Upgrades to sewage treatment plants have helped improve water quality in the Chesapeake. And, each Bay state has developed a clean water blueprint outlining the steps that must be taken to reduce pollution much further, so that we can fully restore water quality in local rivers, streams, and the Bay.

And Pennsylvania and EPA must effectively carry out their roles to make sure it does.
