Monochloroacetic Acid results

MS0610016 , Monterey Water Assn-West

28 samples have been analysed for Monochloroacetic Acid at Monterey Water Assn-West.

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 Monochloroacetic Acid result

The table below lists 1–10 of 28 samples, newest first — collected July 10, 2018 to November 24, 2025.

10 Monochloroacetic Acid results from the 10 samples listed here: 1 detected, 9 not detected. Those samples also carried 90 results for other analytes, which are on the full results page.

Units in this table

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

We withheld the location of 3 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Monochloroacetic Acid results for Monterey Water Assn-West, from 1 to 10 of 28 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.
