The hyporheic zone (HZ) has been identified as the river’s liver due to its significant role in processing a variety of water, including nutrients, pathogens, metals, and trace organic contaminants. However, urban streams are often conceptualized as pipes for water conveyance; HZ are not considered or included during construction. Even in channels with HZ present, they have not been engineered and hyporheic exchange may not occur efficiently.

Modular hydraulic conductivity (K) structures placed in the streambed, termed
Biohydrochemical Enhancement structures for Streamwater Treatment (BEST), can enhance water quality. BEST efficiently drive hyporheic exchange using passive pressure gradients. BEST can be designed to generate fluxes and residence times for optimized removal of contaminants in small streams, either with natural sediments or by incorporating reactive geomedia.
