Investigating the use of green infrastructure to improve water quality and expand usable water supplies
The intent of this scoping study is to compile existing design and performance information on GI projects that have been developed by Reclamation (pilot-, demonstration-, and full-scale), identify areas for potential enhancements based on "lessons learned" from these existing facilities, and identify potential locations where GI can be used to enhance the suitability for use, and thus increase the availability of potential water supplies.
Need and Benefit
This scoping proposal addresses the need to expand water availability for multipurpose objectives through conjunctive reuse practices. "Green infrastructure" (GI), such as constructed wetlands and soil/aquifer treatment, is an emerging tool to compliment advanced water treatment technologies. GI involves passive, naturally occurring biogeochemical processes such as biodegradation, plant uptake, photolysis, volatilization, sorption, and precipitation, for water quality improvement and environmental protection.
