INRC Spring 2022 Seminar Series: Removing Dissolved Phosphorus from Flowing Water with P Removal Structures: the Good, the Bad and the Ugly

Wednesday, April 27, 2022 - 3:10pm

INRC Spring 2022 Water Quality Research Seminar Series: Focus on Phosphorus
Presenter: Chad Penn is a soil chemist with the USDA-Agricultural Research Service and Purdue University..

Dissolved phosphorus (P) loss from high P soils is a long-term problem that conventional BMPs are unable to address. Phosphorus removal structures are landscape-scale filters designed to remove dissolved P from flowing water at “hot spots” until soil P levels have been reduced. This presentation will describe how P removal structures work, provide an overview of several styles of structures with performance and economics, and introduce the nature of the design process and design software, P-Trap.  

The seminar series will be presented online via Zoom. Sessions are free and open to the public, but participants are asked to register in advance at: will be recorded and posted on INRC’s website with speakers’ permission.
