Preliminary results are presented of a multi-authority review of the water pollution hazard represented by 2494 landfill sites in England and Wales. Of these, desk studies indicate that only 51 represent a serious pollution risk to major or minor aquifers. River authorities have classified 80 sites as being unacceptable for future use out of 714 locations they have examined.
In defining provisional guidelines for the selection of landfill sites, a generalized threefold classification of wastes is proposed. A policy of confinement for hazardous wastes is recommended until and unless further research enables adoption of a less rigorous system. A flow diagram is provided for use in site selection.
