      This  is  the last WS study to be provided by the USEPA;  consult your state or
regional WS  coordinator for direction regarding future WS  studies.

      Enclosed are the WS041 samples requested for you by  your  USEPA or state
coordinator.   Analyze all appropriate samples using your routine  analytical methods.
Follow carefully the instructions  for each type of sample  and the General -Instructions
for Reporting  Results.   Results are to be reported in terms of  single analyses on the
diluted, full-volume samples.   Note especially that if you wish to be evaluated for the
analyte "Total Trihalomethanes," you must now sum the individual  trihalomethanes and
report your  total in the space indicated on the data reporting  form.   Analytes not  '
currently regulated  by the Office  of Ground Water and Drinking  Water (OGWDW)  are not
intended for official certification at this time.

      Analyses for this study must be completed and received  in Cincinnati no later
than August  10,  1998.   Results received after this date may not be evaluated by NERL.
PLEASE NOTE  POLICY FOR RETURNING STUDY RESULTS.  MAKE AS MANY COPIES OF THE REPORT FORM
AS YOU NEED, ONE FOR YOUR RECORDS,  ONE FOR ANY COORDINATOR WITH AN INTEREST IN YOUR
PERFORMANCE  (SEE ATTACHED LIST)* AND RETURN THE ORIGINAL TO:

      this data for  later follow-up on your performance, e.g.,  certification,  etc.   It
      is your  responsibility  to provide this information to them.   Any response for
      corrective actions  should be directed to your certification officers,  NOT NERL.

      If there are technical questions or problems, contact your state or      :
regional coordinator (see attached list) .  To order replacement samples, do not
contact your state or regional coordinator, but submit the attached request form
as directed.

      As usual with recent WS studies, WS041 includes samples containing
regulated and unregulated analytes.  Generally, analyses for the regulated
analytes will be considered for official drinking water laboratory certification,
while analyses for the unregulated analytes are only for mutual information.
Note that barium is not present in dissolved form in the WS041 trace metals
ampul.  Please contact the coordinator of each certification office you are
involved with to verify their policy regarding the necessity of you analyzing for
any specific analyte.  Data reported for the low-level turbidity samples will not
appear in the individual laboratory PE reports, but will be summarized in a
separate memorandum to be available upon your request from regional and state
coordinators after the study.


      As a participant in WS041-, you are herein provided sample concentrates for
one or more of the following nine  sets:

 OP THE SET OF INDIVIDUAL  SAMPLE PREPARATION INSTRUCTIONS  FOR ALL CHEMICALS
 PRESENT  AT CONCENTRATIONS COVERED UNDER THE HAZARD COMMUNICATION STANDARD OF THE
 OCCUPATIONAL SAFETY AND HEALTH  ACT.

     Three VOC samples were prepared for this study.  VOC Sample 1 contains all
 twenty-one regulated VOCs:  trichloroethylene, carbon.tetrachloride,. 1,1,1-  *
 trichloroethane,   1, 2-dichloroethane, vinyl  chloride, benzene,  1,1-
 dichloroethylene, dichloromethane, 1,1,2-trichloroethane, 1,4-dichlorobenzene,
 1,2-dichlorobenzene, cis-1,2-dichloroethylene, trans-1,2-dichloroethylene,  1,2-
 dichloropropane,   ethylbenzene,  chlorobenzene, styrene, tetrachloroethylene,
 toluene, 1,2,4-trichlorobenzene and xylene  (total).  VOC  Sample  2  contains  some
 of the unregulated VOCs listed  on page 25710 of the Federal  Register of July 8,
 1987.  This  second sample is a  greater challenge since  the analyst is not
 informed of  the number of compounds present, their identities  or concentrations.
 If you report any results for VOC Sample 2, you must report  results  for every VOC
that is present in that sample.  VOC Sample 3 contains  the regulated VOC's  EDB
and DBCP, and must be analyzed by Method 504.1 OR 551.  Report just  the EDB and
the DBCP found in this ampul.

-------
      Data for unregulated analytes and the low-level turbidity sample are needed to
support the development of proposed federal regulations.   These analytes are not
intended for immediate certification,  but may be considered as a basis for
certification when an analyte becomes regulated.  Check with your state agency
regarding their policy on certification for these analytes.

      Methods for all analytes are listed in the General Instructions for Reporting
Results included in these instructions.  REMEMBER1   Analyses for certification MUST;be
done by an officially approved method.  If copies of USEPA methods are needed,  complete
the appropriate order form (see enclosures) and mail as indicated.  USE ONLY THE ORDER
FORM ENCLOSED WITH THIS MEMORANDUM.  If there are any questions about the approval
status of a method, contact your USEPA or state coordinator before using the method for
any official analyses.

      Please note enclosed addendum sheet for methods in "Methods for Determination or
Organic Compounds in Drinking Water - Supplement II."

      A standardized set of instructions covering all analytes is enclosed.  It is the
analyst's responsibility to separate out the appropriate sample concentrates and
instructions for the analytes to be tested.  Unneeded sample concentrates should be
disposed of properly  (see enclosed "Ampul Disposal Information"), or reserved for later
use as internal quality control samples.  For those interested in use of the
concentrates as quality control samples, a list of true values and limits may be
obtained from the technical contact listed previously or  (through a communicating
personal computer  [PC]) from the USEPA Office of Research  and Development Electronic
Bulletin Board System  after study results have been sent to participants.  See
attachment from Randy  Revetta regarding access to this system.

      Quality Assurance Coordinators will be notified of any schedule changes.  This
information will also  be available on the ORD Bulletin Board.

      Generally, a  separate sample is prepared  from each concentrate as directed in the
specific instructions  for each group.  Report results for  as many of the analytes as
your  laboratory wishes evaluation or as directed by the responsible USEPA or state
official.

      Our policy is to carry all study limits to three figures.   Since  there are
variable effects of rounding-off on  the acceptability of  results  if  reported  to only
two figures, we recommend that results be  reported to three  figures whenever possible.

      We do not require copies of  the  background information that relates  to the
analytical runs from which your study data were developed.  However, you  should retain
this  information,  for  example, results  of  related QA/QC activities, records of related
analytical output,  etc.,  in your files  for use  during your own follow-up  investigation
on the cause of any unacceptable data.

                                     ADDENDUM


     The following sections will replace Section 14.2 and Section 15 in all
methods published in the EPA/6--/R-92/129 methods manual entitled, "Methods for
the Determination of Organic Compounds in Drinking Water - Supplement II."

14.2 For information about pollution prevention that may be applicable to
     laboratory operations, consult "Less is Better:  Laboratory Chemical
     Management for Waste Reduction" available from the American Chemical
     Society's Department of Government Relations and Science Policy, 1155 ISth
     Street N.W.,  Washington,  DC  20036.

15.  MANAGEMENT

15.1 It is the laboratory's responsibility to comply with all federal,  state,  and
     local regulations governing the 'waste management,  particularly the hazardous
     waste identification rules and land disposal restrictions.  It is also the
     laboratory's responsibility to protect the air,  water,  and land by
     minimizing and controlling all releases from fume hoods and bench
     operations.  Compliance is also required with any sewage discharge permits
     and regulations.   For further information on waste management,  consult "The
     Waste Management Manual for Laboratory Personnel," also available from the
     American Chemical Society at the address in Section 14.2
