Trans-1,2-Dichloroethylene results

MS0110002 , C S & I Water Assn #1

31 samples have been analysed for Trans-1,2-Dichloroethylene at C S & I Water Assn #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.
