Organic contaminants

BACKGROUND

Organic contaminants are generally found in trace amounts in ground and surface waters and may pose serious threats to human health. Common sources of organic pollutants include industrial activities that inadvertently leach chemical runoff into surface waters. Exposure to organic contaminants such as polychlorinated biphenyls (PCBs) and vinyl chloride in drinking water has been associated with a range of adverse health effects, including cancer, immune deficiencies and nervous system difficulties. Activated carbon filters are effective in removing these and other harmful chemical substances.
