Pennsylvania state cabinet officials say they’ve made great strides in their efforts to clean up the Chesapeake Bay. But environmental groups say the state is not doing enough to meet deadlines set for 2025 to reduce its pollution to the bay. In the annual Chesapeake progress report released last week, state officials say that new funds and cooperation with several dozen counties are helping the state keep its promises. The overall health rating of the bay reportedly improved by six percent, but advocates say they’re still concerned with what they say is Pennsylvania’s excess nutrient pollution caused by chemicals, oil and agricultural waste.
