Every Lead result

The 5 samples analysed for this analyte collected between September 26, 2024 and September 26, 2026 are listed below, newest first.

5 Lead results from the 5 samples listed here: 1 detected, 4 not detected. Those samples also carried 5 results for other analytes, which are on the full results page.

We withheld the location of 5 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 The location on record identifies a private home, and we do not publish those.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.
