A waste pond or chemical pond is a small impounded water body used for the disposal of water pollutants, and sometimes utilized as a method of recycling or decomposing toxic substances. Such waste ponds may be used for regular disposal of pollutant materials or may be used as upset receivers for special pollution events. Often, chemical ponds themselves are addressed for cleanup action after their useful life is over or when a risk of groundwater contamination arises. Contamination of waterways and groundwater can be damaging to human, animal and environmental health. These health effects bring into question the best engineering solutions to mitigate waste ponds' environmental impact.
