This stormwater manual contains information on pollutant removal for a limited number of pollutants. Links to this information are provided below. Users should be aware that the there is considerable information on pollutant removal in the literature. The information in this manual is therefore subject to change and often reflects ranges found in the literature rather than specific values. Pollutant removal is a function of many factors, including design, construction, and maintenance of the BMP, quality of incoming stormwater, time of year, and so on. We have included additional links to information on pollutant removal. Finally, the reader should be aware that each BMP discussed in this Manual has an article (webpage) on stormwater credits, and additional information on pollutant removal may be found in those credit sections.

Links to tables in the Minnesota Stormwater Manual.

• BMP pollutant removal for phosphorus
• Pollutant concentrations and removals for iron enhanced filters
• Pollutant removal percentages for bioretention BMPs
• Pollutant removal percentages for filtration BMPs
• Pollutant removal percentages for stormwater pond BMPs
• Annual TSS removal from ponds and filters
• Examples of the estimated pollutant load reductions for a stormwater reuse storage system sized for the average storm event runoff volume
• Summary of pollutant removal efficiencies in wet stormwater ponds/stormwater wetlands
• Total P and particulate P removal from BMPs without iron in the filter media
