About Our Water
The City of Pewaukee Water & Sewer Utility routinely monitors the city’s drinking water according to federal and state regulations. The annual Consumer Confidence Report is designed to inform you about the quality of the drinking water the City delivers to you every day. This annual report communicates the source of the City's water and summarizes the detected compounds from the sampling results for the previous years' testing. It is our goal to provide all residents and businesses in the City of Pewaukee with safe and dependable drinking water.
What is HARDNESS in drinking water? Hard water is high in dissolved minerals, both calcium and magnesium. As water moves through soil and rock, it dissolves small amounts of these naturally-occurring minerals and carries them into the ground water supply. Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around your well and its water supply, you can end up with hard water. Hardness does not pose a health risk and is not regulated by state and federal agencies. In fact, calcium and magnesium in your drinking water can help ensure you get the average daily requirements for these minerals in your diet.
City of Pewaukee Average Hardness: 361 PPM (21.2 grains)
FLUORIDE is a natural substance that is found naturally in rocks and soil. As water passes through the earth, it absorbs fluoride. As a result, most water contains some amount of fluoride. The City of Pewaukee Water Utility does not add fluoride to the drinking water.
City of Pewaukee Average Fluoride: 0.44 PPM (naturally-occurring)
