COMPLETION DATE:
Construction completed August 1998
Water quality monitoring ongoing: PA DEP, Knox DMO and Slippery Rock University

MATERIALS USED FOR TREATMENT:
900 Tons limestone aggregate (#3)

WATER COLLECTION AND DISTRIBUTION:
Collection: In 6'W x 30'L trench, a 4" perforated SDR 35 PVC pipe was bedded in 1.5' of #3 and #2 river gravel.  Filter fabric was used to prevent siltation.  Native clay was used as a cap to preclude oxygen from the anoxic collection system.

Inlet: From the collection system, the captured flow is distributed by a perforated SDR 35 PVC manifold (30'L) extending along the east end (width) of the drain.

Outlet: The water is collected in the southwest corner in “hand-drilled” perforated SCH 40 PVC pipe (L-shaped; two, 10-foot sections) and outlets through a 4" solid PVC pipe with an air trap into the first settling pond.
