Voters in Youngstown today will decide whether to ban fracking in a city where disposal of fracking wastewater led to earthquakes and groundwater contamination.The measure prohibits fracking inside city limits. Youngstown city council put the proposal on the ballot in February after an anti-fracking group collected the necessary petition signatures. Officials have questioned whether the ban could be enforced because drilling in Ohio is regulated by the state, not cities. Activists supporting the proposal disagree.
