Chemical and radiological sample results
MS0700015 , Lake Mohawk Estates Water Sysm
8 of the 13 analytes this system has been tested for have been detected at least once, across 53 samples on record.
The other 5 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.
Across all 53 samples on record, detections range from June 19, 2007 to April 29, 2025. These figures cover the whole record.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
What has been detected, ever
Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

The most recent samples, result by result
The table below lists 11–20 of 53 samples, newest first — collected September 5, 2017 to August 16, 2021. The summary above covers all 53.
29 results from the 10 samples listed here: 13 detected, 16 not detected. Across the whole record it is 74 of 138. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
Units in this table
Total Haloacetic Acids (Haa5) is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
