AWWA submits comments on EPA’s draft CCL4

AWWA has submitted comments to the EPA on the draft Fourth Contaminant Candidate List (CCL4). The draft CCL4, originally published in the Federal Register on February 4, 2015, listed 100 chemicals and 12 microbial contaminants. However, AWWA has recommended that the final CCL4 only include 20-50 compounds and that the EPA “use an alternative contaminant identification process to select a shorter list of compounds of greatest potential concern”.
