A landfill site is an area of land that is used to bury waste material.
Due to the decomposition of buried waste material over time, a landfill site presents a potential hazard to the environment unless precautions are taken to contain pollutants and prevent contamination.
Decomposing waste will produce a mixture of flammable and greenhouse house gases that can escape into the local atmosphere. In a landfill site extraction wells are used to collect the landfill gas (LFG) from surround waste at multiple locations around the site. This LFG is then treated and typically used to fuel power generators to provide electricity.
A wide range of harmful liquids are released from waste material as part of the decomposition process, which then mix with rainwater which percolates through the waste. The resulting liquid poses a major contamination risk to the surrounding environment. This polluted water, which is called Leachate, has to be contained within the confines of the landfill site, otherwise it could reach the water table and contaminate water supplies. To prevent leachate escaping a landfill, a membrane lining is buried in the landfill site during construction to create a tank to contain the leachate. Various measurement devices are installed around the landfill site to monitor the leachate and provide feedback to control systems which ensure the integrity of containment.
