Impact/Purpose:
The objective of this research effort is to develop analytical methods to be used to measure the occurrence of priority water pollutants in the nation’s drinking water supplies. To accomplish this objective, ORD/NERL scientists must first coordinate with staff from the Office of Ground Water and Drinking Water (OGWDW) to identify the most appropriate chemical contaminants for which analytical methods need to be developed, and then ORD/NERL must develop, and demonstrate the applicability of, new or improved analytical methods that are specific, sensitive, and practical enough for application in commercial laboratories as part of the UCMR monitoring efforts.
Description:
The 1996 amendments to the Safe Drinking Water Act (SDWA) required EPA to establish a Contaminant Candidate List (CCL), that contains a list of drinking water contaminants that the Agency will consider for future regulation. EPA must make a regulatory determination on a minimum of five contaminants every five years. The first CCL was published in 1998, and updates were anticipated every five years thereafter. One of the key pieces of information that must be available in order to make a regulatory determination is nationwide occurrence data for the chemical contaminants under consideration. Historically, EPA has collected the necessary occurrence data under its Unregulated Contaminant Monitoring Regulations (UCMR). Under the UCMR, monitoring is conducted at selected drinking water utilities for specific contaminants of interest. The chemical analyses are usually performed by the utilities or by commercial laboratories. To meet the requirements of monitoring under the UCMR program, the analytical methods developed should be specific, sensitive, and practical enough for application in commercial laboratories. This task will focus on the development of analytical methods for chemicals identified on future CCLs or emerging contaminants not yet listed on the CCL. These methods will be used for the collection of occurrence data under future UCMRs.
