Synthetic Organic Contaminants (SOCs) are man-made compounds used for a variety of industrial and agricultural purposes. This group of contaminants includes pesticides, PCBs, and dioxin. Synthetic Organic Contaminant health effects include damage to the nervous system, kidneys and cancer risks.
If your water system is a community or non-transient non-community public water system, your water system is required to test for these organic contaminants. Transient water systems do not have to test for these chemicals.
All community and non-transient non-community systems must test each entry point initially for four consecutive quarters.If there are no detections, then they can be reduced to sampling once every three years. For systems serving more than 3300 people, they must submit two consecutive quarterly samples every three years for each entry point. Systems serving less than 3301 are required to submit one sample for each entry point once every three years. This sampling can be eliminated through waivers.
The Maximum Contaminant Levels for the Synthetic Organic Contaminants are listed below.
|Contaminant||Maximum Contaminant Level (MCL)|
|Polychlorinated Biphenyls (PCBs)||0.0005|
Information on waivers can be found in 40 CFR 141.24(h)(5)
