Range explained in their press comments, and again on their website, that their disclosure will “provide regulators, landowners and citizens of the Commonwealth an accounting of the highly diluted additives used at each well site, along with their classifications, volumes, dilution factors, and specific and common purposes.” Range is submitting this same information to the DEP as part of their well completion reports.
Time and again Range has explained that they believe the hydraulic fracturing process is environmentally safe. Their reasons: the Marcellus shale is generally located more than a mile below the water table and is isolated by more than three million pounds of steel and concrete casing. Also, the chemicals are “extremely” diluted, making up less than a half a percent of the total fracking fluid, they say.
True, but those small amounts add up. The average frack job uses about 4 million gallons of water. Even if only 0.14% of that is chemical additives, as listed in one of Range’s completion reports, that still represents 5600 gallons of chemical injected into the ground. Not a lot for a single well, but multiply that by the number of wells in any given area, or on any given well pad, and it adds up.
But, I digress. The point here is that Range Resources is following through with their promise to post completion wells, and you can read them at their website.
One thing you will notice is that Range is not using a long list of chemicals at each well – often five to seven products. The only problem I have with their reports is that they continue to list the only the hazardous compounds listed on MSDS, not a complete listing of chemicals in the compounds. Their friction reducer, for example, they list as containing no hazardous compounds, so they are not disclosing any of those chemicals in their drilling reports to DEP, or to the citizens of PA.
