A strategy to facilitate cleanup at the Mare Island Naval Station
A strategy based on an early realistic estimation of ecological risk was devised to facilitate cleanup of installation restoration units at the Mare Island Naval Station. The strategy uses the results of 100 years of soil-plant studies, which centered on maximizing the bioavailability of nutrients for crop growth. The screening strategy classifies sites according to whether they present (1) little or no ecological risk and require no further action, (2) an immediate and significant risk, and (3) an ecological risk that requires further quantification. The strategy assumes that the main focus of screening level risk assessment is quantification of the potential for abiotic-to-biotic transfer (bioavailability) of contaminants, especially at lower trophic levels where exposure is likely to be at a maximum. Sediment screening criteria developed by the California Environmental Protection Agency is used as one regulatory endpoint for evaluating total chemical concentrations. A realistic estimation of risk is then determined by estimating the bioavailability of contaminants.
