Liquid (mainly water) that percolates through a landfill and has picked up dissolved, suspended, and/or microbial contaminants from the waste. Leachate can be compared to coffee: water that has percolated down through the ground coffee.
Leachate is rainwater that seeps through the landfill and becomes contaminated. If not contained and managed properly, leachate can get into our waterways, coastal areas and ground water, polluting them.
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. If this leachate is allowed to exit the bottom of the landfill, it will carry contaminants to the groundwater and/or adjoining surface water.
occurs when precipitation seeps through a landfill and mixes with toxic and nontoxic liquids, some of which are created during biological decomposition sanitary landfill usually has a leachate collection system where leachate is collected from the landfill and treated to prevent the contamination of ground water.
liquid (which may be partly produced by deromposition of organic matter) that has seeped through a landfill or a compost pile and has accumulated bacteria and other possibly harmful dissolved or suspended materials. If uncontrolled, leachate can contaminate both groundwater and surface water.
the liquid solution released by, or percolated through, porous waste material (such as refuse in a landfill or mining tailings) and containing dissolved and/or suspended chemical constituents, some of which may be hazardous. elanoma: a condition of malignant skin cancer.
A liquid that results from water collecting contaminants as it trickles through wastes, agricultural pesticides or fertilizers. Leaching may occur in farming areas, feedlots, and landfills, and may result in hazardous substances entering surface water, ground water, or soil.
The solution produced by passing a liquid through a solid, often containing chemicals that have dissolved from the solid to the liquid. As rainwater passes through landfills and associated sediments, various chemical substances may dissolve in the water and penetrate the aquifer and contaminate ground water.
water that is contaminated as it trickles through waste, agricultural pesticides or fertilizers. In land disposal sites, leachate is formed when moisture percolates through layers of waste and dissolves and carries away various chemicals.
Liquid that passes through, and escapes from, a landfill. The liquid is created from the rainfall and liquids present in the deposited waste that percolates down through the soil and garbage carrying many toxins with it as it travels to areas surrounding the landfill.
Any substance that has undergone leaching - i.e., the dissolving out of soluble parts from, for example, ashes, ores, or other matter - by running water or other liquid through slowly; a substance subjected to the action of percolated water. The contaminated water or leachate in landfill sites is a complex, highly variable mixture, consisting of various organic and inorganic compounds and microorganisms. It is generated by precipitation or by other moisture that enters the landfill from the breakdown of organic matter or from ground water. It is generally characterized by a strong odour and dark brown colour and contains high levels of pollutants.
Liquids that have come in contact with waste. Leachate accumulates in the waste footprint of the landfill. Leachate levels within the landfill must be monitored and cannot exceed state regulatory agency established levels. Depending upon the site, there are different ways to handle collected leachate. Some of these include: Collecting it in tanks and periodically transporting it off-site for treatment and disposal; Collecting it in evaporation ponds which allow it to naturally evaporate into the air; Discharging it into the sewer system, Re-circulating it back into the landfill to aid in the biodegradation of the waste.
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, or soil.
Liquid produced as part of natural decomposition in landfills, which percolates down through the waste. This liquid, which is water-based, can be pumped up and fed back into landfills to further aid decomposition.
liquid that has been generated by solid waste decomposition and which has extracted, dissolved or suspended materials in it. The leachate from a compost bin or worm bin is full of nutrients and is an excellent liquid fertilizer. !-- google_ad_client = "pub-5534775256628426"; google_ad_width = 728; google_ad_height = 90; google_ad_format = "728x90_as"; google_ad_channel =""; google_color_border = "A8DDA0"; google_color_bg = "EBFFED"; google_color_link = "0000CC"; google_color_url = "008000"; google_color_text = "6F6F6F";
A solution or product obtained by percolating liquie (such as water) in order to separate soluble components of a mixture or ore. Time needed to plan and construct a facility, including the time required to obtain government approval, carry ou environmental assessment, etc.
Liquid that collects contaminants as it percolates through or drains from solid waste, pesticides or fertilizers. Leachate often contains suspended or dissolved waste materials and may occur in farming areas, feedlots, and landfills. Leaching may result in hazardous substances entering surface water, ground water, or soil if it is not controlled.
Leachate is the liquid produced when water percolates through any permeable material. It can contain either dissolved or suspended material, or usually both. This liquid is most commonly found in association with landfills where result of rain percolating through the waste and reacting with the products of decomposition, chemicals and other materials in the waste to produce the leachate.
