during the active phase of plant operation. Its main use was for drainage of chemicals. Hazardous and exotic chemicals would go down drains in the plant to the pond and later be pumped back to the factory via two large pumps. There it would be distilled to remove

than the pond itself, but enough contamination that it had to be removed. Approximately 10,000 cubic yards (7,600 m) of soil were removed from the surrounding areas. Another 5,400 cubic yards (4,100 m) of soil were excavated from the pond itself.

In
February 2004, the cryogenic system was dismantled, replaced with a temporary thermal foam blanket to keep the soil cold, and the pond was excavated. The soil in the areas surrounding the frozen pond contained lower

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

stabilization system at the waste pond, freezing the soil and groundwater to a depth of approximately 30 feet (9.1 m) around the pond, thereby forming a barrier to groundwater leaching.
