EPA has published a final rule approving 99 new methods for testing for the presence of contaminants in drinking water, and thus determining compliance with the national primary drinking water standards. See 73 Fed. Reg. 31616 (June 3, 2008). EPA states that each of the new methods is as effective for assessing the presence of contaminants as the current methods. The new methods pertain only to existing contaminants, and are not related to the draft of the third Contaminant Candidate List. The new rule was adopted using an expedited approval process rather than a formal rulemaking.
