Did you know that roughly 97 percent of the world’s fresh water is found underground? Over 15 million homes are fitted with a well water source, providing an easily accessible source of fresh water for many individuals and families across the globe. So what should you know about well drilling in NH? Here’s a few of the most frequently asked questions about the process, and some considerations to keep in mind if you are looking to add a well water source to your property.
What exactly is a drilled well?
A drilled well is a hole drilled into the ground, and is used to extract fresh water from underground aquifers. Modern methods of drilling utilize long drill shafts, which are capable of producing much longer and narrower shafts than previous and outdated methods.
Where’s the best place to drill?
After determining a geological location of an underground aquifer, there are some additional considerations to keep in mind before drilling can happen. You want to be sure the well will be located away from possible contamination sources such as septic systems, water disposal lines, or animal feedlots. Additionally, the well must be at least five feet away from any building structure. The aquifer must contain a sufficient water supply near the surface that can be accessed without the interference of dense rock and stone materials.
How is the well water protected?
Once the hole is drilled to the appropriate depth, a tube casing is inserted to protect the water supply from contamination and the potential of collapse. Screens are then inserted into the casing to filter out rocks, soil, and additional contaminants. The top is fitted with a sanitary seal to prevent the possibility of contamination or debris from entering the well and the resulting water supply in the home.
