Planning Your Water Well
(NAPSI)—To best ensure you have an adequate supply of good-quality water, it’s important to do some planning before the work begins, according to the National Ground Water Association (NGWA).
This is true whether you’re having a new water well installed or replacing an old well. For example, when building a new house, it’s advisable to plan the water supply before starting construction, if possible. Some owners of newly built houses have sadly discovered that the only property left on which to drill a well resulted in poorly producing wells.
For the person seeking a replacement well, the challenge is similar—finding a place on the property where an adequate water supply can be accessed.
In both cases, the location of the well can be critical to water quality. Your drilling contractor will likely have enough experience with the area to know about any naturally occurring or man-made contamination in the groundwater. Also, the county health department may be able to tell you about any health risks related to the groundwater.
The actual location of your well will often be determined by factors other than geology. Land surface features such as steep slopes and poorly drained areas are also considerations. Whenever possible, wells should be at higher elevations than the surrounding areas to decrease the potential for contamination via water pooling around the wellhead.
Also, the well should be located so that it is accessible for cleaning, treatment, repair, testing, inspection and other activities that may be necessary over time.
Location, Location, Location
Because of the dangers resulting from proximity of the well to sources of surface contamination, many governments have established minimum distances between the wellhead and potential contamination threats. In general, these are:
• Cesspool (receiving raw sewage), 200 ft.
• Pit, privy, filter bed, 50 ft.
• Septic tank, tile sewer, foundation drain, 50 ft.
• Iron sewer with approved mechanical joints, 10 ft.
• Pump house floor drain, 2 ft.
• Property boundary, 5 ft.
• Outer boundary of any road, 20 ft.
• Landfill, garbage dump, 200 ft.
Here are some additional guidelines from NGWA:
• The immediate area surrounding the well should be free of debris, dirt, chemicals, fuels or any other potential contamination source.
• Surface water should in no way interact with the well area.
• The well should be a safe distance from the natural flow of groundwater from under animal pens, pastures and feeding areas.
• Any growth of weeds, trees, shrubs or grasses with root systems within 10 feet of the well should be removed.
• Ensure the wellhead is not in a roadway or driveway; if it is within 24 inches of the roadway or driveway, it should be properly marked to avoid being hit by vehicles.
• The wellhead should be at an elevation above any surrounding contamination sources.
• The topography directly surrounding the wellhead should slope away from the casing to facilitate surface runoff away from the well.

Proper planning is important for your dream home—especially if you wish it to include a well.
