A brief graphic from the Chesapeake Bay Foundation that depicts the EPA’s Chesapeake Bay Program Watershed Model. The columns are separated by pollution source — agriculture, urban runoff, wastewater, septic, and all the above. The rows are separated by state, and then within state by nitrogen, phosphorus, and sediment pollution. The large majority of goals have been met by states. By source, wastewater has been regulated the best as it has the highest success rate in terms of meeting its 2017 pollution reduction goal. By pollutant, nitrogen tends to be the most consistently troubling across all the states and sources. West Virginia wins in terms of being on track. Fortunately, the holistic goals of total source pollution reduction are, for the most part, being met.
