Propylbenzene, n- cleanup levels by state
- CAS 103-65-1
- 2 states
CAS 103-65-1 is in the cleanup-level tables of 2 states in this handbook: Pennsylvania (PROPYLBENZENE, N-) and Texas (Propylbenzene, n-). 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.
Pennsylvania
- PA DEP
- Act 2 Statewide Health Standards
For PROPYLBENZENE, N-, DEP's Statewide Health Standard tables print 2,100 μg/L for residential groundwater in a used aquifer with TDS up to 2500, 10,000 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: 210 mg/kg as 100 X GW MSC and 400 mg/kg as the generic value.
- 2,100μg/L 2100 R Table 1: Medium-Specific Concentrations (MSCs) for Organic Regulated Substances in Groundwater Used Aquifers, TDS ≤ 2500
- 10,000mg/kg 10000 0-15 feet Table 3a: Medium-Specific Concentrations (MSCs) for Organic Regulated Substances in Soil: A. Direct Contact Numeric Values Residential
- 210mg/kg 100 X GW MSC Table 3b: Medium-Specific Concentrations (MSCs) for Organic Regulated Substances in Soil: B. Soil to Groundwater Numeric Values Used Aquifers, TDS ≤ 2500, Residential
- 400mg/kg Generic Value Table 3b: Medium-Specific Concentrations (MSCs) for Organic Regulated Substances in Soil: B. Soil to Groundwater Numeric Values Used Aquifers, TDS ≤ 2500, Residential
Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Propylbenzene, n-, TCEQ's Tier 1 table prints 2,200 mg/kg for TotSoilComb and 45 mg/kg for GWSoilIng (residential soil, 0.5 acre source area), and 0.98 mg/L for GWGWIng (residential groundwater).
- 2,200mg/kg 2.2E+03 TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 45mg/kg 4.5E+01 GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 0.98mg/L 9.8E-01 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.
