Well owners — is your water safe to drink?

By Mike Ekberg, Manager for Water Resources Monitoring and Analysis

Hey well owners, when’s the last time you had your drinking water tested? If you’re like many well owners in the United States, you probably have never tested your water. Why should you bother? You have plenty of water and it tastes good, right?

If you want to be sure your drinking water is safe, you need to get it tested.

Test at least annually
The National Ground Water Association (NGWA) recommends well owners test their water at least annually for bacteria, nitrates, and contaminants specific to your area. Consider more frequent testing if:
• There is a change in taste, odor, or appearance of well water.
• The well has a history of contamination.
• The well is near a septic system.
• There have been recurring incidents of gastrointestinal illness.
• An infant is living in the home.
• Home water treatment equipment has been installed.

In our area, I recommend the following tests:
E. coli – E. coli bacteria is a specific indication of fecal contamination in the well. Its presence is a warning that disease-causing bacteria may have entered the well.

Nitrate – Nitrate gets into drinking water from fertilizers, manure, and septic systems. It also occurs naturally. High nitrate levels present a health concern for infants if the water is mixed with formula. High nitrate levels can also suggest other toxins such as bacteria and pesticides.

Arsenic – Arsenic is naturally occurring in groundwater. It’s linked to various cancers and other health issues.

Manganese – Manganese also occurs in nature and can be present in groundwater. At high enough levels, it may cause brain damage.

Lead – Lead typically gets into drinking water from corroded pipes and plumbing fixtures. If your home was built prior to 1986, it’s more likely to have lead pipes, fixtures, and solder.

To help you get started, MCD partners with various counties and soil and water conservation districts to offer free, confidential well water sampling for nitrates, nitrites, and iron through Test Your Well events.
