This study was undertaken in partnership with state and EPA Regional Air and Water Offices in order to assist developing and implementing strategies to achieve state water quality standards for mercury. This report summarizes the application of several air quality modeling systems and data analysis tools to support an assessment of the sources of airborne mercury and their contribution to water quality impairment and fish contamination throughout the continental U.S. The objective of this study was to use atmospheric deposition modeling to quantify contributions of specific sources and source categories to mercury deposition within each of the lower 48 states. It is expected that the results of this study will provide state and local air and water quality agencies with (1) an improved understanding of the sources and mechanisms contributing to mercury deposition; (2) supporting information for future development of Total Maximum Daily Loads (TMDLs); and (3) assistance in developing implementation plans for TMDLs and related activities designed to help achieve water quality standards.
