CHROMIUM VI cleanup levels in Pennsylvania

PA DEP
Act 2 Statewide Health Standards
CAS 18540-29-9

For CHROMIUM VI, DEP's Statewide Health Standard tables print 37 mg/kg for residential soil direct contact from 0 to 15 feet, and two residential soil to groundwater values for a used aquifer with TDS up to 2500: 10 mg/kg as 100 X GW MSC and 190 mg/kg as the generic value.

37mg/kg 0-15 feet Table 4a: Medium-Specific Concentrations (MSCs) for Inorganic Regulated Substances in Soil: A. Direct Contact Numeric Values Residential MSC
10mg/kg 100 X GW MSC Table 4b: Medium-Specific Concentrations (MSCs) for Inorganic Regulated Substances in Soil: B. Soil to Groundwater Numeric Values Used Aquifers, TDS < = 2500, R
190mg/kg Generic Value Table 4b: Medium-Specific Concentrations (MSCs) for Inorganic Regulated Substances in Soil: B. Soil to Groundwater Numeric Values Used Aquifers, TDS < = 2500, R

These are the Pennsylvania Department of Environmental Protection's published values for CHROMIUM VI, from its Statewide Health Standard tables. DEP's page says the tables present the standards published November 20, 2021. Each value is shown as the agency prints it, with the same number written out beside it where that reads differently.
