The Quakake Tunnel (also known as the Meadow Tunnel [1] or the Beaver Meadow Tunnel [2] ) is a mine drainage tunnel in Carbon County, Pennsylvania, in the United States. [3] [4] The tunnel is several thousand feet long and has a discharge of thousands of gallons per minute. It was the subject of an Operation Scarlift report. [5] The tunnel is a major contributor of acid mine drainage to the watershed of the Lehigh River.
The Quakake Tunnel is located in Packer Township near the border between Carbon and Luzerne counties. [3] [5] The tunnel is located to the south of the borough of Beaver Meadows. It is approximately 3,900 feet (1,200 m) in length. [4] The mouth of the tunnel is at Wetzel Creek and its waters ultimately enter the Delaware River. [3] [5] The tunnel's direction is mainly north and 60 degrees west and the other end of the tunnel is in coal mine workings belonging to the Lykens Vein. [3] [4] It drains part of the Spring Mountain coal workings as well as the Beaver Meadow and the Coleraine coal workings. [4]
The mouth of the Quakake Tunnel is slightly over 1,300 feet (400 m) above sea level. The upper end of the tunnel is not significantly higher. [5]
The Quakake Tunnel is one of four sources of acid mine drainage in Carbon County and one of eight in the watershed of the Lehigh River. [6] [7]
The portal of the Quakake Tunnel is in severely fractured red shale. Timbering is required to support the tunnel at this location. Other varieties of rocks are found deeper into the tunnel. Sandstone belonging to the Pottsville Formation is found from 1,450 feet (440 m) above the mouth of the tunnel to 1,800 feet (550 m) above the mouth of the tunnel. From this area up to 2,000 feet (610 m) from the tunnel's mouth, the tunnel is mostly in conglomerate rock. There are few fractures in the rock in this part of the tunnel. From 2,100 to 2,200 feet (640 to 670 m), 3,300 to 3,400 feet (1,000 to 1,000 m), and 3,650 to 3,850 feet (1,110 to 1,170 m), there are more conglomerates. Other rock types found deeper than 2,000 feet (610 m) include red shale, gray shale, and sandstone. [4]
There are coal seams at the upper end of the Quakake Tunnel. [5]
The Quakake Tunnel is collapsed in places. [3] Historically, there was also debris in the tunnel. A number of minor thrust faults are also found within the tunnel. A synclinal axis occurs at 1,900 feet (580 m) from the mouth and an anticlinal axis occurs at 2,800 feet (850 m) from the mouth. [4] The tunnel is at the southeastern edge of the Jeansville Coal Basin. [5]
The water of the Quakake Tunnel comes from surface water that flows through broken strata and abandoned strip pits. [5]
The discharge of the Quakake Tunnel is greater than the acid mine drainage discharges that feed Hazle Creek at Stockton. The load of acidity in the tunnel is also greater than the aforementioned acid mine drainage discharges. [3] The tunnel causes Wetzel Creek to be acidic as far downstream as its mouth. [4] Between 1979 and 1980, the pH of the discharge of the Quakake Tunnel ranged from 3.4 to 4.6, with an average of 3.9. The total concentration of acidity ranged from 66 to 110 milligrams per liter, with an average of 80 milligrams per liter. [5]
Between 1979 and 1980, the concentration of aluminum in the waters of the Quakake Tunnel ranged between 5.5 and 17.0 milligrams per liter and averaged 9.8 milligrams per liter. The calcium concentration ranged from 6.0 to 39.8 milligrams per liter, with an average of 14.1 milligrams per liter. The iron concentration ranged from 0.18 to 0.97 milligrams per liter, with an average of 0.83 milligrams per liter. The concentration of sulfates ranged from 80 to 200 milligrams per liter, with an average of 144 milligrams per liter. [5]
Between 1973 and 1974, the discharge of the Quakake Tunnel ranged from 10.1 to 33.6 cubic feet per second, with an average of 21.3 cubic feet per second. The water temperature ranged from 9 to 10 °C (48 to 50 °F), with an average of 9 °C (48 °F). Between 1979 and 1980, the average water temperature of the tunnel's discharge was 9 °C (48 °F). [5] As of 2008, the discharge of the tunnel is over 6000 gallons per minute (13.37 cubic feet per second), making it the largest abandoned mine discharge in the watershed of the Lehigh River. [8]
The Quakake Tunnel was constructed for the purpose of draining water from deep mines via gravity. [5]
A prototype installation of a treatment system for the Quakake Tunnel was constructed in 1978 and 1979. [9]
The Quakake Tunnel was cleared of debris by the Pennsylvania Department of Environmental Protection at some point in the past. After this, it was possible to access the tunnel between its lower end and its upper end for the purposes of mapping it. A study once suggested that it was possible to place a seal in the tunnel between 1,800 feet (550 m) and 2,000 feet (610 m) from its mouth. [4]
The treatment of the Quakake Tunnel ranks third in priority among eight acid mine drainage discharges in the watershed of the Lehigh River. [10]
The Lackawanna River is a 42-mile-long (68 km) tributary of the Susquehanna River in Northeastern Pennsylvania. It flows through a region of the northern Pocono Mountains that was once a center of anthracite coal mining in the United States. It starts in north Wayne County, Pennsylvania and ends in east Luzerne County, Pennsylvania in Duryea, Pennsylvania. The lower reaches of the river flow through the urban areas of Scranton, which grew around its banks in the 19th century as an industrial center. Its name comes from a Lenape word meaning "stream that forks".
Mahanoy Creek is a 51.6-mile-long (83.0 km) tributary of the Susquehanna River in Northumberland and Schuylkill counties, Pennsylvania. There are at least 35 sources of acid mine drainage in the creek's watershed. Anthracite was mined in the upper part of the Mahanoy Creek watershed in the 19th and 20th centuries. Mahanoy Creek's tributaries include Schwaben Creek, Zerbe Run, Little Mahanoy Creek, Shenandoah Creek, and North Mahanoy Creek. Little Mahanoy Creek and Schwaben Creek are two streams in the watershed that are unaffected by acid mine drainage. Schwaben Creek has a higher number and diversity of fish species than the main stem.
The Jeddo Tunnel is a drainage tunnel at water level in Pennsylvania. It is one of the Coal Region's biggest discharges of mine water. The tunnel is five miles long and was constructed between 1891 and 1894, and at the time of its construction, was reputed to be the largest mine drainage tunnel in the world. It consists of major tunnels A and B, and minor tunnels C, D and X.

The tunnel discharges into Catawissa Creek further upstream than any other mine drainage tunnel in the watershed. The tunnel was constructed in the 1930s and a passive treatment system may or may not be installed at the site of the tunnel. The tunnel is several hundred feet long.
The Catawissa Tunnel is a mine drainage tunnel in Schuylkill County, Pennsylvania, in the United States. Its properties include the discharge, the pH, the chemical hydrology, and the water temperature. A total of 30 different metals and metalloids have been observed in the tunnel's waters. The hydrological data comes from a gauge on the tunnel at a location of 40°54'39" north and 76°03'59" west and an elevation of 1,440 feet (440 m) above sea level. Some of the most abundant metals in the waters of the tunnel include iron, aluminum, and manganese. These metals have concentrations on the order of several milligrams per liter. A number of other metals have concentrations on the order of micrograms per liter and some metals are found in even lower concentrations. Nonmetals such as nitrates, sulfates, fluorides, chlorides, and silica are also present in the tunnel. The concentrations of such nonmetals range between several micrograms per liter and several milligrams per liter.
Cranberry Creek is a tributary of Stony Creek in Luzerne County, Pennsylvania, in the United States. It is approximately 4.4 miles (7.1 km) long and flows through Hazle Township. The creek is affected by acid mine drainage. It also contains metals such as iron, manganese, and aluminum. It is in the drainage basin of the Jeddo Tunnel. Major roads in the creek's watershed include Pennsylvania Route 924, Pennsylvania Route 309, and Interstate 81. At least one bridge has been built over it.
