Abandoned Mine Drainage and
Water Supply
Andy McAllister
Regional Coordinator

What is AMD?
• Abandoned vs. “Acid”
• Pre- 1977
• Bituminous region and Anthracite region

Extent of the problem
• PA has the most abandoned mine problems of any
state.
• Affects surface waters from abandoned discharges.
• Mine pools below the surface. Some may be
reasonable quality.
• Contamination from runoff from surface
disturbances as well

Main constituents of concern in AMD
affecting water supplies in Eastern
Coalfields
• Fe
• Al
• Mn
• Acidity
• Sulfates

Treatment options for surface
discharges
• Hard to pigeonhole treatment technology.
Every discharge different.
• Passive vs Active treatment
– Cost
– Ownership of systems
– Available land
– Operations/Maintenance

Can we treat the discharges that enter
surface waters?
• Fe, relatively easy,
– aeration, settling
• Mn, more difficult, high pH required
• Al, relatively easy, increase pH
• Acidity, relatively easy, using limestone, chitin
• Sulfate
– Bioreactors, don’t remove all.
– RO, can be done but very
expensive.

Water wells and Mine pools
• Some water wells in coalfields are tapping into
abandoned mine pools.
• Some Mine pools may be relatively good
quality.
• Changes in pool level can initiate problems—
can expose a new reactive area in mine.

Surface Mining Control and
Reclamation Act of 1977
• Provides for states to use part of their annual
grant toward providing water supplies to areas
affected by past mining activities.

Scott Alexander with Malcolm Crittenden and Robert Ryder, PA Department of Environmental Protection (DEP), “Instream Limestone Sand Dosing in the Allegheny Plateau” Attendees will learn of the successful recovery of trout populations in low-buffered, acidic streams by the use of alkaline treatments. Documented low-cost/long term trout restoration methods such as (ILS) may be useful for other watersheds dealing with stream acidification because several high cost alternatives have been proposed in Pennsylvania which on analysis may deliver far less stream-alkalinity per dollar.

Jill Burrows Ph.D. Candidate, Lehigh University, “Geochemical and Hydrologic Controls on Abandoned Coal Mine Discharge” Water samples were collected from 23 Coal Mine Discharges (CMDs) in the summer and fall of 2012 in the anthracite coal region of Pennsylvania to evaluate the changes in geochemistry and hydrology over time by comparing the results to studies conducted on the same discharges in 1975, 1991, and 1999 by the U.S. Geological Survey. Geochemical modeling was used to establish a timeline for inorganic pyrite dissolution.

The Lower Lackawanna Watershed near Scranton, PA, is polluted by the largest abandoned mine drain (AMD) in the eastern US. The Old Forge Borehole spews 100 cubic feet per second of iron laden water into the Lackawanna River decimating the aquatic habitat and fish populations for miles downstream and into the Susquehanna River. This assessment was completed in 2012 and the plan recommends cleaning up this discharged and a related discharge, the Duryea Breach, in order to remove approximately 5 tons of iron per day using an active treatment plant. The plant could also have many other beneficial effects besides producing clean water, like hydroelectric power, geothermal heating, iron oxide resource recovery. With these added benefits, the initial ~$15 million investment in a plant could be paid off over and over again.

Eric Null, Conemaugh Valley Conservancy (CVC), “Benthic Macroinvertebrate as Indicators of Mine Drainage Impacts and Recovery Efforts” Benthic macroinvertebrates have been used as water quality indicators for decades, but significant weight on the information that they provide has only occurred in recent years. Their communities provide a historic look at water quality due to their inability to seek refuge during times of pollution episodes. Correlating acid impacts with these “stream bugs” requires a much deeper look into the communities than some standard metrics allow.

Tim Danehy and Bruce Leavitt, Consulting Hydro-geologist, BioMost, “Passive Aeration Using a Trompe“ Water aeration is needed at many mine drainage treatment facilities to oxidize ferrous iron or to remove dissolved carbon dioxide. Typical aeration accomplished through surface diffusion, cascade aeration, mechanical aeration, or with chemical reagents such as hydrogen peroxide. Using an ancient device known as a Trompe, it is possible to achieve the benefits of mechanical aeration without the need for electricity, motors, or any moving parts.

Sandra McSurdy, U.S. Department of Energy (DOE), ”Treating Flowback Water with Acid Mine Drainage (AMD) for Reuse in Shale Gas Activities” Researchers at the University of Pittsburgh and the U. S. DOE are developing a treatment for flowback water utilizing AMD. Treating and reusing flowback water on-site will reduce the amount of freshwater needed and the amount of wastewater that needs to be hauled by truck. Sulfate removal tests were performed on flowback and AMD water mixtures with a goal to achieve a final sulfate concentration of less than 100 mg/L for reuse.

Incorporating the design features that were successful in the treatment capacity of the 1.2 acre wetland at the Flight 93 site for a typical flow = 775 gpm. The average percent removal was roughly 70% for iron and 50% for manganese within the wetland. This analysis allowed for a design foundation of the polishing aerobic wetland at the Clyde Mine Water Water Treatment Facility and the potential application at other mine water treatment locations where a relatively minor amount of polishing is needed to enhance iron and manganese removal for the final discharge.

Metal Reclamations Units (MRUs) are passive, modular, scalable, rapidly deployed wetland bioreactors. The biofilm which grows upon the support matrix inside the MRUs is self-selecting and determined by the introduced pollutants and how they are attenuated throughout the treatment process. Currently, our systems function as tertiary treatment at six sites removing Mn and Al, pH<7,><5.5> minimum, demonstrated rates up to 4kg/day of Fe captured using two MRUs Mk1.5s in series, residence 20-25 minutes, flow 280Lpm (5).

The Department of the Interior’s Office of Surface Coal Mining Reclamation and Enforcement presented Northampton Fuel Supply Company, Inc. (NFS) with the “Excellence in Surface Coal Mining and Reclamation” National Award in September 2016 for the land reclamation at the Loomis Bank Operation off of Middle Road in Luzerne County, Hanover Township, PA. The Loomis site was an abandoned culm bank that covered over 100 acres of land. NFS started operations at the site in the late nineties and processed over a million tons of the culm material converting it to a viable fuel for power generation at Northampton Generating Company, LP’s (NGC) power plant located in Northampton, PA.

The Lausanne Tunnel in Jim Thorpe was installed in 1906 to dewater the coal fields in this area. The tunnel discharges about 6000 gal/min of drainage that is relatively high in iron and manganese but fortunately, the pH is relatively high and aluminum content is low. The remediation installed in 2004 was a two part passive wetland system that has been the focus of the conservation efforts by a number of conservation organizations since that time. My involvement has been to engage the local Sierra Club as well, the local trout stocking clubs and other organizations to provide funding and manpower for upgrades at the site. In 2007, two 5ft rectangular weir flow monitors were installed, one in the wetland and the other in the bypass flow, which consists of 2/3rd of the tunnel discharge flow. Pressure transducers and solar powered data loggers were installed to record both flows so that further hydrological engineering could be applied to optimize the wetland treatment while also devising a treatment plan for the bypass flow. In 2011, artesian aerators were added to the feeder pipes to improve aeration of the water entering the wetland. The aerators, however, did consume some of the available head pressure and reduced wetland feed flow so in 2014 a 3rd 14” feeder pipe was excavated and installed bringing the wetland flow rate back to the 1800 gal/min design rate. In 2016, a solar powered compressor was installed with two aerator heads added to the wetland to further boost dissolved oxygen. Iron test kits and dissolved oxygen monitors have been used to evaluate the iron removal effectiveness of the wetland and the extent of oxygen saturation. The next steps at for further improvement are the installation of cascading settling basins in the bypass flow as well as optimization of the wetland flow distribution. This presentation will feature presentation of technical flow and composition data as well as drone video of the site.
