Propylene glycol cleanup levels by state
- CAS 57-55-6
- 2 states
CAS 57-55-6 is in the cleanup-level tables of 2 states in this handbook: Florida (Propylene glycol) and Texas (Propylene glycol). 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 Propylene glycol, DEP's cleanup target level tables print 140,000 ug/L as the groundwater criterion and 560 mg/kg for soil leachability based on groundwater.

Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Propylene glycol, TCEQ's Tier 1 table prints 370 mg/kg for TotSoilComb and 940 mg/kg for GWSoilIng (residential soil, 0.5 acre source area), and 490 mg/L for GWGWIng (residential groundwater).
- 370mg/kg 3.7E+02 TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 940mg/kg 9.4E+02 GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 490mg/L 4.9E+02 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.
