Sediment Contamination. The bottom of streams, rivers, lakes, ponds, mudflats, and even oceans is made up of materials that were deposited there by the natural forces of currents (a constant flow of water in a predominant direction), gravity (attraction between two .
Some cadmium compounds are able to leach through soils to ground water. When cadmium compounds do bind to the sediments of rivers, they can be more easily bioaccumulated or redissolved when sediments are disturbed, such as during flooding. Its tendency to accumulate in aquatic life is great in some species, low in others.
Cadmium in food Cadmium (Cd) is a heavy metal found as an environmental contaminant, both through natural occurrence and from industrial and agricultural sources. Foodstuffs are the main source of cadmium exposure for the nonsmoking general population.
State Superfund Program. The State Superfund Program oversees and provides funding for the remediation of contaminated sites. The use of State funds for remediation at hazardous waste sites is determined by calculating a superfund priority score in accordance with Regulations of Connecticut State Agencies (RCSA) Sec. 22a133f1.
