Natural Gas and Fracking

Natural Gas and FrackingHydraulic fracturing, or fracking, is a drilling process that injects millions of gallons of water, sand and undisclosed chemicals at high pressure into horizontal wells to crack open shale rock and release natural gas. Largely unregulated, the fast-spreading gas-extraction method is enjoying an unprecedented boom, but it could also be contaminating underground water supplies.
In Alberta and British Columbia, regional authories have passed regs to allow more intensive drilling. The result: a string of record-breaking fracks.
Early last year, deep in the forests of northern British Columbia, workers for Apache Corp....
