Landfills
1. Sanitary landfills are disposal sites for non-hazardous solid wastes spread in layers, compacted to the smallest practical volume, and covered by material applied at the end of each operating day. 2.
Landfills Too Tightly Packed for Most Trash to Biodegrade
Most landfills are fundamentally anaerobic because they are compacted so tightly, and thus do not let much air in. As such, any biodegradation that does take place does so very slowly.

Examples include the oceans, plants and landfills. Carbon Tax A tax on emissions of coal, oil and natural gas. Its intent is to reduce the amount of emissions produced annually. Carcinogen Any substance known to promote cancer.
Leaching As water moves through soils or landfills, chemicals in the soil may dissolve in the water thereby contaminating the groundwater. This is called leaching.
landfill Facility in which solid waste from municipal and/or industrial sources is disposed; sanitary landfills are those that are operated in accordance with environmental protection standards.

Paper products are the largest component of municipal solid waste, making up 31-38% of the composition of landfills in the United States.
Animal agriculture, manure, natural gas, rice paddies, landfills, coal, and other anthropogenic sources contribute about 450 million tons of methane each year according to TAR [13].

Leachate A liquid generated in landfills. It is the result of water seeping into and through the wastes. As the water contacts the waste materials it dissolves part of the organic and inorganic matter contained in the landfill.

Under current regulations, landfills are required to have liners and leachate treatment systems to prevent contamination of ground water and surface waters. An industrial landfill disposes of non-hazardous industrial wastes.

Recycle - Process by which a material is diverted from landfills and instead reprocessed into a new product. It is the third R in the Three R's process; products which are recyclable are marked with the recycle symbol.
Recycling reduces the need for landfills and other disposal facilities, thereby allowing local lands to be used in more environmentally preferable ways. Recycling is a very important thing to do so that we can help our environment.

Point Source Contamination: water contamination from specific sources such as leaking underground storage tanks, landfills, industrial waste discharge points, or chemical mixing sites.
Leachate - Water that collects contaminants as it trickles through wastes, pesticides or fertilizers. Leaching may occur in farming areas, feed lots, and landfills, and may result in hazardous substances entering surface water, ground water, ...
