Fracking is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. A well is dug a mile or two into the ground and lined with cement. Each gas well requires an average of 400 tanker trucks to carry water and supplies to and from the site. (2) Each fracking job can take anywhere from one to eight million gallons of water. The water is mixed with sand and chemicals to create fracking fluid. About 40‚000 gallons

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such

Besides being beneficial to your health‚ organic food has a positive impact on the environment. Farming organic food allows for less groundwater to become contaminated that in the process of farming conventional crops. This is because organic crops are never exposed to harmful chemicals that can seep into the ground and

Abstract Water is a finite resource which means that the total amount of water in the planet is only limited. Its supply remains the same and yet human population recently grows resulting to a decrease of available amount of freshwater per person. The relatively small amount of available freshwater elaborates on how critical it is for everyone to help preserve and maintain clean‚ healthy lakes and streams‚ our sources of water. Water is mostly now being wasted because it is under-priced. We do not

government does not provide a solution. The Texas legislature should ban or minimize fracking in specific areas of Texas‚ which includes Forth Worth where there are 12‚000 fracking wells. The reasons are because fracking causes contamination in groundwater and the atmosphere‚ uses chemicals that are unsafe and toxic‚ causes health risks to many residents‚ and causes earthquakes.
