Injection wells are now being permitted in Pennsylvania. Injection wells are installed to store fracking fluids from gas well drilling. In other areas of the country, for example, Oklahoma, injection wells have been linked to earthquakes, seismic activity, and underground pollution of water. I guess injection wells are going to be increasing in number. It is truly troubling that, added to more and more pipelines and compressor stations, we must face the consequences of all these threats to our environment and our health.
