Impact/Purpose:
Provides an overview of the ongoing research at Fort Riley, KS
Description:
Many communities are implementing green infrastructure stormwater control measures (SCMs) in urban environments across the U.S. to mimic pre-urban, natural hydrology more closely. Permeable pavement is one SCM infrastructure that has been commonly selected for both new and retrofit applications. However, there is limited information about the infiltration and exfiltration mechanisms from these systems that control performance. A permeable pavement site located at the Seitz Elementary School on Fort Riley, Kansas was selected for this study. An 80-space parking lot was built behind the school as part of an EPA ORD collaboration with the U.S. Army under the Net Zero program. The parking lot design includes a permeable interlocking concrete pavement (PICP) section along the downgrading edge. This study is monitoring the stormwater captured by PICP’s gallery, aquifer recharge rate, and changes in the quality of the stormwater associated with PICP and movement in vadose zone. To this end, monitoring sensors are embedded within the storage gallery beneath parking lot. A small network of wells, piezometers as well as tensiometer with pore water samplers have been established near the parking lot to monitor movement in the subsurface and collect samples for analysis.
