Refer to Table F-4b for summary of aquatic habitat goal sources. Lowest Estuary Goal = Lowest of Freshwater vs Marine chronic goals. Used for development of groundwater and soil screening levels. Aquatic Habitat Goals: Addresses potential impact on freshwater or marine aquatic habitats. Final screening levels are lowest of marine and freshwater criteria. See text for prioritization and selection of surface water quality screening levels. USEPA HH criteria for potential bioaccumulation of chemicals in aquatic life considered in surface water screening levels only (refer to main text). Drinking water goal substituted as aquatic habitat goal if latter was not available (see text). Review of aquatic ecotoxicty data for ethanol underway. Based on preliminary review of available data, chronic toxicity screening levels likely to be significantly greater than ceiling level of 50,000 ug/L (see Table I series). Refer to USEPA 2003b, ECOTOX database). Methyl tert-Butyl Ether: Interim salt water CCC proposed by Region 2 Water Quality Control Board (RWQCBSF, 1998b) TPH screening levels: Based on TPH screening levels published in SFRWQCB Board Orders.
