Data presented in the report were collected during the third year of a research program designed to develop a method to assess ambient toxicity of living resource habitats in Chesapeake Bay for the purpose of identifying defined regions where ambient toxicity levels warrant further investigation. The goals of the study were to identify toxic ambient areas in the Chesapeake Bay watershed by using a battery of standardized, directly modified, or recently developed water column and sediment toxicity tests. The toxicity of ambient estuarine water and sediment was evaluated during the fall (1992) and spring (1993) at two stations each in the Wye River (Manor House and Quarter Creek), Nanticoke River (Sandy Hill Beach and Bivalve Harbor) and Middle River (Frog Mortar and Wilson Point) to address temporal and spatial variability.
