polluted water (Ayoade, J. O, 1988; Adebola, 2001). In most homes in the Mui Basin like in most part of Africa as reported by Efe, et al., (2005) valuable man-hours are spent seeking and fetching water, often of doubtful quality, from distant sources. Coal mining has been linked to severe drinking water contamination in many coal mining regions.
communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material.
This causes deforestation, and a loss of biodiversity which has an impact on locals. Another largely ungoverned environmental concern is the pollution caused by mining through leakage and tailings dumping. Tailings are left-over materials from mining and are often dumped in rivers causing metals contamination.

Mercury emissions are very high in South Africa due to coal combustion and gold mining. Air pollutants may contaminate water and soil through atmospheric deposition. However, the major pollution sources for surface waters are the urban and industrial discharges of untreated effluents into the water.
The highest metal contamination was recorded in sediments from the Macalder stream (11075 mg kg −1 Pb), Nairobi mine tailings (76.0 mg kg −1 As) and Mickey tailings (1920 mg kg −1 Hg). Mercury has a long residence time in the environment and this makes its emissions from artisan mining a threat to health.

Arsenic also can be released into groundwater as a result of human activities, such as mining, and from its various uses in industry, in animal feed, as a wood preservative, and as a pesticide. In drinking-water supplies, arsenic poses a problem because it is toxic at low levels and is a known carcinogen.
metal soil contamination. Metals in Soil Mining, manufacturing, and the use of synthetic products (e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge) can result in heavy metal contamination of urban and agricultural soils. Heavy metals also occur naturally, but rarely at toxic levels.

Water pollution control is clearly one of the most critical of those challenges. Without urgent and properly directed action, developing countries face mounting problems of disease, environmental degradation and economic stagnation, as precious water resources become more and more contaminated.

Nov 03, 2012· presentation on water pollution 1. PRESENTATION ON WATER POLLUTION BY MIAN RAHAM GHAFFAR B,es batch 1st 2. Introduction Comprising over 70% of the Earths surface, water is undoubtedly the most precious natural resource that exists on our planet.
The US Environmental Protection Agency (EPA) regulates drinking water quality in public water systems and sets maximum concentration levels for water chemicals and pollutants. Sources of drinking water are subject to contamination and require appropriate treatment to remove disease-causing contaminants.
In Kenya, which has a water dependent economy, the 1997–98 fl oods and the 1999–2000 drought provide a tantalis-ing “what if”. The fl oods cost the country at least USD 870 million, or 11% of GDP; the drought, at least USD 1,4 billion a year, or 16% of GDP. On
are not considered. Impacts resulting from mining is focused on the following topics: • air pollution, • soil contamination, • water pollution and siltation, • geotechnical issues, and • land degradation. Due to Zambia’s long history as a mining nation there are many …
Most mining, milling, and smelting solid wastes, like those discussed in this booklet, are “high-volume, low-hazard” materials that have been exempt from regulation under RCRA. Regulation of high-volume, low-hazard mining wastes is now the primary responsibility of the states. Clean Water Act (CWA)
Water pollution involves the introduction of harmful, poisonous chemicals and other substances into waters (both ground and surface) making them undrinkable. In other words, the contamination of water makes it unsafe for human use. And with the increased rate of water pollution in Africa, so is the availability of clean water becoming limited.
Water quality is also important in ensuring post harvest quality by decreasing decay . Animal Health. It is important that livestock are provided with adequate amounts of quality water, free of contamination. Contaminated water can contain disease-causing organisms which can rapidly spread if animals are drinking from the same trough.

PCBs, MINING, AND WATER POLLUTION Dan W. Bench Region 8 PCB Coordinator U.S. Environmental Protection Agency 999 18th Street Denver, Colorado 80202-2466 ABSTRACT The presence of PCB-containing electrical equipment in underground mines has been documented during US Environmental Protection Agency (EPA), Region 8, mine inspections conducted over the
2005). More recent media reports have drawn attention to mine water pollution contaminating the Loskop Dam, Randfontein and Wonderfontein Spruit areas. Specific water quality problems that are highlighted in the South Africa Environment Outlook Report (DEAT, 2006) include salinity and acidification.
Extracting water through pumping or diversion is a substantial concern in many places, because it can deplete the natural water supply if not managed properly (e.g., groundwater mining). Water quality concerns can arise from extractive industries as well as from various manufacturing and agricultural production processes.
Environmental pollution has many facets, and the resultant health risks include diseases in almost all organ systems. Thus, a chapter on air and water pollution control links with chapters on, for instance, diarrheal diseases (chapter 19), respiratory diseases in children and adults (chapters 25 and 35), cancers (chapter 29), neurological disorders (chapter 32), and cardiovascular disease ...
