As part of its Wellhead Protection Program, the City collects groundwater samples from deep sentinel wells surrounding the Mint Farm wellfield every six months to look for changes in water quality. In addition to compliance sampling required by the Department of Health, the production wells are also sampled annually as part of wellhead protection. View summary reports and laboratory results from past sampling events in the Archive Center.
The most current sampling event occurred in October of 2019 but no report has been finalized yet.
The City uses a live data engine to compile and analyze the data contained in the semi-annual Water Quality Reports. This allows the data to be trended and visually displayed such that large volumes of data can be more easily monitored and interpreted.
