Re "No Evidence that fracking leads to quakes" (Forum, March 30): Western States Petroleum Association President Catherine Reheis-Boyd misrepresented what Dr. Mark Zoback said about fracking problems.
In written testimony to the U.S. Senate, Zoback listed the earthquakes stemming from the injection of fracking waste water. Reheis-Boyd also ignores that he has described the minor slow slip observable tectonic tremors that are cumulatively derived from the fracturing done along the deep lying pipe.
The senate advisory committee he served on listed the problems with fracking: surface contamination from spills, impacts on residents, air pollution, effect on well water, scare water supplies in the west, methane leakage and flaring which offsets the benefits of natural gas and earthquakes triggered by the injection of flow-back water.
The committee supported tracking but gave 20 solutions which should be required of drillers. Too bad she didn't list the recommendations.
