Here’s the release from the American Water Works Association:
A new AWWA report updates estimated costs of an anticipated perchlorate standard being developed by the US Environmental Protection Agency.
The new cost-impact assessment updates a 2009 review by including additional treatment strategies and accounting for regulatory limits already in place in California and Massachusetts.
In addition to ion exchange, this assessment considers also costs associated with blending, source abandonment and development of new sources. In all, the estimated national compliance costs for a perchlorate maximum contaminant level ranging from 2 to 24 ppb is smaller than estimated compliance costs for other drinking water regulations.
