E&S Environmental Chemistry was contracted to write national protocols for the U.S. Forest Service for the sampling and analysis of lakes and streams throughout the United States that receive atmospheric inputs of nitrogen, sulfur, pesticides, and other toxic materials.

Shenandoah National Park, located in the Blue Ridge Mountains in Virginia, contains exceptional natural features and awe-inspiring views from Skyline Drive and the Appalachian Trail.

E&S Environmental Chemistry wrote and designed this pamphlet for the National Park Service to help interested stakeholders understand the effects of air pollution on the natural and scenic resources of Shenandoah National Park.
