- Goals: Improved water quality, enhanced environmental quality, counteract coastal saline intrusion.
- Solutions: Water purification through (partial) in-situ processes, MAR and ASR.
- Green infrastructure: subsurface environment providing natural and in-situ attenuation of contaminants, carbon and nutrient regulation, riparian buffer strips.
- Grey infrastructure: Pump-and-treat solutions, managed/enhanced in-situ soil and aquifer treatment, reactive subsurface barriers, subsurface dams, riverbank filtration, injection wells in coastal areas.
- Policy interventions: (Ground)water and soil quality standards, groundwater and soil protection policies, pollution liability regulations.
