Analytical Methods Developed by the Office of Ground Water and Drinking WaterThe Office of Ground Water and Drinking Water's (safewater) Technical Support Center (TSC) is one of the many EPA offices responsible for coordinating and developing analytical methods for drinking water. To date, TSC has developed, or participated in the development, of 21 methods for the analyses of a variety of chemical constituents in water. Nine of these, 504.1, 507, 508, 508.1, 509, 515.1, 531.1, 551.1, and 552.2 can be found in "Methods for the Determination of Organic Chemicals In Drinking Water, Supplement III," available through NTIS by requesting order number PB95-261616. Eight additional methods, 300.1, 314.0, 317.0 Rev. 1.0, 515.3, 526, 532, 556 (jointly developed with ORD) and 556.1 can be found in "Methods for the Determination of Organic and Inorganic Compounds in Drinking Water, Volume 1" (EPA815-R-00-014) available through NSCEP and individually listed below in downloadable electronic format. The remaining six, EPA Methods 317.0 Rev. 2.0, 326.0, 327.0, 515.4, 531.2 and 552.3, have yet to be included in a manual and are currently stand alone methods which are available electronically below. Some, but not all, of these methods have been promulgated as approved methods for compliance monitoring of specific parameters under the Safe Drinking Water Act. As a result of the recently published, "Analytical Methods for Chemical and Microbiological Contaminants and Revisions to Laboratory Certification Requirements" [64 FR 67449], all of the methods listed in "Methods for the Determination of Organic Chemicals In Drinking Water, Supplement III," except Method 515.1, Rev. 4.1, have been promulgated as approved methods. Also, Method 300.1 has been promulgated as an approved method for bromate and chlorite under the Stage 1 Disinfectants and Disinfection Byproducts Rule (Dec 16, 1998) [63 FR 69389]. Method 314.0 has been promulgated as the approved method [42 FR 11371] for assessment monitoring of perchlorate under the Unregulated Contaminant Monitoring Regulation (UCMR). EPA recommends that laboratories interested in using any of the other methods for compliance monitoring check the Federal Register to determine if and when these methods are approved. Questions or comments about these methods should be addressed to the Safe Drinking Water Hotline at 1-800-426-4791, or http://www.epa.gov/OGWDW/drinklink.html.EPA Method 300.1 - Determination of Inorganic Anions in Drinking
