1.1.1 Incident Category
Removal Evaluation and Removal Action
1.1.2 Site Description
Two pits and a large disposal area on agricultural land currently being farmed for concord grapes.
1.1.2.1 Location
37704 North District Line Road, Prosser, WA 99350, Benton County
1.1.2.2 Description of Threat
Heat produced by the decomposing piles in excess of 1000 degrees F. Unrestricted access has led to several people walking into the piles and being severely burned.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
Heat readings in several areas were measured to be in excess of 1000F, accompanied by smoldering humous material. Removal Evaluation results for SVOC, pesticides, herbicides and metals show exceedances of RSLs only for arsenic and vanadium. No MTCA exceedances. Background levels for arsenic and vanadium were higher than the concentrations in the waste samples.
