CONTROVERSIES

9

(Hint: There Are a Few)

Shale Gas & Oil Controversies• Methane in water wells• Water consumption• Groundwater contamination by HF• Fracture fluid additives• Surface spills at well pads• Well blowouts• Induced seismic effects

• Flowback and produced water management• Deep injection well disposal• Atmospheric emissions• Health impacts• Methane emissions, greenhouse gas issues• Community impacts10

Community Impacts: A Partial List• Atmospheric emissions & health impacts• Increased traffic• Impacts on roads• Increased noise• Aesthetic effects – short and long term• Need for well pad setbacks

• Economic impacts (beneficial)• “Energy boom” effects• Population growth - outpacing infrastructure• Home value & rent increases• Emergency services• Health care• School populations
