More pollution flowing into Chesapeake Bay than expected

Lisa Graybeal is a third generation dairy farmer in Lancaster County.
After decades of work and billions of dollars spent, a massive effort is still underway to clean up the Chesapeake Bay. In 2010, Pennsylvania and other states in the watershed began a new plan to restore the health of the bayâwith the goal to fully implement pollution reduction practices by the year 2025.
But new data shows more nitrogen and sediment is running off into the bay than previously expected.
âWhat happens in Pennsylvaniaâ
As Lisa Graybeal walks around her family dairy farm, she thinks about how times have changed.
âIn 1942, they milked 60 jerseys in a bank barn,â she says.
That was back in her grandfatherâs day. Now there are 720 cows, milked with machines.
âMy dad remembers when they still had a horse to do things, but it was soon after they moved here that they got the first tractor.â
Her 1,200 acre farm in Fulton Township is in the southern most portion of Lancaster County, along the Pennsylvania-Maryland border. Itâs one of many in the Chesapeake Bay watershed.
No other state contributes more pollution to the bay than Pennsylvania, and its farms are the largest source of nutrient and sediment pollution. Graybeal says she feels like farmers get a bad rap. Theyâve been stewards of the land, and sheâs always tried to use best management practices.
âWeâve gone on with cover cropping, which was done here in the 70âs and early 80âs,â she says. âWe do not plough anymore. We do all no-till cropping.â
Despite efforts from people like Graybeal, what happens in Pennsylvania does not always stay in Pennsylvania.
Katherine Antos tracks bay water quality for the federal Environmental Protection Agency, which is part of the Chesapeake Bay Programâ a regional partnership that includes the District of Columbia, Pennsylvania, Delaware, Maryland, New York, Virginia, and West Virginia. All have agreed to implement pollution reduction practices to meet 60 percent of the goal by 2017.
âWhat happens in Pennsylvania has a very large impact on the Chesapeake Bay,â says Antos.
Farming certainly isnât the sole source of pollution. Antos says two pollution sources that have seen major reductions in recent decades are the wastewater sector and atmospheric depositionâair pollution contaminating waterways. But new Chesapeake Bay Program data shows more work needs to be done on runoff from urban areas, septic systems from suburban development, and farming.
âNitrogen and sediment reductions are not on track with the partnershipâs long-term water quality goals,â says Antos. âThereâs more entering the bay than we previously thought.â
Even though those levels are not on track, phosphorus pollution reductions are ahead of schedule.
âWeâre still moving in the right direction,â she says.
Costs vs. benefits
But the question inevitably arisesâwho bears the costs, and who gets the benefits? If farmers like Lisa Graybeal have to spend more money to curb pollution, or cut land out of production, that may be good for fishermen in Maryland, but it could hurt farmersâ bottom lines upstream.
âWe believe EPA has clearly exceeded its authority under the Clean Water Act.â says Mark OâNeil, a spokesman for the Pennsylvania Farm Bureau.

The group is part of a lawsuit challenging the EPAâs authority over the bay cleanup efforts. The case is currently pending in a federal appeals court.
âWe want to make sure our farm families are not put in a situation that threatens the economic viability of the farm family,â he says. âEspecially in the future.â
But if you look at the bay itself, and all the economic services it providesâlike food, water, aesthetics, and recreationâthe benefits of cleaning it up may be well worth it. Thatâs the conclusion of a new economic report from the Chesapeake Bay Foundation.
Economist Spencer Phillips wrote the report and says if all the pollution plans are in place by the 2025 target, the economic benefits could be more than $22 billion per year.
âIt looks like the benefits are going to far outweigh the costs, by a ratio of something like four to one, by our estimates.â
Back on her Lancaster County farm, Lisa Graybeal stands on a hillside and admires the rolling landscape. As the crow files, weâre just a few miles from the Susquehanna Riverâwhich supplies half the freshwater for the Bay.
âFor years and generations weâve done these practices,â she says. âWe want to see clean streams, creeks and riversâ as anyone else does.â
She says itâs a goal sheâll keep working towards.
