The concerns of Water Pollution In Africa

The concerns of Water Pollution In AfricaWater taint has become a serious line of work in every country in the world. Urban growth, climate change, growing population, investments in agriculture, industrial development, and economic growth have increased the demand for irrigate. immanent and manmade disasters have increased pollution risks in nowadayss environment. Contamination of land, air and piss is challenging the health of humans, plants, animals and other lifetime organisms. Governments worldwide argon burdened with mounting healthcare costs which is diverting investment capital away from economic development public sector projects.The report will discuss issues on irrigate pollution problems which countries in the African continent are facing. Sources of water pollution, water contamination impacts on health, environmental damages, and strategies necessary for reducing or eliminating water pollution would be discussed. I. WATER SUPPLY IN AFRICA a. Water Supply and Wa ter Demand i. Supply Source RainfallAverage annual rainfall in mho Africa is recorded to be 450 mm per year. Rainfall varies between one location to another in South Africa some regions receiving heavy rainfall and others enter low amount of rainfall. For example, good deal living along the coastal regions to the west of South Africa enjoy an annual fair rainfall of 1000 mm. But regions in the north west receive very poor annual rainfall at less than 100 mm as reported by the unite Nations Educational Scientific and Cultural Organization (UNESCO) in 2006. Rivers which are seasonal in nature have water only during the rainy seasons and they remain wry most times throughout the year. The seasonal rivers during rainy days produce excess full point of water. The government of South Africa stores water in dams to meet the give needs for drinking, industrial and agricultural needs throughout the year. South Africa is divided into following nine administrative provinces (12-86) ( Markus Trnqvist and Bjrn fverstrm, tipsiness water fork out in grey Africa with a risk assessment perspective.) Eastern Cape Free State Gautang Kwa Zulu Natal Limpopo Mpumalanga Northern Cape SouthwestProvince Western CapeThe average annual rainfall varies between one province and another. Information listed in Figure-3 illustrates annual rainfall in South Africas provinces as follows (12-86) (Markus Trnqvist and Bjrn fverstrm, Drinking water go forth in Southern Africa with a risk assessment perspective.)ii. Demand Source PopulationAccording to published data by the UNESCO in 2006, South Africas total population is listed to be around 48 million. It is estimated that 59% of the population live in the urban community dwellings. Northern Cap which is the largest administrative province is reported to over 28 million people living in the area which accounts for 37% of South Africas general national population. Due to quick economic growth and development, urbanization is fast g rowing with more and more people moving to metropolitan commercial centers in search of jobs or livelihood. Migration of people from rural areas to urban cities have triggered massive growth in cities businesses, industries, infrastructures, civil defense, internal security, hospitals, and educational institutions etc. As a result of this there folksy settlements have rapidly grown in and around commercial centers within the South Africas administrative provinces. All these growth and development have made water supply management very challenging. Millions of inhabitants living in various cities in each of the nine administrative provinces do not have adequate supply of water. Drainage and sanitation network are overstrained and inadequate to serve the communitys need. in these communities have not access to proper water and sanitation infrastructure. People living in the rural areas wholly depend on groundwater to fulfill or satisfy their needs for water. In South Africa, 19% of people in the overall population do not have access to safe water and over 33% people do not have the bare destiny for basic sanitation services. Over 50 million people in 1994 had suffered miserably without any water supply services. People had no choice chuck out to meet their water demands from rivers, lakes, springs and ponds. Due to the concentrated and focused efforts by the government of South Africa in resource management efficiencies, overall number of people who did not have any water supply during 1994-2004 had dropped to by approximately 40 million (14-86). (Markus Trnqvist and Bjrn fverstrm, Drinking water supply in Southern Africa with a risk assessment perspective.) b. Water Pollution i. Mining Water Pollution Johannesburg which is the largest city in South Africa is on the brink of environmental disaster. on that point is no excavation and recovery process going on in several mines in the area and as a result of this most of these mines today remain closed. Unfort unately toxic water which is flowing out of these mines pollute and contaminate both surface and groundwater. Acid Mine Drainage (AMD) indicates entrapment of toxic water exists in the mines and when the toxic water flows out in a stream it contaminates entire water resources surface water and ground water. Closed mines in Witwatersrand, South Africa stretches from Roodepoort to Boksburg (1-5). (Admin, Sinking Solutions for Mining Water Pollution.)Digging for minerals for years leave big gapping tunnels and hole in the mine. During the mining operation water which collects from ground seepage are pumped out to allow miners to perform their tasks. But when mining operation is suspended for commercial non-viability, water is collected inside and fills-up tunnels and holes deep inside. These water becomes exceedingly contaminated by getting mixed with heavy metal particles from inside the mine. Overflowing toxic mine water becomes dangerous to the environment and contaminates rivers, ponds, lakes and springs along its flow path. Toxic water endangers humans, plants, animals, birds, marine life and the ecosystem with serious healthcare challenges (1-5). (Admin, Sinking Solutions for Mining Water Pollution.)
