It is recommended for private water well owners to test their water every 1-3 years for bacteria and nitrates.
More frequent testing should be considered if:
- Change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination source
- Well has a history of bacterial contamination
Septic system has recently malfunctioned
- Family members or house guests have recurrent incidents of gastrointestinal illness
- An infant is living in the home
- To monitor the efficiency and performance of home water treatment equipment
