Water Degradation Essay Research Paper Water Degradation

our water ways for use, and replace it with wastes. This leads to nutrification andgeneral deterioration of the water. “Nationwide, there are 2,100 health advisories forfish contaminated by toxic chemicals, according to a 1991 National Academy of Sciencesreport, Seafood Safety.” (Marx, EPA Journal, Sept-Oct, 92) Heated effluent releasedinto river ecosystems are often detrimental. Emissions affect lake and riveracidification and therefore the ability to support aquatic organisms. The effects ofacid rain take a heavy toll on ecosystems whether they are water based or not. Another problem the river ecosystems are facing are exotic species. Somespecies are just naturally occurring incidence, others are human introduced. “Theyhave significantly reduced biological diversity through predation, alteration of habitat,introduction of diseases or parasites and interbreeding with native organisms.”(Stevens, New York Times, Jan. 26, 93) This shows the effects of introducing a foreignspecies to an established habitat. There are a number of factors affecting our riversand ecosystems. Fortunately some conscious effort is being made to preserve thisvaluable resource. These include saving the headwaters of major rivers, replantingriver banks, and government co operative water regulation at dams. An example of the attempts to help our current water situation is Chesapeake Bay where local governments have agreed to reduce the amount of nutrients being released by 40% before the year two thousand. Another form of preservation is the liming of water bodies rivers and entirewatersheds. Liming is the chemical neutralization of acidic waters. By liming theentire watershed, the treatment can last five to ten years. “Harvey Olem saysresearchers have estimated that half the U.S. surface waters acidified by air pollutants will eventually recover under the emissions control strategies most likely to emerge from strengthened Clean Air Act regulations. “The other half will remainacidic,” he observes. And for them “liming may be an option a tool for restoring theirfisheries.”" (Raloff, Science News, Feb 24, 1990) A lot of common practices must soon come to a halt. Obviously we are putting a veryheavy burden on our waterways. The effects of this are very clear. In order to dealwith these problems we must begin at the root of the problem. We must reduce ourwastes and find alternate means for disposal. We must cut back on emissions. Manythings are being done, and acts are being passed. The public population is starting totake it upon themselves to care for their river systems. Fortunately rivers are able,for the most part, to rebuild themselves once the inhibiting factors are removed.
