Well Water Contamination in New England

Posted on March 09, 2017

Having a private well can be wonderful, but it means you have sole responsibility for your water quality. This can be as simple as regularly testing your water (at least once a year for some contaminants, like nitrates and bacteria) to ensure its safety. However, it’s not at all uncommon for well water to be tested when the well is installed, but then never again unless there’s a noticeable change in the water’s taste, appearance, or smell. Knowing what you should be testing for is the first challenge, since the potential for water contaminants can vary from place to place. In the New England area, these are the primary naturally-occurring contaminants encountered:

  • Bacteria
  • Iron
  • Manganese
  • Radon
  • Arsenic
  • Uranium

Ironically, iron and manganese are less likely to be present at levels that could be damaging to your health, and yet they’re more likely to leave clues that they’re present. That’s because iron and manganese can both cause staining to clothes and fixtures. As for the rest – bacteria, radon, arsenic, and uranium - they don’t affect the taste, colour, or odour of your water, so knowing whether or not you have a problem is impossible without a water test.

It’s important to note that the health impacts for most (bacteria are the exception) aren’t immediate - it’s long-term consumption of the water that can develop into serious health concerns. For instance, drinking water with even low levels of arsenic over many years can lead to increased chances of lung, liver, skin, and bladder issues.

With bacteria and other microbes, the effects are likely to be felt fairly immediately – often within a day or so of drinking the CrittersGlass.jpgcontaminated water. Infections from bugs like E. coli, Cryptosporidium, Giardia, and water-borne viruses generally cause gastrointestinal symptoms, including abdominal cramps, diarrhea, nausea, and vomiting. It’s easy to dismiss these as the result of something you ate or even a flu bug, though.. But if you don’t consider the possibility that it was the water, you run the risk of it happening over and over again. With a simple water test, you can confirm whether or not your well water is the problem and then take steps to fix it.   

Other contaminants that can be found in the New England states include pesticides, nitrates, or volatile organic compounds (VOCs) such as benzene. These are the result of human activities and may be more localized.

Once you have a current water test, speak with a water treatment professional for help interpreting the results and determining which water treatment equipment can keep your water safe. Or check out our Help Me Choose tool
