Both natural and human activities can contaminate private wells. Fluoride, radon, arsenic, nitrate, and nitrate are some of the most common naturally occurring contaminants in private wells. The decay of uranium produces radon, a radioactive gas. Rocks and soil contain arsenic naturally. Animal manure or fertilizer runoff can cause nitrate buildup. Lastly, added fluoride to drinking water supplies can improve dental health or occur naturally in water supplies.

The most common human-related contaminant is bacteria from sewage lines or septic systems, which may enter the well through cracks in the casing or through other problems with the well construction. Contamination can also occur if the well was drilled using a contaminated drilling fluid or if wastewater seeps into your well system during heavy rains or flooding events.

If you suspect that your well has been contaminated, don’t drink or use the water until you have it tested. If there is contamination in your well, it’s likely that all of your water sources are contaminated.

There are two ways for private well owners to protect their drinking water quality:

Test your water regularly for bacteria, nitrates, arsenic and fluoride with a home test kit, then correct any problems immediately;

Have your well inspected annually by a certified water tester who will test for bacterial contamination.
