Killer Sinkholes Could Be in Your Backyard
Chemicals play a very dangerous part in this, and should be managed and handled with the utmost care. DO NOT POUR CHEMICALS INTO THE EARTH UNLESS THEY ARE ECO-FRIENDLY. Those chemicals will drain into the land in and around your home which not only can cause sinkholes to open up but poison the plant and animal life the chemicals come into contact with.
If your home was sold to you without knowledge of a current sinkhole, you should consider contacting an attorney who can help you right away.
