So your stormwater runoff is polluted with bacteria…now what? In urban areas bacteria sources are diffuse –pet and wildlife waste, sanitary overflows and leakages – and options for reducing loads are limited. This presentation will discuss the use of biochar, iron and sand filters to remove bacteria and phosphorus from urban runoff in a watershed in the Minneapolis metropolitan area. Catch basin inserts, pond filter benches and a filter box were installed and stormwater inflow and outflow were monitored for one to two years. Preliminary results and future monitoring plans will be discussed.

Where:   4275 Boelter Hall Room

When:     11:00 AM – 12:00 PM, Thursday, February 15, 2018
