Groundwater Pollution and Drinking Water Scarcity Essay example

Good Essays

"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 nation's groundwater resources. Groundwater resources make up a minute 0.31% of the world's 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. Household productes, many of which contain
