Manager: radon levels fell after Lake well removal; PFAS tests show no detection

General Manager Tom Griesbach told the board that a radon reading had dropped roughly 75% after the Lake well was taken out of production, a change staff attributed to adjusting well use. Certified Water Operator Kirk Klemcke reported that regular monthly bacterial testing was satisfactory and that radon testing on the Summit tank returned very low results; he said bottles for additional testing have been ordered.

Klemcke also noted PFAS testing so far showed no detection and that the cost is $260 per test; he said he is not certified to perform PFAS testing himself and that Geo Synthetics can perform those analyses. Griesbach also raised operational issues: well-site access is restricted (citizens are not allowed on site without authorization and accompaniment) and there is currently no internet service at well sites, which limits options for camera monitoring; he suggested motion-activated game cameras as a low-bandwidth option.
