  15. Potential Environmental Impacts of Hydraulic Fracturing Amy Townsend-Small atownsendsmall@gmail.com

  16. Impacts • Groundwater depletion • Water quality impacts • Air quality impacts • Greenhouse gas emissions

  17. Impacts on Cincinnati • DIRECT environmental impacts on the Cincinnati region are unlikely • Except if wastewater is imported here for disposal Image source: ODNR Division of Oil and Gas Resources Management

  18. Impacts on Cincinnati • May have positive and/or negative economic impacts • Positive: due to increased commerce in Ohio • Negative: increased infrastructure and pollution control costs • Also: increased withdrawal and combustion of fossil fuels will negatively impact us all due to air pollution and climate change

  19. Groundwater Depletion • Each new well will require tens of millions of gallons for initial development • Will this come from surface waters (Lake Erie, Ohio River) or groundwater aquifers? Unknown • For reference: water use in Cincinnati is about 100 million gallons per day – so effects will likely be localized to fracking areas

  20. Water Pollution • Two issues: • Chemicals added to water by drilling company • Salts • Acids • Ethylene glycol (antifreeze) • Biocides and algicides • “Proprietary” chemicals • Chemicals produced by interactions with shales • Hydrocarbons (BTEX: benzenes, toluene, ethylbenzene, xylene) • Additional salts • Radioactive isotopes

  21. Water Pollution • Disposal of fracking water • Surface disposal • Deep injection • Recycling • Treat and release Image source: Journal of Petroleum Technology

  22. Atmospheric impacts • Ozone and smog from diesel-powered equipment • Methane release • Explosive in high concentrations • Greenhouse gas (25 x carbon dioxide) • “Fugitive” methane emissions may result in a higher overall carbon footprint for fracking than for coal • Noise pollution
