[13] [14] Feeling pressure to act expeditiously and keep costs down, officials requested in their permit application for the landfill to be waived of three requirements then in place for such a facility's construction: a specified distance from groundwater, the presence of a leachate collection system, and the presence of an artificial liner. [15]
The leachate mixture is sealed in extraction vessel for general analytes, or possibly pressure sealed as in zero-headspace extractions (ZHE) for volatile organic compounds and tumbled for 18 hours to simulate an extended leaching time in the ground. It is then filtered so that only the solution (not the sample) remains and this is then analyzed.
Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
