ABSTRACT:
The disclosure relates to dump sites for chemical and toxic wastes which avoid the usual problems of chemical pollution of ground water, streams and rivers. Use is made of impacted reinforced concrete tongue and groove sections in sealed relation to the upper surface of a naturally occurring aquaclude which define an enclosed area. Within the enclosed area there are provided a plurality of vertically positioned columns of sand which serve as wicks for collecting liquids. The wicks communicate at the upper ends thereof with gravel windrows leading to a collection pit from which liquids are pumped off for refining and/or recirculation to a chemical plant.
