Most private wells serving a single family do not require frequent water testing, assuming the initial well water quality is good. However, periodic water quality testing is a good idea – at least once a year and more frequently if problems arise. Changes in well water quality can occur suddenly or gradually. Sudden changes are usually the result of something nearby, such as a new source of contamination upstream or leach field activities downstream. Runoff from heavy rains can also cause changes in water quality. Gradual changes are more likely the result of changes in the local aquifer or well.
Some well owners choose to have their water tested more frequently, particularly if they have a new well, participate in a water quality monitoring program, have had previous water quality problems, or live in an area with known contamination issues. The frequency of water testing also should be increased if there are changes in taste, odor, or color of the water, or if there are new uses for the water (e.g., an infant in the home).
Local health departments or certified laboratories can test well water for common contaminants. The type and number of contaminants tested for depends on many factors, including the contaminant(s) of concern in the area, the well’s location and depth, the type of aquifer, and the well’s construction.
What are the consequences of not properly maintaining my well water?
If you do not properly maintain your well water, the consequences can be dire. Your water could become contaminated with bacteria or other harmful contaminants, which could make you and your family sick. In extreme cases, it could even lead to death. Additionally, your well could fail, and you would be without water. This could be especially devastating in an emergency situation. Finally, not properly maintaining your well water could void your warranty, leaving you responsible for all repairs.
Frequently Asked Questions
What are the most common well water contaminants?
Well water can contain a variety of contaminants, including metals and minerals. Iron is one of the most common contaminants.
What are the dangers of well water?
Arsenic is a common contaminant found in well water. This poison can cause cancer, heart disease and neurological problems. While arsenic isn’t found in every well, installing a whole house water filtration system can easily remove it from your water and your worries.
What can contaminate a private well?
Private wells can become contaminated by rainfall or snow melt which can wash microorganisms into the well. Leakage of waste from underground storage tanks and effluent from septic leach fields can also contaminate water wells.
What lurks in well water and how can you protect yourself?
Microorganisms can be found in well water in the form of bacteria, protozoa, and cysts. These microorganisms can cause health problems such as diarrhea, respiratory infection, and skin irritation. One way to remove these types of microorganisms from well water is by filtration. However, this is not always an effective method because some microorganisms are resistant to filters. Another option is to use a reverse osmosis system to purify your water. However, this will also remove minerals and other beneficial elements from the water which may be beneficial for you.
What are the most common contaminants in water?
The most common contaminants found in water used for human consumption are: arsenic, chlorine, and fluoride.
