Models methyl tertiary butyl ether (MTBE) and other organic compounds (specifically benzene, toluene, ethylbenzene, and xylenes [BTEX]) in lakes and reservoirs and calibrates this model in two reservoirs. Also investigates several options for controlling MTBE and other fuel-related contaminants in water bodies. Provides guidance for water utilities and agencies to minimize the impacts of MTBE and other contaminants in surface waters. Includes a diskette.
