What health considerations are there?

Water Quality

There could be some localized water quality impacts as a result of seismic exploration activities. As mentioned above, the creation of survey lines or vehicle track marks can cause surface disturbance. If not restored, they can lead to erosion and runoff into waterways. Earthworks, a nonprofit advocacy organization working to protect communities and the environment from the adverse impacts of mineral and energy development, indicates a few considerations for private well owners with regard to seismic testing. For example, private well water could be affected if the shot holes reach the water table and are not properly plugged. 1 In this case, the shot holes could provide a pathway for contaminants to the groundwater supplying the wells. Earthworks also notes that underground seismic explosions could also impact subsurface water flow and pressure, potentially reducing well water supply. 2
