Tips for testing your well


Well water can be contaminated but still look, smell and taste fine. One in 10 Maine wells contains highs levels of arsenic.

Test private well water:

— Every year for bacteria, nitrates and nitrites.

— Every three to five years for arsenic, radon, uranium, lead and fluoride.

Also test if:

— You’re expecting a baby.

— Your water changes in color, taste or smell.

— Test for bacteria if you introduce new parts, such as a new pump, pipes or water softener, or a well runs dry and comes back.

— You put in a water treatment system to address a problem. Test the treated water each year for that problem.

If elevated levels of arsenic are detected, use bottled water for drinking and cooking, or install a water filtration system.
