Green Mountain Tunnel
The Green Mountain Tunnel is a mine drainage tunnel in Schuylkill County, Pennsylvania, in the United States. It is one of five major mine drainage tunnels in the watershed of Catawissa Creek. The tunnel discharges into Catawissa Creek near the Audenried Tunnel and the Catawissa Tunnel. The tunnel was constructed in the 1930s and is slightly less than one mile long. Hydrology The average discharge of the Green Mountain Tunnel is 1,440,000 gallons per day (1,000 gallons per minute or 1.75 cubic feet per second). Although a significant majority of the acid mine drainage discharging into Catawissa Creek comes from the Audenried Tunnel, the Green Mountain Tunnel is one of four other mine drainage tunnels that contribute most of the remaining acid mine drainage to the creek. The pH of the waters of the Green Mountain Tunnel ranges from 3.6 to 4.2, with an average of 4.05. The concentration of acidity in the tunnel's waters is 28.05 milligrams per liter and the daily load of acidity is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Conductance
Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter (rho). The SI unit of electrical resistivity is the ohm-meter (Ω⋅m). For example, if a solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is , then the resistivity of the material is . Electrical conductivity or specific conductance is the reciprocal of electrical resistivity. It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter ( sigma), but ( kappa) (especially in electrical engineering) and ( gamma) are sometimes used. The SI unit of electrical conductivity is siemens per metre (S/m). Resistivity and conductivity are inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnels In Pennsylvania
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Tunnels In The United States
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Geotextiles New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging the drain. Geotextiles are synthetic textile fabrics specially m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quakake Tunnel

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. The tunnel is a major contributor of acid mine drainage to the watershed of the Lehigh River. Description The Quakake Tunnel is located in Packer Township near the border between Carbon and Luzerne counties. The tunnel is located to the south of the borough of Beaver Meadows. It is approximately in length. The mouth of the tunnel is at Wetzel Creek and its waters ultimately enter the Delaware River. 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. It drains part of the Spring Mountain coal workings as well as the Beaver Meadow and the Coleraine coal workings. The mouth of th ...

Jeddo Tunnel
The Jeddo Tunnel (also called the Jeddo Mine 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 (eight kilometers) 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. Description The Jeddo Tunnel drains four large coal basins over an area of close to . It also drained the collieries of G.B. Markle & Company. On average the tunnel drains of water each minute. Sometimes the tunnel drains up to 100,000 gallons per minute. The tunnel is about 5 miles (8 kilometers) long and runs between Black Creek and the hills in Butler Valley. It is . The Jeddo Tunnel is located close to the community of Drums. The tunnel drains the nine major minepools in the area via gravity. The Jeddo Tunnel drains the mines in 13 nearby communitie ...

History Sugarloaf massacre During the height of the American Revolution, in the summer of 1780, British sympathizers (known as Tories) began attacking the outposts of American revolutionaries located along the Susquehanna River in the Wyoming Valley. Because of reports of Tory activity in the region, Captain Daniel Klader and a platoon of 41 men from Northampton County were sent to investigate. They traveled north from the Lehigh Valley along a path known as "Warrior's Trail" (which is present-day Pennsylvania Route 93). This route connects the Lehigh River in Jim Thorpe (formerly known as Mauch Chunk) to the Susquehanna River i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potable Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
