History of hydraulic fracturing Low volume vertical hydraulic fracturing is a technology used in more than 1 million wells in the U.S. since the 1940s to help produce oil and natural gas. It involves pumping 50,000 to 100,00 gallons of a water-chemical-sand mixture into underground rock layers where the oil or gas is trapped. The fracking fluid under intense pressure creates tiny fissures in the reservoir rock. The sand and chemicals hold open the fissures, allowing the oil or gas to escape and flow back up the well, along with fracking fluids and deep earth compounds.
History of hydraulic fracturing Since 2002 a new technology has developed, combining deep horizontal drilling with hydraulic fracturing, called horizontal slickwater hydraulic fracturing and know as “fracking” today. This technique began in Michigan around 2010. This method has used from 5 to 21 million gallons of freshwater per well in Michigan (future wells could go much higher) mixed with chemicals and sand pumped up to two miles or more into the Earth then turned horizontal for two miles or more. The mechanics are the same as low volume but the community and environmental impacts and potential problems are magnified.

University of Michigan StudyGraham Sustainability Institute(with state and industry participation) Hydrological connectivity can lead to contamination impact distant from, as well as close to drilling sites. Fracking wastewater often contaminated with heavy metals and radioactive materials. Compaction of land at site causes change in hydrology. Impact of large number of truck & equipment; traffic, light, noise, diesel exhaust, oil/gas fumes… Did not distinguish enviro impact between low and high volume wells Most common remark in the report: too little Michigan-specific data to make conclusions/risk assessments. This shows the claim of no contamination in Michigan has no data to support it, because it was never collected.

Near A Well? • United States Environmental Protection Agency Region III (January 19, 2012) – “Methane contamination was detected in private wells thereafter in concentrations exceeding those previously found.” • “Other chemicals found in produced water include VOCs, metals and radio nuclides… The Petroleum Institute estimates that nearly eight barrels of water are produced for every barrel of oil…Methane and fracking chemicals can also migrate into shallow aquifers used for drinking water wells…” USHHS, Agency for Toxic Substances and Disease Registry, CO Dept Health & Env. • Scientific American – “High Levels of Arsenic Found in Groundwater Near Fracking Sites” • Duke University’s Daniel Rozell and Sheldon Reaven – an individual fracking well releases at least 200 m^3 of contaminated fluids. • “Greene County shale well continues burning” Pittsburgh Post-Gazette Feb. 12, 2013 “The heat from the blaze -- which caused a tanker truck on site full of propane gas to explode -- was so intense that first responders from local fire departments had to pull back rather than risk injury.” The fire burned for a week, killing one worker.

The Fracking process Natural gas (methane) leakage in extraction/supply chain is 10-15%. Leakage means natural gas (25 times as heat retaining as carbon) is more climate change active than coal. Oil company claim: no cases of water contamination in MI. Reality: no baseline testing or even post drilling testing on 90% of wells to know if contamination has occurred. UM study said not enough Michigan-specific data. Sustainability demands 30+ year view in policy analysis, Triple Bottom Line. Fracking and fossil fuels fail those tests, for local pollution and global climate.

THE WALL STREET JOURNAL Exxon CEO Joins Suit Citing Fracking Concerns By Daniel Gilbert Feb. 20, 2014 Exxon CEO Rex Tillerson “has joined a lawsuit that cites fracking’s consequences in order to block the construction of a fracking water tower next to his and his wife’s Texas home.” “traffic with heavy trucks on FM 407, creating a noise nuisance and traffic hazards,” the suit says. “A lawyer representing him said his concern is about the devaluation of his property…” “When he is acting as Exxon CEO, not a homeowner, Tillerson has lashed out at fracking critics and proponents of regulation.” Also saying “the risks are very manageable.” So why not by his house? US Bureau of Economic Research: Fracking can have a small to moderate positive property value impact if a home has water department hookup, but it can have a 20-30% negative property value impact if a home has a private well.
We need safer alternatives Water Resources Commissioner’s office is developing a demonstration project to install a power generating turbine in a sewer/stormwater line. The WRC is looking at this and other renewable energy projects to reduce our impact on the power grid. Farmington Hills City Hall installed geothermal heating and solar panels, reducing their gas bill from $30,000 annually to zero. Other local public and private buildings have also done the same, and more are being converted daily. Net Zero energy buildings, making as much energy as they use, are the future. Nationally, 13,000 megawatts of wind power were built in 2013, we installed 7,000 megawatts of solar power in 2012 and 10,000 in just the first 9 months of 2013.
We need safer alternatives Cost of solar panels has fallen 60% since 2010. Solar leasing/purchasing agreements making solar installations more affordable and common for businesses/homeowners.
