A look at how expanded natural gas drilling in Pennsylvania’s forests could impact the Chesapeake Bay, from the Chesapeake Bay Journal:

…The analysis also raises a concern for Chesapeake cleanup efforts. The conservancy estimates that about 46 percent of the drilling would take place within the Bay watershed. That suggests the forest loss within the watershed portion of Pennsylvania could be between 45,000-110,000 acres.
For comparison, that’s enough land to build between 1 to 2.5 District of Columbias.
Because forests absorb more nutrients and retain more sediment than other land uses, their loss could result in more of those pollutants reaching local streams.
Assuming those forests are converted to meadow, and applying loading rates derived from the Bay Program model, rough estimates suggest it could increase the amount of nitrogen runoff reaching local streams between 30,000-80,000 pounds a year; while phosphorus could increase between 15,000-40,000 pounds; and sediment could increase between 18 million to 45 million pounds. The variation depends on whether the amount of forest lost was at the low, or high end of the conservancy’s estimates.
