Chloroform results
MS0440003 , Columbus Light & Water
35 samples have been analysed for Chloroform at Columbus Light & Water.
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 Chloroform result
The table below lists 1–10 of 35 samples, newest first — collected June 27, 2016 to June 22, 2026.
10 Chloroform results from the 10 samples listed here: 4 detected, 6 not detected. Those samples also carried 52 results for other analytes, which are on the full results page.
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 The location on record identifies a private home, and we do not publish those.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.
