The selected sites were both on the East and West branches of the Antietam. The East branch site, Renfrew Park and the West branch Owl’s Club Picnic site were selected for analysis. Red Run 2 was also selected for a statistical analysis.
In addition to using the IBM analytics software, graphs were generated in Microsoft Excel to show pollutant level change as water flows down the East and West branches. Sites all along the East and West branches were selected in order to show any changes.

For the East branch, the selected sites were Antietam Shelter (on the Appalachian Trail), Renfrew Park, and the Baumgardner property on Lyons Road.
For the West branch, the selected sites were Mont Alto State Park, Hess Benedict Road and Owl’s Club Picnic Grounds.
Graphs were also generated for Red Run. There were four sites used to generate these graphs: Red Run Park, Red Run 1 (at Blue Ridge Summit Lions Club Park), Red Run 2 (at the Rt. 16 Appalachian Trail crossing), and the mouth of Red Run (near its confluence with the East branch).

Throughout this process, we were very grateful to property owners, clubs, forest agencies and munici- palities for granting us permission to access these and other stream sites in our monitoring program. These owners and authorities have an interest in our work and have been very cooperative and supportive.
We thank them! continued on page 10
