Groundwater Pollution and Drinking Water Scarcity Essay...

We have the ability to provide clean water for every man, woman and child on the Earth. What has been lacking is the collective will to accomplish this. This is the commitment we need to make to the world. Jean-Michel Cousteau The Issue: Recently, the issue of drinking water quality has become a matter of great importance. Hydrogeologists and water resource managers have realized that the increased demand for drinking water, due to population growth, has placed a huge burden on our nations groundwater resources. Groundwater resources make up a minute 0.31% of the worlds water supply. Groundwater quality can be defined in terms of the concentration of its chemical constituents relative to a variety of potential uses.†¦show more content†¦Both of these phenomena occur naturally. The chemical alterations that occur in the soil and atmosphere during the hydrologic cycle are pivotal in maintaining the natural equilibrium. However, due mostly to human intervention, the water is becoming poisoned as it seeps into the Earth. The Science Behind the Issue: The four main types of groundwater pollution are industrial, domestic, agricultural and salt-water intrusion. Industrial pollution reaches aquifers through used waters as I have already briefly explained. Used waters can contain chemical compounds and trace elements like metals at high temperatures. Radioactive pollution from nuclear power plants is also carried by used water, as is rain that infiltrates through waste disposal sites. Pipeline breakage as well as other unforseeable accidents also add to industrial pollution. Irrigation and water carry away fertilizers, minerals, salts, herbicides and pesticides. This activity is known as agricultural pollution, and it causes nitrate levels to rise excessively. Environmental pollution is due in large part to seawater intrusion in coastal aquifers (Fried 1975). Man-made pollution reaches the aquifer by rain and the rain subsequently infiltrates sanitary landfills. Road-runoff and domestic wastewater are non-point sources that also add to groundwater pollution.

Sun Path Chart for Orbital Mechanics- myassignmenthelp.com

Question: Write about theSun Path Chart for Orbital Mechanics. Answer: The maximum angle of the sun above the horizon in my hometown (Ottawa) is 68 degrees. The minimum angle of the sun above the horizon at noon in my hometown is 21 degrees. The number of hours of daylight is 12hours and 9 hours on March 20th and December 21st respectively. The sun is at the maximum height angle (68 degrees) on one day only. That is, on 21st June. According to orbital mechanics, the earth rotates on its orbit while revolving around the sun. The earths ecliptic plane is tilted by 23.5 degrees relative to the earths celestial equator during the summer solstice and 23.5 degrees during the winter solstice. Evidently, the difference between the maximum and minimum angles of the sun above the horizon is 68-21=47 degrees. Meaning the difference is twice the earths tilt (Physical Geography, 2014). However, along with the equator, the difference between the maximum and the minimum angles is equal to the earths tilt. That is 23.5 degrees. Moreover, the equator receives daylight of 12hours from December through June. References Physical Geography. (2014). 6(h). Earth-Sun Geometry.
