How often should I test my well water.
The National Groundwater Association recommends well owners test the water:
- Annually for bacteria, nitrates/nitrites, and any contaminants of local concern
- More frequently than once a year if there is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap or a new contamination source
- If family members or house guests have recurrent incidents of gastrointestinal illness
- If an infant is living in the home
- To monitor the efficiency and performance of home water treatment equipment.
You should also check with your local health or environmental health department for recommendations regarding the type and frequency of testing specific to your location.
The presence of coliform bacteria is a possible indicator of a well's susceptibility to contamination from animal wastes. E. coli is bacteria that originates from wastes such as those found in sewage, and it can result in severe illness. Its presence suggests a contamination source such as a poor performing home septic system in the vicinity of the well that should be repaired or removed by a qualified septic system contractor.
In the vast majority of cases, nitrates come from farm or industrial contamination, or septic systems, and they can be dangerous to your health. Nitrates from fertilizers and septic wastes could be an indication of a local source of contamination or regionally contaminated ground water.
Arsenic is an example of water quality concerns that can be present on either a local or regional basis. It can can be naturally occurring in an aquifer. Arsenic is a semi metallic element that occurs in rocks and soils-and water that comes into contact with these rocks and soils.
