Key Takeaways
- In Dimock, Pennsylvania, private wells tested positive for methane at levels up to 28 milligrams per liter, exceeding the state's action level of 10 mg/L
- USGS sampling in Pavillion, Wyoming detected benzene in two monitoring wells at concentrations of 3.6 and 6.8 micrograms per liter, above the EPA drinking water maximum contaminant level of 5 ug/L
- In Bainbridge Township, Ohio, methane concentrations in a homeowner's well reached 3,500 micrograms per liter post-fracking, 35 times the baseline
- Pennsylvania DEP found 243 cases of stray gas migration impacting water supplies from 2008-2014
- Duke University study: 6.2% of drinking water wells within 3km of fracking had methane >10 mg/L vs 1.3% farther away
- 7.1% of 426 wells in Colorado's Wattenberg field showed hydraulic fracturing fluids or additives
- Baltimore study: birth defects 50% higher in areas with dense fracking activity
- Yale study: PA residents within 1km of fracking had 2.24 odds ratio for asthma exacerbations
- Columbia University: preterm births increased 48% in fracking counties
- In Mammoth CA, fish in streams showed DNA damage from fracking chemicals in water
- Sugar Run PA: 13 wells contaminated with methane, barium, and manganese after fracking
- Leroy Township PA: gas migration caused explosive well conditions in 7 homes
- EPA finalized 2016 assessment: fracking can contaminate water but lacks comprehensive data
- PA DEP issued 2,973 violations for water contamination at fracking sites 2008-2018
- Texas RRC: 7,236 fracking-related spills reported 2010-2020, 25% impacting groundwater
Multiple cases show fracking chemicals contaminating drinking water, harming health.
