Phosphorus Reduction Enhancements
Public Water 19022500
|In 2013, the City of Apple Valley received a grant for improvements to pond EVR-P12 (Public Water 19022500) from the Board of Water and Soil Resources through its Clean Water Fund program. EVR-P12 is a major contributor of phosphorus to Long Lake which has been on the impaired waters list since 2002. The Long and Farquar Lakes TMDL calls for a reduction in phosphorus levels from EVR-P12 to meet water quality goals.
Improvements to EVR-P12 will include installation of an iron enhanced sand filter (Minnesota Filter)
and aluminum sulfate treatments (alum)
. The projects are predicted to reduce phosphorus contributions to Long Lake by 61 pounds per year, or about 24% of the watershed phosphorus reduction recommended. The project will take place over a three year period, beginning spring 2013 through December 2015.
