There's much debate about whether shale gas "fracking" (i.e. hydraulic fracturing) poses a risk to our freshwater resources. However, alongside the fact that the water demands of fracking are relatively small compared to other uses, the available scientific evidence actually paints a fairly optimistic view of the situation. Thus far, no causal link between drilling activity and water pollution has been found $$-$$ despite researchers scrutinizing some pretty extensive data.
