EPA Updates the Environmental Chemistry Methods Index for Monitoring Pesticide Residues 

The U.S. Environmental Protection Agency=E2=80-(EPA) has=E2=80-updated the=E2=80-Environmental Chemistry Methods (ECM) Index, a list which currently includes 865 analytical methods for monitoring pesticide residues, primarily in soil or water.=E2=80-In the past year, 65 new analytical methods have been added to the ECM Index, including six methods for newly-registered pesticides. The ECM reports listed in the ECM Index were submitted to EPA by pesticide registrants to support submitted field and monitoring studies, and potential monitoring by states, tribes, and other entities.  

ECMs may be used in conjunction with Aquatic Life Benchmarks, which are estimated concentrations below which pesticides are not expected to present a risk of concern for freshwater organisms. Comparing concentrations of a pesticide in water using ECMs to Aquatic Life Benchmarks can be helpful in interpreting monitoring data and in identifying and prioritizing monitoring sites for further investigation.=E2=80-State, tribal, and local governments as well as international regulatory authorities and researchers may use these ECMs in their work. 

EPA intends to update the ECM Index quarterly and as new chemicals are registered.
