Owning your own water well gives you a unique opportunity to completely control what’s in your water. However, it’s not uncommon for residential water systems–both private wells and public water supplies—to become contaminated. Therefore, it’s crucial to know what hazards to look out for. You’ll then be prepared to work with your well drilling contractor to keep your water quality perfect.

A Guide to Well Water Contamination

1. Bacteria

There are many microbiological contaminants that are naturally in the environment, such as from animal waste or the soil. If it gets into your well, that bacteria can be harmful for you to consume, causing health problems ranging from dysentery to hepatitis.

Common bacteria found in Wisconsin’s environment include E. coli and leptospirosis. Bacteria testing should be done annually or immediately after any flooding event.

2. Nitrates

Nitrates also naturally occur in sewage systems, fertilizers, animal waste, and industrial complexes. They will enter the well through water runoff. Consuming harmful levels of nitrates can cause health problems, and is particularly dangerous for pregnant women, infants, people with weakened immune systems, and seniors. Nitrate testing should be done annually or immediately after any flooding event.

3. Heavy Metals

Heavy metals can enter your water supply through corroding plumbing or runoff from manufacturing plants. These include lead, copper, chromium, arsenic, and selenium. Consuming too many heavy metals has been linked to intestinal problems, cancer, and kidney and liver damage. Testing for heavy metals – especially arsenic and lead – should be done every five years.
