Iron cleanup levels by state
- CAS 7439-89-6
- 3 states
CAS 7439-89-6 is in the cleanup-level tables of 3 states in this handbook: Florida (Iron), Pennsylvania (IRON) and Texas (Iron). 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 Iron, DEP's cleanup target level tables print 300 ug/L as the groundwater criterion and 53,000 mg/kg for residential direct exposure to soil.
- 300ug/L Groundwater Criteria Table I: Groundwater and Surface Water Cleanup Target Levels
- 53,000mg/kg 53000 Direct Exposure - Residential Table II: Soil Cleanup Target Levels
Pennsylvania
- PA DEP
- Act 2 Statewide Health Standards
For IRON, DEP's Statewide Health Standard tables print 150,000 mg/kg for residential soil direct contact from 0 to 15 feet and 300 µg/L as a secondary maximum contaminant level.
- 150,000mg/kg 150000 0-15 feet Table 4a: Medium-Specific Concentrations (MSCs) for Inorganic Regulated Substances in Soil: A. Direct Contact Numeric Values Residential MSC
- 300µg/L SMCL Table 2: Secondary Contaminants Secondary Contaminants
Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Iron, TCEQ's Tier 1 table prints no value for TotSoilComb and no value for GWSoilIng (residential soil, 0.5 acre source area), and no value for GWGWIng (residential groundwater).
- ─ TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- ─ GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- ─ GWGWIng Table 3: Tier 1 Groundwater PCLs - Residential and Commercial/Industrial Residential
Each agency's own publication governs: its current table, or the published rule where the agency says so. This page is a reference copy and not a cleanup decision. Check each agency's page before relying on a value.
