Bentonville, Arkansas, is located in the Ozark Mountains region, characterized by karst topography with porous limestone bedrock. Stormwater runoff from urban and industrial areas can rapidly infiltrate groundwater or flow into sensitive streams. The Illinois River watershed, which receives drainage from this area, is a focus of regional water quality efforts due to nutrient pollution and sedimentation. Effective stormwater management at facilities like this distribution center is critical to protect aquatic habitats and drinking water sources.
