Activities in 'Pennsylvania'

Toby Creek, Elk County
description: A 30-day continuous field trial of the pulsed limestone bed treatment process developed by the USGS was conducted in cooperation with PADEP at Toby Creek from May through June, 1999. Results showed effective neutralization of acidity with no evidence of limestone coating or armoring.

Swatara Creek
description: Anthracite deposits in the northern basin have dramatically affected the water quality miles downstream. Evaluation of limestone treatment of AMD and characterization of water quality conditions are currently being studied to evaluate hydrologic and geochemical factors of coal-mine discharges.

Friendship Hill Historic Site, Fayette County
description: A 14-month continuous field trial of the pulsed limestone bed treatment process developed by the USGS was conducted at this site in cooperation with the National Park Service from June 2000 through August 2001. Despite high influent acidity and iron loading here, effluent pH averaged 6.8 with about 50 to 300 mg/L alkalinity, depending on CO2 addition.
