Chromium (VI) cleanup levels by state
- CAS 18540-29-9
- 3 states
CAS 18540-29-9 is in the cleanup-level tables of 3 states in this handbook: Florida (Chromium (hexavalent)), Pennsylvania (CHROMIUM VI) and Texas (Chromium (VI)). Each state's numbers are below as its agency prints them. The states run different programs and do not define their values the same way, so a number from one is not the same measure as a number from another. A state that lists the substance under another CAS number, or without one, is not shown here.
Florida
- FL DEP
- Chapter 62-777 CTLs
- February 2005
For Chromium (hexavalent), DEP's cleanup target level tables print 210 mg/kg for residential direct exposure to soil.
- 210mg/kg Direct Exposure - Residential Table II: Soil Cleanup Target Levels
Pennsylvania
- PA DEP
- Act 2 Statewide Health Standards
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
Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Chromium (VI), TCEQ's Tier 1 table prints 120 mg/kg for TotSoilComb and 28 mg/kg for GWSoilIng (residential soil, 0.5 acre source area), and 0.1 mg/L for GWGWIng (residential groundwater).
- 120mg/kg 1.2E+02 TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 28mg/kg 2.8E+01 GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 0.1mg/L 1.0E-01 GWGWIng Table 3: Tier 1 Groundwater PCLs - Residential and Commercial/Industrial Residential
