Cis-1,2-Dichloroethylene results

MS0700014 , Three Forks Water Association

16 samples have been analysed for Cis-1,2-Dichloroethylene at Three Forks Water Association.

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.
