Hydraulic Fracturing: Risks and Management

23 Aug 2024

  • Hydraulic fracturing, a technique used in oil and gas production, has faced strong opposition from environmental groups in the several decades since the practice came into widespread use. 
  • Opponents of hydraulic fracturing assert that the process poses innumerable risks to the environment and human health—and have lobbied governments to impose moratoria and outright ban hydraulic fracturing entirely.
  • Since 2014 Fraser Institute researchers have conducted periodic surveys of the literature assessing the environmental and health risks of hydraulic fracturing. Generally, they found that while the risks posited by opponents of hydraulic fracturing are real, they are neither high nor overly frequent and could be mitigated with various technological changes and changes to the hydraulic fracturing practice. 
  • In 2014, we reviewed nine high-profile studies and reviews of the impacts of hydraulic fracturing; an additional five studies were added in 2015; and nine additional studies were incorporated in 2020. Again, we concluded that hydraulic fracturing should continue as we improve the current system of governmental and industry self-regulation (Green, 2014: iii–iv).
  • In this update, six high-level reviews or summary publications shedding additional light on the risks of hydraulic fracturing have been included—particularly pertaining to seismicity and water overuse/contamination, but also several studies examining direct effects on human health. 
  • As with previous reviews, this one finds increased knowledge about the risks of hydraulic fracturing continues to accumulate, with indications that some of the risks—increased seismicity and impacts to groundwater—may warrant greater mitigation efforts than previously thought necessary. 
  • Monitoring of air and water quality as well as induced seismicity in areas engaging in hydraulic fracturing may need to be increased, and exposure notification systems strengthened to ensure that nearby populations are enabled to manage their risk exposures from hydraulic fracturing operations.
