Runoff has sent more nitrogen, sediment into Bay than anticipated
New data has given the Chesapeake Bay Program a more accurate picture of pollution in the watershed.

Could poorly maintained Storm Water Management systems be part of the problem for Nitrogen spikes in the Watershed ?
It appears the UNC Chapel Hill is researching 'Nitrogen Fixation'. Nitrogen Fixation occurs when systems designed to remove sediments become Nitrogen Generators. source : http://science.unctv.org/content/video/retention-pond
Gary: Can you provide a link to the monitoring data you are referring to? Thank you. Bill
Pollution controls put in place over the last twenty-five years have lowered the amount of nutrients and sediment entering the nation’s largest estuary. Long-term water quality monitoring data has shown a trend of decreasing sediment and nutrient loading over the last ten-years from the Susquehanna River watershed. While CBP's modeling efforts are sophisticated and constantly being updated, the outputs do not agree with the water quality monitoring data. More resources should be dedicated to local watershed monitoring to truly calibrate the model to reflect the real world.
Thank you!
