  •  There is absolutely no evidence (with the (1+ / 0-)
    Recommended by:

    exception of Pavillian, WY) that hydraulic fracturing and
    transport of gas from deep strata have caused the problems you identify.   Those kinds of problems are caused by failures of well cementing and blowouts at the casing cement shoes which are well construction problems occurring when such construction is not properly done.

      to imply that fracking isn't the cause, just parts of the process of fracking are at fault. Well, duh, the problems wouldn't occur if it weren't for fracking.

      Plus, there's plenty of evidence of harm, but it's not being weighed as it should be, with oil and gas lobbyists hard at work to remove as much oversight and liability as possible.

      •  The totality of all oil and gas operations are (0+ / 0-)

        not called "fracking."

        Hydraulic fracturing fluid is pressured to rock strata 7000+ ft below.   There is no way for gas to escape the strata being hydraulically fractured, particularly in a new well, in the absence of a breach of the well cement job of the surface and intermediate casings.   New casings don't have these breaches, and there is no evidence that it is impossible to conduct a casing cementing operation in an oil and gas well without a cement failure.   This means that, absent such a failure there is no physical path for gas migration from hydraulically fracktured strata for the gas migration to take place.

        A gas well that has cause methane intrusion is presumed to have had an underground blowout at the shoe of the cemented casing.   That the physical phenomenon of gas migration has occurred with gas introduced to a shallow potable water aquifer has nothing at all for a geology/hydrology/engineering based demonstration that the operation of hydraulic fracturing has caused such shallow aquifer methane migration.

    •  The federal EPA (0+ / 0-)

      is even backing off their Pavillion groundwater findings.
