Tin cleanup levels by state

CAS 7440-31-5
3 states

CAS 7440-31-5 is in the cleanup-level tables of 3 states in this handbook: Florida (Tin), Pennsylvania (TIN) and Texas (Tin). 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 TIN, DEP's Statewide Health Standard tables print 21,000 ug/L for residential groundwater in a used aquifer with TDS up to 2500, 130,000 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: 2,100 mg/kg as 100 X GW MSC and 190,000 mg/kg as the generic value.
