Klemow, Kenneth M.* and Thomas Chesnick. 2001. ASSESSMENT OF THE EARTH CONSERVANCY'S PHASE II MINE DRAINAGE TREATMENT SYSTEM. Contributed paper: Pennsylvania Academy of Science meeting. Abstract: Journal of the Pennsylvania Academy of Science 74:xxx.

In May 1999, a 2.2 acre constructed wetland complex to treat mine drainage discharging from the Askam Borehole in central Luzerne County began operation. The treatment complex consists of an aeration device, oxidation pool, and two polishing wetlands, and receives 350 gallons per minute of minewater. Water samples were taken throughout the wetland between September 1999 and August 2000 to assess its performance. During that time, iron loading into the wetland varied from 270 to 395 lbs Fe/day. Iron discharge levels from the wetland were generally under 25 lbs Fe/day. Iron removal efficiency exceeded 95% for most months that samples were taken, thus indicating that the wetland is performing as hoped. The results show that properly designed wetlands can effectively help clean AMD-impacted waters of the anthracite region.
