If you are like most people, as long as water comes out of the tap, you don’t give it much thought. If your water is supplied by a water company, stringent testing is required by law, and you will periodically receive results of the testing. If you are one of the 40% of Connecticut residents who has a private well, the last time you had that water tested was likely when it was built (you can’t move in unless your well water meets certain criteria), or when you purchased it (if you have a mortgage, the bank will often require testing to make sure you have a safe water supply).
Older homes had shallow wells which drew from groundwater close to the surface. These wells are vulnerable to contamination from surface sources. Newer homes have wells that are drilled into the bedrock, and may be hundreds of feet deep. However, even deep wells can become contaminated from surface sources such as nearby septic systems, road salt, leaks from gas stations, or agricultural activities. Other contaminants such as radon, uranium and arsenic are naturally occurring in some parts of Connecticut.
The best way to protect you and your family from possible contamination is to test your water at one of the state’s certified testing labs. For an extra fee they will come to your home and collect the sample for you, or they will give you instructions on how to collect the sample. The Connecticut Department of Public Health has more information about private well testing. A basic potability test will cover a variety of contaminants including nitrate, sodium, chloride, and bacteria. If you leave near an agricultural area, you may also want to test for pesticides.
It is easy to take our water for granted. Keep your family safe and get your water tested!
