Distance: a Critical Aspect for Impact of Hydraulic Fracturing

by Alex Frumkin

Hydraulic fracturing is the process used to access than one-half o the U.S.’ natural gas supply and is rapidly changing the energy supplies in the United States. The popularity of unconventional drilling is increasing over the past decade, and scientists are continuing to analyze the environmental impacts of hydraulic fracturing. While public concerns are encouraging scientists to continue to evaluate the possible adverse effects related to hydraulic fracturing, Ming et al. (2014) focus on understanding the current research of these environmental impacts within a spatial content. The authors set out to better understand what the environmental impacts related to how close an area or home is to an active fracking well. They find that there are five key areas that are more likely to be impacted due to proximity to a gas well. These five areas are that the closer drinking and groundwater are to a fracking site the more likely the water is to be contaminated, that residents living nearest to fracking wells will experience higher human health risks, high density gas emissions are detected, small earthquakes are more frequent and common near a fracking well, and that there are changes to the landscape characteristics. These assessments are imperative for better understanding the impacts of hydraulic fracturing on both the environment and on human’s health. Continue reading
