Description:
Regulations governing the disposal of hazardous wastes led to an assessment for geothermal solid wastes for potentially hazardous properties. Samples were collected from three active geothermal sites in the western United States: The Geysers, Imperial Valley, and northwestern Nevada. Approximately 20 samples were analyzed for corrosivity, EP toxicity, radioactivity, and bioaccumulation potential. The samples were further characterized by analysis for cations, anions, moisture content, priority pollutants, and additional trace metals in the leachate. In addition, an aqueous extraction was conducted at ambient pH. This study characterized samples from a limited geographical area and results cannot be extrapolated to other geothermal resource areas (GRA).
