Soil Metal Bioavailability

SAMPLE PLANNING GUIDANCE TOOL

This tool estimates Type 1 and 2 decision errors when incorporating RBA estimates into cleanup decisions for lead (Pb) and arsenic (As) contaminated soils, where Type 1 error is defined as concluding the DU does not need cleanup action when it should (false compliance), and Type 2 error is defined as concluding the DU needs cleanup action when it doesn't (false exceedance).
