Impact/Purpose:
This webinar will inform EPA staff, EPA policymakers, and external stakeholders of potential issues and tools that can be used for the implementation and long-term management of EAR and GI systems.
Description:
Enhanced Aquifer Recovery (EAR) and Green Infrastructure (GI) convey runoff from stormwater and treated wastewater into the subsurface for storage, potential reuse, and augment water supplies. Potential impacts to groundwater quality from the use of EAR and GI are poorly understood. This research will examine any potential changes to groundwater quality. In addition, the use of EAR and GI in karst geology has had limited study. The goals of this EPA research is to understand the fate and transport of contaminants as well as potential impacts to water quality EAR and GI could have. Another goal of this research effort is to use and demonstrate the use of geophysical tools to understand the movement of water in an EAR system in a karst environment. The presentation will present preliminary findings from this research.
