Water pollution usually occurs when a water body gets contaminated by different materials which are usually not present in it and which are harmful in nature. So in such a situation the water body is no longer useful for its intended use and hence is termed as polluted. If we consider the case of pollutants, there are two variants of water pollution. They are called as point source and non point source. Point sources of pollution happen when harmful substances are emitted directly in the water body and non point sources are those which deliver pollutants indirectly usually through environmental effects. It is generally regarded that water pollution which arises from non point sources are usually difficult to deal and ironically these are the ones which account for a majority of the contaminants in water bodies like streams and lakes. In order to understand the whole scenario clearly lets give a brief introduction to causes of pollution. We all know that there are many elements which cause pollution. Some of the important ones are sewage and fertilizers. These are dangerous because they contain nutrients like nitrates and phosphates. The main problem is that these nutrients stimulate the growth of aquatic plants and excessive growth of these organisms clogs the waterways. They also block light to the deeper section of the water body and this affects fish and other living organisms. Pollution is also caused when silt and other suspended solids, such as soil, construction and logging sites, urban areas, and eroded river banks when it rains. Normally, lakes, rivers, and other water bodies undergo Eutrophication, an aging process that slowly fills in the water body with sediment and organic matter. When these sediments enter various bodies of water, fish respiration becomes impaired, plant productivity and water depth become reduced, and aquatic organisms and their environments become suffocated. Now that we mentioned about the various ways in which water pollution lets also mention the sources of water pollution before we go in to the specifics of water pollution with reference to Ireland. Normally there are three major sources of water pollution. They are Municipal, Industrial and Agricultural. Of these municipal sources are of paramount importance while dealing with the specifics of the assignment.Municipal water pollution consists of waste water from homes and commercial establishments. The main goal of treating municipal
wastewater was simply to reduce its content of suspended solids, oxygen-demanding materials, dissolved inorganic compounds, and harmful bacteria. In recent years, however, more stress has been placed on improving means of disposal of the solid residues from the municipal treatment processes.
Water Pollution in Ireland
It is generally perceived Ireland to be a land laden with greenery, rivers and lakes. This in fact helps people of Ireland to promote it as tourist destination. One basic fact that Ireland did not experience pollution in other forms is that Ireland remained agriculturally dominant country even during the industrial revolution thereby making it a safe destination in British Isles. However Ireland is facing crisis regarding its environmental outlook as recent trends and statistics have shown that upcoming industrial
