Analytical Methods Approved  for Drinking Water Compliance

Monitoring of Organic Contaminants
Analysis for the following contaminants shall be conducted in accordance with the methods in the following table, or their equivalent as determined
by EPA. The methods and monitoring requirements for these contaminants are specified in 40 CFR 141.24. Additional methods are listed in
Appendix A to Subpart C of Part 141.

The CFR is the legal reference for approved methods and takes precedent over this table. The table should accurately reflect the analytical methods
information published in 40 CFR 141. If discrepancies are found, please notify the Safe Drinking Water Hotline (800-426-4791) so that EPA can
correct the table.

Note: This method may not be used for the analysis of atrazine in any
system where chlorine dioxide is used for drinking water treatment.
In samples from all other systems, any result for atrazine generated by
Method AG-625 that is greater than one-half the maximum
contaminant level (MCL) (in other words, greater than 0.0015 mg/L
or 1.5 |ig/L) must be confirmed using another approved method for
this contaminant and should use additional volume of the original
sample collected for compliance monitoring. In instances where a
result from Method AG-625 triggers such confirmatory testing, the
confirmatory result is to be used to determine compliance.
