Two universities have joined forces to study how well stormwater best management practices (BMPs) address pollution, water quality, and sustainability.

The Temple-Villanova Sustainable Stormwater Initiative is under way at Pennsylvania's Pennypack Creek Watershed, which covers 56 square miles over 12 municipalities (including Philadelphia), and serves more than 300,000 residents. The area is challenged by unplanned land development, poor stormwater management, impaired water quality, and obsolete flood-plain maps.

The study will look at a range of BMPs, including wetlands, ponds, and riparian buffers. It also involves installation of subsurface infiltration. The system will be able to store and infiltrate more than 10,000 gallons of runoff.
