Ourconstantgoalistoprovideyouwithasafeanddependablesupplyofdrinkingwater.Wewant you to understand the efforts we make to continually improve the water treatment process and protect our water resources. Weare committedto ensuring thequality of your water. Our water sourceshavebeendeterminedtobefromgroundwatersources. Ourwatersources areCoveHole Spring, Lower Funk Canyon Spring,UpperFunk Canyon8pring, and theFunk Canyon Well. TheDrinking Water Source Protection PlanforSterlingTownWaterSystemis availablefor your review.Itcontains information about source protection zones, potential contamination sources andmanagementstrategiesto protect ourdrinkingwater.

SterlingTownWaterSystemroutinelymonitorsforconstituentsinourdrinkingwaterin accordance with the Federal and Utah State laws. Thefollowing table shows the results of our monitoring for the period of January 1" to December 31", 2023. All drinking water, including bottled drinking water, may be reasonablyexpectedto contain at least small amounts of some constituents. It'simportant torememberthat the presenceof these constituents does not necessarily poseahealthrisk.
