Range Resources Corporation is a natural gas exploration and production company, the headquartered is in Fort Worth, Texas.

In 1999, the company formed a 50-50 joint venture with FirstEnergy called Great Lakes Energy Partners LLC to own properties in the Appalachian Basin.

[10] In 2010, the company announced that it would list on its website the chemicals, including their volume, concentration and purpose, used in its each well completed via hydraulic fracturing.

Residents complained of black running water that corroded faucets and household machinery, showers smelling of "rotten eggs" (hydrogen sulfide) and diarrhea, "mysterious stomach pains", extreme fatigue or anemia.

Medical tests of residents complaining of headaches, nosebleeds and the inability to concentrate showed elevated blood levels of organic solvents and heavy metals such as toluene and arsenic.

[13][14] According to a letter from the company to a complainant dated January 14, 2011, "On November 10, 2010, you voluntarily supplied Range Resources with lab results from both your dog and horse veterinarians.

Range maintained that it was likely caused by "decayed vegetation that gave off gas", having attributed previous complaints of malodor to harmless anaerobic bacteria that grew near its fluid compressor stations.

However chemical tests of the area later "revealed the presence of acetone, toluene, benzene, phenol, arsenic, barium, heavy metals and methane".

The bulk was $141,175 levied for a fracking fluid spill that killed aquatic life in Brush Creek in Washington County, Pennsylvania, which is protected by the state as a "high-quality waterway" according to the Pittsburgh Business Times.

In September 2014, the company was ordered to pay a $4.15 million penalty to settle violations related to 6 Marcellus Shale gas drilling and fracking wastewater impoundments in Washington County that contaminated soil and groundwater.

The EPA said that natural gas drilling by the company has contributed to the contamination of at least 2 residential drinking water wells in the county and ordered it to step in immediately.

[23] In 2011, as part of an effort to reassure the public of its activities, the company started a campaign, "My Range Resources" which depict "ordinary people... who have benefited from allowing drilling on their land".

The ad campaign includes, in the words of journalist Bob Myers, "real Pennsylvanians talking earnestly about the wonderful experiences they’ve had with Range Resources".

Reg Henry of the Pittsburgh Post-Gazette thought "the whole promotion was skin crawling... but now I read MyRangeResources and I think: How cute is that for a gas drilling company?

[28] As part of the settlement, the family members agreed to a gag order preventing them from talking about hydraulic fracking for the rest of their lives.

"Range has never, at any time, had the intention of seeking to hold a minor child legally accountable for a breach of that provision of the settlement agreement."

[31][32] In 2013, the company settled for $87.5 million a class-action lawsuit alleging royalty underpayments on sales of natural gas in Oklahoma.
