Thatâs especially true on Pennsylvania farmland, including in Lancaster County. All of that is according to a report released Tuesday by the Chesapeake Bay Foundation, which noted some improvement in pollution levels but gave the bay a low grade of D-plus â the same grade it got in a previous report issued two years ago. But Don Ranck, the Lancaster County Farm Bureauâs president, said pollution reduction goals for the bay are unrealistic. âYes, farmers want to help. Farmers want to do what's right,â Ranck said. âBut we have a goal that is impossible to reach. They set the goal higher than can possibly be reached.â
