| Description | The purpose of this study was to collect data to support development of numeric values under Washington’s Model Toxic Control Act (MTCA) for ecological screening of soils contaminated with petroleum products. Ecology’s Toxics Cleanup Program specifies procedures for establishing cleanup levels at sites where there has been a release of petroleum and its associated hazardous substances. When released to the environment, these complex mixtures of hydrocarbon break down (termed weathering) at different rates so that the properties of the mixture are different both physically and chemically than the composition at the time of the release. To support the development of ecological screening values for gasoline, diesel, and heavy oil contamination in weathered soils, Ecology collected toxicity data from laboratory bioassay tests on soils collected around Washington State. Results from gasoline and diesel range organics analysis support using 120 mg/kg for Gasoline Range Organics and 260 mg/kg Diesel Range Organics for soil screening levels under MTCA for protection of soil biota. Screening levels of 120 mg/kg for Gasoline Range Organics and 1,600 mg/kg for Diesel Range Organics were considered appropriate protection for plants. |
