The Montour Run Watershed Association's (MRWA) has been involved in efforts to construct a passive water pollution treatment system on what is known as MKR3 discharge, the single largest source of aluminum pollution in Montour Run. The Milk Run passive system is designed to annually remove 72,000 pounds of acid and 7,000 pounds of aluminum from the MKR3 abandoned mine drainage (AMD).
Other entities providing vital support to the MRWA Milk Run effort include Continental Communities, LLC; the Allegheny County Conservation District (ACCD); the not-for-profit Stream Restoration Incorporated (SRI); Independence Conservancy; Great Rentals, LLC; the Washington County Conservation District; and PA Department of Environmental Protection.
All necessary permits for construction of the passive treatment system have been obtained by MRWAs contractor, BioMost, Inc. (http://www.biomost.com/ Opens a New Window. ). After delaying the start of work due to the excessively wet spring, clearing of vegetation at the site began in early July. A photograph showing tree removal progress is below.
