Groundwater is one of the most valuable resources The Ogallala aquifer is the largest aquifer in North America. It runs underground through eight states from Dakota to Texas. What is an aquifer?

as much of the natural gas that can be. As the oil companies were making these oil wells‚ they didn’t take proper precautions to prevent leakage into the groundwater of the places they were in. As a result‚ the groundwater was highly contaminated in places such as Dimock‚ Pennsylvania (where the filmmaker lives). Obviously‚ polluting groundwater that people use to drink breaks many environmental rules set by the government and the Environmental Protection Agency. The people of Dimock and other areas

Modern Agriculture: Its Effects on the Environment Agriculture has been a major component of the United States economy ever since colonial days‚ when 9 out of 10 working persons were employed on a farm. Produclivity of American agriculture has tripled since then‚ and today only 3 percent of our labor force produces enough food and fiber to meet domestic needs as well as supplying about 10 percent of total overseas consumption. This huge increase in efficiency has been the result of many factors

high amount of salt in it‚ like in a salt lake. Secondary salinity is caused by humans. It can be caused by clearing too much land‚ which makes the groundwater rise to the surface and the salts inside dissolve into the soil.Secondary salinity has two main forms of which it happens. The first is dry land salinity; when more water enters the groundwater than is taken out‚ so it can enter vegetation on land and become absorbed by the soil. There is also Irrigation salinity; (Irrigation is the act of

A social constructivist approach is relevant in understanding how knowledge and debates are formulated by differing social groups. Using this theoretical framework provides us with a background on how a technology‚ in this case hydraulic fracturing‚ is constructed through separate discourses. According to Bijker‚ “In the social construction of technology approach (SCOT)‚ relevant social groups are the starting point. Technical artifacts are described through the eyes of the members of these groups

reliance on the Colorado River basin has lead to an overuse of the groundwater‚ eventually threatening the future of the basin. By integrating water conservation methods and education into the everyday curriculum of schools‚ the general population will increase their environmental awareness‚ ultimately conserving more water. Over the past decade the Colorado River basin has seen record lows in surface water levels as well as groundwater levels. “Research by hydrologist James Famiglietti at the University
