If you have a water well on your property that is no longer being used, then some states dictate that you plug or fill in the well so it does not become a safety hazard. Abandoned wells can also become direct points of contamination where foreign materials enter the ground and the water through the well. Plugging of a well must be completed in a proper manner. There are a few different methods that can be used to do so. Keep reading to learn about your options.
Cap The Well
The first option to plug an abandoned or unused well is to cap it. This is the simplest solution and the one that is chosen most often. A well cap is a plastic or metal covering that completely covers and closes off the top part of the well in a watertight manner. In most cases, the cap is welded in place, tightened with the assistance of threads, or bolted down in place. All of these methods create the watertight closure that creates a seal and not merely a cap, even though this is simply referred to as capping in most cases.
According to many state laws where well plugging is required, the cap must be secured by a professional. This ensures the sealing, and the professional will typically choose the best cap for the location, depth, and condition of the well on your property. It will often cost between several hundred dollars and a little over one-thousand dollars to complete the process. If the cost is too high for your budget, there are some grant programs in some states that can offset the costs. Start with your local town or county governmental agency to learn more about the financial services available to you.
Fill In The Well
If you have a relatively narrow or shallow well, then it may make more sense to fill it in instead of capping it. While this may seem simple, you cannot just through some clean fill in the well and call it a day. The well needs to be filled in with an appropriate material that will continue to protect the groundwater from contaminants. A few appropriate materials include clay that is either a soil mixture or a compacted variety. Cement, bentonite, and grout are a few options too. Basically, the material needs to be organic, safe, dense, and hard.
Before the well is filled in, pumps, debris, and plumbing parts will need to be removed. A professional can assist with this and also with the addition of the fill material. For more information or advice, contact a business such as Advanced Water Well Technologies.
