AWWA Releases Cost-Impact Study of Upcoming USEPA Perchlorate Regulations

The American Water Works Association (AWWA) has completed a cost-impact assessment of pending U.S. Environmental Protection Agency (USEPA) perchlorate regulations. It is an update to a 2009 assessment which includes additional treatment strategies and accounts for regulatory limits that are currently in place in California and Massachusetts. In addition to ion exchange, the new assessment considers the costs associated with blending, source abandonment, and development of new sources.

The AWWA says the estimated national compliance costs for a perchlorate maximum contaminant level (MCL) ranging from two to 24 parts per billion (ppb) is smaller than estimated compliance costs for other drinking water regulations because only a small number of public water systems are expected to be affected by any potential perchlorate regulation. However, the systems that are affected will be impacted by the costs associated with compliance. “Because only a small number of systems would carry the cost, we expect the economic impact to individual systems to be significant. Small water systems in particular could see treatment costs increase by three dollars per 1,000 gallons,” says Kevin Morley, AWWA Government Affairs, in a news release.
