Spring is here and that means it is time to conduct a private well maintenance check. Winter can be especially hard on outdoor systems, surfaces and landscaping that are subject to the elements. Getting in the habit of inspecting and maintaining your well system in the spring and the fall is a good habit to get into. It will help ensure everything operates efficiently and can potentially save you from shelling out money for costly repairs.

Inspection

Begin by inspecting your wellhead and area around it. The ground around your wellhead needs to slope away from it to aid in shedding water and potential contaminants away from your well. Also, make sure that there are no areas that will retain stagnant water near the wellhead and that there are no empty voids in the earth right up around the well casing. Remove close-by trees or plants with deep roots that can cause destruction to the well, water lines running from it or the electric running to it. Your inspection should also include checking that the vent screen is in place, electrical conduit, above ground casing and well cap are all intact and secure. Check all hydrants and faucets to make sure none are leaking; properly fix if necessary. Contact a licensed water well contractor to assist with any damage or issues that you find.

Runoff

Assess and divert precipitation runoff from rooflines, hard surface areas and landscaping so that it does not run toward your well as runoff can carry contaminants to your well, and potentially contaminate your water supply. Follow manufacturer’s directions of how you use, store and dispose of products like paint, solvents, oil, cleaners, wood preservatives, batteries and adhesives, as well as pesticides and fertilizers which can put your drinking water at risk of contamination through runoff.

System & Equipment

For water equipment, review recommended maintenance procedures and filter/media replacement. This includes: water softeners, filtration systems, and water heaters. At a minimum, flush out your hot water heater annually to help eliminate bacterial growth. Whenever shocking your well, empty and fill the water heater in addition to all your water lines with the chlorinated water, allowing it to have sufficient contact time within your well system for maximum effectiveness, and then flushing it. See NebGuide G1761 for detailed information on Shock Chlorination:

Testing

Finally, test for nitrates & coliform bacteria annually, as well as any other contaminants of concern in your area. Contact your local Natural Resource District, Health Department and a representative from a nearby community water system to inquire about the water quality in your area.
