Trichloroacetic Acid results
MS0110002 , C S & I Water Assn #1
31 samples have been analysed for Trichloroacetic Acid 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.
Every Trichloroacetic Acid result
The table below lists 1–10 of 31 samples, newest first — collected May 10, 2011 to October 8, 2025.
10 Trichloroacetic Acid results from the 10 samples listed here: 9 detected, 1 not detected. Those samples also carried 60 results for other analytes, which are on the full results page.
Units in this table
Trichloroacetic Acid is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
We withheld the location of 4 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 The location on record identifies a private home, and we do not publish those.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.
