PCB’s are polychlorinated biphenyls which are manufactured organic chemicals that contain 209 individual chlorinated chemicals that are known as congeners. They are man-made materials that have been in use since the 1930s but they were banned by the federal government in 1976. The announcement of the EPA about the fish in Lake Hartwell sank businesses overnight, campers left campsites around the lake, and swimmers found other places to swim in. The visitation to the lake was decreased by half after the EPA announcement, and a $1 billion class-action law suit was launched which was bait-shop owners against Sangamo. Over $100,000 million has been spent on the cleanup of Lake Hartwell but the cleanup will still take decades to come. The water was still being drunk by people though because environmental engineers said that PCB’s cling to sediment, and the EPA added the Sangamo plant to its national priority list in 1990. PCB’s decay at different rates because they depend on the amount of chlorine in them, and the long-term effects of them are not fully understood which is why
