PRK’s Water Wednesday: Acid Mine Drainage
August 17 @ 12:00 pm - 1:00 pm
Join Upper Potomac Riverkeeper, Brent Walls for an informative discussion on a water quality issue in the Upper Potomac: acid mine drainage. Acid mine drainage is the formation and movement of highly acidic water rich in heavy metals. This acidic water forms through the chemical reaction of surface water (rainwater, snowmelt, pond water) and shallow subsurface water with rocks that contain sulfur-bearing minerals, resulting in sulfuric acid. Heavy metals can be leached from rocks that come in contact with the acid, a process that may be substantially enhanced by bacterial action. The resulting fluids may be highly toxic and, when mixed with groundwater, surface water and soil, may have harmful effects on humans, animals and plants.
Spend an informative hour with Brent learning about the issue locally and our work in identifying locations for state implemented projects. Plus, there will be plenty of time at the end for any questions that you might have about acid mine drainage in the Upper Potomac.
