1,1-Dichloroethylene results

MS0240049 , Keesler Air Force Base

180 samples have been analysed for 1,1-Dichloroethylene at Keesler Air Force Base.

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 180 samples, newest first — collected March 5, 2024 to July 7, 2026.

10 1,1-Dichloroethylene results from the 10 samples listed here: 0 detected, 10 not detected. Those samples also carried 201 results for other analytes, which are on the full results page.

1,1-Dichloroethylene results for Keesler Air Force Base, from 1 to 10 of 180 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.
