Full Description

Broad Spectrum Testing (BST) can be used by a Public Water Supply (PWS) as an effective tool for collecting both voluntary and compliance monitoring data for the CCR. Environmental Health Laboratories introduced its BST program in late 1997 to produce extended data sets with reporting limits that meet or surpass those currently required for routine compliance monitoring in a cost-effective manner. Only five analytical methods encompassing the techniques of GC/MS, ICP/MS, Ion Chromatography, and LC/PDA/MS, are needed to analyze for over 460 metal, organic, and inorganic contaminants, including the majority of the regulated parameters. Three of these methods are simple extensions of current EPA approved methods, and the other two will be submitted for approval under the proposed Streamlining Initiative when it is promulgated. The paper focuses on the following: the impact of the new CCR regulation on the PWS industry; the integration of a cost-effective BST program to help a PWS maintain current CCRs and promote public health; cost comparisons between conventional compliance SDWA methodology and BST; and, method validation data such as calibration, precision/accuracy, and method detection limits (MDL) for one of the BST methods.
