- Groundwater contamination: Fracking liquids or chemicals can contaminate drinking water or
groundwater. Liquid waste stored in waste lagoons can leach into groundwater (aquifer). Drilling can allow methane (or natural gas) to seep into groundwater.
- Excessive water use or consumption: Considerable amounts of water are used in the fracking process. This can result in overdrafts of aquifers. Water demands for the fracking process
compete with water demands for drinking or irrigation (agriculture).
- Benefits of natural gas (must be environmental, not economic) include the following:Fewer SOx are produced, resulting in less acid rain. Fewer NOx are produced, resulting in less acid rain and less photochemical smog. Less Hg is released. Harmful mining techniques are avoided; for example, no strip mining or mountaintop removal is required.
- Habitat fragmentation/destruction can occur from setting up the drilling site or from building
- Earthquakes can result from the drilling/fracking process.
- Methane can leak (into the atmosphere) during the process, resulting in an increase of
greenhouse gases.
- Subsidence of the land can occur once fracking fluids are removed.
- Spent nuclear waste (fuel): a storage facility does not exist for high-level waste; waste has to be stored for 10 half-lives in order to be considered safe.
- Thermal pollution from cooling operations (impacting surface waters).
- Nuclear accidents/plant failures: release of radioactive substances, resulting in contamination of soil, water, air, and living organisms.
- Uranium is a nonrenewable resource.
