Stormwater Management and Green Infrastructure Research
For many cities, stormwater management remains a significant challenge. Treatment of stormwater related pollutants may be required to minimize the impact of contaminants on the watershed. In some cases, treatment is not possible when surges in stormwater overwhelm systems that convey combined sewage and stormwater. This can result in direct discharge of untreated human, commercial, and industrial wastewater into surface waters. EPA's research is helping communities improve water quality, manage water quantity, and reduce flood frequency in the face of changing precipitation, especially in underserved communities. EPA's integrated stormwater management research focuses on reducing combined sewer overflows (CSOs), managing stormwater quality and quantity, and using stormwater for augmenting water resources to help communities manage stormwater.
Research Topics
EPA's researchers are studying green and gray infrastructure to help support local, state, and national stormwater management objectives to reduce runoff through infiltration and retention. EPA supports the increased adoption of both constructed and natural green infrastructure in communities through the improvement of models and tools, field and laboratory research, and the evaluation of data from increasing application of green infrastructure practices.
