Example of nearby areas of snow accumulation from distribution/plowing. Pollutant concentrations in stockpiled snow are a function of the source area for the snow and the length of time the snow was in the source area.

Minnesota stormwater managers must recognize that runoff from snowmelt has special characteristics, and that BMP design criteria addressing only rainfall runoff might not work well during cold periods. This becomes a major problem because a substantial percentage of annual runoff volume and pollutant loading can come from snowmelt.
