What you should know about Drinking Water
Well water contaminants can cause water to taste bad, and are linked to a wide variety of health issues.
As the owner of a private well, you are ultimately responsible for the quality of your drinking water. Unfortunately, even very small concentrations of contaminants like lead, arsenic, nitrates or pesticides can compromise drinking water quality, causing health problems such as kidney and liver damage, learning disabilities and nervous system damage in those with compromised immune systems. There are more than 84,000 chemicals registered for use in the US*, an untold number of which might be in your water. Contaminants and toxins are not detectable in drinking water, but can put the health of your family at risk.
