1,1,2-Trichloroethane results

MS0640022 , Okatoma Water Association #2

143 samples have been analysed for 1,1,2-Trichloroethane at Okatoma Water Association #2.

This is one analyte out of the system’s whole record. For what has ever been detected here, and when, see all chemical and radiological results; for everything the system is tested for, see the analyte list.

What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.

No date range is applied: this list draws on every sample on record. Show the last two years only.
