1,1-Dichloroethylene results

MS0540067 , Concord-Macedonia W/A

26 samples have been analysed for 1,1-Dichloroethylene at Concord-Macedonia W/A.

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.

Every 1,1-Dichloroethylene result

The table below lists 1–10 of 26 samples, newest first — collected May 13, 2009 to June 25, 2024.

10 1,1-Dichloroethylene results from the 10 samples listed here: 0 detected, 10 not detected. Those samples also carried 200 results for other analytes, which are on the full results page.

Units in this table

1,1-Dichloroethylene is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

1,1-Dichloroethylene results for Concord-Macedonia W/A, from 1 to 10 of 26 samples shown analysed for it, newest first. This view leaves out other analytes on the same samples. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
