Vernam cleanup levels by state
- CAS 1929-77-7
- 2 states
CAS 1929-77-7 is in the cleanup-level tables of 2 states in this handbook: Florida (Vernam) and Texas (Vernam). 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.
