Chlorotoluene, o- (2-chlorotoluene) cleanup levels by state
- CAS 95-49-8
- 3 states
CAS 95-49-8 is in the cleanup-level tables of 3 states in this handbook: Florida (Chlorotoluene, o-), Pennsylvania (CHLOROTOLUENE, O-) and Texas (Chlorotoluene, o- (2-chlorotoluene)). 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 Chlorotoluene, o-, DEP's cleanup target level tables print 140 ug/L as the groundwater criterion, 200 mg/kg for residential direct exposure to soil and 2.8 mg/kg for soil leachability based on groundwater.
- 140ug/L Groundwater Criteria Table I: Groundwater and Surface Water Cleanup Target Levels
- 200mg/kg Direct Exposure - Residential Table II: Soil Cleanup Target Levels
- 2.8mg/kg Leachability Based on Groundwater Table II: Soil Cleanup Target Levels
Pennsylvania
- PA DEP
- Act 2 Statewide Health Standards
For CHLOROTOLUENE, O-, DEP's Statewide Health Standard tables print 100 μg/L for residential groundwater in a used aquifer with TDS up to 2500, 4,400 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 20 mg/kg as the generic value.
- 100μg/L R Table 1: Medium-Specific Concentrations (MSCs) for Organic Regulated Substances in Groundwater Used Aquifers, TDS ≤ 2500
