       The U.S. Environmental Protection Agency (EPA), Advanced Monitoring Systems
(AMS) Center of the Environmental Technology Verification Program (ETV) collaborated with
the NOWATECH DHI Water Monitoring Center (DHIWMC), a pilot ETV program in the
European Union, to conduct an international joint verification test of a passive ground water
sampler.

       This document, which is actually a compilation of three separate documents, was used by
NOWATECH and the AMS Center to jointly verify the performance of this technology. It is
composed of a process document, a verification protocol, and a test plan for joint verification.
Combined, these three documents satisfy the requirements of an EPA ETV approved verification
test/QA plan and ensure that the requirements of both programs are met.

       The verification protocol and test plan were developed by NOWATECH with input from
Battelle, EPA, and other stakeholders. Together these documents satisfy NOWATECH's
programmatic requirements.  The process document was developed by the AMS Center with
input from NOWATECH and the EPA. It was developed as a supplement to the NOWATECH
documents, to ensure that all  of EPA ETV programmatic requirements are met. All three
documents were reviewed and approved via the ETV process prior to the start of testing.

                               EXECUTIVE SUMMARY

       The Nordic Water Technology Verification Center's (NOWATECH) DHI Water
Monitoring Center (DHI WMC), a pilot Environmental Technology Verification Program (ETV)
in the European Union, and the United States Environmental Protection Agency ETV Program's
(EPA ETV) Advanced Monitoring Systems (AMS) Center are jointly verifying the Sorbisense
(vendor) GWS40 passive ground water sampler.

       Under this joint effort, NOWATECH was responsible for developing the verification
protocol, preparing the test plan including quality assurance (test/QA), testing, and generating
the verification report/verification statement in accordance with their requirements. The AMS
Center provided technical and quality assurance oversight throughout the NOWATECH process
to ensure EPA ETV requirements were also met, and facilitated reviews and audits by QA
personnel, EPA Program management, and stakeholders of the verification protocol, test plan,
testing, and verification report.  The AMS center also developed a process document to
supplement the protocol and test plan developed by NOWATECH and ensure that all of EPA
ETV programmatic requirements are met. The process document, combined with the protocol
and test plan, satisfy the requirements of an EPA approved verification test/QA plan. This
document is a compilation of these three documents.

       The purpose of this verification is to evaluate a passive ground water sampling
technology, which is capable of detecting 10 contaminants: mono-, di-, tri- and -
tetrachloroethenes, chloroethene, benzene, toluene, ethylbenzene, xylenes (BTEX), and
methyl-fert-butylether (MTBE). Passive sampling is based upon distribution of solutes
between the sampled medium, and a collecting medium. Flow of solute from one medium
to the other continues until  equilibrium is established in the system. The amount of solute in the
sampling medium is then determined analytically and can be used to calculate the concentration
in the sampled medium. This result will then be compared to results from a standard analytical
method for the contaminants of interest, providing information on the precision, accuracy, and
range of the technology being verified. Other verification parameters will include determination
of the limit of detection, and the robustness of the monitoring technology.

                 o  Verify implementation of any necessary corrective action; and
                 o  Provide a summary of the quality assurance/quality control (QA/QC)
                    activities and results for the verification reports.

1.4    NOWATECH Involvement

       NOWATECH responsibilities are based on the requirements stated in the
NOWATECH Center Quality Manual Template.1

1.5    US EPA Involvement

       A complete list of US EPA's responsibilities in the AMS Center are based on the
requirements stated in the AMS Center ETV QMP.2 The US EPA will provide technical and
quality oversight of all ETV AMS Center activities to ensure compliance with the US ETV
program requirements.

1.6    Stakeholder Committee and Expert Group Involvement

       The AMS Center's Water Stakeholder Committee is made up of buyers and users of
such technologies.  This committee assists in prioritizing the types of technologies to be
verified and in specific cases, provides testing support. It also has representatives that assist
in review of the Test/QA plans, Verification Reports, and Verification Statements. The AMS
Center Water Stakeholder Committee provided concurrence  for the Center to proceed with
testing in this area. The stakeholders have been kept apprised of progress throughout the
planning process for this test and have provided input during progress meetings on the test
design.
       In addition, the US ETV AMS Center obtains the peer review of two external peer
reviewers and one EPA peer reviewer who are not directly involved with the verification test.
The NOWATECH ETV program uses an Expert Group to perform the external peer review

of the documents and give input on the verification. For this test, the Expert Group is made
up of three individuals to fulfill the requirements of both programs. These individuals are
named with their affiliations in the Verification Protocol6 and Test Plan7.

2      QUALITY SYSTEMS

       The Battelle and DHI quality systems to be implemented for this joint verification
will conform with the specifications listed in:
               •  ANSI/ASQ E4-2004, " Specifications and Guidelines for Quality
                  Systems for Environmental Data Collection and Environmental
                  Technology Programs"4 or the comparable International Standards
                  Organization (ISO) 90015.

       Per the US EPA ETV QMP3' verification organization quality systems, such as DHFs
quality systems, are to be reviewed and approved by verification organization management,
the AMS Center Manager, and the AMS Center Quality Manager. Since not all of the
NOWATECH/DHI quality documents have been finalized, this process document will serve
to define the specific quality activities that will be performed by Battelle and DHI for this
joint verification.

3      VERIFICATION PLANNING

       In performing the verification test, DHI and Battelle will follow the technical and QA
procedures specified in the NOWATECH Verification Protocol6, NOWATECH Test Plan7,
and this process document. Because DHI is preparing the Verification Protocol, Test Plan,
conducting the testing activities, and preparing the Verification Report and Verification
Statement, the procedure and expectations of the US EPA ETV program  need to be clarified
in a document that explains the process and requirements (this  document).

       3.1  Planning the Test Design

              Initially, the verification test design process produced a Verification Protocol6
       and Test Plan7 based upon the NOWATECH and US EPA ETV processes. These two
       documents together represent the equivalent of a US ETV AMS Center Test/QA plan.

                                                                   Page 12 of 35
                                                                 Date: 2/10/2009
The protocol includes an Application and Performance Parameter Definition
Document (Appendix 3 in the Verification Protocol6) that developed relevant
parameters and ranges hereof for verification considering the vendor stated
performance, government standards, and other technologies and methods in the
market. It also evaluated existing data that has been collected to decide whether it
could be used as part of the verification or whether it could be used as the vendor
stated claims to help decide on relevant performance parameters to test during the
verification.  The Application and Performance Parameter Definition Appendix was
not jointly produced and is a specific process within the NOWATECH program;
therefore, it was not reviewed by the US EPA ETV program.  In designing this
verification test, DHI staff used consensus-accepted test design and a previously peer
reviewed US EPA ETV Test/QA Plan8. The design also takes into account
constraints of time, scheduling, and resources. All relevant activities pertaining to
environmental  data operations have been identified, as well as performance
specifications and the appropriate controls. Finally, a process document (this
document) was produced by Battelle to address the process and differences between
the programs to ensure a successful joint verification. Collectively, these three
documents (the NOWATECH Verification Protocol6, NOWATECH Test Plan7, and
Process Document for the US EPA ETV AMS Center and NOWATECH DHI WMC
Joint Verification of the Sorbisense Ground Water Sampler) are referred to as the
"testing documents".
       The US EPA ETV process utilized its Water Stakeholder Committee to guide
the test design  process. It provided concurrence for the Center to proceed with testing
in this area. The stakeholders have been kept apprise of progress throughout the
planning process for this test and have provided input during progress meetings on the
test design. The committee also identified potential peer reviewers to perform a
formal technical review of the testing documents.  The NOWATECH ETV program
uses an Expert Group to perform the external peer review of the documents and give
input on the verification. For this test, the Expert Group is made up of individuals to
fulfill the requirements of both programs.  It includes three  individuals that have
extensive experience in the field of ground water monitoring, one EPA reviewer and
two non-EPA reviewers. These reviewers have no direct involvement in the
verification test beyond providing their reviews. The comments from the reviews

       performed by the Expert Group of the testing documents and the Verification Report
       and Verification Statement will be reconciled by DHI.  The review process will utilize
       the Review Report Form produced by the NOWATECH and is included in Appendix
       C.

4      VERIFICATION TEST IMPLEMENTATION

       This technology performance verification will be implemented according to the
Verification Protocol6 and the Test Plan7 (including technical procedural documents)
prepared during planning. Generation of verification test data will not be initiated until the
approved Verification Protocol and Test Plan are in place. Any data generated before the
required documents are approved will have to be repeated. In performing the verification test,
DHI will perform an internal audit of the data collection and handling that follows the
technical and QA procedures specified in these documents, as well as, the NOWATECH
Center Quality Manual Template1. The Battelle AMS Center will perform a technical
systems audit (TSA) to be sure that these requirements are being met.
       A virtual joint kick-off meeting will be held prior to the start of the verification test to
review procedures for the test with all verification testing staff. The joint kick-off meeting
checklist is provided in Appendix B.
       Test personnel will have access to the approved testing documents, approved changes
to testing documents, and all referenced documents.  When a prescribed sequence for the
work is defined in the testing documents, work performed shall follow that sequence.
Changes to that sequence need to be documented by either amendment (planned changes) or
deviation (unplanned changes). All verification test activities will be documented. Suitable
documents  are bound notebooks (e.g. laboratory record books, or LRBs), field and laboratory
data sheets, spreadsheets, computer records, and output from instruments (both electronic and
hardcopy).  All documentation is implemented as described in the testing documents.  All
implementation activities are traceable to the testing documents and to the test personnel. The
responsibilities of specific test personnel listed in these testing documents that leave the
project before it is completed will be reassigned.
      When work cannot be implemented according to the approved testing documents,  DHI
shall be responsible for providing a written amendment or a deviation report for the test
records.  Amendments are produced for changes that are made to the testing document before

the proposed change will be made.  Amendments must be approved by the DHI WMC
Verification Responsible, the DHI WMC Internal Auditor, Battelle AMS Center Manager,
and the Battelle AMS Center Quality Manager. Following approval, the amendment will be
distributed to all internal personnel holding a copy  of the testing documents. A deviation
report is produced for any changes to the testing document that occurred during the test.
Deviation reports must be retained in the verification test records and summarized in the
Verification Report. Frequent deviations from established procedures should result in a
retrospective review of the written document and possible revision. Amendments and
deviations will include all the information displayed on the forms shown in Appendix D.
      All  persons responsible for performing verification testing and Sorbisense will receive
copies of the final versions of the Verification Protocol6 and the Test Plan7 and associated
documentation provided by DHI. Current versions of the Verification Protocol6 and the Test
Plan7 and  any applicable methods and SOPs are required to be physically in place at the
technology verification testing sites. Battelle oversight and inspection of the verification test
will be provided by the Battelle AMS Center Quality Manager and will be over the course of
one week. An audit checklist will be prepared and approved by the EPA AMS Center Project
Officer and EPA AMS Center Quality Manager. The audit checklist will be provided to DHI
prior to the audit. The audit will begin with an "In Briefing" conducted by the Battelle AMS
Center Quality Manager to specify and clarify the necessary points of the audit. Testing
during laboratory, standpipe, and field activities will be observed along with viewing the
external laboratory performing the reference analyses. To verify full implementation of the
testing documents, the inspection will include the testing process and any  documentation
associated with the process, such as sample chain of custody transfers, instrument
maintenance and calibration, sample preparation and analysis, and data records. At the
conclusion of the audit there will be an "Exit Briefing" held to discuss the findings and
corrective actions necessary. The Battelle AMS Center Quality Manager will also provide a
written report, verify the completion of any corrective actions needed, and retain a copy of
the report with permanent Battelle AMS Center Quality Manager records. The report will be
commented  on by DHI WMC and comments addressed before it is distributed. The
Assessment Reporting Form is presented in Appendix E. The EPA AMS  Center Project
Officer will  be included in the routing of the inspection results and a written copy provided to
both the EPA AMS Center Project Officer and EPA AMS Center Quality Manager.

5      ASSESSMENT AND RESPONSE

       Assessments will be planned, scheduled, conducted, and reported in order to measure
the efficacy of the Battelle and DHI WMC quality procedures and verification execution.
The testing will be audited internally by the WMC Internal Auditor in accordance with the
Verification Protocol6 and Test Plan7. The WMC Document Reviewer and Internal Auditor
equate to the Battelle AMS Center Quality Manager. The WMC Document reviewer will
perform the technical review of the Test Plan and Verification Report documents. The WMC
Internal Auditor will perform an audit based upon identified critical points. The procedure
includes two main steps:
       •   Check that the protocol/plan is prepared and followed in accordance with the
           DHI QMS and the WMC QM (horizontal audit)
       •   Check of verification/test parameters and data at the identified critical points, ie a
           vertical audit in lab, office and/or field.
Data from the testing will be controlled by the Verification Responsible and the Test
Responsible when received.  Data integrity will be controlled by the Test Responsible
(transfer of raw data to spreadsheets) and Verification Responsible (calculations as part of
evaluations) as spot checks (5% of the data).
       Monitoring of the work process to be conducted by the Battelle AMS Center Quality
Manager will be done to:
       •    Ensure satisfactory performance based  on requirements,
       •    Ensure required actions (as specified in implementation documents) are
            performed so that routine measurements meet specifications,
       •    Ensure preventive maintenance is performed and documented as specified in
            facility and study records,
       •    Ensure calibrations are performed as planned and prescribed,
       •    Ensure corrective actions are implemented and documented as planned in
            response to items of nonconformance.
       Assessment types, responsibility, and schedule for this joint verification will be as
 shown in Table 1.0, and are defined as follows:
           Quality Systems Audit (QSA), an on-site review of the implementation of the
           WMC quality procedures. This review is used to verify the existence of, and

                                              Joint Verification Process Document
                                                                Page 16 of 35
                                                              Date: 2/10/2009

evaluate the adequacy of, the internal quality system. This review will be done in
conjunction with the Technical Systems Audit.

Technical Systems Audit (TSA), a qualitative on-site evaluation of sampling
and/or measurement systems associated with a particular verification test.  The
objective of the TSA is to assess and document the acceptability of all facilities,
maintenance, calibration procedures, reporting requirements, sampling, and
analytical activities, and quality control procedures in the test. Conformance
with the testing documents and associated methods and/or Standard Operating
Procedures is the basis for this assessment.  The Battelle AMS Center Quality
Manager will prepare and use an audit checklist that is approved by the EPA
AMS Center Quality Manager.  The checklist will be available to DHI before
the audit takes place.  This review will be done in conjunction with the QSA.

Performance Evaluation Audits (PE), a quantitative evaluation of the
measurement systems used.  The type and frequency of performance evaluation
self-audits are specified in the Test plan for the joint verification test. The value
or composition of reference materials must be certified or verified prior to use,
and the certification or verification must be adequately documented. The
Battelle AMS Center Quality Manager will review results of PE audits during
the TSA;  however, it is most preferable for the PE results to be  shared with
Battelle as soon as they  are available, so that any issues can be resolved.

Audits of Data Quality, an examination of the verification data after they have
been collected and verified by project personnel. The Battelle AMS Center
Quality Manager will audit at least 10% of all verification data, including
equations and calculations.

                   Each assessment must be fully documented.  The Battelle AMS Center
              Quality Manager and the DHI WMC Verification Responsible will archive all
              assessment reports generated for this verification test.
                   Each assessment must be responded to by the appropriate level of
              management. The Battelle quality assessment reports shall require a written
              response by the person performing the inspected activity, and
              acknowledgment of the assessment by the Battelle AMS Center Test

       Coordinator.  The Assessment Reporting Form is provided in Appendix E. An
       assessment report will also be prepared by the WMC Internal Auditor and
       provided to the Battelle AMS Center test coordinator for archive.
            Corrective action must be documented and approved on the original
       assessment report, with detailed narrative in response to the assessor's finding.
       Initials and date are required for each corrective action response.
       Acknowledgment of the response will be provided by the Battelle Test
       Coordinator.
            Implementation of corrective actions must be verified by the Battelle
       AMS Center Quality Manager or the DHI Internal Auditor to ensure that
       corrective actions are adequate and have been completed.  This will be done in
       real-time if corrective actions can be immediately performed and signed off on
       the assessment report.  Alternatively, should the corrective action require
       additional approvals not immediately available on-site, the DHI Internal
       Auditor may need to repeat the inspection, as the designee of the Battelle
       AMS Center Quality Manager, in order to corroborate the implementation and
       effectiveness  of the corrective action.
5.2  Stop Work
            Assessor responsibility and authority to stop work during a verification
       test for quality considerations is delegated to DHI and Battelle.  DHI must
       ensure compliance with all applicable Danish federal, state, and local safety
       policies during the performance of verification testing.
            Should it be determined during an assessment that test objectives of
       acceptable quality cannot be achieved during performance of verification
       testing, the Battelle AMS Center is responsible for immediately notifying the
       DHI WMC Verification Responsible of the need to consider a stop work
       order. The DHI WMC Verification Responsible will then direct the staff
       accordingly. The EPA AMS Center Quality Manager will notify the EPA
       AMS Center Project Officer if work of inadequate quality is discovered.
            Documentation is required of any stop work order and the corrective
       action implemented and shall be maintained as part of the Battelle quality

             records, with a copy provided to the EPA AMS Center Project Officer and
             EPA AMS Center Quality Manager.

      5.3    Response

                  Responses to TSA adverse findings should be addressed within 10
             working days after the TSA report is completed. However, it is expected that
             findings that have a direct impact on the conduct of a verification test will be
             corrected immediately following notification of the finding.
                  Responses to each adverse finding will be documented in the assessment
             report. Ideally, assessment reports will provide space after each adverse
             finding for a response to be recorded. The response will indicate the
             corrective action taken or planned to address the adverse finding.  The
             response should be signed and dated by the staff responsible for implementing
             the corrective action.
                  Any corrective action that cannot be immediately implemented will be
             verified following completion by the Battelle AMS Center Quality Manager or
             designee.  Once all corrective action associated with an assessment report has
             been taken, the Battelle AMS Center Quality Manager or designee will initial
             the corrective action in the assessment report thus documenting verification of
             the corrective action. Any impact that an adverse finding had on the quality of
             verification test data should be addressed in the verification report.
                  The TSA report, with responses to adverse findings recorded within, will
             be sent to EPA within 10 working days after the Battelle AMS Center Quality

       custody form to meeting, review how to complete, and where to obtain form.
    •   Review deviation/amendment procedures at meeting - what to do in the middle of a
       test if testing document cannot be followed - who to notify/what forms to file.
    •   Review testing document at meeting - identify key testing procedures and critical
       steps to ensure no ambiguity or questions.
    •   Are or will there be copies of the certificates of analysis in the verification test
       records?
    •   When will PE audit be performed?  Who will perform? Has materials/equipment
       been purchased or obtained for the PE audit?  What are QC limits?  What to do if QC
       limits are not met? Who to contact?
    •   Will regular communication between DHI and Battelle be maintained? If so, how?
       Daily/weekly email updates?

TECHNICAL

    •   Emphasize to testing staff to document anything and everything that is observed about
       the technologies, particularly if there are unusual sample results (e.g., sample color).
    •   Are provisions made to handle daily preparation of solutions/standards, if necessary?
    •   Take digital photos of all test activities.

DATA/REPORTING

    •   Review data recording forms or  sheets at meeting or discuss how/where will data be
       recorded for each testing activity
    •   How are data going to be converted electronically? Are data saved in technology
       undergoing verification and then exported to Excel? Or will data be recorded
       manually by the operators? If so, how will transcription errors be avoided?
    •   Data review - who will be doing two week review for each data set collected?  If
       Battelle staff not on-site, how will data be transmitted to Battelle?
    •   Distribute and review report schedule.  Reporting should begin at the same time as
       testing.

2      INTRODUCTION

       Environmental technology verification (ETV) is an independent (third party)
       assessment of the performance of a technology or a product for  a specified
       application, under defined conditions and quality assurance.

       This verification is a joint verification with the US EPA ETV scheme and the
       Advanced Monitoring Systems Centre, Battelle, see the verification protocol
       III for details on organization and implications. The compliance of the test with
       both scheme's requirements is ensured through a process document 111.

2.4    Verification Test Organization

       The verification will be conducted as a joint verification between the Nordic
       Water Technology Verification Centers  (NOWATECH  ETV) and the U.S.

-------
        Environmental Technology verification (US ETV) Program. The verification is
        planned  and conducted to satisfy  the  requirements of  the  ETV  scheme
        currently being established by the European Union (EU ETV) and the US ETV
        program. Verification and tests will be performed by DHI as NOWATECH
        Water Monitoring Center (DHI WMC) under contract with Nordic Innovation
        Centre,  Nordic Council of Ministers.   Battelle will be participating as  the
        manager of the ETV Advanced Monitoring Systems  (AMS) Center through  a
        cooperative agreement with the U.S. Environmental Protection Agency  (EPA).

        The day to day operations of the verification and tests will be coordinated and
        supervised by DHI personnel, with the participation of the vendor, Sorbisense.
        The testing will be conducted in the DHI laboratories, H0rsholm, Denmark and
        in the field in the Copenhagen area,  Denmark. DHI will  operate the samplers
        during the verification. Sorbisense  will provide the sampling  systems,  the
        samplers and the analysis of samplers for the test. Furthermore, Sorbisense will
        provide user manuals  and operation instructions,  and will  participate in
        development of protocol and  plans  with DHI. Battelle  will ensure that  the
        verification and tests is planned  and conducted to satisfy the requirements of
        the  US  ETV program, including  obtaining input and concurrence from its
        stakeholder group, as  described in the process document 111. Battelle will also
        participate in the development of the plan document for the verification and
        tests and perform quality assurance  of the verification  and tests.   EPA will
        participate in quality assurance of the verification and tests.

        An  expert  group  is established to provide independent expert  review of the
        planning, conducting and reporting of the verification  and  tests.

        The  organization chart in  Figure 1  identifies the  relationships  of  the
        organization associated with this verification and tests.

       Verification and tests will be conducted in two separate steps, as required by
       the EU ETV. The steps in the verification are shown in Figure 2.

       Figure 2 Verification steps
       References for the verification process are the Quality Management Plan for
       the Battelle AMS /3/ and the Quality Manual for the ETV operations at DHI
       following the NOWATECH Quality Manual Template /4/.

       A joint US EPA ETV and NOWATECH ETV verification statement will be
       issued after completion of the verification. Ensuring the compliance of the
       verification  with  the US ETV  requirements is done following  a  process
       document developed by Battelle AMS.

       This verification protocol, the test plan and the process document shall be seen
       as one consolidated verification description.
       DESCRIPTION OF THE TECHNOLOGY

       The technology product to be verified is applying the technology of passive
       sampling.

-------
        Passive sampling is based upon distribution of solutes between the sampled
        medium, e.g. a water body, and a collecting medium, the sampler or sampling
        medium.  Flow  of solute  from one  medium to the  other continues until
        equilibrium is established in the system,  or  until  the sampling session  is
        terminated by the user. The amount of solute in the  sampling medium is then
        determined analytically and can be used to calculate the concentration in the
        sampled medium.  With exposure until  equilibrium,  the sampled  medium
        concentration can  be calculated based  on the solute distribution between the
        two media involved as obtained by e.g. experimental calibration of the device.
        With exposure until the sampling session is terminated by the user (before
        achieving equilibrium), the time-weighted average solute concentration in the
        sampled medium can be determined from the exposure time and the sampling
        rate for the solute in question.

        A wide range of products are available for passive sampling (equilibrium based
        and rate controlled) of solutes (inorganic and organic) from waters.
4       DESCRIPTION OF THE PRODUCT

        The Sorbisense passive sampler combines the principle of passive sampling
        with a patented tracer based calculation of the amount of water that the sampler
        has been  exposed to.  The sampler  consists  of a polypropylene cartridge
        containing, see Figure 3:

           •  A sorbent that absorbs solutes from water passing the sampler.

           •  Tracer  salt that dissolves  proportionally with  the volume of water
              passing the cartridge.

           •  Filters between sorbent and tracer salt compartments.

          Rlter
        When the sampling  period  is  over, the Sorbisense sampler  is sent to a
        laboratory for extraction and analyses whereupon time-weighted average solute
        concentration is reported.

        For analysis, the cartridge is cut and the sorbent taken for batch extraction with
        acetone followed by  quantification of sorbed compounds by headspace GC-

-------
MS. The tracer salt (calcium citrate) is taken for extraction with 0.2 M HC1 and
quantification of extracted calcium with ICP.

  The sampled water volume is calculated from:
   V =
start ,tracersalt     lab ,tracersalt
        ~K
  The solute water concentration is calculated from:
   C=MsoluJV =
                         Msolute*K
                    start,tracersalt     start ,tracersalt
V= water volume in L; Mstart: tracersalt = weighed amount of salt in production as
mg Ca; Miab, tracersalt = extracted amount of salt in laboratory as mg Ca; C =
VOC concentration  in ug/L; Msoiute   = mass of VOC  detected  in  ug;  K =
solubility of the salt with the standard calibration value as 184 mg Ca/L.

The  product to be verified here is the Sorbisense GWS40 sampling system
intended for sampling of shallow groundwater and equipped with samplers for
volatile organic compounds.

Figure 4 Mounting of the GWS40 sampling system
The GWS40 is mounted with air hose, safety string and Sorbisense samplers
(can be  mounted in top and  bottom  of the  GWS40) and  is  subsequently
lowered to the desired measuring depth, see Figure 4. The water pressure will
push water through the sampler slowly filling the GWS40. The air hose enables
the air inside the GWS40 to escape to the atmosphere. When the measuring
period is over, the samplers are removed and sent to the laboratory for analysis.

-------
       APPLICATION AND PERFORMANCE PARAMETER
       DEFINITIONS
        The application is defined as detailed in the application definition appendix,
        Appendix 3,  in terms of matrix/matrices for use, targets of monitoring and
        effects.

        The passive  sampler is supplied by the vendor as combined sampling and
        analysis, and the verification shall accordingly see these two steps as one.

5.1     Matrix/matrices

        The matrix of the application is groundwater and the field of application is
        investigations  of (potentially)  contaminated  groundwater  (groundwater
        investigations).

5.2     Target(s)

        The targets  of the product  are volatile organic contaminants (VOC),  here
        mono-, di-, tri- and -tetrachloroethenes, benzene, toluene, ethylbenzene and
        xylenes (BTEX) and methyl-fert-butylether (MTBE), see Table 1.

5.3     Effects

        The effects for the  application are set in terms of limit of detection (LoD),
        precision, trueness, range of application and robustness.

5.4     Performance parameters for verification

        The ranges of performance relevant for the application, as derived in Appendix
        3, are presented in Table 2. These ranges are used for planning the verification
        and testing only.  For Sorbisense VOC sampling, concentrations above 2,000
        |ig/L are not likely to be measurable (vendor information) and are not included
        in the verification. The calculation of the performance parameters explaining
        their principle is given in Table 5.

Limit of detection shall be evaluated from the standard deviation of replicate
measurements at less than 5 times the detection limit evaluated and will reflect
a less than 5% risk of false blanks.

Precision shall be evaluated under repeatability and reproducibility conditions.
Repeatability is obtained as the standard deviation of measurements done with
the same measurement procedure,  same operators, same measuring system,
same operating conditions  and same location, and replicate measurements on
the same or  similar objects over a short period of time. Reproducibility is
obtained as the standard deviation of measurements that includes  different
locations, operators, measuring systems, and replicate measurements  on  the
same or similar objects. In laboratory terminology, repeatability is the within
series precision and the reproducibility the between series precision.

Trueness is  the  correspondence between (mean)  concentrations  found  in
measurements and corresponding true concentrations.

In addition to conventional trueness, the trueness of time-weighted  averages
obtained with the sampler shall be verified.

The range of application is the  range from the LoD to the highest concentration
with linear response.

The parameters of robustness to be verified are sampling depth, sampling time,
sampling concentration and groundwater ionic strength. Robustness is  basically
the trueness as found for different values of the robustness parameters.

The  version  of the product to be verified is designed for sampling shallow
aquifers, i.e.  with  sampling depths from 0.5 to  5 m below groundwater table
(mbgw). The pressure  on samplers will vary  with  depth  to  the  sampling
positions, and pressure variations in the range  of 1.05-1.5  atmosphere shall
accordingly be verified.

Sampling time variations  from 3  to  9 days shall  be verified covering  the
different sampling times recommended by the  vendor,  as the  exposure time
may impact the performance.

-------
        In  investigations  of contaminated groundwater, both  uncontaminated and
        strongly contaminated  groundwater  will be  included.  The  concentrations
        verified shall therefore reflect the range from uncontaminated groundwater to
        highly contaminated groundwater, with at the least 3  concentrations distributed
        over a relevant range.

        In  order to reflect the varying ionic  strength of groundwaters, groundwater
        ionic strengths within the range 10-100 mS/m shall be verified, corresponding
        to the 5-95 percentile of Danish groundwaters 151.

        Information on  the  analytical performance for the  sampler analysis will be
        obtained from the responsible laboratory for comparison.

        Impact of other  factors such as  groundwater flow, well construction  or
        presence of other contaminants than the targets can not be ruled out and should
        be  considered in planning the tests for the verification.

5.5     A dditional parameters

        Besides the performance parameters to be obtained by testing,  compilation of
        parameters describing users manual, product costs and occupational health &
        safety issues of the product are required as part of the verification.
6       EXISTING DATA

        A test of Sorbisense samplers, similar but earlier product version, for volatile
        organic  contaminants in groundwater wells has  been conducted by  the
        laboratory used by the vendor for sampler analysis.

6.1     Summary of existing data

        The summarized data as provided by the manufacturer is presented in Figure 5.

        The  test  was  set  up  with  polyvinylchloride  (PVC)  pipes  simulating
        groundwater wells (standpipes), filled  with  spiked water and equipped with
        Sorbisense  samplers  inserted directly  into  the water  using a  pipe adaptor
        ("pipe"),  Sorbisense samplers mounted in GWS samplers ("GWS") and water
        samples taken directly from the pipe ("water samples").

6.2     Quality of existing data

        It is not stated  whether the testing  and  analysis were done  under the
        laboratory's ISO 17025  accreditation  161, the  test laboratory can  not  be
        considered independent,  and  the  documentation  made  available  for the
        verification is not sufficient to allow for an assessment of the data quality.

6.3     Accepted existing data

        It was decided that the existing data shall not be used as part of the verification
        due  to the data quality issues, see  Section 6.2. The data will be used as an
        indication of the performance range to be expected during planning.
        TEST PLAN REQUIREMENTS
       Based upon the application and performance parameter identification, Section
       0, the requirements for test design have been set, see below. The detailed test

-------
        plan is prepared separately based upon the  specification of test requirements
        presented below.
7.1     Test design

        The outline of the required tests is shown in Table 3. The principle behind the
        design is that three test scales  are used: laboratory tests, standpipe tests and
        field tests. Each scale is further described below and provides information  on
        specified performance parameters,  with the smallest  scale chosen  for  each
        parameter in order to maintain simplicity and controlled conditions in the test.

        Table 3 Test design scales and associated performance parameters

        As an example of the application of the scale principle, consider the test for
        evaluation of trueness  and robustness. Trueness  as best possible estimate is
        evaluated from direct application at the laboratory scale (chloroethene  only).
        Trueness as realistic estimate is evaluated from the stand pipe scale simulating
        a groundwater well (all  but chloroethene),  and the  variation in trueness
        between  groundwater  wells (robustness)  is  evaluated at  the field  scale.
        Combining the  scales  thus provides the  best  possible  estimates  of real
        conditions performance.

        The laboratory tests shall  apply direct application of standard solution  to the
        samplers (best possible) or exposure of samplers to spiked water from a sample
        dispenser (robustness and  trueness). The laboratory tests provides information
        on the response of the  samplers to carefully controlled parameters and best
        possible information on the performance of the samplers with chloroethene, a
        compound that can not be  included  in standpipe tests due  to  practical and
        health and safety considerations.

        The standpipe test is intended to simulate ground water movement through a
        well  established  in the  laboratory  and to  enable  full  control  of  solute
        concentrations. The standpipe test provides more realistic information on the
        performance  of the samplers,  while  minimizing the variability of  the test
        system as compared to field systems.

        The field tests shall provide information on the robustness  of the sampling
        system under the real conditions of groundwater investigations. In planning the
        field tests, varying aquifer and well conditions should be aimed at in  order to
        allow for consideration of  any impact of factors such as groundwater flow, well
                                       10

-------
        construction or presence of other contaminants than the targets, as well as the
        impact of combined variation of robustness parameters.

7.2     Reference analysis

        Reference analysis must be done under ISO  17025 accreditation 161 using a
        GC-MS-SIM  P&T method (EPA  624.2 or  equivalent 111)  and must be
        documented to  satisfy  the analytical  requirements  set  for  groundwater
        investigations in  Denmark, see Table 4 and the application and performance
        parameter definitions, Appendix 3.

7.3     Data management

        Data storage, transfer and  control must be done in accordance with the
        requirements of ISO 9001 /8/ enabling full control and retrieval of documents
        and records. The filing and archiving requirements of the DHI Quality Manual
        must be followed (10 years archiving).

7.4     Quality assurance

        The quality assurance of the tests must include control of the reference system,
        control of the test system and control of the data quality and integrity.

        The test plan and the test report will be subject to review by the expert group as
        part of the review of this verification protocol and the verification report, see
        Figure 2.

        As this verification is a joint verification with the US EPA ETV, auditing from
        Battelle AMS Center is to be included in the test quality assurance.

7.5     Test report

        The test report must follow the principles of template of the DHI NOWATECH
        verification center quality manual template /4/ with data and records from the
        tests presented. For this joint verification, the principles (contents) of the US
        ETV format must be complied with as well.
8       EVALUATION

        The evaluation includes calculation of the performance parameters, see Section
        5.4 for definition, evaluation of the  data quality based upon the test quality
        assurance, see Section 7.4 for requirements, and compilation of the additional
        parameters as specified in Section 5.5.
                                      11

-------
 8.1     Calculation of performance parameters
          Calculations  are  done  according to generally  accepted statistical principles
          such as those described in 191 and as described in Table 5, referring also to the
          test design shown in Table 3.

Explanations
The test requires that the
variances are equal, v is n+m-2,
and sd is the standard deviation of
the difference between the two
means.
        For field measurements, the reference measurements will be used as the true
        values.

        For laboratory and  standpipe measurements,  concentrations obtained  from
        preparation of the matrices are checked against the reference measurements
        (reference  samples).  If preparation based concentrations match the reference
        measurements, mean trueness within  100% ± 2 x RSD (relative  standard
        deviation), these are  used  as true values for the test  measurements. If not, the
        reference measurements are used as the true values.

        Calculations will be  performed in Excel 2007 set up for the purpose with the
        equations required.

8.2     Evaluation of test data quality

        The information of the test report on the reference system, the test system and
        data quality and integrity control will be evaluated against the requirements set
        in this protocol and the objectives set in  the test plan.

        The spreadsheet used for the calculations will  subject to control on a sample
        basis (spot validation).

        The external audit reports prepared by  Battelle AMS Center, see  Section 7.4,
        will be evaluated and major findings compiled and reported.

8.3     Compilation of additional parameters

8.3.1   User manual
        The verification criterion for the users manual is that it describes the use of the
        samplers adequately  and understandable for the typical  sampler and sampling
        planner.  This criterion is evaluated through evaluation of a number of specific
        points of importance, see Table 6 for the parameters to include.

        A  description is complete, if all  essential steps are  described,  if they are
        illustrated with a figure or a photo, where relevant, and if the descriptions are
        understandable without reference to other guidance.

Application and performance parameter definitions
                25

-------
This appendix defines the application and the relevant performance parameters
application as input for verification and test of an environmental technology
following the NOWATECH ETV method.

1       Applications

The intended application of the product for verification is defined in terms of
the matrix, the targets and the effects of the product.

The  Sorbisense GWS40 passive sampling  system with samplers (cartridges)
and analysis of the samplers is provided by  the vendor as one product, and the
verification shall accordingly see these two investigation steps as one.

1.1     Matrix/matrices

The matrix of the application is groundwater and the field of application is
investigations on  (potentially)  contaminated   groundwater  (groundwater
investigations). In groundwater  investigations, the groundwater composition
generally varies  considerably, and the pressure on samplers will vary with
depth to the  sampling positions.  The varying  ionic strength, contaminant
concentration and water pressure may impact the performance and this impact
shall be evaluated as part of the verification.

1.2     Target(s)

The targets of the application are volatile organic contaminants, here mono-,
di-,  tri- and -tetrachloroethenes,  BTEX and  MTBE.  Investigations of
contaminated groundwater generally include both uncontaminated and strongly
contaminated  groundwater. The concentrations  verified  shall accordingly
reflect the  range from  uncontaminated groundwater to highly contaminated
groundwater. With the claimed application at sampling depths from 0.5 mbs to
5 mbs (m below surface), pressure variation  in the range 1-1.5 atmosphere shall
be verified. Furthermore,  with  the  claimed  application, groundwater  ionic
strengths within the range 10-100 mS/m shall be verified, corresponding to the
5-95 percentile of Danish groundwaters 151.

1.3     Effects

The  effects for  the  application  are  generally reported in  terms of limit of
detection (LoD), precision,  trueness, range  of application and robustness. The
effects claimed by the  vendor are given in Appendix table 1 for  all  target
compounds.

The robustness is the change  in trueness within the range  of application for
defined variations in water pressure, contaminant concentration, groundwater
ionic strength and sampling time.

Exclusions
Passive sampling at waste  disposal  sites is  excluded from  the defined
application and is thus not covered by the verification, as the conditions with
respect to  ionic  strength  and DOC are outside the  ranges  covered by the
verification conditions. Groundwater baseline monitoring and drinking water
control are excluded as well,  as the passive  sampler  will not satisfy the
detection limit requirements for this purpose, see Chapter 0.

2       General performance Requirements

No formal performance requirements for the application have been identified in
the European Union or the US.

The  conventional  performance  parameters of  analytical  and monitoring
methods and equipment are limit of detection (LoD), precision (repeatability
and reproducibility), trueness, specificity, linearity and matrix sensitivity.  The
uncertainty of measurements may  be used to summarize the performance.
Parameters may be added to characterize e.g.  on-line or on-site monitoring
instruments. The listed parameters cover the requirements set or  implemented
in international standards and by testing and verification operators 112-161.

2.1     Regulatory requirements

The general requirement for analytical quality in water monitoring in Europe
will be established with the adoption of the Commission Directive on technical
specifications for chemical analysis and  monitoring of  water status  111/
requiring not more  than 25% relative  standard  deviation at the level  of the
relevant water quality standards. The limit of quantification, LoQ,  must be at or
below  30% of the relevant water quality standard (WQS), corresponding  to a
limit of detection at or below 10% of the WQS. The LoQ is as defined in  ISO
6107-2: 2006 /18/.  The Groundwater Directive 1191  only  sets an  absolute
requirement for  monitoring of tri- and tetrachloroethene during  groundwater
                              27

-------
        monitoring  without  stating  the  water quality  standard  and  the  quality
        requirement.

        The  European  Directive  on  drinking  water  /20/  defines  performance
        requirements for methods used for control of drinking water quality for the
        VOCs  benzene, tri- and tetrachloroethene, among others.  These values  cover
        the chemical analysis only, and quality requirements for drinking water control
        would  mostly be  seen  as  stricter than for groundwater  investigations. The
        drinking water based performance  requirements for analysis only should
        therefore be seen as strict compared to groundwater monitoring including also
        sampling, see Appendix table 2.

        The Monitoring Certification Scheme of the British Environment Agency does
        not  provide performance  standards  for groundwater  or  drinking  water
        monitoring/127.

        Danish statute on quality requirements for environmental control 1211 specifies
        the requirements  for  control  and  monitoring of  mono-,  di-, tri-  and -
        tetrachloroethenes and benzene in groundwater as shown in Appendix table 3.
        The detection limits stated are not justified by the maximum concentrations for
        groundwater, except for for chloroethene, see Section 2.2.

        Again, it should be noted that the requirements cover analysis only and must
        thus be seen as stricter than required for methods including  sampling.

concentrations  to be  monitored  will  in  most cases  be  defined  by  the
groundwater maximum concentrations (and as a lower limit the drinking water
maximum concentrations) for the compounds in question, see Appendix table
4.

A general  requirement for  the limit of detection of  1/10  of the maximum
concentration  is  applied  widely,  and  the derived limits  of detection  are
compiled in Appendix table 5.  Required  detection limits for both drinking
water and groundwater control are in the same ranges in Austria.

For the Danish groundwater monitoring program (GRUMO), requirements for
detection limits are as given in Appendix table 5 7247. It should be noted, that
the detection limits required here for groundwater monitoring do not comply
with those required in Danish statute on quality requirements for environmental
control 7217 covering also monitoring of the compounds in groundwater as
shown in Appendix table 5.

       Application based requirements for trueness and precision have generally not
       been stated to the same degree as for the limits of detection, mainly because
       regulatory compliance  rules in most cases do not  consider the uncertainty of
       control results.

       No requirements for range of application and robustness have been identified.
       In practical performance of site  investigations, the dissolved  concentrations
       range from below detection limit  to the limit of solubility. The upper limit of
       concentrations to be monitored will thus in most cases be  defined by the
       solubilities of the target compounds are summarized in Appendix table 6.

       Whereas a broad range of studies on the performance of analytical methods and
       sampling methods for VOC in groundwater have been published,  independent
       and comparative  studies of passive samplers used  for  VOC  monitoring  in
       groundwater  are  scarce. Examples of reported performances (sampling and
       analysis) are compiled in Appendix table 7.

The precision results obtained with the passive samplers do not greatly differ
from the precision values obtained with reference sampling methods.  As the
precision data obtained with the reference methods will generally be accepted
for groundwater monitoring and control, the precision data obtained with the
passive samplers should also be considered acceptable.

4       Performance parameter definitions

The statement of regulatory and application based requirements in terms of the
analytical quality rather than the combined quality of analysis and sampling, as
relevant  for  passive samplers, makes the identification  of relevant  criteria
difficult for passive samplers.

Only a limited number of studies on the contributions of sampling and analysis,
respectively,  to the limit of detection, precision and trueness of groundwater
monitoring and  control have  been published.  Therefore, the regulatory and
application based requirements needs identified for analytical performance can
not be directly translated into the combined sampling and analysis performance
requirements relevant for passive samplers.

The discrepancies between requirements based upon different approaches when
comparing  Appendix table 2, Appendix table 3 and Appendix table 5,  further
hampers the identification of relevant criteria.

Therefore,  relevant performance parameters  for the  application are  set  in
Appendix table 9 based upon regulatory and  application based requirements
and state of the art performance.

In order to address the general  definition of performance parameters in terms of
analytical quality  only,  information  on this  using the  sampler should  be
obtained from the responsible laboratory for comparison, if possible.

In addition  to  the  straight  forward performance parameters  of limit  of
detection, precision, trueness and range  of application, the robustness shall  be
                               31

2      INTRODUCTION

       This joint test plan is the implementation of a test design de-
       veloped for verification of the performance of an environ-
       mental technology following the NOWATECH ETV method.

       The verification is a joint verification with the US EPA ETV
       scheme and the Advanced Monitoring Systems Centre, Bat-
       telle, see the verification protocol III for details on organiza-
       tion and implications. The compliance of the test with both
       scheme's requirements is ensured through a process docu-
       ment 111.

        TEST DESIGN

        The test design outlined in the test protocol is summarized in
        Table 1. The term "samples" is used for samples taken with
        the  Sorbisense sampler, whereas the term  "reference sam-
        ples" is used for water samples taken for reference analysis.
        Acronyms are explained in Appendix 1.

        If nothing else is stated below, the standard conditions for the
        stand pipe include mid range ionic strength (30-70 mS/m
        conductivity), a sampling period of 6 days and a sampling
        depth of 0.5 m (0.05 atm overpressure).

        In Table 1, labels are given for each experiment and for ex-
        periments with different levels, a new label is given for each
        level.

        Both the laboratory tests and the standpipe tests will be conducted in the DHI labora-
        tory buildings, H0rsholm, Denmark.

        The field tests will be carried out on contaminated groundwater sites in the Copenha-
        gen area.

3.1.2   Addresses
        See Table 2.

3.1.3   Descriptions
        See Table 2.

3.2    Tests
        The test program has been prepared to provide the information and to apply the ap-
        proaches presented for analytical quality control for water analysis (ISO 13530) /3/
        and for performance test of on-line  sensors/analysing equipment (ISO 15839) /4/. The
        field tests have been prepared to comply with the test requirements in the Cost Agree-
        ment (pre-standard) on verification of monitoring technologies for groundwater site
        characterization (CEN/WS 32:2008) 151.

        The test design,  as described in Table 1, includes three test scales: laboratory,  stand
        pipe and field.

        For chloroethene (vinyl chloride), the performance is only tested in a simplified labo-
        ratory design (direct application, best possible LoD, repeatability precision and true-
        ness) and in the field (worst realistic reproducibility precision and robustness) due to
        difficulties preparing, obtaining and handling chloroethene solutions.

-------
3.2.1   Test methods
        No standard methods exist for testing of passive samplers for groundwater monitoring.
        The test methods have accordingly been prepared for the purpose (see Appendix 3),
        with reference  to the Ground Water  Sampling Technologies Verification Test Plan
        prepared for the US EPA ETV program 161. Preparation of test solutions, reagents and
        chemicals are described in Appendix 3 as well. It should be noted that the methods in
        Appendix 3 are described at the detailed level of a work instruction for direct imple-
        mentation in the laboratory.

        For standpipe tests, groundwater, see Appendix 3.7, was used for preparing test solu-
        tions, and  for laboratory tests, (clean) water, also see Appendix 3.7, was used. All dilu-
        tions were prepared in water.

        For the laboratory and standpipe tests, custom-made stainless steel test devices have
        been being prepared, see below.

        For direct application laboratory tests,  a standard solution with chlorinated compounds
        only is applied to the samplers directly with a syringe, followed by equilibration and
        flushing with water using the sample dispenser, see Appendix 3.1 for method descrip-
        tion (no illustration).

        For the laboratory tests, a sample dispenser device, Figure 1, is designed  as a closed
        system that enables direct exposure of samplers to test solutions with known and sta-
        ble VOC  concentrations by conveying the test solution  from a closed container by
        gravity, see Appendix 3.2. The container is equipped with spiking port, sampling port
        and magnetic stirrer to maintain homogeneous conditions in the sample container.

-------
The standpipe test device, Figure 2, is designed with a closed container filled with test
solution where the sampling system with samplers can be suspended from the top, see
Appendix 3.3. Air from the sample reservoir is vented through an air hose. The con-
tainer is equipped with  sampling ports and mixing  is ensured through continuous
pumping from top to bottom.

For both the sample dispenser and the standpipe, the air entering the container to re-
place dispensed liquid is saturated with VOCs at the same concentration as in the con-
tainer, by using an air wash bottle.

The field sampling. Figure 3, is done by suspending the sampling systems with sam-
plers in the screened intervals in depth with the pump of established wells with con-

-------
       tinuous pumping (monitoring wells or pump-and-treat wells), see Appendix 3.4. Ref-
       erence samples are taken from the pumped streams (pump depth sampling strategy).

3.2.2
In cases, where the pump is deeper than the maximum sampling depth or the installa-
tions do not allow for positioning the sampler in pump depth, a position above is cho-
sen (above pump sampling strategy).  The sampler position is always within the
screened interval and within the same aquifer unit as the pump. In  such cases, a low
volume reference sampling pump is positioned  at the same depth as the sampler in-
take.

In all cases, a low purge sampling strategy is followed, allowing only for flushing of
sampling equipment.

       standard solutions by direct application. The term "samples" is used for samples taken
       with the Sorbisense sampler and analyzed accordingly.

       The term reference analyses covers analysis of standards and standard dilutions after a
       reference method in an accredited (ISO 17025) laboratory. The term reference samples
       covers sampling of water and analysis after a reference method in an accredited (ISO
       17025) laboratory.

       The analytical program shown  above includes 26 reference analyses of standard and
       stock solutions, as well as of dilutions. If the stability of the solutions and the analyti-
       cal precision proves satisfactory in the initial part of the program, the number of repli-
       cate reference analysis may be reduced.

       The water and the groundwater used in laboratory tests will be controlled for blanks,
       and the  groundwater further characterized for general groundwater parameters, see
       Appendices 2 and 3.7.
Includes also pretesting samples and analyses not in the above rows
                                    10

-------
        In addition to the number of test samples, samples controlling the test systems will be
        required as described in Appendix 3.5. The total number of samples for this purpose is
        18 reference samples. The samples will include test system blank samples.

REFERENCE ANALYSIS
        The reference analysis applies to an aliquot of the test solutions that will be submitted
        to an analytical laboratory for analysis.  These samples will verify the actual concen-
        trations of the test solutions and the results will be compared to the results of the prod-
        uct in this verification.

4.4     Analytical performance requirements

        The analytical performance requirements are given in Table 7.

        It should be noted that the uncertainties stated by the laboratory, Table 6, includes both
        the random error under reproducibility conditions (requirements set here for the preci-
        sion under repeatability conditions) and the systematic errors (requirements set here
        for the trueness).

        For MTBE, concern may be raised whether the laboratory will be able to satisfy  the
        required limit of detection.

6       QUALITY ASSURANCE

        The tests are performed under the quality management system of DHI which is ISO
        9001 compliant /I I/, but not certified. The DHI laboratories have ISO 17025 accredi-
        tations 111 and OECD GLP approvals 1121 for a range of tests and ISO 17025 for sam-
        pling of drinking water. As part of the ISO 17025 and GLP inspections, the procedures
        for general laboratory processes, quality assurance and documentation/archiving are
        assessed.

6.1     Test plan review

        The test plan will be subject to  internal review by the verification responsible from
        DHI WMC Verifications: senior chemist Christian Gran. Additionally, the test  plan
        will be subject to review by the Battelle Advanced Monitoring Center quality manager
        (Zachary Willenberg, respectively), as well as by the US EPA ETV AMS project  offi-
        cer, quality manager and ETV coordinator (John McKerna, Lauren Drees and Evelyn
        Hazell, respectively).

        External review of the test plan will be done by the expert group assigned to this veri-
        fication.

6.2     Performance control - reference analysis

        General chemistry, reference sample analyses and reference  analyses are done under
        the ISO 17025 accreditation of Eurofins.

        The performance of Eurofins for the reference analysis will be evaluated (performance
        evaluation audit) from laboratory quality control data for the relevant period  (precision
        under repeatability conditions, trueness). Data for the analytical quality control of the
        laboratory will include duplicate control samples  at two concentrations (acceptance
        within 100%±10%) in each series and at the least one blank sample per 5 samples. The
        data from participation in a proficiency test arranged by Analytical Products Inc  Sep-
                                    14

-------
        tember 2008 will be evaluated for the demonstrated precision and traceability for the
        compounds in question for relevant matrices.

        The detection limits and risks of false positives  of the laboratory are controlled by
        submitting blank samples and low concentration samples as described in the test pro-
        gram.

        The precision and trueness of the laboratory is further evaluated by analysis of stock,
        standard and spike  solutions used for the test (26 reference analyses). The reference
        analysis includes analysis of a standard with analytical certificate and of solutions pre-
        pared from pure chemicals at DHL

        The analytical reference performance control is summarized in Table 9, with reference
        to Appendix 3.6 and 3.7 for information  on water, standard solution  (purchased stan-
        dard with analytical certificate)  and VOC solutions (prepared by  DHI from pure
        chemicals).

6.3     Test system control

        The laboratory test design includes test solutions of known concentrations, traceable
        back to added chemicals of p.a.  quality or standards with analytical certificate, see
        Appendix 3.7 for specifications of purity etc.

        The known concentrations will be used to pre-test the test design, see Appendix 3.5.

        The water used for preparation of solutions will be controlled for contents of the target
        VOC as blanks by reference analysis.

        The stability of the test concentrations will be controlled continuously during the tests
        by taking and  analyzing reference samples distributed over the sampling periods, con-
        sidering the "true concentrations" based upon added amounts and the reference analy-
        ses.

        The control of the field test system is done using analysis of reference samples and
        field blank samples.

        The analytical reference performance control is  summarized in Table 10. Laboratory
        blanks/spiked  samples are water, in some cases with  ionic strength controlled by add-
        ing KC1, and the standpipe blanks/stand pipe samples are groundwater (matrix).

6.4     Data integrity check procedures

        All transfer of data from printed media to digital form and between digital media are
        checked by spot check of not less than 5% of the data (test or field responsible). If er-
        rors are found in a spot check, all data from the transfer are checked.

6.5     Test system audits

        Internal  audit from DHI following the GLP audit procedure by a trained auditor is
        done, see the verification protocol for details.

        The Battelle quality manager, Zachary Willenberg, will perform a technical systems
        audit (ISA) at least once during this verification and test. The purpose of this audit is
        to ensure that  the verification test is being performed in accordance with the AMS
        quality management plan /13/, this  test  plan, published reference methods  and  any
        methods used in the tests. In the ISA, the Battelle quality manager, or designee, may
        review the reference methods used, and compare actual test procedures to those speci-
        fied or referenced in this plan. In the TSA, the Battelle  quality manager will observe
        testing in progress, observe the  reference method sample preparation  and  analysis
        (when available),  inspect  documentation,  and review technology-specific record
        books. He will also check standard certifications and may confer with other Battelle
        staff. A TSA report will be prepared, including a statement of findings and the actions
        taken to  address  any  adverse findings. The  AMS  quality  manager  and  the
        NOWATECH WMC verification responsible will receive a copy of Battelle's TSA re-
        port. The TSA findings will be communicated to technical staff at the time of the audit
        and documented in a TSA report.

        The Battelle Quality Manager will perform an audit of data quality (ADQ). This will
        be a review of data acquisition and handling procedures and an audit of at least 10% of
        the data  acquired in the test and verification. The Battelle Quality Manager will trace
        the data  from initial acquisition, through reduction and statistical comparisons, to final
        reporting. All calculations performed on the data undergoing the audit will be checked.

        Reference analysis, VOC
Water samples are taken as 40 mL samples in autosampler vials filled completely from
the bottom and allow to overflow.

A precise volume of subsample is transferred from the sampler vial to the airsparger
via a sample loop and using helium as the pressure gas. The subsample is purged with
helium and the purged compounds trapped on a VOCARB 3000 adsorbent, followed
by thermal  desorption at 240°C and transfer of desorbed compounds to  the gas chro-
matograph (GC). GC separation is followed by selected ion monitoring and quantifica-
tion against external standard.

Selectivity is ensured by applying a maximum limit of 20% deviation of mass ratios
for the selected masses from reference run.

The equipment used is Tekmar Aquatek 70/Velocity XPT and Agilent 6890 GC/5973
or 5975 MS

Standard method references are EPA Method 624.2 191 and ISO 15680 /10/.

      The second planning step is to select the reference sampling strategy (pump depth or
      above pump) and to select the  sampling (0.5-5 mbgvt8) and reference sampling posi-
      tions. The pump depth sampling strategy applies sampling of the pumped stream. In
      cases where the pump is positioned deeper than the maximum sampler depth, a posi-
      tion above the pump is chosen,  the above pump strategy.

The reference sampling is done as follows, for the pump depth strategy:

a)  Mount sampling tube upon pump exit sampling tap
b)  Flush tap and tube 5-10 minutes with lowest flow filling the tube
c)  Fill sample containers from the bottom and allow to overflow 2-3 times
d)  Store and preserve samples as prescribed and send to the laboratory

The reference sampling is done as follows, for the above pump strategy:

a)  Ensure that well pump is running at routine yield
b)  Lower the pump into the well to the selected depth
c)  Purge with the lowest flow filling the tube for 5-10 minutes, max 5% of stationary
    pump yield
d)  Ensure stability (within 10%) of indicator parameters (pH, dissolved oxygen, con-
    ductivity)
e)  Fill sample containers from the bottom and allow to overflow 2-3 times ensuring
    no head space in the containers
e)  Store and preserve samples as prescribed and send to the laboratory

Reference sampling is done before, between and after each sampling, totally 4 times.

Field  blanks are prepared during the first reference sampling at each site.  Water is
transferred to sample bottles on site and the  samples at stored, transported and ana-
lyzed as reference samples.

Sampling is done using a Grundfos  MP1 pump  equipped with  10 mm  Teflon tubes,
leaving the tubes in each well. Indicator parameters (pH,  dissolved oxygen, conductiv-
ity, temperature) are measured in a flow through on-line cell.

Preparation of solutions for reference analysis

1       10 g/L VOC stock solution

Check of concentrations is done initially  and each time a subsample is taken out for
use.

Initial testing is done by filling a 1,5 mL capped vial with stock solution at -20 °C, us-
ing a low-flow pipette. Close vial. Produce triplicate vials in this way. Place each of
the 1 mL  capped vials in a larger capped vial. Store cold 1-5°C and dark for no more
than 3 days and transfer to laboratory with information of concentration range.

Check during use: after using part the stock solution in the vial for spiking, fill one 1,5
mL capped vials with the solution using a gas-tight syringe. Close the vial and place it
in a larger capped vial. Store cold 1-5°C and dark for no more than 3 days and transfer
to laboratory with information on concentration  range. Produce 2 more vials and keep
at -20 °C for possible future reference

2       0.1 g/L VOC solution

Check during use is done after using part the solution in the vial for spiking by  trans-
ferring 1 mL to a cap vial using a low-flow pipette. Close vial, shake well. Produce
triplicate vials in this way. Close the vials and place each in a larger capped vial. Store
cold 1-5°C and dark for no more than 3 days and transfer to  laboratory with  informa-
tion  of concentration range.

3       VOX Standard dilution

Check during use is done after using part the stock solution in the 6 mL vial with VOX
standard dilution for spiking. Fill three  1.5 mL capped vials with the solution using a
gas-tight syringe. Close the  vials and place them in a P&T vial. Store cold 1-5°C and
dark for no more than 3 days and transfer to laboratory with information of concentra-
tion  range

Managing, storing and shipping of samples/samplers

1       Managing samples

a)     Prior to each individual test, the sampling responsible (test technician or field
       responsible) labels the  correct type and number of sample vials, according to
       information in the test  plan and the data forms. For cap vials, only the labels
       are prepared, to avoid contamination.

b)     The test responsible checks the array  of labeled sample bottles and labels
       against the test plan and the data forms.

c)     After sampling, the sampling responsible takes a photo of the sample vials and
       sends the photo to the test responsible immediately.

d)     The sampling responsible stores the sample vials.

e)     The test responsible prepares a requisition for analysis, and sends it to the sam-
       pling responsible.

f)     The sampling responsible ships the samples, and making sure that they are sent
       within the maximum stated storage time.

g)     The sampling responsible informs the test responsible immediately when the
       samples have been sent.

h)     The sampling responsible keeps a copy  of the requisition with a note of the
       date of shipping.

2       Sample storing, reference samples

Water samples are taken in 40  mL P&T vials. Samples are stored cold 1-5°C and dark
for no more than 3 days prior to transfer to the laboratory.

3       Sample storing, samplers

Samplers are equipped  with protective caps in both  ends, placed in transportation
tubes and stored cold  1-5°C and dark for no more than 7 days prior to transfer to the
laboratory.

4       Sample shipping, reference samples

Water samples (P&T vials) are sent in  cooling boxes with cooling elements. Cap vials
with stock solution or stock dilution are placed individually into a P&T vial and may
be sent in a non-isolated package, with  one cooling element.
                             44

-------
5       Sample shipping, samplers




Samplers are packed in the transport tubes in a cardboard box at ambient temperature.

                 Data management
89

-------
In general, the data filing and archiving procedures of the DHI Quality Management
System will be followed.

All data recording and reporting is done in English, communication with Danish ex-
ternal and internal can be in Danish.

Data storage, transfer and control

The data to be compiled and stored are summarized in Table 8.

Analytical raw data will  be filed and archived according to the specifications of the
laboratories quality management systems under their ISO 17025 accreditation and are
thus not the concern of DHI staff.

Implementation

All e-mail communication is filed in the Outlook Exchange folders, see below struc-
ture.

The DHI person receiving an  e-mail (to field, not cc field) will file the e-mail.  The
DHI person sending an e-mail will use the "send and file" option and thereby ensure
prompt filing of all e-mails  sent. There is generally  no need to widespread cc when
sending e-mails, unless specific action or communication is required.

All paper communication is immediately filed in the binder established by GHE and
available in his office. The title page of the binder will resemble the folder structure at
dkstor, see below.

All recordings during testing in the laboratory or in the field are done in water proof
writing in hardback log-books with all  pages numbered page/total page number.  The
log books are filed with  the staff member using them until the testing is completed,
then with GHE and available at his office.

All data needed for the tests are recorded in the data sheets available from Appendix 5
of the Test Plan. The format can be Word tables, Excel worksheets or paper sheets as
decided by GHE  as test  responsible. The outline and format are mandatory and can
only be deviated from by  recording a deviation with justification, see the Test Plan.
                              90

-------
All calculations are done using Excel spreadsheets with names identifying the contents
and with headings and notes explaining the calculations.

All electronic files are stored at dkstor in the folder structure shown below. File names
are constructed to identify the contents. Subfolders can be established as found con-
venient, while again constructing folder names that identify the contents. When work-
ing away from network connection (offline), copies of files can be used on own PC,
but the server version is updated and the offline version deleted immediately after re-
turning to network connection.
