Other airborne hydrocarbons connected to fracking have been linked to health and respiratory problems. Large amounts of water are used during fracking, and this water may get contaminated and harm nearby groundwater. Fracking is also linked to increased seismic activity because of the high pressures involved.
<h3>What impact does fracking have on the environment?</h3>
Drinking water or groundwater can be contaminated by fracking chemicals or liquids. Groundwater contamination can result from liquid waste stored in waste lagoons (aquifer). Methane (or natural gas) may seep into groundwater as a result of drilling. Fracking fluids or flowback fluids may contaminate water due to leaks from well casings.
<h3>What causes groundwater contamination from fracking?</h3>
Radioactive isotopes employed as tracers in fracking fluids can contaminate groundwater. Leaks from the well casings can contaminate the water with either fracking fluids or flowback fluids.
<h3>Why is fracking such a contentious topic?</h3>
Fracking is contentious due to two factors:
- the quantity of natural resources required to complete the process, and
- probably more significantly, the potential harm to the air, water, and soil in the fracked areas.
