MONITORING WATER POLLUTION

Monitoring Water Pollution

Monitoring and Assessing Water Pollution

Introduction

There are many of the human activities which unintentionally add phosphorous and nitrogen along with other pollutants with the surface of water. Over decades, the farming, industry development and man-made pollutant, including sewage from business and homes have been pushed for disposal into the water which results in declining the health of streams and rivers. Water pollution has now become a great issue for the world. Many of today's water ecosystems and the drinking water are being polluted and destroyed (Cairns,1973 .Pp.149- 158). There lie many of the water ecosystem types such as, rivers, oceans, ponds and lakes which are giving birth to various organisms (Kennish, 1992, n.d). There lie several overwhelming factors which result in the problem of water pollution such as radioactive waste, sewage, improper trash disposal and the careless beachgoers. All of these are those significant problems that people failed to recognize until the damage is done. Only few of the methods are provided for the control of this pollution where more advanced ways of need to be developed for controlling these problems immediately. This study is an in-depth analysis of the reasons and sources of aquatic pollutants and provides methodologies of monitoring these aquatic pollutants (Miller et.al, 2011 , pp. 532). It will also describe various methodologies which use a particular group of organisms in monitoring the quality of water.

Discussion

Assessment of the quality of water bodies and watercourses can be carried out using physical, chemical and biological methods. Biological methods of evaluation is characteristic of the aquatic ecosystem at the plant and animal populations of the reservoir.

Stressing the importance of bioindicative research methods, it should be noted that Bioindication involves the identification of the actually occurring or environmental contamination on the functional characteristics of individuals and the ecological characteristics of communities of organisms. Gradual changes in the species composition of the same form as a result of long-term poisoning of the reservoir, and they become apparent in the case in the event of far-reaching changes.

Thus, the species composition of living organisms contaminate the water body is the final characteristic of the toxicological properties of the water environment for a certain period of time and does not give its assessment at the time of the study.

Sources of water pollution

Water pollution comes from many sources. Following is a summary of some of the major causes. There lie many of the causes that result in contamination of water but two of the general categories include; direct and indirect contaminant sources (Miller, 1994, Pp. 254).

All of the direct sources possess those contaminant wastes which directly come from the sewage outfalls from the factories, waste plants and refiners. This emission of fluids directly goes into the water supplies of urban. In states like U.K and U.S, all such practices are regulated; however, this doesn't mean that water pollutants are not possible to found in these waters.

There even lie various indirect sources in contaminating the water. This includes those contaminants that enter water supply through ...
