TTHM results
MS0010007 , Oakland Water Works
24 samples have been analysed for TTHM at Oakland Water Works.
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 TTHM result
The table below lists 1–10 of 24 samples, newest first — collected February 28, 2024 to July 23, 2025.
10 TTHM results from the 10 samples listed here: 10 detected, 0 not detected. Those samples also carried 32 results for other analytes, which are on the full results page.
We withheld the location of 2 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 The location on record identifies a private home, and we do not publish those.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.
