This summer, the Environmental Protection Agency is expected to propose a maximum contaminant level (MCL) of 300 pCi/l for radon in drinking water. This anticipated MCL, if adopted, will affect the majority of water suppliers using groundwater in California, where most of wells likely exceed 300 pCi/l. This paper describes a study being performed for the Association of California Water Agencies (ACWA) to evaluate the economic impact of the proposed regulation on water suppliers in California.
