In a research project completed on behalf of the UK Environment Agency data was collected data and leachates were sampled from EU landfills that had received imports of MSOR (Mechanically Sorted Organic Refuse) and Mechanical Biological Treatment (MBT) wastes, several years ago. The results of the sampling exercise were analysed for, the presence of trace […]

There are three very important leachate indicator parameters which are used as indicators to identify leachate contamination in any water sample analysed in a water quality laboratory. These three parameters can give an initial guide to anyone investigating what appears to be pollution occurring in the vicinity of a landfill, as to whether the source […]
INTRODUCTION Within the last many years there have actually been major advances in the variety, engineering and control of landfill sites; however it is still a fact that at many sites the generation of very polluting sanitary landfill leachates is still the significant possible environmental problem to be conquered. Although research and experience continue to […]
To the site operator leachate recirculation would certainly appear like commonsense as some of the leachate recirculated will be taken in by the waste and not re-appear. The leachate will gain some treatment – especially a significant reduction in BOD and COD by anaerobic digestion within a methanogenic landfill. In addition, if leachate is being […]
Landfill Leachate Dilute and Disperse Philosophy Landfills in the UK, built before the mid 1980’s were typically designed on a principle of dilute and disperse (EA, 2001/ Brown Book). The location of such sites was chosen so that the attenuation capacity of the underlying strata was sufficient to remediate the impact of the waste mass. […]
A major problem arising from landfills is the discharge of leachate which is formed by water passing through the tip and thus becoming contaminated with various organic and inorganic pollutants. The subsequent movement of the leachate into the surrounding soil, ground water or surface water could lead to severe pollution problems. The mechanisms by which […]
Landfill Operators must watch out for any landfills leachate accumulating in their landfills. This is to avoid finding that large volumes of leachate have collected which may escape and threaten to the local water environment. The solution is given here.
