A project is underway to reduce pollution in Epiphany Creek. A filter will be installed that uses sand, iron filings and biochar filter media to bind and remove phosphorus and E. coli bacteria from urban stormwater runoff. The iron removes phosphorus which is the nutrient that supports rapid algae growth. The biochar removes E. coli which is bacteria found in animal waste.
Epiphany Creek flows through Robinson Park in Coon Rapids. The filter will be constructed within the floodplain adjacent the creek. A structure will be constructed within Epiphany Creek to divert polluted water over and through the filter. Cleaner water then leaves the filter via drain tile and continues its path to join with Coon Creek.
The project, which will take four to eight weeks to complete, is supported by a Minnesota Clean Water Fund grant. The Coon Creek Watershed District awarded the contract for the project to North PIne Aggregate, Inc.
