The federal "pollution diet" imposed on Virginia and other bay states is supposed to reduce the phosphorus, nitrogen and sediment dumped into the Chesapeake Bay and its feeder rivers. Computer models based on a suite of reduction practices estimate that diet is mostly working. But real-world monitoring data shows a different story, according to the Environmental Integrity Project, a nonprofit anti-pollution group based in Washington. Measurements of pollution loads that actually make their way into the estuary indicate nitrogen appears to be declining at a slower rate than models predict, and phosphorus and sediment actually appear to be increasing, the group says.
