The United States Geological Survey states: "Phosphorus is a common constituent of agricultural fertilizers, manure, [urban runoff], and organic wastes in sewage and industrial effluent. It is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes." Phosphorus is an important contributor to surface water impairments in Minnesota, as illustrated in the map to the right.

Phosphorus in stormwater
This page provides information on phosphorus in urban stormwater, including a discussion of sources of phosphorus and management strategies for minimizing phosphorus loading from urban stormwater runoff to surface water.
Amended media or systems engineered to retain phosphorus
- Soil amendments to enhance phosphorus sorption: This page includes information on phosphorus-sorbing materials, including the following.
- iron filings (Erickson et al., 2012);
- steel wool (Erickson et al., 2007);
- native iron rich soils such as those in the Piedmont of the Mid and Southern Atlantic USA (Hunt et al 2012), or Krasnozem soil in Australia (Lucas and Greenway, 2011);
- Drinking Water Treatment Residuals (WTRs), which are a by-product of drinking water treatment and a source of aluminum and iron hydroxides (O’Neill and Davis, 2012a and 2012b, Hinman and Wulkan, 2012; Lucas and Greenway, 2011; Lucas and Greenway, 2010); and
- sorptive media (Imbrium) (Balch et al 2013)
- Iron enhanced sand filter (Minnesota Filter)
- Layered bioretention systems
