Eden Prairie's water has received a clean bill of health, according to an annual report from the city.
Tests for seven contaminants found that all were below the levels the federal government requires for drinking water, the report says. The results cover the year of 2018.
The report tested for copper and lead; fluoride, which Minnesota requires be added to drinking water to promote strong teeth; chlorine, which is added to water to control microbes; cis-1,2-dichloroethylene, which is discharged from chemical factories; and haloacetic acids and trihalomethanes, which are byproducts of drinking water disinfection.
The city draws its drinking water from 15 groundwater wells from the Jordan-Prairie du Chien aquifer, which range in depth from 381 to 420 feet, the report says. The water is treated to remove minerals, or "soften" it, which the report says results in:
- More effective soaps and detergents;
- Less mineral staining on fixtures;
- Cloth that is softer, lasts longer and stays whiter;
- Increased lifespan of water appliances like dishwashers, water heaters and washing machines; and
- No need for personal water softeners and no salt brine discharge to the wastewater system.
The city's public water system serves around 63,000 people, according to the Department of Health Source Water Assessment. Lion's Tap and Eaton Corporation, both in Eden Prairie, have separate water systems and draw their own drinking water. The Lion's Tap water system, 16180 Flying Cloud Drive, serves around 100 people and Eaton Corporation's water system, 14900 Technology Drive, serves around 320 people.
