Water Pollution
We tend to think of water in terms of a particular purpose: is the quality of the water good enough for the use we want to make of it? Water is fit for our own use but may be unfit for another's. We may, for instance, trust the quality of lake water enough to swim in it, but not enough to drink it. Along the same lines, drinking water can be used for irrigation, but water used for irrigation may not meet drinking water standards. It is the quality of the water, which determines its uses.There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. Direct sources include sewage outfalls from factories, refineries, waste treatment plants etc. that emit fluids of varying quality directly into urban water supplies. In the United States and other countries, these practices are regulated, although this doesn't mean that pollutants can't be found in these waters. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere by means of rainwater. Soils and ground waters contain the remains of human agricultural practices (fertilizers, pesticides, etc.) and improperly disposed of indust
2. Russia Oil Spill, http://www.american.edu/td/komi.htm The oil spill near the town of Usinsk in Northern Russia (Komi republic) is one of the most serious environmental disasters of the decade. The pipeline just south of the Arctic Circle had been leaking since February 1994 but the oil was contained within a dike built for this purpose. On October 1st, the dike collapsed because of cold and snow. Following the collapse, around 102,000 tones of oil began to pour onto the Siberian tundra. The spill reached the Kolva River, a tributary of the Pechora River, which falls into the Barents Sea. Life within the rivers as well as the fragile environment of the Artic have been endangered by this oil spill. Experts estimate the spill to be eight times greater than the Exxon Valdez oil spill. This example is only one kind of pollution that we as humans cause to the environment. 4.
