Edward Clarke 13PM With Reference to examples, compare and contrast the problems associated with water quality between MEDCs and LEDCs. There are many causes of water pollution. These range from crisp packets and other litter, to industrial waste containing dangerous chemicals. Because of the ranges of causes, there is also a massive variety in the problems associated with it. One of the main problems is its damaging effect on the environment. Pollution damages whole ecosystems and can cause a river to become 'dead' - killing all life in it. The pollution also causes aesthetic damage, often turning pleasant riversides into dirty eyesores with unpleasant smells. Pollution, especially in the form of dangerous chemicals can also pose serious health risks to the surrounding population. Tourism can also be affected causing the loss of jobs and political problems can arise in regards to legislation and the introduction of clear-up schemes. The problems encountered and the scale of them varies between the MEDW and the LEDW. The problems in the MEDW are related to the industrial practices that take place along the riverbanks. ...read more.


A project is also being implemented with funding from the Global Environmental Facility (GEF). It is the Manzala engineered wetland project which aims at cleaning up the Nile water before it flows into the Mediterranean Sea. Another important project financed by GEF is the coastal clean-up project of the Red Sea. Coral reef and tourist areas are to be protected by this project from oil spills from Egyptian oil fields and the tankers passing through the Suez Canal. Regulations have also been made which include Laws 48 (1982) and Law 93 (1962). These laws address the protection of the Nile and its waterways from pollution, and regulate the discharge of wastewater into the sewerage system. As recently as the 1960s, the Thames was biologically 'dead' - only a few bacteria and tubifex worms could live in the polluted waters. Since then, considerable investment in waste water treatment and the decline of the manufacturing industry have caused a dramatic improvement in the river environment. The quality of the water in the River Thames is better now than at any time in the last century and the Thames is now the cleanest metropolitan estuary in the whole of Europe. ...read more.


As the monitoring of the Sandoz chemicals continued, more chemicals were discovered and it emerged that many different companies were discharging chemicals unlawfully. BASF, well known for their recording tapes, admitted to spilling 1100kg of herbicide, Hoechst admitted to a major leak of chlorobenzene, and Lonza confessed that they had lost 4,500 litres of chemicals from their plant. Despite this worrying state over 20 million people were, and still are, getting their drinking water from the Rhine. Figure 2 Water Pollution - smells like trouble to me The main similarity between schemes tackling water pollution in the developed world and the less developed world is that they both try and eradicate the pollution at its source and also try to educate people about the problems associated with water pollution and how to dispose of their rubbish properly. The difference is the amount of money ploughed into correcting the problem. Although the Indian and Egyptian governments have initiated some schemes of action, they do not have the financial power to match the British and German Governments in their clear up operations. They have to receive help from the World Banks and other aid organisations. ...read more.
