Wells dig a deeper hole for our underground water March 12, 2010

Many people know the obvious problem of wells: they drain our underground water sources. People don’t usually think of other potential problems. Since most abandoned wells are not decommissioned properly, they are often partially filled or left completely open. In places that have significant amounts of soil and rock layers, this can pose a devastating problem.
The sequential layers of topsoil, subsoil, and bedrock act together to filter out many chemicals and other contaminants. Eliminating these crucial layers of filtration lets the contaminants seep directly into underground aquifers. Sometimes this occurs at abandoned sites with significant amounts of pollution, where they are not discovered until human water sources are contaminated and can no longer be used.
Abandoned mines are often found at abandoned farms and other old use sites. Many environmental agencies recommend surveying your site to determine whether you have an abandoned well on your site or not. Signs may include: damp, round impressions in the ground, cement slabs with circular metal pipe, manhole covers, pits in basements, or obsolete windmills.
