Cis-1,2-Dichloroethylene results

MS0580007 , Randolph Water Association #1

37 samples have been analysed for Cis-1,2-Dichloroethylene at Randolph Water Association #1.

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.
