Re "Panel OKs fracking regulator" (Capitol & California, Jan. 10): Newspaper reporters describe fracking firing a mix of chemicals, water and sand deep underground as if that was all there is to it. To frack a well, the operator must fire a propellant into the perforated length of an underground tube which, when the propellant explodes, sends out shock waves that loosen the gas and oil from shale rock.
The propellant has the nature of a rocket and frequently uses variations of rocket fuel which contain the carcinogen perchlorate. This, plus the issue of promoting seismic activity, is what's wrong with this whole process. It's a lot meaner than you think.
