On May 2, Chesapeake Bay Program announced the seven jurisdictions that make up the Chesapeake Bay watershed–Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia–continue to make progress in reducing the amount of nitrogen, phosphorus and sediment pollution that is flowing into the Chesapeake Bay.

The Chesapeake Bay Program uses a suite of modeling tools that show how much pollution is estimated to be reduced by best management practices reported by the watershed jurisdictions each year.

These tools also approximate the pollution reductions that have occurred between 2009—the baseline year for the Bay TMDL—and 2023.

-- Overall nitrogen entering the Bay decreased 17% from 297.8 million pounds in 2009 to 247.6 million pounds in 2023, meeting 57% of the goal to reduce nitrogen by 2025.

-- Overall phosphorus entering the Bay decreased 17% from 17.2 million pounds in 2009 to 14.2 million pounds in 2023, meeting 67% of the goal to reduce phosphorus by 2025.

-- Overall sediment entering the Bay decreased 6% from 18.9 billion pounds in 2009 to 17.8 billion pounds in 2023, meeting 100% of the goal to reduce sediment by 2025.

The model shows that between 2022 and 2023, the agricultural sector was responsible for 43% of nitrogen reductions and 26% of phosphorus reductions. The wastewater sector, during the same period, was responsible for 53% of nitrogen reductions and 67% of phosphorus reductions.

State Progress

The following information demonstrates the progress that each jurisdiction is making toward meeting their goal of having 100% of practices in place by 2025 to reduce nitrogen, phosphorus and sediment pollution--

-- Pennsylvania has achieved 29% of its 2009-2025 reduction goal for nitrogen, 50% of its reduction goal for phosphorus and 58% of its reduction goal for sediment. The Commonwealth did not meet its 2023 pollution reducing targets for nitrogen, phosphorus and sediment.

-- Delaware has achieved 9% of its 2009-2025 reduction goal for nitrogen, 39% of its reduction goal for phosphorus and 64% of its reduction goal for sediment. The state did not meet its 2023 pollution reducing targets for nitrogen, phosphorus and sediment.

-- The District of Columbia has achieved 100% of its 2009-2025 reduction goals for nitrogen, phosphorus and sediment. The District is on track to meet each one of its 2023 pollution reducing goals.

-- Maryland has achieved 83% of its 2009-2025 reduction goals for nitrogen, 100% of its reduction goal for phosphorus and 100% of its reduction goal for sediment. The state did not meet its 2023 pollution reducing targets for nitrogen.

-- New York has achieved 65% of its 2009-2025 reduction goals for nitrogen, 66% of its reduction goal for phosphorus and 26% of its reduction goal for sediment. The state did not meet its 2025 reduction targets for nitrogen, phosphorus and sediment.

-- Virginia has achieved 80% of its 2009-2025 reduction goal for nitrogen, 62% of its reduction goal for phosphorus and 100% of its reduction goal for sediment. The Commonwealth did not meet its 2023 pollution reducing targets for nitrogen and phosphorus.

-- West Virginia has achieved 100% of its 2009-2025 reduction goal for nitrogen, 91% of its reduction goal for phosphorus and 100% of its reduction goal for sediment. The state is on track to meet each one of its 2023 pollution reducing targets.
