Well Water

Generally speaking private well owners are unaware of the risks associated with their water supply and many are under the assumption that they are consuming 'pure' water because it originates from groundwater. All well owners should check their wells to ensure their health is not at risk. This includes checking that:

  1. There aren’t any sources of pollution entering their well
  2. Testing the well water at least once a year
  3. Disinfection kills all E. coli including VTEC

The EPA can provide easy to use information on its website explaining what well owners should do to protect their health. More details can be found on their website at
