1988-1996 WRST Hazardous Waste Inventory and Removal Program
Rosenkrans D and Rosenkrans DS. 1988-1996 WRST Hazardous Waste Inventory and Removal Program
WRST conducted a survey and sampling of hazardous waste materials that were abandoned at numerous mining (and other) sites throughout the Park. The project was restricted to publicly owned lands. Samples were collected in accordance with Environmental Protection Agency safety standards and were subjected to flashpoint testing or laboratory chemical analysis to determine their identity. The suggested actions were removal of all hazardous materials found, and elimination or mitigation of physical hazards. The alternative to the suggested removal action was no action which would have allowed the hazardous materials to enter the park soils and water, as well as, continue to pose a significant safety risk to park visitors and NPS employees .
