National Primary and Secondary Drinking Water Regulations: Analytical Methods for Regulated Drinking Water Contaminants.

EPA is promulgating the use of several new analytical methods and updated versions of previously approved methods for a number of regulated contaminants in drinking water. At the same time, the Agency is withdrawing approval of outdated methods or outdated versions of the same methods. The purpose of the rule is to approve new methods, withdraw outdated methods, and update older methods for analysis of regulated contaminants in drinking water. The rule is expected to eliminate unnecessary duplication by withdrawing older versions of the same method, and satisfy public requests for approval of new technologies in drinking water analyses.
