waste on-site, these may be adapted for the particular site and situation in question. 7.5.1 Communal pit disposal Perhaps the simplest solid waste management system is where consumers dispose of waste directly into a communal pit. The size of this pit will depend on the number of people it serves.

Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate theenvironment. Being the primary source of energy coal has becomeessential to meet the energy demand of a country. It isexcavated by both opencast and underground mining methods andaffects the environment, especially water resources, by discharginghuge amounts of mine water.

Chemicals, waste products and soil that are carried by rain into streams or rivers become a part of NPS. Common examples are fertilizers, herbicides, pesticides, spilled motor oil and wastes from pets, wildlife and livestock. Other significant sources of NPS include: 1. Litter 7.

'overburden' or 'waste rock') that must be moved or excavated to allow access to the ore deposit. The first way in which proposed mining projects differ is the proposed method of moving or excavating the overburden. What follows are brief descriptions of the most common methods. 1.1.3.1 Open-pit mining

• The mining company has been dumping waste or mining waste outside of the mining area or in sensitive areas (such as near rivers or wetlands). Remember that waste could include liquid waste. • There has been an increase of dust in the air, bad smells or smoke. • Dirty water is flowing or being piped directly into rivers, streams or dams.

enhanced through mining and milling processes where oxidation reactions are initiated. Mining increases the exposed surface area of sulfur-bearing rocks allowing for excess acid generation beyond natural buffering capabilities found in host rock and water resources. Collectively the generation of acidity from sulfide weathering is termed Acid

extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often more
