We often think about staying healthy through the food we eat, the physical activity we get and the preventive care we receive, but many other factors influence our health, too, especially those that we use every day, including water.
Access to clean water shouldn’t be taken for granted. When we understand where our water comes from and how to protect it, we can better protect our health.
Contaminated water can expose residents to bacteria, nitrates, arsenic and other substances that can cause illness or contribute to health problems. This is especially concerning for Iowans who rely on private wells. Unlike public water systems, private well owners are responsible for having their water tested and maintaining their own systems.
Public water systems are regularly monitored and tested to ensure they meet drinking water standards. For example, you can find both the Des Moines Water Works water quality report and the Xenia water quality report online.
For private wells, though, homeowners need to take an active role. The Iowa Department of Natural Resources recommends that private well water be tested at least once a year. Even water that looks, smells and tastes fine is not necessarily safe. The only way to know for sure is through laboratory testing. Well owners should also protect the surrounding area from potential sources of contamination, such as hazardous chemicals.
Septic systems also play an important role in water quality. A poorly maintained or failing septic system can allow bacteria and other contaminants to enter groundwater, potentially contaminating nearby wells. Inspections at least every three years, pumping the tank every three to five years and being mindful of what goes down the drain can help keep a septic system running properly and protect groundwater.
The Dallas County Health Department offers septic permits and inspections. We also offer free services for existing wells, including water testing. Learn more by contacting the department at 515-993-3750.
