Four Factors To Help You Decide Where To Drill Your Well

An experienced well drilling contractor may be able to give you advice on good well locations, but even before you hire a drilling contractor, you can give some thought to exactly where on your property you’ll locate the well. There are many factors that influence what makes a perfect spot for a well. Use these four points to help you narrow it down.

1. Distance from potential contaminants

One of the first things to consider is where not to put your well. You shouldn’t put it close to a potential source of groundwater contamination, such as a feed lot, a silo, a cesspool, or a septic tank. Other things to stay away from include:

  • Outhouses
  • Landfills
  • Property boundaries 
  • Roads

2. Relative elevation

The easiest spot to sink a well is the lowest spot on your property because that’s likely to be the spot closest to the groundwater. However, sinking a well at the lowest spot has certain disadvantages (such as that gravity tends to pool contaminated storm runoff there, so it’ll be impossible to keep the well clean). Because of this, you should instead choose another lowish point, one that doesn’t have surface water already and doesn’t collect runoff. If you do have surface water on your property (such as a river), it may be a safe bet to sink your well just a few meters from the river, since that spot is likely to have plenty of underground water near the surface.

3. Type and composition of soil

Some types of soil are easier to sink a well in than others are, and some produce more water than others. If you have an especially unfriendly type of soil, such as sand, you may need to take steps to adapt the well to the situation. If you have multiple types of soil substrate on your property, consult with your well drilling contractor about which type will work best for your well.

4. Plants nearby

If you live in a dry climate and don’t have a river on your property, one of the ways to determine if water is near the surface is to look for increased amounts of plant growth, especially large plants such as water-loving trees. Some of the trees you should look for include cottonwood trees and willow trees.

These four aspects of well location will help you narrow down the possible locations for your well and give you a few ideas for a likely spot that may yield a high-performing well for years to come. For more information, contact GeoTek Alaska Inc or a similar company.
