Protect Your Well

Know exactly where your well is located on your property, and keep well construction and maintenance records.  Remember to disinfect any equipment that will be used inside your well prior to use.

Keep potential contamination sources , such as fuel and chemical storage, septic tanks, or livestock away from your well.  To better understand how a contaminant source can impact your well water, review our Groundwater Contamination fact sheet

Know exactly where your septic system is located on your property, maintain it regularly, and keep maintenance records.

A big part of protecting your well from contamination is keeping surface water, which often carries contaminants, from entering your well.

  • To keep water from ponding around your well, make sure the soil slopes away from the well.
  • If you hear water freefalling into the well, find out where the water is entering your well.

Maintain the integrity of your water well. 

  • Check visible casing, sanitary seal and well cap for damage regularly.  Repair or replace missing or cracked components with commercially manufactured parts immediately. 
  • All vents should be covered with a fine mesh screen to prevent animals and debris from getting into the vent.

Properly plug and seal any unused or abandoned wells.

If you do need to drill a new well, be sure to review the DEQ fact sheet on locating new wells before you begin.

DEQ recommends sampling your well water annually. Water well owners in areas of potential oil and gas development should test for additional constituents.
