 1.5 Analysts and Operators in Training
 Data produced by analysts and instrument operators while
:'in the process,of obtaining the required training  or
 experience are acceptable when reviewed and validated by
 a fully qualified analyst or the laboratory supervisor.

 1.6 Waiver of Academic Training Requirement
 The certification officer may waive the need for specified
 'academic training, on  a case-by-case basis,  for highly
 experienced analysts.

 2.  Laboratory Facilities
 The laboratory facilities should be clean, have temperature
 .and humidity adequately controlled in the instrument areas
 and have adequate lighting at the bench top. It is important
 for the laboratory to have provisions for the proper storage
 and disposal of chemical  wastes. Exhaust hoods are
 required for preparation,  extraction  and  analysis where
 applicable.

 It. is recommended that a minimum of 150 to 200 square
 feet/laboratory person be available. The laboratory should
 contain  at least 15 linear feet of usable bench  space  per
 analyst. Workbench space should be convenient to sink,
                                                     15
                                                Change 2

-------
  water, gas, vacuum and electrical sources free of surges. It
  is recommended that the organic and inorganic facilities be
  separate rooms. The analytical and sample storage area is
  to be Isolated from all potential sources of contamination.

  3.  Laboratory Equipment and
  Instrumentation
  The laboratory is only required to have those instruments
  that are needed to perform the approved methods for which
  certification has been requested. Those  instruments must
  meet the specifications in the checklist entitled "Required
  Equipment and Instruments for Inorganic and Organic
  Contaminants".

  4.   General Laboratory Practices
  4.1  General

       4.1.1  Chemicals/reagents: "Analytical reagent
       grade" (AR) chemicals or  better must be used for
       analyses.  Consult Standard Methods for the
       Examination of Water and Wastewater" 17th edition,
       part 1070C, pages 1 -42 through 1 -45for more detailed
       Information on reagent grades. Individual analytical
       methods in the approved reference may specify
       additional requirements for the reagents to be used.

      4.1.2  Laboratory  safety: While  specific safety
      criteria are not an aspect of laboratory certification,
      laboratory personnel should  apply  general and
      customary  safety practices as  a part of good
      laboratory procedure. Each  laboratory  is strongly
      encouraged  to have a safety plan  as part of their
      standard  operating  procedure (see  OSHA
      requirements). Where safety practices are included in
      an approved method, they must be strictly followed.

 4.2 Inorganic Contaminants

      4.2.1  Reagent water: The laboratory is to have a
      source of reagent water having a sensitivity value of
      at least 0.5 megohms (less than 2.0 micromhos/cm)
      at 25C. High quality  water  meeting  such
      specifications may be  purchased from commercial
      suppliers. Quality of reagent water is best maintained
      by sealing from the atmosphere. Quality checks to
      meet specifications  above should be made and
      documented at planned intervals based on use. This
      planned interval should not exceed one month.

      4.2.2  Glassware preparation:  Glassware should
      be washed  in  a  warm detergent solution  and
     thoroughly rinsed first with tap water and then with
      reagent water. This cleaning procedure is sufficient for
     general  analytical needs, but  the individual
     procedures must be referred to for precautions to be
     taken  against contamination of glassware. It  is
     advantageous to maintain separate sets of suitably
     prepared glassware for the nitrate, mercury, and lead
     procedures due to the potential for contamination from
     the laboratory environment.
     4.3  Organic Contaminants

          4.3.1   Reagent water: Reagent water for organic
          analysis is to be free of interferences for the analytes
          being measured.  It may be necessary to treat water
          with activated carbon to eliminate all interferences.

          4.3.2   Glassware preparation: Glassware   and
          sample bottles should be washed in a  detergent
          solution and thoroughly rinsed first in tap water and
          then in reagent water. Glassware should have a final
          organic solvent rinse or must be baked at 400C for
          30 minutes and then dried or cooled in an area free of
          organic contamination. Glassware should be covered
          with organic-free aluminum foil during storage. Bottles
          and cap liners, used for collection of samples for
          determination  of volatile organic chemicals (VOCs),
          should be dried at 105C for 1  hr, sealed, and stored
          in an area free of volatile organics.

     5.   Analytical Methodology
     5.1  General
     A list of approved methodology for inorganic and organic
     contaminants can be found in  Tables IV-1 and IV-2,
     respectively. In  general, all procedural steps  in  these
     methods  are considered requirements.  Other  methods
     cannot be used unless approval has been approved by the
     Agency. Contact the appropriate certifying authority for an
     alternate test procedure application. Application for the use
     of an alternate method may require acceptable comparability
     data.  Prepackaged  test kits  other than the U.S.
     EPA-approved DPD and the FACTS Colorimetric Test Kits
     are not approved for  use. Recommended methods for
     inorganic contaminants that do  not require the use of an
     approved method are listed in Table IV-3.

         5.1.1  If a'drinking water sample contains less than 1
         nephelometric  turbidity unit (NTU) and is properly
         preserved,  the sample may be  analyzed  directly
         (without digestion) when using one of the following
         total element  techniques: graphite furnace -AA,
         ICP/AES,  ICP/MS,  or direct flame aspiration AA,
         Turbidity should be measured  on the  preserved
         sample just prior to when the metal analyses are
         initiated. For gaseous hydride  determination of
         arsenic, antimony, or selenium, or  for the
         determination of mercury by the cold vaportechnique,
         the proper digestion technique must be followed to
         ensure that the element is in the proper chemical state
         for analysis.

    5.2  Non-certified analysis
    Measurements for pH,  temperature,  turbidity,  residual
    disinfectant, calcium, orthophosphate, silica, alkalinity, and
    conductivity need not be made in certified laboratories, but
    may be  made by any person acceptable to the  state.
    However, approved methodology must be used (Table IV-1).
    The state should institute a quality assurance program to
    assure validity of data from these measurements.

-------
     5.2.1  Sealed liquid turbidity standards purchased
     from the instrument manufacturer must be calibrated
     against properly prepared  and diluted formazin  or
     styrene divinylbenzene  polymer standards at least
     every 4 months in order to  monitor for any eventual
     deterioration. This calibration is to be documented.
     The standards are to be replaced when they do not
     fall within 15% of the assigned value of the standard.
     Solid turbidity standards composed of plastic, glass,
     or other materials are not reliable  and should not be
     used.   ,

     5.2.2  If visual  comparison devices such as color
     wheels or sealed ampules  are used for determining
     free chlorine residual, the standards incorporated into
     such devices should be calibrated at least every six
     months. These calibrations are to be documented.
     Directions for preparing temporary and permanent
     type visual standards can be  found in Method
     4500-Cl-G, Standard Methods, 17th ed.,  1989.  By
     comparing standards and plotting such a comparison
     on graph paper, a corrective factor can be derived and
    , appliedtofutureresultsobtainedonthenowcalibrated
     apparatus.  ,

6.  Sample Collection, Handling, and
Preservation
The manner in which samples are collected and handled is
critical for obtaining valid data. It is essential that a written
sampling protocol with specific  sampling  instructions be
available to sample collectors and for inspection by  the
certification officer (see Appendix A, Chain-of-Custody).

6.1.  Rejection of Samples
The laboratory is to reject any sample taken for compliance
purposes not meeting the criteria in 6.2 through 6.6 below
and notify the system/individual requesting the analyses.

6.2.  Sample Containers and Preservation
The type of sample container and the required preservative
for each inorganic and organic chemical contaminant are
listed in Table IV-4 and Table IV-5, respectively.

6.3.  Maximum Holding Times
Samples must be analyzed  within the maximum holding
times listed in Tables IV-4 and IV-5.

6.4.   Sample Collection and Transport
When the laboratory has responsibility forsample collection,
handling,  and preservation, there  needs to be strict
adherence  to correct sampling procedures, complete
identification  of  the sample, and prompt transfer of the
sample to the laboratory.

 6.5  Sample Collector
The collector should be trained in sampling procedures and
 approved by the State regulatory authority or its delegated
 representative.

 6.6  Sample Report Form
 The sample report form should contain the location, date and
 time of collection, collector's name, preservative added,
sample  type, and any special remarks concerning the
sample. Indelible ink should be used.


7.   Quality Assurance
7.1  General Requirements:

     7.1.1  All quality control information is to be available
     for inspection by the certification officer.

     7.1.2  A  manual  of  analytical methods and the
     laboratory's QA plan are also to be available to the
     analysts (see Chapter Ill's discussion of the QA Plan).

     7.1.3  Class S Weights or better should be available
     to make periodic checks on  balances. A record of
     these checks is to be available for inspection. The
     specific checks and their frequency are to be as
     prescribed in  the  laboratory's QA  plan and the
     laboratory's operations manual, if appropriate. This
     frequency should not exceed 6 months.

     7.1.4 Color standards, or their equivalent such as
     built-in internal standards, are to be available to verify
     wavelength settings on spectrophotometers. A record
      of these checks should be available for  inspection.
     The specific checks and their frequency are to be as
      prescribed in the laboratory's QA plan and the
      laboratory's operations manual, if appropriate. The
      frequency of these checks  should  not exceed  6
      months.

 7.2 Analytical Quality Control
 The following are required for each analyte for which  a
 laboratory is certified:

      7.2.1  The  laboratory must analyze  PE samples
      (when available) at least annually.

      7.2.2  At least once each quarter, the laboratory
      should analyze a QC sample (EPA certified QC
      sample orequivalent). If errors exceed limits specified,
      corrective action is to be taken and documented, and
      a follow-up quality control standard analyzed as soon
      as  possible to demonstrate  the problem has been
      corrected.

      7.2.3  At the beginning of each day that samples are
      to be analyzed, a standard curve composed of at least
      a reagent  blank and  three standards covering the
      sample concentration range  are to be prepared.
      These standards should be  from  a source different
      than the quality control standard used for 7.2.2.

      7.2.4  Calibration for  some  methods  is  so
      time-consuming that 7.2.3 is impractical. For these
       methods,  the standard curve  is  to  be  initially
       developed as specified In 7.2.3. Thereafter, at the
       beginning of each day  on  which analyses are
       performed, this curve is to be verified by analysis of at
       least a reagent blank and one standard in the expected
       concentration range of the samples analyzed that day.
       All checks should be within the control limits specified
                                                      17
                                            Change 2

-------
        In 7.2.7 or the system recalibrated as specified  in
        7.2.3.

        7.2.5  If the reagent blank specified in 7.2.3 (or
        paragraph 7.2.4)  is not carried through the full
        analytical procedure, then some other blank (at least
        one per day) is to be carried through the entire
        analytical  procedure. Results from reagent blanks
        should not exceed the laboratory's method detection
        limit (MDL); see paragraph 7.2.8.

       7.2.6  The laboratory should add a known spike to a
        minimum of 10% of the routine samples (except when
       the method specifies a different  percentage, i.e.,
       furnace methods) to determine if the entire analytical
       system Is In control. The spike concentration should
       not be substantially less than  the  background
       concentration of the sample selected for spiking.
       These checks should be evenly spaced and one check
       should be at the end of the day's analyses. Overtime,
       samples from all routine sample sources should be
       spiked. If any of these checks are not within the control
       limits specified in paragraph 7.2.7, a standard should
       be analyzed  to determine  if the "out of  control"
       condition was due to  sample matrix or system
       operation. This standard is to be analyzed through the
       complete analytical system. Corrective action is to be
       taken In accordance with the laboratory's QA plan.

       7.2.7  Until sufficient data  are available from the
       laboratory, usually a minimum of 15 to 25 test results
       on a specific  analysis, the laboratory is to use the
       control limits, if available, developed from the mean
       (X) and the standard deviation  (S) relationships in
       Table IV-6. This Table was derived from EPA's PE
       sample data.  After inserting  the  analytical
       concentration (c), including background concentration
       (B) wherever  appropriate, into  the proper pair of
       relationships, compute control limits for standards X
       3(S) and for spike recoveries (X-B)  3(S). As
       sufficient data becomes available, the laboratory
      should develop traditional QC chart criteria for the
      various QC checks specified above (see Chapter 6 of
      the Handbook for Analytical  QA in  Water and
      Wastewater Laboratories,  EPA-600/4-79-019,  or
      similar QC  reference texts for further information).
      Since percent  recovery may  not be a constant, the
      percent recovery data may have to be separated into
      concentration  Intervals  before control limits are
           calculated for each interval. If any of these control
           limits are tighter than the matching control limits in
           Table IV-6, the laboratory shall use the tighter criteria.
           Otherwise, control limits in Table IV-6 are required.
           The laboratory should continue to calculate traditional
           control  limits for each analyte as additional results
           become available.

           7.2.8  It is further recommended that the  laboratory
           calculate the MDL at least annually in accordance with
           the procedure given in 40 CFR Part 136, Appendix B.
           This procedure is available from EPA, Environmental
           Monitoring Systems Laboratory, 26 W. Martin Luther
           King Drive, Cincinnati, Ohio, 45268.


     8.   Records and Data Reporting
     8.1  Laboratory Records.
     Records  of chemical  analyses are to be  kept by the
     laboratory for  a minimum of 3 years.  This includes all raw
     data, calculations, and quality control data. These data files
     may be either manual or computer based. Hard copy should
     be  developed  as soon as  possible  and stored for
     recordkeeping purposes. The following information should
     be available as a sample data report or summary record:

          8.1.1  Date, place,  time of sampling,  preservative
          added, and name of person who collected the sample.

          8.1.2  Identification  of sample as to whether it is a
          routine distribution system sample, check sample, raw
          or finished water sample, or other special purpose
          sample.

          8.1.3  Date of receipt of sample and date of analysis.

          8.1.4  Laboratory  and  persons responsible for
          performing analysis.

          8.1.5  Analytical technique/method used, and quality
          control data.

          8.1.6  Results of analysis.


    9.   Action Response to Laboratory Results
    When action  response  is a  designated  laboratory
    responsibility, the laboratory must notify the proper authority
    of noncompliance sample results and request resampling
    from the same sampling point immediately.

   The holding time for Heptachlor under this method is 7 days.
   Samples that have been preserved with HgCte may be disposed of in at least two ways: as a hazardous waste, or by passing over an
   absorbent column (i.e., Alumina, activated with carbon, etc.) for mercury absorption, with the effluent analyzed periodically for break-
   through. The absorbent would then be disposed of as a hazardous waste. Other techniques may be applicable.
