Looking for more good recipes for the Chesapeake Bay Pollution Diet? Look no further than CSN’s new Fact Sheet: Elimination of Individual Nutrient Discharges from Gray Infrastructure!
There is conclusive evidence that high nutrient discharges increase Nitrogen and Phosphorus levels in dry weather urban stream flow. These discharges can collectively account for as much as 20 to 40% of the annual nutrient load in urban watersheds, depending on the age and condition of its gray infrastructure.
