DISCHARGE MONITORING REPORT -
              QUALITY ASSURANCE (DMR-QA) STUDY 18
To Participating Chemistry Laboratories:

In March of 1998, the U.S. Environmental Protection Agency (USEPA) Office of Enforcement and
Compliance Assurance sent announcement letters to designated National Pollutant Discharge
Elimination System (NPDES) permittees, informing them that the USEPA and related state
agencies were continuing the NPDES Discharge Monitoring Report - Quality Assurance (DMR-
QA) studies.  These announcements contained the chemistry sample ordering form that you
subsequently submitted.  The purpose of these studies is to evaluate the analytical and reporting
ability of laboratories routinely performing chemistry and whole-effluent toxicity self-monitoring
analyses required in the designated NPDES permits.  For further information,  please refer to the
Chemistry Laboratory Requirements on page 1 inside.

Participation of NPDES permittees in this program, including proper analyses, reporting and
record retention, is mandatory based on the authority of Section 308(a) of the Clean Water Act.
The Agency's legal opinions, dated August 11, 1977 and January 9, 1989, reaffirm this authority.

If you have questions regarding the DMR-QA, please contact your state DMR-QA coordinator,
whose name address and telephone number are listed in the attached Chemistry Laboratory
Instructions.  These offices will play an important role in providing any subsequent study follow-
up action or guidance. Please include the complete name, address, USEPA Lab Code and
telephone number of your laboratory in all correspondence.

Thank you for your cooperation in this national program to improve the quality of NPDES self-
monitoring data.

                                            DMR-QA STUDY 18


                              CHEMISTRY LABORATORY REQUIREMENTS


1.      Some tests you normally perform for your permittee may not be included in the DMR-QA Study.  You are
       only required to perform analyses which have been requested by a permittee, provided they are included
       in the study.  Participating laboratories are required to perform only one of each type of analysis.
       regardless of the number of permittees that request it.  Review the analytes listed below to determine
       which analyses must be performed to satisfy the DMR-QA reporting requirements for each NPDES
       Permittee you support. To the extent feasible, analyze each DMR-QA sample the same way you would
       analyze a routine sample, i.e., usual analyst, usual analytical system, usual procedures, etc.

              Chemistry Analytes: aluminum, arsenic, cadmium, (total) chromium, cobalt, copper, iron, lead, manganese,'mercury, nickel, selenium,
              vanadium, zinc, pH, non-filterable residue (total suspended solids), oil and grease, ammonia nitrogen, nitrate nitrogen, orthophosphate,
              total Kjeldahl nitrogen, total phosphorus, 5-day biochemical oxygen demand, chemical oxygen demand, total organic carbon, 5-day
              carbonaceous biochemical oxygen demand, total cyanide, total phenolics (by the 4AAP method), and total residual chlorine.

2.      Ensure that you have received the appropriate study samples, reporting forms and instructions:

       1.      Replacement samples, reporting forms or instructions may be acquired by returning the completed
              Chemistry Sample / Information Replacement Form on the next page.  If you have analytical problems, the
              available concentrate volume in each ampul is usually sufficient to prepare a second sample1.

       2.      Unused samples may be handled in one of three ways:
                      Properly dispose of unused samples ensuring compliance with all federal, state and local
                      regulations governing waste management.  For more information regarding waste disposal, see the
                      Ampul Disposal Information on page 3.
                      Return unopened ampuls to the USEPA Contractor, ManTech Environmental, in accordance with
                      49 CFR 173.4, and using the return address on the sample shipment (4907 S. Alston Ave.,
                      Durham, NC 27713).
                      Retain samples for internal quality control. If stored at room temperature and out of direct light,
                      unopened samples are stable for at least one year. A complete list of "true'Ycalculated values may
                      be obtained after the results of the study have been distributed to permittees, which is expected to
                      occur in January, 1999. Your permittees may request a copy by contacting their Regional/State
                      Coordinator. Users of a Personal Computer w/modem may use the USEPA Office of Research
                      and Development Electronic Bulletin Board, modem number (513) 569-7700 or (513) 569-7610.  If
                      you need assistance with use of the Bulletin Board, call  (513) 569-7272 (do not call this number for
                      general information regarding PE Studies).

3.     Perform the analyses requested by your permittees; refer to the enclosed NPDES Chemistry Laboratory Data
       Report Form for a  convenient listing of the analyses available in the study.

4.     Report the results of your analyses and additional required information as specified on page 6, Completing
       the NPDES Chemistry Laboratory Data Report Form.

5.     Submit your reporting form to the requesting permittees in accordance with the instructions on page 7, Chemistry
       Laboratory Reporting  Procedure.

6.     After official evaluation of the study data by the USEPA, permittees will receive Performance Evaluation
       Reports and laboratories will be asked by the supported NPDES permittee(s) to explain reported values that
       were not within the study acceptance limits.  Permittees will then provide this explanation to the appropriate
       USEPA or State Agency.
               1Not applicable for the pH, demand and residue samples.

                                    TRACE METAL SAMPLE
       An ampul containing 5% nitric acid (v\v) is provided for preparation of the study sample.

                                    SAMPLE PREPARATION

       To prepare sample 1, fill a 1-L volumetric flask approximately 3/4 full with reagent water, pipette
10.0 mL (which contains 0.5 ml_ of concentrated nitric acid) of ampul 1 and 1.0 ml_ of trace-metal-grade
concentrated nitric acid into the flask, dilute to volume with reagent water, and mix well.  The resulting
samples should be analyzed for the following analytes at levels within the stated concentration ranges.

Notes:
       Samples, standards and reagent water blanks should all have the same acid matrix.  The solution
       resulting from the above dilution will contain 0.15% v/v nitric acid; additional or different acids may
       be used as appropriate for analytical procedures or to match standards.

       Mercury is present as a mixture of organic and inorganic forms. If a cold vapor method is
       used, an aliquot of the sample must be digested before analysis for mercury. However,
       digestion  of this sample for any other metal analysis in unnecessary.

       Chromium should be determined only as total chromium. When chromium is analyzed by direct
       air-acetylene AA, use of matrix modifiers or the less sensitive oxidizing flame may be necessary to
       control interfering ions.  Preferably, use a fuel-rich nitrous oxide-acetylene flame for best results.

       Some analytes may occur at concentrations that are too low for determination with simple direct AA
       and must be determined with ICP, furnace AA.^or AA after chelation extraction (where approved) to
       produce reportable results.

                                          pH SAMPLE


                                    SAMPLE PREPARATION

       To prepare the pH sample, pour the contents of the pH ampul directly into a <50-ml_ beaker; do
not dilute before determining pH.
NOTES:
       We acknowledge that, ideally: 1)  the strong memory effects of the calibrating buffers are removed
       by allowing the electrode(s) to soak in some of the sample prior to analysis, and 2)  laboratories
       should be able to use their entire routine analytical procedures in performance evaluation studies.
       However, there are practical limits to the amount of pH sample we can provide to you in our
       studies.

       Therefore, we propose that you soak your electrode(s) in distilled water to remove the memory
       effect of the calibration buffers before you analyze our pH sample as directed in the study
       instructions. We believe this adjustment to your normal procedure is reasonable, effective and
       should not adversely affect your chances of successful performance.

       If you cannot produce a valid pH measurement from your analytical system using a sample of 20
       mL (or 40 ml_ using the contents of an additional ampul which is available upon request),  your
       analytical system is beyond the scope of this study. For example, systems for continuous pH
       measurement may require a minimum sample size which is incompatible with the current study
       design. If your  pH system is incompatible with the study design, you should discuss this with your
       State DMR-QA Coordinator (see list at back of this set of instructions).

                                     NUTRIENT SAMPLES

       Two ampuls containing reagent-water solutions are provided to prepare two separate samples.
Sample 1 will contain inorganic nitrogen and phosphorus and may be analyzed for ammonia nitrogen,
nitrate nitrogen, and orthophosphate phosphorus. Sample 2 will contain organically-bound forms and may
be analyzed for total Kjeldahl nitrogen and total phosphorus. When prepared according to instructions,
samples will contain <50 mg/L of each nutrient.

                                   SAMPLE PREPARATION

       To prepare sample 1, fill a 1-L volumetric flask approximately 3/4 full with ammonia-free, reagent
water, pipette 10.0 ml_ of ampul 1 solution into the flask, dilute to volume with reagent water, and mix well.
To prepare sample 2, repeat the procedure with ampul 2.
NOTES:
       Solutions in ampuls were preserved by autoclaving the sealed ampuls. Because this preservative
       treatment is not effective after ampuls are opened, open ampuls just before analysis.

       If a solution is not to be analyzed within two days after preparation, preserve a sample aliquot with
       0.2 mL of concentrated sulfuric acid per 100 mL of sample (pH <2) and store at 4ฐC until just
       before analysis. Analyze the preserved sample as soon as possible within the maximum 28-day
       holding time.
       Report results as milligrams per liter with three figures.

                                     DEMAND SAMPLE

       One ampul containing reagent-water solution is provided to prepare one sample. The sample may
be analyzed to determine 5-day biochemical oxygen demand (BOD), 5-day carbonaceous BOD (CBOD),
chemical oxygen demand (COD), and total organic carbon (TOG).

                                   SAMPLE PREPARATION

       To prepare the sample, fill a 1-L volumetric flask approximately 3/4 full with reagent water, pipette
20.0 mL from the ampul into the flask, dilute to volume with reagent water, and mix well. The sample is
ready for analysis to determine 5-day BOD, 5-day CBOD, COD and TOG. Each measured value should be
<300 mg/L.

NOTES:
•      The ampul contains about 21 mL of solution; if clean dry pipettes are used, this is sufficient to
       prepare the sample. More ampuls may be requested if both 5-day BOD and 5-day CBOD are to be
       determined. If an additional sample is needed, complete the "Request for Sample Replacement"
       sheet attached to the cover memorandum and submit as directed.

•      The solution in this ampul was preserved by autoclaving the sealed ampul. Because this preserva-
       tive treatment is not effective after the ampul is opened, open the ampul just before analysis.

•      Begin the BOD and/or CBOD as soon as possible after sample preparation. If cooled to 4ฐC, the
       maximum holding time for these analyses is 48 hours.  If COD and/or TOG cannot be analyzed
       within your usual holding time after sample preparation, an aliquot should be preserved (pH <2)
       using 0.2 mL of concentrated sulfuric acid per 100 mL (or an  equivalent amount of another acid
       which is compatible with your chosen methods). This acid preserved portion should be stored at
       4ฐC and analyzed as soon as possible within the 28-day maximum holding time.

•      5-day BOD and 5-day CBOD: For proper oxygen depletion, the sample should be tested in a
       dilution  series such as 4%, 8%, and 16%.  Use a natural surface water, diluted domestic sewage,
       or commercially available seeds for seeded dilution water and avoid entrainment of air. For a 5-
       day CBOD, the use of a nitrifying inhibitor is recommended.

•      Be sure to determine the "blank" BOD of your seeded dilution water so that the proper seed
       correction can  be made (See STANDARD METHODS, 17th edition, Page 5-6).

•      Report results  as milligrams per liter with three figures.

                                      CYANIDE SAMPLE

       One ampul containing a reagent-water solution is provided to prepare one sample.

                                   SAMPLE PREPARATION

To prepare the sample, fill a 1-L volumetric flask approximately 3/4 full with reagent water and add 1 mL of
1N NaOH. Pipette 10.0 ml of the solution from the ampul into the flask, dilute to volume with reagent
water, and mix well.

NOTES:

•      CAUTION: The sample should be analyzed as soon as possible after opening and diluting.

•      The cyanide concentration will be <2 mg/L.

•      To prevent a concentration change, the ampul and, even more importantly, the prepared sample
       should not be exposed to sunlight or other ultraviolet light any longer than necessary. Therefore,
       perform the analysis immediately after sample preparation.

•      The specified addition of 1 mL of 1 normal sodium hydroxide is only a recommended minimum to
       prevent the loss of cyanide. If another amount, or even another base (such as KOH) is part of the
       analyst's "normal routine", it is his/her option to change the recommendation.

•      Since all the cyanide is present in soluble forms, filtration of the sample is not necessary, however,
       the sample will require distillation.

•      The presence of a precipitate in the ampul is not a problem, unless it is blue in color.

•      Report results as milligrams per liter with three figures.

               NON-FILTERABLE RESIDUE (TOTAL SUSPENDED SOLIDS) SAMPLE

       One vial containing homogeneously mixed solids is provided to prepare one sample.

                                    SAMPLE PREPARATION

       To prepare the sample, fill a 1-L volumetric flask about 3/4 full with reagent water.  Soon after
opening and without drying, weigh 500 mg of solids from the vial and quantitatively transfer to the volumetric
flask using a glass funnel and wash bottle filled with reagent water. After rinsing the glass funnel
thoroughly and removing it, dilute flask contents to volume with additional reagent water (see notes) and
mix by inverting the flask 10 times. Let the sample flask stand for 10 min and invert again 10 times.
Immediately after the second set of inversions, rapidly measure a 500-mL aliquot into a graduated cylinder
by repetitively mixing and pouring so as not to allow solids to settle in the flask before the transfer is
complete. Filter this 500-mL aliquot and determine the non-filterable residue (total suspended solids)
according to your chosen routine method.
NOTES:
        Do not dry the vial contents prior to weighing the 500 mg of mixed solids. Weigh the solids as
        received without any preparatory action.

        If a significant portion of the weighed (500 mg) solids fails to disperse evenly and stubbornly floats
        on the surface, add a few drops of diluted detergent to the partially filled sample preparation flask.
        For example, dissolve approximately 10 mL of detergent in 100 mL of reagent water and mix.
        Then add 2 drops of this diluted detergent to the sample preparation flask, mix, observe, and
        repeat (if necessary) the 2 drop additions until the suspended sample appears to be dispersed
        evenly.  Choose a detergent which will rinse clean from the Gooch crucible and filter pad without
        leaving a measurable residue requiring a blank subtraction.  Possible conveniently accessible
        choices might be Triton-X-100, or any house-hold liquid dish-washing detergent void of insoluble
        ingredients.  If your detergent fails to disperse the solids evenly and it was not Triton-X-100, try
        Triton-X-100. If all else fails, request a new ampul.

        CAUTION: The analysis should be performed soon after the 500 mL aliquot is obtained.

        Report results as milligrams per liter with three figures.
                                     Ampuls contain NaCI.

       One ampul containing a solution of oil and grease in n-propanol and glycerol is provided to prepare
one sample.

                                   SAMPLE PREPARATION

       To prepare the sample, add 994 ml_ of reagent water and 5 mL of 1:1 hydrochloric acid into a 2-L
separatory funnel and mix. Pipette 1.0 mL of the ampul solution into the separatory funnel and mix well.
Analyze the sample using whatever analytical  method you most often use on routine samples. Note that
data produced using hexane for extraction must be reported in a different place on the report form than
data produced using Freon for extraction.
NOTES:
       To avoid a concentration change, the sample must be analyzed soon after the ampul has been
       opened.

       The sample should be analyzed with an approved gravimetric method, because it is not suitable for
       an infrared method.

       For calculations, assume that initial sample volume was 1000 mL.

       Report results as milligrams per liter with three figures.
                         Ampuls contain n-propanol (flammable liquid)

                                TOTAL PHENOLICS SAMPLE

       One ampul containing a reagent-water solution is provided to prepare one sample.

                                   SAMPLE PREPARATION

       To prepare the sample, fill a 1-L volumetric flask approximately 3/4 full with reagent water. Pipette
10.0 mL from the ampul into the flask, dilute to volume with reagent water, and mix well. Analyze the
sample using a 4AAP method ONLY.

Notes:

•      In each sample, the resulting total phenolic concentration will be <6 mg/L.

•      The solution in the ampul was preserved by autoclaving the sealed ampul.  Because this
       preservative treatment is not effective after the ampul is opened, open the ampul just before analy-
       sis.

ซ      Do not report phenolic results determined with GC/MS, because GC/MS data are not equivalent to
       data obtained with the 4AAP methods.

•      Report results as milligrams per liter with three figures.
                       END OF INSTRUCTIONS FOR TOTAL PHENOLICS

                            TOTAL RESIDUAL CHLORINE SAMPLE

       One ampul containing a reagent-water solution is provided to prepare one sample.

                                   SAMPLE PREPARATION

To prepare the sample, fill a 1-L volumetric flask approximately 3/4 full with chlorine-free, reagent water.
Pipette 10.0 mL from the ampul into the volumetric flask, dilute to volume with reagent water, and mix well.

NOTES:

•      In this sample, the resulting concentration of total residual chlorine will be <6 mg/L.

•      To prevent a concentration change, the ampul and prepared sample should not be exposed to
       sunlight or other strong light or agitation any longer than necessary.  Therefore, perform the
       analysis immediately after sample preparation.

•      Report results as milligrams per liter with three figures.
