Impact/Purpose:
Develop an analytical method for the analysis of alachlor ESA and other acetanilide pesticide degradation products. The draft method, suitable for use in assessing occurrence of the pesticide degradation products as part of the Unregulated Contaminant Monitoring Rule (UCMR), will be delivered to OGWDW by February 2004. The final peer-reviewed method was delivered in September 2004.
Description:
The Contaminant Candidate List (CCL), which was promulgated in March 1998, includes 50 chemical and 10 microbiological contaminants/contaminant groups. At the time of promulgation, analytical methods were available for 6 inorganic and 28 organic contaminants. Since then, 4 analytical methods have been pubished encompassing 12 additional analytes leaving only 4 chemical contaminant groups that still require method development. Method development work for microbiological contaminants will result in a method for Aeromonas later this year. Much research still remains in this area. This paper summarizes some of the technical challenges encountered during the method development projects, and updates the current status of the ongoing efforts to develop analytical methods for CCL contaminants.
