This article discusses the second Unregulated Contaminant Monitoring Rule (UCMR2) that will require a national sampling of water utilities to monitor for 26 high-priority unregulated contaminants, including perchlorate. The UCMR2 features an assessment monitoring
component that would have 3,910 public
water systems look for 11 priority
chemicals using six well-established
analytical methods. The rule
also includes a screening survey that would
have 1,122 systems monitor for 15 other
targeted chemicals using
specialized and less commonly used
methods.
Scheduled for promulgation by August
2006, the rule would apply to community
water systems (CWSs) and nontransient-
noncommunity water systems
(NTNCWSs). The article discusses the US Environmental Protection Agency's (USEPA) selection method for the 26 chemicals, the USEPA's request for a second monitoring for perchlorate, and possible additions to the final screening survey. Assessment monitoring process is described, along with the screening survey and state participation. Includes tables.
