Impacts of fracking include
nasty-shy [4]

Answer:

D is the answer

Explanation:

Hydraulic facturing, aka fracking, uses toxic chemicals above some regulations which may lead to a leak into water supplies and therefore contaminate it.

It has not much to do with coal, more to do with oil and natural gases

Because of fracking now making it accessible to reach sources in vast number that were previously unacessible, it leads to decreases in gas prices

Hope this helps :)
