In the U.S., households rely on regulated public water systems or privately maintained wells. Both types of supplies receive water testing to ensure homes get safe drinking water. However, if you have a private system, you are responsible for maintaining it. The guide below explains questions you might have about this.

What You Must Know About Water Tests

Why do I have to get my supply tested? 

In Wisconsin, every resident uses about 50 to 69 gallons of water daily. About 25% of the population drinks from private wells.

In both public and private systems, water may contain contaminants that cause health issues. Some particles don’t affect the taste or color of water, so you may not notice signs of contamination. Annual water testing allows you and your family to feel confident that your supply is safe for consumption. 

What are the health risks of contamination? 

A few common contaminants include bacteria, fertilizers, factory chemicals, copper, and lead. These pollutants can lead to diseases like E. coli and salmonella. Children, pregnant women, and seniors are more likely to develop health complications after drinking affected water. 

How often should I schedule water testing?

The U.S. Environmental Protection Agency (EPA) regulates public supplies and conducts routine testing.

On the other hand, private well owners are in charge of maintaining their own supplies. If you have a private well, you should get annual testing. However, if you live near agricultural or industrial zones, consider scheduling biannual tests since the risk of contamination from runoff is greater.

What should I do if my water is contaminated?

The government will issue an advisory when contamination is detected in public water systems. In this case, you’ll receive an advisory via mail and be instructed to boil water for at least one minute to kill bacteria. 

If you have a private well, there are a range of ways to filter out contaminants. For example, reverse osmosis systems remove parasites, including some that cause gastrointestinal illnesses. Professionals can install a single filter in your water main or one at every tap.
