Mays Danfoura's research uses SF State's low impact development (LID) network which includes three of the most commonly used best management practices (BMP) that have been instrumented to monitor recharge quantity and quality. Her research evaluates how the selection and design of BMPs controls recharge rates and important geochemical processes that affect many potential groundwater contaminants.


Freshwater resources in many urban environments are highly vulnerable to human pressures and climate variability and change. Impervious surfaces prevent infiltration of urban stormwater and cause localized flooding, and increase contaminants in surface runoff that often overwhelm combined stormwater-sewer flows. To address these concerns, urban stormwater managers are increasingly using low impact development (LID) site planning to maintain or replicate the predevelopment hydrologic conditions by using best management practices (BMPs) that decrease the impacts on stormwater drainage systems and help maintain surface-water quality. The selection and design of LID BMPs has traditionally focused solely on surface conditions.


Danfoura's research encourages LID planning that also considers the vulnerability of urban groundwater to stormwater contamination. Groundwater is a significant source of water for human consumption, providing about 40% of U.S. public-water supply. Groundwater is important for sustaining streams, lakes, wetlands, and ecosystems.
