Toxicity Evaluation of Petroleum Hydrocarbon-Contaminated Soils at the Presidio of San Francisco
As part of the National Parks Service recreation of historical wetlands at the Presidio of San Francisco, Pacific EcoRisk is evaluating the toxicity risk posed by soils and groundwaters which have been contaminated with petroleum hydrocarbons during the previous military use of the Presidio. These evaluations include marine sediment toxicity tests, and sediment-elutriate testing using mysid shrimp and the bivalve embryo development test.

Natural Resources Damage Assessment (NRDA) of Petroleum-Contaminated Groundwater Seepage to Southern California Intertidal Areas
As part of an NRDA Evaluation of petroleum-contaminated groundwater which is seeping into intertidal areas in Southern California, Pacific EcoRisk is preparing and providing evaluations of the toxic effects of Water Accommodated Fraction (WAF) of the crude oil to marine/estuarine crustaceans.
