Table IC notes:
\1\ All parameters are expressed in micrograms per liter (µg/L) except for Method 1613B in which the parameters are expressed in picograms per
liter (pg/L).
\2\ The full text of Methods 601-613, 624, 625, 1624B, and 1625B, are given at Appendix A, ``Test Procedures for Analysis of Organic Pollutants,'' of
this Part 136. The full text of Method 1613B is incorporated by reference into this Part 136 and is available from the National Technical Information
Services as stock number PB95-104774. The standardized test procedure to be used to determine the method detection limit (MDL) for these test
procedures is given at Appendix B, ``Definition and Procedure for the Determination of the Method Detection Limit,'' of this Part 136.
\3\ ``Methods for Benzidine: Chlorinated Organic Compounds, Pentachlorophenol and Pesticides in Water and Wastewater,'' U.S. Environmental Protection
Agency, September, 1978.
\4\ Method 624 may be extended to screen samples for Acrolein and Acrylonitrile. However, when they are known to be present, the preferred method for
these two compounds is Method 603 or Method 1624B.
\5\ Method 625 may be extended to include benzidine, hexachlorocyclopentadiene, N-nitrosodimethylamine, and N-nitrosodiphenylamine. However, when they
are known to be present, Methods 605, 607, and 612, or Method 1625B, are preferred methods for these compounds.
\6\ ``Selected Analytical Methods Approved and Cited by the United States Environmental Protection Agency,'' Supplement to the Fifteenth Edition of
Standard Methods for the Examination of Water and Wastewater (1981).
\7\ Each Analyst must make an initial, one-time demonstration of their ability to generate acceptable precision and accuracy with Methods 601-603, 624,
625, 1624B, and 1625B (See Appendix A of this Part 136) in accordance with procedures each in Section 8.2 of each of these Methods. Additionally, each
laboratory, on an on-going basis must spike and analyze 10% (5% for Methods 624 and 625 and 100% for methods 1624B and 1625B) of all samples to
monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these Methods. When the recovery of any parameter falls
outside the warning limits, the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate
regulatory compliance.
Note: These warning limits are promulgated as an ``interim final action with a request for comments.''

\1\ Pesticides are listed in this table by common name for the convenience of the reader. Additional pesticides may be found under Table 1C, where
entries are listed by chemical name.
\2\ The full text of Methods 608 and 625 are given at Appendix A. ``Test Procedures for Analysis of Organic Pollutants,'' of this Part 136. The
standardized test procedure to be used to determine the method detection limit (MDL) for these test procedures is given at Appendix B, ``Definition
and Procedure for the Determination of the Method Detection Limit,'' of this Part 136.

\5\ The method may be extended to include a-BHC, ?-BHC, endosulfan I, endosulfan II, and endrin. However, when they are known to exist,
Method 608 is the preferred method.

\7\ Each analyst must make an initial, one-time, demonstration of their ability to generate acceptable precision and accuracy with Methods 608 and 625
(See Appendix A of this Part 136) in accordance with procedures given in Section 8.2 of each of these methods. Additionally, each laboratory, on an on-
going basis, must spike and analyze 10% of all samples analyzed with Method 608 or 5% of all samples analyzed with Method 625 to monitor and evaluate
laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any parameter falls outside the warning limits,
the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate regulatory compliance. These
quality control requirements also apply to the Standard Methods, ASTM Methods, and other Methods cited.
Note: These warning limits are promulgated as an ``Interim final action with a request for comments.''

results must be added to obtain the ``total''.
