[3] The Jeddo Tunnel drains four large coal basins over an area of close to 33 square miles (85 km2).

[7] The tunnel is about 5 miles (8 kilometers) long and runs between Black Creek and the hills in Butler Valley.

These communities are Hollywood, Lattimer, Minesville, Drifton, Harleigh, Sandy Run, Ebervale, Humboldt, Cranberry, Harwood, Stockton, and the Eckley Miners' Village.

Besides minepools, contributors to the flow of the tunnel include precipitation draining through mines, seepage of streams, and water falling through sinkholes and cave-ins.

[3] At the end of the 1990s, the sulfate, iron, manganese, and aluminum levels in the Jeddo Tunnel were significantly lower than in previous years.

The tunnel water's pH level is the lowest at the end of summer and the beginning of autumn.

[3] The basic geology of the Jeddo Tunnel's watershed was created 345 million years ago, during the Carboniferous Period.

Two teams of workers used compressed air drills and explosives to build the tunnel from both ends.

[11] The Jeddo Tunnel's original purpose was to remove the water from deep coal mines in the eastern middle anthracite field.

When constructed, the tunnel was considered to be an engineering marvel; however, in modern times, Alan C. Gregory describes it as "a dinosaur that survived extinction".

[9] The water quality of the Jeddo Tunnel has improved slightly since the deep-mining industry stopped.

Between 1949 and 1950, group led by a person named Ash gathered data on the tunnel's water quality and discharge.

The Hazleton City Authority conducted a study at the beginning of the 1970s, attempting to determine if the tunnel's outflow was of suitable quality for drinking water.

The United States Geological Survey monitored the tunnel's water quality and flow in 1975 and again in 1991.

The Wildlife Conservancy, Bloomsburg University, and the Susquehanna River Basin Commission all studied the Jeddo Tunnel between 1995 and 1998.

[3] The National Renewable Energy Laboratory once conducted a study to determine whether it would be worthwhile to install a hydroelectric system in the Jeddo Tunnel.

Several studies have attempted to fix the pollution coming from the tunnel but their proposed plans cost at least $15,000,000 and take at least 20 years.

Jeddo Tunnel A goes from Ebervale Mammoth Vain slope number 2 to Little Nescopeck Creek and is 15,100 feet (4,600 m) long.

[3] The water that the Jeddo Tunnel drains is polluted due to past mining in its vicinity.

Creating perimeter drains to pick up runoff from nearby ridges is another proposed method of reducing the tunnel's discharge.
