Bingham Canyon Mine
Bingham Canyon or commonly known as Kennecott Copper Mine is the world`s deepest man-made open pit mine for copper and gold, located near Salt Lake City, Utah. The mine is owned by Rio Tinto Group. According to “Top 10 Deep Open-pit Mines” article, since Bingham Canyon Mine started its operation in 1906, it has become the “granddaddy” of all copper mines with a diameter of 2.75 miles (4,5km) and a depth of 0.75 mile (1,2km). In fact, Bingham Canyon Mine is also called "the richest hole on Earth” for the average $1.8 billion dollars value production of metals produced annually (Arrlington & Hansen, 1963). However, despite being the largest copper mine the USA, it also produces a wide range of byproduct metals and waste rocks; approximately, “three billion metric tons” of waste

Aside from acid coming from the leaching of pyrite, lead and arsenic are not only dissolved into the soil and but are also sent downstream by runoff from the mines. In addition to soil pollution by waste rocks and heavy metals, the mining activities also cause landslide and erosion. Birmingham Canyon landslide is one of the largest human-induced landslides (Adkins, 2014). The landslide takes place when consistent blasting of the rock leads to the reactivation of pre-existing fracture of rocks. In combating the pollution by heavy metals and waste rock, United States Environmental Protection Agency (EPA) has initiated the Superfund program. Superfund program is established to clean and improve the polluted soil and water by hazardous materials that pose risks to humans and environment. However, the conflict of interest shown by the government agency has weakened the effectiveness of Superfund program to mitigate the negative impacts of Bingham Canyon mining activities on soil quality (“Are we cleaning up”,
