*We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During a 28 hour period beginning on 2/14/2026 we did not monitor for combined filter effluent turbidity and therefore cannot be sure of the quality of your drinking water during that time.*
