Media Filtration for Urban Stormwater Runoff Treatment

Whether underground such as the Delaware Sand Filter or above-ground such as with bioretention, the media used in stormwater treatment systems impacts performance. Multiple research projects have investigated the impact of the interaction of media and pollutant characteristics on treatment effectiveness.

This work started with my dissertation decades ago. 1999 Clark and Pitt Media filter EPA report

Since then, guidance has been published on media selection based on this and additional research.

Water Research article on designing media to treat desired pollutants.

Specific aspects of media performance also have been investigated.
