DRINKING
WATER METHODS
The Office of Research and Development, National Exposure Research Laboratory
(NERL), which was formerly identified as the Environmental Monitoring
Systems Laboratory (EMSL), has historically been one of the most active
EPA laboratories conducting drinking water methods research. Numerous
analytical methods have been written and are available through the NTIS.
Below are some recently developed analytical methods for drinking water.
The methods are presented in Adobe Acrobat ® PDF format. EPA recommends
that laboratories interested in using these methods for compliance monitoring
check the Federal Register to determine if and when these methods are
approved.
Questions or comments about these methods can be addressed to NERL and
Faxed to 513-569-7757 or send an E-mail to: DWmethods.help@epa.gov.
Additional assistance can be found by contacting the Safe Drinking Water
Hotline at 1 (800) 426-4791, or hotline-sdwa@epa.gov.
