A blog about Landfill Construction Quality Assurance
European Directives Arguably, the most important European legislation relevant to landfill containment is embodied within the Council Directive of 17 December 1979 on the protection of groundwater against pollution caused by certain dangerous substances (80/68/EEC) (CEC 1979). The Annex to this Directive contains two lists of generic as well as specific compounds or substances. List [...]
Landfill operators everywhere must be prepared to give a thorough demonstration that their practices are environmentally sound, or they will lose public support as rising local awareness of environmental quality develops.
The most critical components of a landfill closure cap are the barrier layer and the drainage layer. The barrier (sealing) layer can be low-permeability soil (clay) and/or made from geosynthetic clay liners (GCLs).
The choice of Geosynthetic Clay Liner (GCL) may be a great option when the more normal Compacted Clay Liner (CCL) option is expensive or is not readily available in a region. Read about GCLs here!

Those involved with the design, construction, operation and closure of potable water and irrigation ponds, floating covers, canals, landfills, waste water lagoons, secondary containment, golf course ponds, decorative applications, corrective action activities at closed sites, etc. are encouraged to attend.
