters
are in equilibrium with the parent (after ~4h), the scintillation cell is counted for activity. The absolute
measurement of radium-226  is effected by calibrating the scintillation cell system with a standard solution
of the nuclide.  There are no  radioactive interferences in this method.  Based on a 1000-mL sample and
100-minute counting time, the minimum detectable level for this method is 0.5 pCi/L.

Method Developed for:  Strontium-89, strontium-90, and total strontium in drinking water
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of aqueous/liquid
and drinking water samples for strontium-89 and analysis of drinking water samples for strontium-90.

Description of Method:  Stable strontium carrier is added to the water sample. Both strontium-89 and
strontium-90 are precipitated from the solution as insoluble carbonates. Interferences from calcium and
from some radionuclides are removed by one or more precipitations of the strontium carrier as strontium
nitrate. Barium and radium are removed by precipitation as chromates. The yttrium-90 decay product of
strontium-90 is removed by a hydroxide precipitation step.  The separated strontium-89 and strontium-90
are precipitated as carbonates, weighed for determination of the chemical recovery, and counted for beta
particle activity. The counting result, ascertained immediately after separation, represents the total
strontium activity (strontium-89 and strontium-90) plus an insignificant fraction of the yttrium-90 that has
grown into the separated strontium-90. The yttrium-90 decay product is allowed to in-grow for
approximately two weeks and then is separated with stable yttrium carrier as hydroxide and finally
precipitated as the oxalate, weighed for chemical recovery, and mounted for beta counting.  The
strontium-90 concentration is determined from the yttrium-90 activity; strontium-89 concentration is
determined from the difference.

Method Developed for: Tritium (as T2O or HTO) in drinking water
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of drinking water
and aqueous/liquid phase samples.

Description of Method: An unpreserved 100-mL aliquot of a drinking water sample is distilled after
adjusting pH with a small amount of sodium hydroxide and adding potassium permanganate.  The
alkaline treatment prevents other radionuclides, such as radioiodine and radiocarbon, from distilling with
the tritium. The permanganate treatment oxidizes trace organics that may be present in the sample and
prevents their appearance in the distillate. To determine the concentration of tritium, the middle fraction
of the distillate is used, because the early and late fractions are more apt to contain materials interfering
with the liquid scintillation counting process. A portion of this collected fraction is added to a liquid
scintillator cocktail, and the solution is mixed, dark adapted and counted for beta particle activity.  The
efficiency of the system can be determined by the use of prepared tritiated water standards having the
same density and color as the sample.

Method Developed for:  Total uranium alpha particle activity in drinking water
Method Selected for: SAM lists this method for qualitative determination in drinking water samples.

Description of Method:  This method measures total uranium alpha activity of a sample, without doing
an isotopic uranium analysis. The sample is acidified with hydrochloric acid and boiled to eliminate
carbonate and bicarbonate ions. Uranium is coprecipitated with ferric hydroxide and separated from the
sample. The uranium is then separated from other radionuclides that were carried down with the ferric
hydroxide by dissolving the hydroxide precipitate in hydrochloric acid, putting the solution through an
anion exchange column, washing the column with hydrochloric acid, and finally eluting the uranium with
hydrochloric acid. The uranium eluate is evaporated and the uranium chemical form is converted to
nitrate. The residue is transferred to a stainless steel planchet, dried, flamed, and counted for alpha
particle activity.  Since uranium is a naturally occurring radionuclide, reagents must be checked for
uranium contamination by analyzing a complete reagent blank by the same procedure as used for the
samples.  Based on a 1000- mL sample and 100-minute counting time in a single laboratory study, the
minimum detectable level for this method is 1.0 pCi/L.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible
or dissolvable material after normal digestion methods) or if there is a matrix interference problem, use
ORISE Method API 1.

Method Selected for: SAM lists this method for confirmatory analysis of drinking water,

Description of Method: This method is appropriate for the analysis of isotopic plutonium, uranium, and
thorium, together or individually, by alpha spectrometry. Plutonium-236, uranium-232, and thorium-234
tracer standards are added for the determination of chemical yields.  Samples are decomposed by nitric-
hydrofluoric acid digestion or ignition to assure that all of the plutonium is dissolved and chemically
separated from the sample by coprecipitation with sodium and ammonium hydroxide, anion exchange,
and electrodeposition.  The residues are dissolved in dilute nitric acid and successive sodium and
ammonium hydroxide precipitations are performed in the presence of boric acid to remove fluoride and
soluble salts.  The hydroxide precipitate is dissolved, the solution is pH-adjusted with hydrochloric acid,
and plutonium and uranium are adsorbed on an anion exchange column, separating them from thorium.
Plutonium is eluted with hydrobromic acid.  The actinides are electrodeposited on stainless steel discs
from an ammonium sulfate solution and subsequently counted by alpha spectrometry.  This method is
designed to detect environmental levels of activity as low as 0.02 pCi per sample. To avoid possible
cross-contamination, sample aliquot activities should be limited to 25 pCi or less.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible

weighed and mounted on a planchet for beta counting with a low background gas-flow alpha beta counter.
The chemical yield is determined gravimetrically, using calculations provided in the method.

Special Considerations: This method was developed for analysis of food, vegetation, and tissue.
Additional laboratory development and testing is necessary for application to soil, sediment, air filters,
and wipes.

Method Developed for: Americium in soil
Method Selected for:  SAM lists this method for confirmatory analysis of soil/sediment samples.

Description of Method: This method uses alpha spectrometry for determination of americium-241 in
soil, and also can be applied for determination of californium. Americium is leached from soil with nitric
acid and hydrochloric acid. Americium-243 is added as a tracer to determine chemical yield.  The soil is
processed through the plutonium separation steps using ion exchange resin according to Method Pu-11-
RC. Americium is collected with a calcium oxalate precipitation and finally isolated and purified by ion
exchange. Californium-252 and curium-244 are eluted with americium as americium is stripped off the
column. After source preparation by microprecipitation, americium-241, californium-252, and curium-
244 are determined by alpha spectrometry analysis. The counting period chosen depends on the
sensitivity required of the measurement and the degree of uncertainty in the result that is acceptable. The
lower limit of detection (LLD) for americium-241 is 0.5 mBq when counted for 1000 minutes.  In cases
where less than 100 g of sample is available, use of Pu-12-RC is recommended.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible
or dissolvable material after normal digestion methods) or if there is a matrix interference problem, use

Description of Method: This method is specific to measurement of americium isotopes in samples that
do not contain lanthanides, but also can be used for measurement of californium and curium. The method
uses microprecipitation and determination by alpha spectrometry. Americium-243 is added to the sample
to determine chemical yield. The sample is processed through separation steps using ion exchange resins.
The eluate from the ion exchange column containing americium (and all other ions, except plutonium) is
evaporated, redissolved, and loaded onto a Transuranic (TRU) Resin extraction column. Americium (and
curium and californium, if present) is separated and purified on the  column and finally stripped with
dilute nitric acid stripping solution. Microprecipitation is used to prepare for alpha spectrometry. The
method involves sample preparation steps from EML HASL-300 Method Pu-10-RC for water samples.
The LLD for total americium is 0.3 mBq when counted for 1000 minutes.

Method Developed for:  Gamma-ray emitting radionuclides in a variety of environmental matrices
Method Selected for: SAM lists this method for qualitative and/or confirmatory analysis of select
gamma emitters in aqueous/liquid, soil/sediment, surface wipes, and/or air filter samples.

Description of Method:  This method uses gamma spectrometry for the measurement of gamma photons
emitted from radionuclides without separating them from the sample matrix.  Samples are placed into a
standard geometry for gamma counting, typically using an HP(Ge) detector. Detectors such as Ge(Li) or
Nal(Tl) also can be used. The sample is placed into a standard geometry for gamma counting. Soil
samples and sludge are placed into an appropriately sized Marinelli beaker after drying and grinding the
sample for homogenization.  Air filters and surface wipes can be counted directly or pressed into a
planchet and counted. Samples are counted long enough to meet the required sensitivity of measurement.
For typical counting systems and sample types, activity levels of approximately 40 Bq are measured, and
sensitivities as low as 0.002 Bq can be achieved for many nuclides.  Because of electronic limitations,
count rates higher than 2000 counts per second (cps) should be avoided.  High activity samples may be
diluted, reduced in size, or moved away from the detector (a limited distance) to reduce the count rate and
allow for analysis. The method is applicable for analysis of samples that contain radionuclides emitting
gamma photons with energies above approximately 20 keV for germanium (Ge) (both HP(Ge) and GeLi)
detectors and above 50 keV forNal(Tl) detectors.

Contaminant isotopes are leached with nitric and hydrochloric acid.  Plutonium is removed by ion
exchange. The eluent from the plutonium separation is saved for determination of americium, curium,

highly specific for technetium in the pertechnetate form. The resin is washed with dilute nitric acid to
remove possible interferences and then it is extruded directly into a suitable liquid scintillation cocktail.
The sample is typically counted for 1 hour to simultaneously determine Tc-99 activity and the Tc-95m
radiochemical yield.  Quench/efficiency calibration curves need to be established for the liquid
scintillation spectrometer for both Tc-95m and Tc-99.

For this application, the procedure requires the use of thorium-230 for alpha counting efficiency and
cesium-137 for beta counting efficiency in the calibration of the detector.  An air filter or swipe sample is
placed onto a planchet then counted for alpha and beta radioactivity. Activity is reported in activity units
per volume of air sampled, as units of activity per surface area sampled, or as total units of activity in
cases where sample collection information is not available.

Determinative Technique: Cerenkov counting with Liquid Scintillation

Method Developed for:  Phosphorus-32 in fish and vegetation
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of soil, sediment,
wipes, and air filters.

Description of Method:  Samples up to 500 g are dry ashed at 550°C and dissolved in two portions of
nitric acid.  The sample is evaporated to half volume and transferred to a perchloric acid hood.
Concentrated nitric acid and concentrated perchloric acid are added, and the sample is evaporated to
dryness. The residue is dissolved in hydrochloric acid and filtered through a glass fiber filter. Fe-55 is
removed by precipitation with cupferron.  The solution containing phosphate is purified by passing it
through anion and cation  columns to remove possible contaminants. The purified phosphate is
precipitated as magnesium ammonium phosphate, filtered onto a glass fiber filter, and dried. The
magnesium ammonium phosphate is dissolved in nitric acid and transferred to a counting vial. P-32 is
assayed by counting the Cerenkov radiation with a liquid scintillation counter.

Special Considerations: Laboratories using this method must have a designated perchloric acid fume
hood. This method was developed for analysis offish and vegetation. Additional development and

This procedure provides screening measurements to indicate whether specific chemical analyses are
required for water, soil, vegetation, and other solids.  Liquid samples are acidified, concentrated, dried in
a planchet, and counted in a low-background proportional counter. Solid samples are dried and processed
to provide homogeneity, and a known quantity is transferred to a planchet and counted in a low-

Analysis Purpose: Qualitative and confirmatory analysis
Determinative Technique: Liquid scintillation

Method Developed for: Tritium in soil, sediment, animal tissue, vegetation, smears, and water samples
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of soil/sediment
and surface wipe samples.

Description of Method: The tritium in aqueous and solid samples is distilled using an Allihn condenser.
For solid samples, an appropriate volume of laboratory reagent water is added to facilitate distillation.
Certain solid samples may be refluxed to ensure distribution of any tritium that may be in the sample.
The sample may be spiked with a standard tritium solution to evaluate quenching and counting efficiency.
After the sample has been distilled, an aliquot of the distillate is added to a scintillation cocktail and the
sample is counted using a liquid scintillation analyzer.

Special Considerations: Other volatile radionuclides such as iodine and carbon isotopes may interfere
and may require that the sample be made alkaline using solid sodium hydroxide before distillation.
Organic impurities may interfere and may require the addition of an oxidizing agent to the sample as well
as spiking the samples with a standard tritium solution. The addition of a standard tritium solution to
each sample allows for counting efficiencies to be calculated for each individual sample.

Method Developed for: Technetium-99 in sediment, soil, smears, and water at environmental levels
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of soil/sediment,
surface wipe, and air filter samples.

Description of Method: Solid samples are leached with dilute nitric acid. The leachates are passed
through a commercially available resin column (TEVA® resin) which is highly specific for technetium in
the pertechnetate form. The technetium is absorbed onto the extraction resin. The resin is added to a
scintillation vial containing an appropriate cocktail and counted using a liquid scintillation analyzer.
Most interfering beta emitting radionuclides (including C-14, P-32, S-35, Sr-90, Y-90, and Th-234) are
effectively removed using TEVA® resin under the conditions in this procedure.

Special Considerations: Tritium may follow technetium due to the absorption of some tritium-labeled
compounds by the resin. Possible tritium interferences are eliminated by setting the technetium counting
window above the maximum energy of tritium beta particles.

Method Selected for:  SAM recommends this method for confirmatory analysis when a sample exists in
a refractory form (i.e., non-digestible or dissolvable material after normal digestion methods) or if there is
a matrix interference problem. In the event of refractory radioactive material, SAM recommends this
method for both qualitative determination and confirmatory analysis of drinking water, aqueous/liquid,
soil/sediment, surface wipes, and air filter samples.

Description of Method: Solid and unfiltered aqueous samples are dissolved completely by a
combination of potassium hydrogen fluoride and pyrosulfate fusions. Filtered aqueous samples are
evaporated to dryness followed by a pyrosulfate fusion. The fusion cake is dissolved and, for analyses
requiring uranium only, two barium sulfate precipitations are performed, and the uranium is separated
using EDTA.  For all other analyses, one barium sulfate precipitation is performed and all alpha emitters
are coprecipitated on barium sulfate.  The barium sulfate is dissolved and the actinides are separated by
extraction chromatography. An optional section is presented for the separation of americium from the
lanthanides. All actinides are coprecipitated on cerium fluoride and counted with an alpha spectrometer
system.

Method Developed for: Iodine-125 in environmental samples, such as soil, sediment, vegetation, water,
milk, filters (air or water), etc.
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of drinking water,
aqueous/liquid, soil/sediment, surface wipe, and air filter samples.

Description of Method: In this method a direct comparison is made between the sample and a source
prepared from a National Institute of Standards and Technology (NIST) traceable standard.  If it is
known, either by the sample preparation procedure or by a qualitative analysis on some device (high
resolution intrinsic planar detector) that 1-125 is the only radionuclide contributing to the observed peak,
then this method can be used as a rapid quantitative method.

The  sample is prepared by matrix specific techniques and the final sample is placed in a 16 millimeter
culture tube and counted in a 3" x 3" thin window sodium iodide (Nal) well detector attached to a pulse
height analyzer.  1-125 gamma counting rate is determined in the 25 to 35 keV energy range by pulse
height analysis. NIST traceable liquid standards are also counted in the same geometric configuration as
the samples to determine 1-125 counting efficiency.

Special Considerations: Due to the low photon energy of 1-125, the Compton scattering and x-ray
photons from other radionuclides may cause significant interferences in this procedure.

Method Developed for: Alpha particle spectra in water
Method Selected for:  SAM lists this method for qualitative determination in drinking water,
aqueous/liquid, soil and sediment, surface wipes, and/or air filter samples.

Description of Method: This standard practice covers the process that is required to obtain well-
resolved alpha spectra from water samples and discusses the associated problems. This practice is
typically preceded with specific chemical separations and mounting techniques that are included in
referenced methods. A chemical procedure is required to isolate and purify the radionuclides (see ASTM
Methods D3865, Standard Test Method for Plutonium in Water and D3972, Standard Test Method for
Isotopic Uranium in Water by Radiochemistry),  and a radioactive tracer is added to determine yield. A
source is prepared by employing electrodeposition, microprecipitation, or evaporation (depositing the
solution onto a stainless steel or platinum disc).  Electrodeposition and microprecipitation are preferred.

SAM 2010 (Revision 6.0)                            126                                 October 2010

The source's radioactivity is then measured in an alpha spectrometer according to manufacturer's
operating instructions. The counting period chosen depends on the sensitivity required of the
measurement and the degree of uncertainty in the result that is acceptable.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible
or dissolvable material after normal digestion methods) or if there is a matrix interference problem, use
ORISE Method API 1 for sample preparation instead of the methods referenced in ASTM Method D3084.

Method Developed for:  Alpha-particle-emitting isotopes of uranium in water
Method Selected for: SAM lists this method for confirmatory analysis of drinking water samples.

Description of Method:  Uranium is chemically separated from a water sample by coprecipitation with
ferrous hydroxide followed by anion exchange, and electrodeposition. When suspended matter is present,
an acid dissolution step is added to ensure that all of the uranium dissolves. The sample is acidified, and
uranium-232 is added as an isotopic tracer to determine chemical yield.  Uranium is coprecipitated from
the sample with ferrous hydroxide. This precipitate is dissolved in concentrated hydrochloric acid, or is
subjected to acid  dissolution with concentrated nitric and hydrofluoric acids, if the hydrochloric acid fails
to dissolve the precipitate. Uranium is separated from other radionuclides by adsorption on anion
exchange resin, followed by elution with hydrochloric acid. The uranium  is finally electrodeposited onto
a stainless steel disc and counted using alpha spectrometry.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible
or dissolvable material after normal digestion methods) or if there  is a matrix interference problem, use
ORISE Method API 1.

Description of Method:  This method allows for measurement of gross alpha and gross beta radiation in
water samples. The method provides an indication of the presence of alpha and beta emitters, including
the following SAM analytes:

    •   Americium-241
    •   Californium-252
    •   Cesium-137

This method recommends using a thin-window gas-flow proportional counter for counting gross alpha
and beta radioactivity.  An internal proportional or Geiger counter may also be used. An aliquot of
sample is evaporated to a small volume and transferred to a tared counting pan. The sample residue is
dried to constant weight, cooled, and reweighed to determine dry residue weight, then counted for alpha
and beta radioactivity.

Special Considerations: Ground water samples containing elevated levels of dissolved solids will
require use of smaller sample volumes.

Method Developed for: Gamma emitting radionuclides in water
Method Selected for: SAM lists this method for qualitative and confirmatory analysis of select gamma
emitters in aqueous/liquid samples.

Description of Method: The method uses gamma spectroscopy using either Ge detectors or Nal(Tl)
crystals for the measurement of gamma photons emitted from radionuclides present in water. The method
can be used for qualitative and confirmatory determinations with Ge detectors or semi-qualitative and
semi-quantitative determinations (using Nal(Tl) detectors). Exact confirmation using Nal is possible for
single nuclides or when the gamma emissions are limited to a few well-separated energies. A
homogeneous water sample is placed into a standard geometry (normally a Marinelli beaker) for gamma
counting. Sample portions are counted long enough to meet the required sensitivity of measurement. A
standard containing a mixture of gamma energies from approximately 100 to 2000 keV is used for energy
calibration.

Method Developed for: Alpha-emitting isotopes of radium in water
Method Selected for:  SAM lists this method for qualitative determination in aqueous/liquid samples.

Description of Method: This method is for determination of all alpha-emitting radium isotopes by alpha
decay analysis. Lead and barium carriers are added to the sample containing alkaline citrate, then sulfuric
acid is added to precipitate radium, barium, and lead as sulfates.  The precipitate is purified by washing
with nitric acid, dissolving in alkaline EDTA, and re-precipitating as radium-barium sulfate after pH
adjustment to 4.5. This slightly acidic EDTA keeps other naturally occurring alpha-emitters and the lead
carrier in solution. Radium-223, -224, and -226 are identified by the rate of ingrowth of their daughter
products in barium sulfate precipitate.  The results are corrected by the rate of ingrowth of daughter
products to determine radium activity. This method involves alpha counting by a gas-flow internal
proportional counter, scintillation counter, or thin end-window gas-flow proportional counter.

Method Developed for: Soluble, suspended, and total radium-226 in water
Method Selected for:  SAM lists this method for confirmatory analysis of aqueous/liquid samples.

Description of Method: Radium in water is concentrated and separated from sample solids by
coprecipitation with a relatively large amount of barium as the sulfate.  The precipitate is treated to
remove silicates, if present, and to decompose insoluble radium compounds, fumed with phosphoric acid
to remove sulfite, and dissolved in hydrochloric acid.  The completely dissolved radium is placed in a
bubbler, which is then closed and stored for a period of several days to 4 weeks for ingrowth of radon.
The bubbler is connected to an evacuation system and the radon gas is removed from the liquid by
aeration and helium, dried with a desiccant, and collected in a counting cell.  Four hours after radon
collection, the cell is counted. The activity of the radon is equal to the radium concentration.  The
minimum detectable concentration depends on counter characteristics, background-counting rate of
scintillation cell, cell efficiency,  length of counting period, and contamination of apparatus and
environment by radium-226.  Without reagent purification, the overall reagent blank (excluding
background) should be between 0.03 and  0.05 pCi radium-226, which may be considered the minimum
detectable amount under routine  conditions.

10098-97-2
Analysis Purpose: Qualitative and confirmatory analysis
Determinative Technique: Beta counting

Method Developed for: Strontium-90 or total radioactive strontium in drinking water or filtered raw
water
Method Selected for:  SAM lists this method for qualitative and confirmatory analysis of aqueous/liquid
samples.

Description of Method: A known amount of inactive strontium ions, in the form of strontium nitrate, is
added as a "carrier." The carrier, alkaline earths, and rare earths are precipitated as the carbonate to
concentrate the radiostrontium. The carrier, along with the radionuclides of strontium, is separated from
other radioactive elements and inactive sample solids by precipitation as strontium nitrate using fuming
nitric acid solution.  The carrier and radionuclides of strontium are precipitated as  strontium carbonate,
which is dried, weighed to determine recovery of carrier, and measured for radioactivity. The activity of
the final precipitate is due to radioactive strontium only, because all other radioactive elements have been
removed.  Because it is impossible to separate the isotopes of strontium-89 and strontium-90 by any
chemical procedure, the amount of strontium-90 is determined by separating and measuring the activity of
yttrium-90, its decay product.  This method involves beta counting by a gas-flow internal proportional
counter or thin end-window low-background proportional counter. A correction is applied to compensate
for loss of carriers and activity during the various purification steps.

Method Developed for: Total uranium alpha activity in water
Method Selected for:  SAM lists this method for qualitative determination in aqueous/liquid samples.

Description of Method: The sample is acidified with hydrochloric or nitric acid and boiled to eliminate
carbonate and bicarbonate ions. Uranium is coprecipitated with ferric hydroxide and subsequently
separated.  The ferric hydroxide is dissolved, passed through an anion-exchange column, and washed with
acid, and the uranium is eluted with dilute hydrochloric acid. The acid eluate is evaporated to near
dryness, the residual salt is converted to nitrate, and the alpha activity is counted by a gas-flow
proportional counter or alpha scintillation counter.

Special Considerations: If it is suspected that the sample exists in refractory form (i.e., non-digestible
or dissolvable material after normal digestion methods) or if there is a matrix interference problem, use
ORISE Method API 1.

                     Section 8.0:  Selected Biotoxin Methods

A list of methods or procedures to be used in analyzing environmental samples for biotoxin contaminants
is provided in Appendix D.  These methods should be used to support remediation activities (site
assessment through clearance) following a homeland security event. Procedures have been compiled for
each biotoxin that may need to be identified and/or quantified following a contamination incident.
Analytical procedures are not currently available for all the analyte-sample type combinations included in
this document. Future research needs include identification of additional methods as well as development
and validation of the procedures listed.  Appendix D is sorted alphabetically by analyte, within each of
two analyte types (i.e., protein and small molecule).
  Please note: This section provides guidance for selecting biotoxin methods that have a high likelihood
  of assuring analytical consistency when laboratories are faced with a large-scale environmental
  restoration crisis. Not all methods have been verified for the analyte/sample type combination listed in
  Appendix D. Please refer to the specified method to identify analyte/sample type combinations that
  have been verified. Any questions regarding information discussed in this section should be addressed
  to the appropriate contact(s) listed in Section 4.
Appendix D provides the following information:

•   Analyte(s). The compound or compound(s) of interest.

    CAS RN / Description. A unique identifier for substances that provides an unambiguous way to
    identify a toxin or toxin isoform when there are many possible systematic, generic, or trivial names
    and/or a brief statement describing the toxin.

•   Analysis type. Tests are either for presumptive identification, confirmatory identification, or
    biological activity determination; tests types are described below.

    Analytical Technique. An analytical instrument or technique used to determine the quantity and
    identification of compounds or components in a sample.

•   Analytical Method. The recommended method or procedure, and the corresponding publisher.

    Aerosol (filter/cassette or liquid impinger). The recommended method/procedure to measure the
    analyte of interest in air sample collection media such as filter cassettes and liquid impingers.

•   Solid (soil, powder).  The recommended method/procedure to measure the analyte of interest in solid
    samples such as soil and powders.

    Particulate (swabs, wipes, filters).  The recommended method/procedure to measure the analyte of
    interest in particulate sample collection media such as swabs, wipes and dust-collecting socks used
    with vacuum collection.

•   Liquid/water. The recommended method/procedure to measure the analyte of interest in liquid and
    water samples.

    Drinking water.  The recommended method/procedure to measure the analyte of interest in drinking
    water samples.

Following a homeland security event, it is assumed that only those areas with contamination greater than
pre-existing, naturally prevalent levels commonly found in the environment would be subject to
remediation. Dependent on site- and event-specific goals, investigation of background levels using
methods listed in Appendix D is recommended.

The "analysis type" listed for each biotoxin method in Appendix D is intended to address: (1) the level of
certainty of results and (2) the remediation phase (e.g., site mapping, assessment, clearance).  Presumptive
methods are intended to provide results consistent with a reasonable level of certainty and would
generally be used during remediation where a large number of samples may need to be processed (e.g.,
requiring high throughput). Immunoassays are common presumptive methods, may be adapted for large-

scale sample processing, and are listed for many of the biotoxin analytes. Confirmatory methods are
intended to provide results with a high level of certainty.  Confirmatory methods should be considered for
remediation when: (1) presumptive analysis indicates the presence of the biotoxin, (2) a smaller subset of
samples requires processing, or (3) as required for a tiered approach (e.g., algorithm) to remediation.
Several techniques are listed in Appendix D as confirmatory; these are generally more time consuming
and expensive.  The use of these terms in this document is not intended to redefine or supersede the
Laboratory Response Network's (LRN) use of these terms.  The terms presumptive and confirmatory as
used by the LRN are described in Section 8.1.4. Methods that address biological activity are intended to
provide a high level of certainty in corroborating other assay results.  Biotoxins may be detectable but
inactive (either before or after remediation); therefore these assays may also provide information about
potential impact on human safety. Biological activity may be determined directly using in vivo (e.g.,
mouse bioassay) or in vitro (e.g., enzymatic activity) methods or inferred using indirect methods (e.g.,
HPLC). However, biological availability (i.e., biotoxin accessibility to site of action) and activity are
both required to elicit toxicity and some in vitro methods may not address both parameters.  Confirmatory
procedures listed for the small molecule biotoxins involve a determination of intact compound structure
(an indication of biological activity); therefore, only presumptive and confirmatory methods are listed for
these biotoxins. Tiered approaches for specific contaminants will be described in a future revision of
SAM.

Numerous analytical techniques using a variety of instrumentation (e.g., high performance liquid
chromatography - mass spectrometer [HPLC-MS], HPLC-FL, immunoassay [enzyme-linked
immunosorbent assay (ELISA)], immunoassay [lateral flow device (LFD)], etc.) have been cited in
Appendix D.  It is expected that a reduced number of these analytical techniques and instruments will be
necessary after method verification and validation.  In addition, it is recognized that new reports detailing
advances in biotoxin analysis appear in the literature frequently. Accordingly, the individual techniques
and methods listed in Appendix D are to be regarded as a starting point; after thoughtful consideration of
current technologies at the time of remediation and consultation with the authority in charge of the
remediation activity, these techniques and methods can be modified as necessary for analysis of a
particular sample.

The presence of disinfectants (e.g., chlorine) and/or preservatives added during water sample collection to
slow degradation (e.g., pH adjusters, de-chlorinating agents) could possibly affect analytical results.
When present, the impact of these agents on method performance should be evaluated, if not previously
determined. EPA's NHSRC is working on a sample collection document that is  intended as a companion
to SAM.  This sample collection document will provide information regarding sampling container/media,
preservation,  holding time, sample size, and shipping and is intended to complement the laboratory
analytical methods that are the focus of the SAM document.

8.1.1  Standard Operating Procedures for Identifying Biotoxin Methods

To determine the appropriate method that is to be used on an environmental sample, locate the biotoxin of
concern in Appendix D: Selected Biotoxin Methods under the "Analyte(s)" column. After locating the
biotoxin, continue across the table and identify the appropriate analysis type. After an analysis type has
been chosen, find the analytical technique (e.g., immunoassay) and analytical method applicable to the
sample type of interest (aerosol, solid, particulate, liquid, or drinking water) corresponding to that
particular analyte.

Once a method has been identified in Appendix D, the corresponding method summary can be found in
Sections 8.2.1 through 8.3.12.  Method summaries are listed first by alphabetical order within each
biotoxin subcategory (i.e., protein and small molecule) and then in order of method selection hierarchy
(see Figure 2-1), starting with EPA methods, followed by methods from other federal agencies, VCSBs,
and journal articles. Where available, a direct link to the full text of the method is provided with the
method summary.  For additional information on sample preparation procedures and methods available
through consensus  standards organizations, please use the contact information provided in Table 8-1.

8.1.2   General QC Guidelines for Biotoxin Methods

Having data of known and documented quality is critical so that public officials can accurately assess the
activities that may be needed in remediating a site during and following emergency situations. Having
such data requires that laboratories: (1) conduct the necessary QC to ensure that measurement systems are
in control and operating properly; (2) properly document results of the analyses; and (3) properly
document measurement system evaluation of the analysis-specific QC. Ensuring data quality also
requires that laboratory results  are properly evaluated and the results of the data quality evaluation are
transmitted to decision makers.

The level or amount of QC needed often depends on the intended purpose of the data that are generated.
Various levels of QC may be required if the data are generated during presence/absence determinations
versus confirmatory analyses. The specific needs for data generation should be identified.  QC
requirements and data quality objectives should be derived based on those needs and should be applied
consistently across laboratories when multiple laboratories are used. For example, during rapid sample
screening, minimal QC samples (e.g., blanks, replicates) and documentation might be required to ensure
data quality.  Sample analyses for environmental evaluation during site assessment through site clearance,
such as those identified in this document, might require increased QC (e.g., demonstrations of method
sensitivity, precision, and accuracy).

While method-specific QC requirements may be included in many of the procedures that are cited in this
document, and will be referenced in any SAPs developed to address specific analytes and sample types of
concern, the following describes a minimum set of QC samples and procedures that should be conducted
for all analyses. Individual methods, sampling and analysis protocols, or contractual statements of work
also should be consulted to determine any additional QC that may be needed.  QC tests should be run as
frequently as necessary to ensure the reliability of analytical results. In general, sufficient QC includes an
initial demonstration of measurement system capability as well as ongoing assessments to ensure the
continued reliability of the analytical results.

Examples of sufficient QC for the presumptive tests listed in Appendix D include:

    Method blanks;
•   Positive test samples / negative test samples;
•   Calibration check  samples;
•   Use of test kits and reagents prior to expiration; and
•   Accurate temperature controls.

Examples of sufficient QC for the confirmatory tests listed in Appendix D include:

•   Demonstration that the measurement system is operating properly
    *•   Initial calibration
    *•   Method blanks

•   Demonstration of  measurement system suitability for intended use
    *•   Precision and  recovery (verify measurement system has adequate accuracy)
    *•   Analyte/sample type/level of concern-specific QC samples (verify that measurement system has
        adequate sensitivity at levels of concern)

    Demonstration of  continued measurement system reliability
    *•   MS/MSDs (recovery and precision)
    *•   QC  samples (system accuracy and sensitivity at levels of concern)
    *•   Continuing calibration verification
    *•   Method blanks

Please note: The appropriate point of contact identified in Section 4 should be consulted regarding
appropriate QA/QC procedures prior to sample analysis. These contacts will consult with the EPA ERLN
coordinator responsible for laboratory activities during the specific event to ensure QA/QC procedures are
performed consistently across laboratories.  EPA program offices will be responsible for ensuring that the
QA/QC practices are implemented.

8.1.3   Safety and Waste Management

It is imperative that safety precautions be used during collection, processing, and  analysis of
environmental samples.  Laboratories should have a documented health and safety plan for handling
samples that may contain target CBR contaminants, and laboratory staff should be trained in and
implement the safety procedures included in the plan. In addition, many of the methods summarized or
cited in Section 8.2 contain some specific requirements, guidelines,  or information regarding safety
precautions that should be followed when handling or processing environmental samples and reagents.
These methods also provide information regarding waste management. Other resources that can be
consulted for additional information include the following:

8.1.4  Laboratory Response Network (LRN)
The LRN was created in accordance with Presidential Decision Directive 39, which established terrorism
preparedness responsibilities for federal agencies. The LRN is primarily a national network of local,
state, federal, military, food, agricultural, veterinary, and environmental laboratories; however, additional
LRN laboratories are located in strategic international locations. The CDC provides technical and
scientific support to member laboratories as well as secure access to standardized procedures and reagents
for rapid (within 4 to 6 hours) presumptive detection of biothreat agents and emerging infectious disease
agents. These rapid presumptive assays are part of agent-specific algorithms of assays which lead to a
confirmed result. The algorithm for a confirmed result is often a combination of one or more presumptive
positive results from a rapid assay in combination with a positive result from one of the "gold standard"
methods, such as culture.  The standardized procedures, reagents, and agent-specific algorithms are
considered to be sensitive and are available only to LRN member laboratories. Thus, these procedures are
not available to the general public and are not discussed in this document.

       Description of Method:  Procedures are described for using mouse monoclonal antibodies
       (mAbs) and rabbit-derived polyclonal antibodies prepared against a mixture of abrin isozymes for
       three separate ELISA and electrochemiluminescence (ECL)-based assays in food products.  The
       three assays vary by use of antibody combination (e.g, assay configuration): (1) polyclonal
       (capture)/polyclonal (detection) ELISA, (2) polyclonal/monoclonal ELISA, and (3)
       polyclonal/monoclonal ECL assay. The LODs, with purified Abrin C and various abrin extracts
       in buffer, are between 0.1 and 0.5 ng/mL for all three assays.  The LOD for abrin spiked into food

       products ranged from 0.1 to 0.5 ng/mL, using the ECL assay.  The LOD for abrin spiked into
       food products for the ELISA assays ranged between 0.5 and 10 ng/mL depending on the antibody
       combination. In all cases, the LODs were less than the concentration at which abrin may pose a
       health concern.

       Special Considerations: Crude preparations of abrin may also contain agglutinins that are
       unique to rosary peas and that can cross-react in the immunoassays. Addition of non-fat milk
       powder to the sample buffer may eliminate false-positive results (Dayan-Kenigsberg, J.,

       Analysis Purpose: Complementary presumptive for abrin
       Analytical Technique: LC-MS-MS

       Method Developed for: Abrine in beverages
       Method Selected for: SAM lists these procedures for complementary presumptive analysis of
       abrin by abrine detection in aerosol, solid, particulate, liquid, and water samples. Abrine, an
       alkaloid present in equal concentrations with abrin in rosary peas (Abrus precatorius L.), is found
       in crude preparations of abrin and may be an indicator of abrin contamination.  Further research is
       needed to develop and standardize the procedures for environmental sample types.

       Description of Method: Procedures are described for sample extraction by SPE or liquid-liquid
       extraction, followed by tandem mass spectrometry.  The method was verified in beverages
       (bottled water, cola, juice drink, 1% low fat milk, bottled tea) spiked with abrine at either
       0.5(ig/mL or 0.05(ig/mL. These samples were prepared for LC-MS-MS by either an optimized
       SPE procedure or a liquid-liquid extraction procedure.  For SPE, optimal abrine recoveries were
       achieved with  sample pH adjusted to 2 - 6 with formic acid, inclusion of a water/methanol (95/5,
       v/v) washing step prior to elution, and use of a Strata-X SPE cartridge. Liquid-liquid extraction
       was with an equal volume (2 mL) of acetonitrile/water (75/25, v/v). Differences in recovery
       between the two extraction methods were determined using the two-sided Student's ^test,
       assuming equal variance. At 0.5 (ig/mL, recovery of abrine by SPE was significantly higher (P <
       0.01) for water and juice drink as compared to liquid-liquid extraction, but no significant
       differences were observed for cola and tea.  At 0.05 (ig/mL, the differences in recovery of abrine
       in water, tea, cola, and juice drink were highly statistically different (P < 0.001), with belter
       recoveries for the optimized SPE procedure. The method had a MDL of 0.025  (ig/mL and limit
       of quantitation (LOQ) of 0.05 (ig/mL. Storage stability was also tested for abine at 10 (ig/mL in a
       water/methanol stock solution (90/10, v/v) at three temperatures (0°C, 4°C, and 23°C). Aliquots
       were analyzed in triplicate at 0, 1, 7, and 21 days after sample preparation. There was no
       statistically significant difference between abrine standards stored at the three temperatures at 21
       days and no loss of abrine concentration.

       Special Considerations: The biotoxin methods points of contact listed in Section 4.0 of SAM
       should be consulted for additional information regarding water and drinking water analyses.

                 378(1): 87-89)

       Analysis Purpose: Biological activity
       Analytical Technique:  Enzyme activity

       Method  Developed for:  Jequirity seed (abrin) and castor bean (ricin) extracts in buffer
       Method  Selected for:  SAM lists these procedures for biological activity analysis in aerosol,
       solid, particulate, liquid, and water samples. Further research is needed to develop and
       standardize the procedures for environmental sample types.

       Description of Method:  This  in vitro assay is a ribonucleic acid (RNA) N-glycosidase enzyme
       activity assay for the detection  of purified abrin and ricin toxins (Types I and II) or in jequirity
       seed (abrin) and castor bean (ricin) extracts. Synthetic biotinylated RNA substrates with varied
       loop sequences are cleaved by either the ricin or abrin toxin and the RNA products are hybridized
       to ruthenylated-oligodeoxynucleotides to generate an ECL signal.  Assays require incubation for
       2 hours at 48°C. Commercially available ECL-based reagents and RNase inactivators are used.
       Control experiments for the jequirity seed experiments and the distinct GdAA/GdAGA ratio for
       the castor bean assay demonstrate lack of non-specific cleavage for the assay. The undiluted
       castor bean extract contained 22.0 ± 0.7 mg/mL total protein and 4.1 ± 0.3 mg/mL ricin
       equivalents as determined by standard protein determination and by ECL immunoassay assays
       respectively.  The undiluted jequirity seed extract was similarly assayed, with a resultant 21.6 ±
       0.6 mg/mL total protein and 3.7 ± 0.3 (ig/mL equivalents of toxin. Dilutions were performed to
       determine effective signal-to-background ratio and the linear range for calculation of toxin
       activity.  Resultant calculations for ricin activity equivalents in the undiluted castor bean extract
       were equivalent to those obtained with the ECL immunoassays:  4.4 ± 0.2 mg/mL activity
       equivalents. In contrast, the undiluted jequirity seed extract contained a calculated level of 740 ±
       50 (ig/mL activity equivalents,  which greatly exceeded the immunoassay-based value.

       Special  Considerations: This enzyme activity assay does not test for cell binding; cell culture
       assays are being developed to test for cell binding but are  not currently available.  The only
       readily available assay to test for both the cell binding and enzymatic activity of the intact
       (whole) toxin is the mouse bioassay.

       Description of Method:  Procedures are described for measuring the biological activity of
       ribosome-inactivating proteins using a microtiter plate format for detection of abrin in PBS.
       Nuclease-treated rabbit reticulocyte lysate containing luciferase messenger ribonucleic acid
       (mRNA) is used to measure toxin activity via inhibition of protein synthesis. The relative
       biological activity is determined by comparing luminescence levels in treated samples versus
       those of untreated controls.  The amount of luciferase translated, as measured by luminescence, is
       inversely proportional to the toxin concentration. Linear dose response curves are generated for
       abrin, with a 50% inhibition of translation at 0.5 nM. Coupling this procedure, or a modification
       of this procedure, with an immunoassay will provide more information regarding the specificity
       and toxicity of the target biotoxin.

       Special Considerations: For abrin, as well as shiga and shiga-like toxins, this assay does not
       test for cell binding; cell culture assays are being developed to test for cell binding but are not
       currently available. The only readily available assay to test for both the cell binding and
       enzymatic activity of the intact (whole) toxin is the mouse bioassay.

       with streptavidin-alkaline phosphatase. The DIG-ELISA method is a modification of the amp-
       ELISA method, with digoxigenin-labeled antitoxin IgG's substituted for the streptavidin-alkaline
       phosphatase. Toxin can be detected at approximately 10 minimum lethal doses (MLD)/mL (0.12
       to 0.25 ng/mL). High concentration samples (greater than 10,000 MLD/mL) may give a positive
       absorbance for more than one toxin type.  Further dilution of the sample will remove cross-
       reactivity.

       The mouse bioassay detects biologically active toxin using a three part approach: toxin screening;
       toxin titer; and finally, toxin neutralization using monovalent antitoxin sera. Samples are
       prepared by centrirugation for suspended solids under refrigeration, or solids are extracted with
       an equal volume of pH 6.2 gel-phosphate buffer and then centrifuged.  Toxins from
       nonproteolytic strains of C.  botulinum may need trypsin activation to be detected.  Serial dilutions
       of untreated and trypsin-treated sample fluids are injected in separate pairs of mice
       intraperitoneally (i.p.).  Mice are also injected with heated, untreated, undiluted sample. Death of
       mice, along with symptoms of botulism, confirms presence of botulinum toxin. After calculation
       of an MLD, dilute monovalent antitoxin sera types A, B, E, and F are injected into mice 30
       minutes to  1 hour before challenging them with the i.p. injection of each dilution that gave the
       highest MLD from the toxic preparation.

       Special Considerations: Immunoassays with botulinum toxins may produce  variable results
       with uncomplexed  forms of toxin.

       SNAP-25  and VAMP 2 function as substrates for botulinum neurotoxins and may be an indicator
       of botulinum neurotoxin contamination. Further research is needed to develop and standardize
       the procedures for environmental sample types.

       Description of Method: Procedures are described  for antibody-based sample extraction,
       followed by synthetic peptide cleavage and high resolution matrix-assisted laser-desorbtion
       ionization (MALDI) time of flight MS. The method is verified for stool and serum clinical
       samples obtained from an exposed individual. Botulinum neurotoxin Serotypes A, B, D, and E
       are obtained from Metabiologics (Madison, WI) and used as positive controls. Rabbit polyclonal
       antibodies specific for Serotypes A, B, E, and F are  also obtained from Metabiologics and are
       coupled to Dynabeads® Protein G beads. Twenty microliters of beads are added to 100 \\L of
       stool sample, along with a cocktail of protease inhibitors. The mixture is incubated for two hours
       at 37°C, washed in buffer, followed by a water wash. Five hundred microliters of serum sample
       is added to 100 \\L of beads and similarly incubated and washed. Protease inhibitors are not
       required for serum samples. After antibody isolation, the bead-extracted sample is incubated in a

       Analysis Purpose: Presumptive
       Analytical Technique: Immunoassay

       Method Developed for: Botulinum neurotoxins (Types A, B) and ricin in buffer or water
       samples
       Method Selected for: SAM lists these procedures for presumptive analysis in aerosol samples.
       Further research is needed to develop and standardize the procedures for environmental sample
       types other than water.

       Description of Method:  Test strips are self-contained, qualitative assays for screening
       environmental samples for the presence of botulinum toxin and ricin. After the sample is
       collected, it is transferred onto the test strip where dye-labeled antibodies detect trace amounts of
       the contaminant, as indicated by the presence of two  bands in the test result window. After 15
       minutes, the results are read visually. Botulinum neurotoxin Type A can be detected at 5 mg/L
       and Type B at 4 mg/L, 33% of the time.  Ricin toxin  can be detected at 20 mg/L, with no cross-
       reactivity to certain substances (i.e., lectin from soybeans).

       An alternative lateral flow immunochromatographic device also can be used. This device uses
       two antibodies in combination to specifically detect target antigen in solution. When a sufficient
       amount of target antigen is present, the colloidal gold label accumulates in the sample window on
       a test strip, forming a visible reddish-brown colored line.  The presence of two bands indicates a
       positive reading. Botulinum neurotoxin Type A can  be detected at 0.01 mg/L and Type B at 0.5
       mg/L, with no false negatives detected when interferents are present. Ricin toxin can be detected
       at 0.035 mg/L, with 88% accuracy.

       Lateral flow immunoassay kits have been evaluated by the EPA ETV Program using BADD™ and
       BioThreat Alert® test strips for the detection of botulinum neurotoxins Types A and B and ricin.
       Reports and information associated with these evaluations are available at:
       http://www.epa.gov/sam/pdfs/ETV-BADD091904.pdf (BADD™ test strips) and
       http://www.epa.gov/sam/pdfs/ETV-BioThreat092104.pdf (BioThreat Alert® test strips).

       Special Considerations: Immunoassays with botulinum toxins may produce variable results with
       uncomplexed form of toxin. Addition of non-fat milk powder to the sample buffer may eliminate
       false-positive results (Dayan-Kenigsberg, Bertocchi,  J.A., and Garber, E.A.E. 2008. "Rapid

       Analysis Purpose: Confirmatory
       Analytical Technique: Immunoassay

       Method Developed for: Ricin for food products
       Method Selected for: SAM lists these procedures for confirmatory analysis in aerosol, solid,
       particulate, liquid, and water samples. Further research is needed to develop and standardize the
       procedures for environmental sample types.

       Description of Method: This immunoassay is for the detection of various concentrations of
       purified ricin in food products (e.g., juice, dairy products, vegetables, bakery products,
       condiments). The immunoassay uses ECL detection in a 96-well plate format with a monoclonal
       capture antibody against ricin (19A-2C6) and either a polyclonal or monoclonal detector
       antibody. The samples and detector antibodies can be added sequentially or in combination
       during the capture step. Using the polyclonal antibody, ricin was detected at concentrations as
       low as 0.04 ng/mL.  Simultaneous addition of sample and detector antibody allowed for a
       shortened procedure with only a single 20 minute incubation with no false negatives caused by
       "hook" effects at high concentrations of ricin. Quantitation can be performed either with the
       sequential procedure or with the simultaneous procedure if it is know that the ricin concentration
       is not in the "hook" region.  The simultaneous procedure should not be used when a sample
       contains constituents that may react with the ruthenium tag. Polyclonal/monoclonal antibodies
       are commercially available as an ELISA test kit.

       Special Considerations: Crude preparations of ricin may also contain agglutinins that are
       unique to castor beans and that can cross-react in the immunoassays.

       Analysis Purpose:  Complementary presumptive for ricin
       Analytical Technique:  LC-MS

       Method Developed for:  Ricinine in human and rat urine samples
       Method Selected for: SAM lists these procedures for complementary presumptive analysis of
       ricin by ricinine detection in aerosol, solid, particulate, liquid, and water samples. Ricinine, an
       alkaloid component of castor beans, is found in crude preparations of ricin, and may be an
       indicator of ricin contamination. Further research is needed to develop and standardize the
       procedures for environmental sample types.

       Description of Method:  Procedures are described for sample extraction by SPE, isocratic
       HPLC, followed by ESI tandem mass spectrometry.  For MS analyses, protonated molecular ions
       are selected in the multiple reaction monitoring mode and quantified by isotope dilution with
       13C6-labeled ricinine as the internal reference.  Urine pools enriched with ricinine at two
       concentrations were used as quality controls for validation of the method in urine samples.  The
       calculated limit of detection was 0.04 ng/mL. In addition to the validation with urine samples,
       testing was performed on a single human urine sample (forensic), a crude ricin preparation, and
       urine samples from an animal ricinine exposure study. For the human urine sample, the
       concentration of ricinine was measured to be 4.24 ng/mL. After a series of simple extraction and
       filtration steps to provide a crude castor bean preparation, the final ricinine level  was 502 ng/mL.
       For the animal exposure study, rats were injected with ricinine at  1, 5, and 10 mg/kg, with mean
       24-hour urine concentrations of 1010, 6364, and 17,152 ng/mL, respectively. Mean 48-hour
       urine concentrations were 40, 324, and 610 mg/mL.  Stability of ricinine in human urine  was also
       tested, with ricinine found to be stable in human urine samples when heated at 90°C for 1 hour
       and when stored at 25°C and 5°C for 3 weeks.

       Description of Method: Shiga toxin (Stx) is produced by Shigella dysenteriae and Shiga-like
       toxins (Shiga toxin Types 1 [Stx-1] and 2 [Stx-2]) are produced by various Shiga-toxigenic E.
       coli (STEC). An ELISA is described for the detection of these toxins. Diluted samples are added
       to microwells coated with an anti-Shiga toxin capture antibody.  After incubation at room
       temperature, a wash is performed to remove unbound material. A second anti-Shiga toxin
       antibody is added for detection and incubation continued at room temperature. A wash is
       performed to remove unbound antibody. Enzyme conjugated anti-IgG visualization antibody,
       directed against the species from which the second anti-Shiga toxin antibody was derived, is
       added and the plate incubated then rinsed.  Substrate is added, and after incubation to develop the
       color, stop solution is added. The results are interpreted spectrophotometrically.

       particulate, liquid, and water samples. Further research is needed to develop and standardize the
       procedures for environmental sample types.

       Description of Method: Procedures are described for a rapid optical immunoassay for the
       detection of Stx-1 and Stx-2 using a commercially available kit. Fecal samples (742 specimens)
       are assayed for Shiga toxins with and without enrichment of the specimens in broth. Duplicate
       assays are applied using either the rapid optical immunoassay or a commercially available ELISA
       kit. Samples producing positive results by immunoassay are confirmed by Vero cell cytotoxicity
       assay. Sensitivities of 96.8% are achieved for direct stool sample assays.

       Special Considerations: At the time of publication, the manufacturer no longer supports this
       assay. The CDC lists possible alternative kits for identification of Shiga toxin, in Table 4 of the
       following Web site: http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5812al.htm#tab4.

       particulate, liquid, and water samples.  Further research is needed to develop and standardize the
       procedures for environmental sample types.

       Description of Method: This method is an enzyme immunoassay (EIA) using a mixture of high-
       affinity capture antibodies for identification of toxin(s) in food samples.  Samples are prepared by
       dilution in Tris buffer, centrifugation, and filtration of the supernatant through a syringe, with
       adjustment to a final pH of 7.0 to 8.0.  Samples are incubated in 96-well plates with the mixture
       of antibodies conjugated to horseradish peroxidase (HRP), and visualized with a peroxidase
       substrate.  Assay results are determined visually or using a microtiter plate reader. Test is
       considered positive for Staphylococcal enterotoxins if absorbance is >0.200 and  is considered
       negative if absorbance is <0.200. Specific toxin serotypes are not differentiated. This method
       detects from 1.3 to 3.3 ng/mL Staphylococcal enterotoxin in extracts prepared from food
       containing 4 to 10 ng/mL Staphylococcal enterotoxin.

       aliquoted at 0.5 x 105 to 1.0 x 105 cell per well in 100 (iL culture medium into a U-bottomed 96-
       well tissue culture plate.  Food samples (potato salad, canned mushrooms, hot dogs, dry milk) are
       homogenized in PBS (1:1, wt/wt), centrifuged, the supernatants diluted 1:10 in PBS, and added
       directly to sample wells containing lymphocytes. Varying concentrations of SEA can be used as a
       standard curve. The treated samples are added to the lymphocytes and incubated for two to five
       days at 37°C. On the last day either 1 (iCi of [methyl-3H] thymidine or 20 (iL of Alamar blue is
       added to the well. After 24 hours, supernatant is either harvested onto glass fiber filters and the
       beta-radioactivity counted or the color reaction of the Alamar blue treated wells is read on a plate
       reader at 570 nm. Both human and rat lymphocytes produce strong T-cell proliferation in
       response to SEA. The radioactive assay shows a significant level of proliferation (P < 0.05) as
       compared to control medium at levels as low as 0.1 pg SEA per well.  The Alamar blue assay
       detects SEA at 1 ng per well. Diluted food samples without SEA do not induce T-cell
       proliferation.

       Special Considerations:  This method was developed for SEA in selected foods and has not
       been tested with SEB and SEC or in other sample types. However, because the T-cell
       proliferation assay is not antigen specific, the method may be appropriate for SEB and SEC, both
       of which have superantigen T-cell proliferation activity.  This assay cannot identify the specific
       superantigen nor can it assess emetic activity; additional testing to determine specificity and
       assess toxin activity should be performed.

       from the column with methanol.  For detection and quantitation of total aflatoxins, fluorescence
       measurement after reaction with bromine solution is performed. For individual aflatoxins,
       fluorescence detection and postcolumn iodine derivatization are performed and quantitation is by
       LC.  Method performance was characterized using various commodities (e.g., corn) at aflatoxin
       levels over a range of 10 to 30 ng/g. This method was originally designed for the analysis of
       aflatoxins (Bi, B2, GI, and G2) in samples where cleanup was necessary to remove food
       components, such as fats and proteins; the cleanup procedure may not be necessary for analysis of

       Description of Method: Procedures are described for the selective determination in human
       plasma of a-amanitin using HPLC with amperometric detection. After extraction of plasma with
       disposable Ci8 silica cartridges, the extracts are separated by isocratic reversed-phase
       Chromatography using a macroporous polystyrene-divinylbenzene column and a mobile phase of
       0.05 M phosphate buffer-acetonitrile (91:9) at pH 9.5.  Amperometric detection is performed by
       applying an oxidation potential as low as +350 mV (vs. Ag/AgCl) to a glassy carbon electrode, in
       a thin-layer flow-cell.  The linear range for alpha-amanitin is 3 to 200 ng/mL, and the relative
       LOD in plasma is 2 ng/mL at a signal-to-noise ratio of 2. The intra-assay precision has been

       Analysis Purpose: Presumptive
       Analytical Technique: Immunoassay

       Method Developed for: a-Amanitin, ricin, and T-2 mycotoxin in food and beverages
       Method Selected for: SAM lists these procedures for presumptive analysis of a-amanitin and T-
       2 toxin in aerosol, solid, particulate, liquid, and water samples and for confirmatory analysis of
       ricin in aerosol, solid, particulate, liquid, and water samples.  Further research is needed to
       develop and standardize the procedures for environmental sample types.

       Description of Method: Commercially available ELISAs are described and assessed for
       detection of ricin, amanitin, and T-2 toxin at levels below those described as a health concern in
       food samples.  Solid food samples are prepared by washing the sample with sodium phosphate
       buffer followed by dilution with phosphate-buffered saline. Liquid beverage samples are
       prepared by dilution in sodium phosphate buffer. Amanitin samples are similarly prepared using
       water instead of buffer, and T-2 toxin samples are similarly prepared using 35% methanol in
       water instead of buffer. The prepared samples are used with commercially obtained ELISA kits
       according to the manufacturer's directions, except for the incorporation of an eight-point
       calibration curve and reading the plates at both 405 and 650 nm after 26 minutes of incubation at
       37°C. This assay detects ricin in food products at 0.01 ug/mL with acceptable background levels.
       Amanitin can be detected in food products at 1  ug/g with the ELISA.  Background responses
       occurred, but at less than the equivalent of 0.5 ppm for amanitin.  The ELISA kit will successfully
       detect T-2 toxin at targeted levels of 0.2 ug/g.  The ELISA kit successfully detects T-2 toxin at
       targeted levels of 0.2 ug/g; the immunoassay for T-2 toxin, however, shows significant
       background responses and varies up to 0.1 ppm.

       Description of Method: Procedures are described for a competitive ELISA used to detect
       brevetoxins in shellfish. The assay uses goat anti-brevetoxin antibodies in combination with a
       three-step signal amplification process: (1) secondary biotinylated antibodies; (2) streptavidin-
       HRP conjugate; and (3) chromogenic enzyme substrate.  Sample preparation for liquids is
       dilution in PBS. Sample preparation for solids (oysters) is homogenization in PBS, or extraction
       in acetone.  The working range for the assay is 0.2 to 2.0 ng/mL for diluted and undiluted liquid
       samples, and 0.2 to 2.0 ng/mL for solid samples, corresponding to 0.8 to 8.0 ug brevetoxins/100.0
       g shellfish. The method has been compared to the mouse bioassay and is equivalent in
       sensitivity.

       Description of Method: Shellfish sample homogenates are extracted with acetone, and
       centrifuged. The supernatants are combined, evaporated, and re-solubilized in 80% methanol.
       Following a wash with 95% n-hexane, the methanolic layer is evaporated, and the residue re-
       solubilized in 25% methanol and applied to a Ci8 SPE column.  Analytes are eluted with 100%
       methanol, evaporated, and re-solubilized in methanol for analysis.  Analysis of prepared samples
       is performed using HPLC-MS-MS with a mobile phase of water and acetonitrile with acetic acid.
       Analytes are detected by an MS with ESI interface.  Brevetoxins are extensively metabolized,
       with many sub-forms. This method describes multiple liquid chromatography/electrospray
       ionization mass spectrometry (LC-ESI-MS) profiles for metabolites of brevetoxins from oysters.

       procedures for environmental sample types.

       Description of Method: A biologically active fluorescein derivative ofConus geographus a-
       conotoxin (FGI) is used in solution-phase-binding assays with two purified Torpedo californica
       monoclonal antibodies (mAbs) to detect the toxin in laboratory samples. For competitive ligand-
       displacement spin-column assays, FGI was premixed with various dilutions of unlabelled ligands
       and then incubated with the two mAbs (5A1 and 8D2) at room temperature. Fluorescence is
       measured in ratio mode using cuvettes with excitation and emission monochromators set at
       gamma = 490 nm and gamma = 525 nm, respectively. The binding of FGI to the mAbs had
       apparent dissociation constants of 10 to 100 nM. The binding specificity and epitopes recognized
       by the two mAbs against a-conotoxin GI are also characterized.  Competitive displacement
       assays showed that both mAbs specifically bound a-conotoxin GI with high avidity. Cross-
       reactivity with a-conotoxins Ml and SI was not  observed for either mAb in a direct ELISA.
       With spin-column assay, however, 5A1, but not 8D2, cross-reacted at a low level (100 - 300-fold
       less avid) with these a-conotoxins. An antibody/a-conotoxin GI molar ratio of 1:1 afforded
       complete protection in mouse lethal assays.

       Description of Method: Procedures are discussed for the detection of peptides within the a-
       conotoxin molecular mass range using an HPLC-MS. A crude extract of Conus anemone venom
       sample is made using 30% acetonitrile/water acidified with 0.1% TFA, with the insoluble portion
       of the sample removed by centrirugation.  A portion of the sample extract is fractionated by size-
       exclusion chromatography in order to prepare a sample containing small peptides in the range of
       1000 to 2500 Da. Chromatography conditions are elution with 30% acetonitrile / 0.048% TFA at
       a flow rate of 0.5 mL/minute, with detection at 214 nm. Three sulfated a-conotoxins (AnIA,
       AnIB, and AnIC) can be identified by LC-MS that are within the molecular mass range of other
       a-conotoxins (i.e., 1400-2200 Da). Peptides can be quantified by reversed-phase HPLC using an
       external reference standard for each peptide.

       detector (PDA) in environmental waters. The suggested solvent range for Cylindrospermopsin is
       below 50% methanol and 30% acetonitrile.  Complex samples (culture medium) are purified on a
       Cig column with a linear gradient of 1 to 12% (v/v) methanol/water over 24 minutes at 40°C, with
       monitoring at 262 nm.  The use of Qg columns for environmental waters is suggested for removal
       of the large number of organic compounds that may be present. This method detects and recovers
       Cylindrospermopsin from spiked environmental water samples at 1 ug/L.

       particulate, liquid, and water samples.  Further research is needed to develop and standardize the
       procedures for environmental sample types other than water.

       Description of Method: Cylindrospermopsin is detected using a colorimetric immunoassay
       (competitive ELISA) procedure. A sample (0.05 mL), enzyme conjugate (cylindrospermopsin-
       HRP), and an antibody solution containing rabbit anti-Cylindrospermopsin antibodies are added to
       plate wells containing immobilized sheep anti-rabbit antibodies. Both the Cylindrospermopsin (if
       present) in the sample and cylindrospermopsin-HRP conjugate compete in solution to bind to the
       rabbit anti-cylindrospermopsin antibodies in proportion to their respective concentrations. The
       anti-cylindrospermopsin antibody-target complexes are then bound to the immobilized sheep anti-
       rabbit antibodies on the plate. After incubation, the unbound molecules are washed and decanted.
       A specific substrate is then added which is converted from a colorless to a blue solution by the
       HRP enzyme conjugate solution. The reaction is terminated with the addition of a dilute acid. The
       concentration of Cylindrospermopsin in the sample is determined photometrically by comparing
       sample absorbance to the absorbance of the calibrators (standards) at a specific wavelength (450
       nm). The applicable concentration range is 0.4-2.0 (ig/L, with a minimum detection level of 0.4
       ug/L.

       particulate, liquid, and water samples.  Further research is needed to develop and standardize the
       procedures for environmental sample types.

       Description of Method:  ELISA and protein phosphatase inhibition assays are used to detect
       microcystins in blue-green algae products. Solid samples are prepared by homogenization in
       methanol (75% in water), with centrifugation to remove solids. Immunoassays are performed on
       the prepared samples using a commercially available ELISA test kit as described by the
       manufacturer. Samples are quantitated by comparison with a microcystins-LR standard curve.
       Quantitation with the colorimetric protein phosphatase inhibition assay is based on a comparison
       with a microcystin-LR standard curve. ELISA and phosphatase assay results agree over a
       concentration range of 0.5 to 35 ug/g.  Neither assay is specific for a particular isoform.

       Method Selected for: SAM lists these procedures for confirmatory analysis in aerosol, solid,
       particulate, liquid, and water samples.  Further research is needed to develop and standardize the
       procedures for environmental sample types other than water.

       Description of Method: Procedures are discussed to test the presence of microcystin-LR, -LY, -
       LW, -LF (CAS RN 154037-70-4), and -RR in treated and untreated water samples.
       Cyanobacterial cells are separated from the water by filtration through 110-mm glass fiber grade
       C (GF/C) discs.  The cellular components collected on the discs are extracted three times with
       methanol; the collected extraction fluids are combined and dried. The residue is resuspended in
       methanol and analyzed by HPLC-PDA. The liquid portion of the filtered water sample is
       subjected to trace enrichment using a ds SPE cartridge, followed by identification and
       determination by HPLC-PDA. This procedure can detect microcystin concentrations as low as
       250 ng/L and is the basis of the World Health Organization (WHO) method for the detection of
       microcystins.

       Description of Method: Procedures are described for quantification of the two components of
       picrotoxin (picrotin [CAS RN 21416-53-5] and picrotoxinin [CAS RN 17617-45-7]) in serum
       samples. Serum samples are prepared by washing with «-hexane, followed by extraction with
       chloroform. The chloroform is evaporated and the sample is reconstituted in acetonitrile-1 mM
       ammonium acetate buffer (pH 6.4) 34:66 (v/v) for assay by reversed-phase HPLC. The effluent
       is monitored at 200 nm, and quantification is based on peak-height ratio of analyte to the internal
       standard. A linear response is obtained for both analytes (picrotin and picrotoxinin) in the range
       0.2 to 20.0 ug/mL.

       postcolumn periodate oxidation and FL detection.  Toxin groups of different net charges are
       determined separately by isocratic elution using either sodium 1-heptanesulfonate in ammonium
       phosphate (GTX-1, GTX-6, dcGTX2, dcGTXS) or sodium 1-heplanesulfonate in ammonium
       phosphate and acetonitrile (STX [CAS RN 35523-89-8], neoSTX [CAS RN 64296-20-4], dcSTX
       [CAS RN 58911-04-9]). For biological sample types, a cleanup procedure using a Ci8 SPE
       cartridge is effective in preventing false peaks. High sensitivity with detection limits ranging
       from 20 to 110 fmol are achieved as a result of reduced band broadening and optimized reaction
       conditions. This method, when applied to low-toxicity shellfish, gives higher values than the
       standard mouse bioassay.

       8.3.10.2  ELISA Kits for Saxitoxins

       Analysis Purpose: Presumptive
       Analytical Technique: Immunoassay

       Method Developed for: STX in water and solid samples (e.g., shellfish)
       Method Selected for: SAM lists these procedures for confirmatory analysis in aerosol, solid,
       particulate, liquid, and water samples. Further research is needed to develop and standardize the
       procedures for environmental sample types other than water.

       Description of Method: Saxitoxin is detected using a colorimetric immunoassay (competitive
       ELISA) procedure. A sample (0.05 mL), enzyme conjugate (saxitoxin-HRP), and an antibody
       solution containing rabbit anti-saxitoxin antibodies are added to plate wells containing
       immobilized sheep anti-rabbit antibodies. Both the saxitoxin (if present) in the sample and
       saxitoxin-HRP conjugate compete in solution to bind to the rabbit anti-saxitoxin antibodies in
       proportion to their respective concentrations. The anti-saxitoxin antibody-target complexes are
       then bound to the immobilized sheep anti-rabbit antibodies on the plate. After incubation, the
       unbound molecules are washed and decanted. A specific substrate is then added which is
       converted from a colorless to a blue solution by the HRP enzyme conjugate solution. The reaction
       is terminated with the addition of a dilute acid. The concentration of saxitoxin in the sample is
       determined photometrically by comparing sample absorbance to the absorbance of the calibrators
       (standards) at a specific wavelength (450 nm). The applicable concentration range is 0.015-0.4
       ng/mL, with a minimum detection level of 0.015 ng/mL.

       Special Considerations: This kit is not intended for other types of saxitoxin.  Cross-reactivity is
       observed with the following saxitoxin types:  dcSTX (29%), GTX 2, 3, and 5B (23%), sulfo GTX
       1 and 2 (2.0%, dcGTX 2 and 3 (1.4%), NEOSTX (1.3%), dcNEOSTX (0.6%), GTX 1 and 4
       (<0.2%). High concentrations (e.g., above 0.1 ng/mL for toxins with >20% cross-reactivity) of
       these other types of saxitoxin may produce false positive responses.

       Description of Method: Procedures are described for LC/ESI-MS analysis of TTXs in tissue
       samples from puffer fish and newts by a combination of chromatography on a reversed-phase
       column with long carbon chains (C30) and with the mobile phase containing an ion pair reagent
       (ammonium heptafluorobutyrate). The relationship between the amount of applied standard TTX
       and its peak area on the mass chromatogram (m/z 320) shows good linearity over a range of 50 to
       1000 pmol. The detection  limit of TTX in the SIM mode is estimated to be 0.7 pmol, with a
       signal to noise ratio of 2:1.

Methods listed in Appendix A (chemical methods), Appendix B (radiochemical methods), and Appendix
D (biotoxin methods) are recommended for use in assessment of the extent of contamination and the
effectiveness of decontamination following a homeland security event. For pathogen methods, please
refer to the points of contact listed in the Appendix C text box, or Appendix C in SAM 5.0.

The primary objective of this document is not necessarily to identify the "best" analytical methods, but
rather to identify appropriate methods that represent a balance between providing existing, documented,
determinative techniques and providing consistent and valid analytical results. The method  selected for
each analyte/sample type combination was deemed the most general, appropriate, and broadly applicable
of available methods. This is a living document, which can be used as a guide by EPA and EPA-
contracted laboratories tasked with analysis of environmental samples following a homeland security
event. Recommended methods are subject to change based on procedure testing and advances in
technology.

Any questions concerning the information in this  document should be directed to the appropriate point(s)
of contact listed in Section 4.

Footnotes
1  If problems occur when using this method, it is recommended that TO-10A be used.
2  LC-MS (electrospray) procedures are preferred for these analytes; however, if this technique is not available to the laboratory, GC-MS procedures using derivatization based on SW-846 Method 8270D may be used.
Sample preparation methods should remain the same.  Both electrospray LC-MS and GC-MS derivatization procedures are currently under development.
3  For this analyte, HPLC is the preferred technique; however, if problems occur, Method TO-10A must be modified to include a derivatization step prior to analysis by GC-MS.
4  For this analyte, SW-846 Method 8270D must be modified to include a derivatization step.
5  If problems occur when using this method, it is recommended that the canister Method TO-15 be used.
6  If problems occur with analyses, lower the injection temperature.
7  If problems occur when using this method, it is recommended that SW-846 Method 8321B be used as the determinative method. Sample preparation methods should remain the same.
8  If problems occur with the analysis of DIMP using EPA SW-846 Method 8321 B, use SW-846 Method 8270D.
9  If problems occur during measurement of oxon  compounds, analysts should consider use of procedures included in  Kamal, A. et al., "Oxidation of selected organophosphate pesticides during chlorination of
simulated drinking water." Water Research. 2009. 43(2): 522-534. http://www.sciencedirect.com/science/journal/00431354
10 If problems occur when using this method, it is recommended that NIOSH Method 7906 be used.
11  Laboratory testing is currently under way for speciation of Lewisite 1 using GC-MS techniques.
12 If equipment is not available, use CVAA Methods 7471B (EPA SW-846) for solid samples and 7470A (EPA SW-846) for aqueous liquid samples.
13 For this analyte, refer to EPA SW-846 Method  8271 for GC-MS conditions.
14 Water extraction, filtration, and acidification steps from the Journal of Forensic Science. 1998. 43(1): 200-202 should be used for the preparation of solid samples. Filtration and acidification steps from this journal
should be used for preparation of aqueous liquid and drinking water samples.
15 If analyses are problematic, refer to column manufacturer for alternate conditions
16 If problems occur when using this method, it is recommended that SW-846 Method 8260C and appropriate corresponding sample preparation procedures (i.e., 5035A for solid samples, and 5030C for aqueous
liquid and drinking water samples) be used.

Footnotes
1  Please note that this category does not cover all fission products. In addition to the specific radionuclides listed in this appendix, gamma-ray spectometry with a high resoution HP(Ge) detector will identify and
quantify fission products with gamma rays in the energy range of 30 keV to 2000 keV.  The sensitivity will be dependent on the detector efficiency and the gamma-ray emission probabilities (branching ratio) for the
specific radionuclide.
2  In those cases where the same method is listed for qualitative determination and confirmatory analysis, qualitative determination can be performed by application of the method over a shorter count time than that
used for confirmatory analysis.
3  If it is suspected that the sample exists in refractory form (i.e., non-digestible or dissolvable material after normal digestion methods) or if there is a matrix interference problem, use ORISE Method AP11 for qualitative
determination or confirmatory analysis of alpha radioactivity.
4  In cases where only small sample volumes (<100 g) are available, use HASL-300 Method Pu-12-RC.
5  This procedure should be used only for filters specifically designed for iodine.
6  Because tritium is not sampled using traditional air filters, this matrix is not applicable.
7  This method was developed for measurement of total uranium and does not distinguish between uranium isotopes.

       Appendix C:  Selected Pathogen Methods
Per decision of the NHSRC SAM Pathogens Committee, "Section 7.0: Selected Pathogen Methods" has
been temporarily withdrawn from the SAM Revision 6.0.  Section 7.0 is currently undergoing a
significant restructuring to better address the complexity of environmental samples in a more user-
friendly format.  End-users, expert scientists, and federal agencies are contributing to the new design
templates.

During this transition period, the following personnel can be contacted for any emergency technical
support need:

•  EPA's Office of Emergency Management, Homeland Security Laboratory Research Center, manages
   the ERLN. The pathogens contact for ERLN is: Michele Burgess (burgess.michele@epa.gov. 202-
   564-8006).
•  NHSRC SAM Pathogens Contact: Sanjiv Shah, Lead (shah.sanjiv@,epa.gov. 202-564-9522)
 Users may also refer to the SAM Version 5.0, Pathogen Methods section. SAM Revision 5.0 can be
 accessed at http://www.epa.gov/sam/. The SAM 5.0 Pathogens section is available in a searchable
 format at http://www.epa.gov/sam/searchpath.htm

Appendix D: Selected Biotoxin Methods
Note: The presence of disinfectants (e.g., chlorine) and/or preservatives added during water sample collection to slow degradation (e.g., pH adjusters, de-chlorinating agents)
could possibly affect analytical results. When present, the impact of these agents on method performance should be evaluated if not previously determined.

 Descriptions for presumptive, confirmatory, and bioloaical activity assays are provided in Section 8.0.
2 Crude preparations of ricin and abrin may also contain agglutinins that are unique to castor beans and rosary peas, respectively, and that can cross-react in the immunoassays.
3 This assay does not test for cell binding; cell culture assays are being developed to test for cell binding but are not currently available.  The only readily available assay to test for both the cell binding and
enzymatic activity of the intact (whole} toxin is a mouse bioassav.
4 Immunoassays may produce variable results with uncomplexed form of toxin.
