The results of the project will help provide a better understanding of the potential risks of groundwater contamination that might be linked to stormwater infiltration in urban watersheds associated with the use of dry wells with low impact development (LID) features. Results should provide reliable scientific information which regulators can use to determine appropriate guidelines for dry wells in the Sacramento region and throughout the State of California. The data will also determine the value of using dry well to manage localized flooding and as a tool to increase groundwater recharge capacity.
The results of the study should be useful to these audiences:
- The State Water Resources Control Board for the development of the statewide Groundwater Quality Strategy to include guidelines for use of dry wells.
- US EPA Region 9 related to the Groundwater Injection Well Program.
- The California Conference of Directors of Environmental Health, Water Well Technical Advisory Committee, related to their development of dry well standards for incorporation into California Department of Water Resources Bulletin No. 74 (Water Well Standards).
- Local health and environmental management departments that oversee drinking water quality.
- Water supply agencies interested in protecting groundwater quality and promoting groundwater recharge.
- Stormwater program managers and members of the development community looking for cost-effective LID solutions.
- Flood control managers looking for alternatives to reduce localized flooding and to implement LID practices.
In addition, this project will also provide guidance for on-site evaluation and selection, design, construction, and monitoring of dry wells that will minimize risk to groundwater quality.
Project results will be posted on this page as information becomes available.
