Science Related to Chemical Releases
Chemical or hazardous substance spills can occur during production, transportation, storage, and disposal activities. They kill fish and wildlife, destroy habitat, and contaminate critical resources. These environmental injuries can linger for decades and be difficult to assess. The impact of these type spills is complex and depends upon where they occur, the amount spilled and the chemical properties of the substance. Factors such as toxicity, transport properties and environmental persistence need to be assessed and considered. USGS has capabilities and expertise that can aid with site characterization, injury determination, and restoration.
