New analytical methods and sampling techniques are enabling clean water facilities to measure levels of mercury that were previously undetectable. Because of the U.S. Environmental Protection Agency’s (EPA) new human health criterion for methylmercury in fish tissue and the increasing number of fish advisories based on mercury. More clean water agencies are facing mercury requirements. While NACWA believes each community must make the decisions that are right for its citizens, the Association favors a national, holistic strategy that fairly and equitably takes into account the various sources of mercury – air, industrial, national and international.
