Chloral hydrate (1,1-ethanediol, 2,2,2-trichloro-) cleanup levels by state
- CAS 302-17-0
- 2 states
CAS 302-17-0 is in the cleanup-level tables of 2 states in this handbook: Florida (Chloral hydrate) and Texas (Chloral hydrate (1,1-ethanediol, 2,2,2-trichloro-)). 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 Chloral hydrate, DEP's cleanup target level tables print 70** ug/L as the groundwater criterion, 5,700 mg/kg for residential direct exposure to soil and 0.3 mg/kg for soil leachability based on groundwater.
- 70**ug/L Groundwater Criteria Table I: Groundwater and Surface Water Cleanup Target Levels
- 5,700mg/kg 5700 Direct Exposure - Residential Table II: Soil Cleanup Target Levels
- 0.3mg/kg Leachability Based on Groundwater Table II: Soil Cleanup Target Levels

** = Groundwater CTLs for class C carcinogens with no cancer slope factor were developed using the reference dose divided by a factor of 10, as described in the February 2005 'Final Technical Report: Development of Cleanup Target Levels (CTLs) for Chapter 62-777, F.A.C.'
Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Chloral hydrate (1,1-ethanediol, 2,2,2-trichloro-), TCEQ's Tier 1 table prints 6,700 mg/kg for TotSoilComb and 5.2 mg/kg for GWSoilIng (residential soil, 0.5 acre source area), and 2.4 mg/L for GWGWIng (residential groundwater).
- 6,700mg/kg 6.7E+03 TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 5.2mg/kg 5.2E+00 GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
