HRSD SWIFT, Challenges and Strategies Using Reuse Water to Recharge the Potomac Aquifer

Presentation Time: 11:00 AM - 11:25 AM

This session focuses on the HRSD Sustainable Initiative for Tomorrow’s (SWIFT) strategy to deliver highly treated SWIFT Water® into the Potomac aquifer, addressing several physical and geochemical challenges in the well and aquifer. Well design and construction are critical to obtaining, and maintaining, the highest capacity possible. Geochemical concerns include clay destabilization, due to ionic strengths differences between recharge water and native groundwater and arsenic mobilization from redox changes. A combination of well design, construction, aquifer conditioning and recharge water chemistry adjustments are required to maximize capacity, minimize well clogging and clay fragmentation and immobilize metals to meet operational and regulatory goals.
