EPA Approves Water Contaminant Testing Methods

The U.S. Environmental Protection Agency has approved 12 new, alternative (and optional) testing methods for use in measuring the levels of contaminants in drinking water and determining compliance with national primary drinking water regulations.

The Safe Drinking Water Act (SDWA) authorizes EPA to streamline approval of the use of alternative testing methods through publication in the Federal Register. This expedited approach provides public water systems, laboratories, and primacy agencies with more timely access to new measurement techniques and greater flexibility in the selection of analytical methods, thereby reducing monitoring costs while maintaining public health protection.

The 12 alternative methods test for Dalapon; Radium-226; Uranium; Radioactive Cesium, Iodine and Gamma emitters; Tritium; and E. coli in drinking water.
