A Technical Basis for Evaluating Soil as a Medium of Exposure

Abstract

ABSTRACT

Exposure to soil contaminated by hazardous waste due to direct contact can represent a potential threat to public health. However, a consistent approach for evaluating this medium of exposure has been lacking. A methodology was recently established to develop health-based exposure criteria known as Applied Action Levels for soil contact (AAL_{soil contact}). Sampling objectives to utilize these criteria have also been established. Taken together, the AAL_{ssoil contact} criteria and appropriate sampling objectives provide a technical basis for evaluating soil as a medium of exposure.
