Polychlorinated biphenyl contamination of areas surrounding two transformer salvage companies, Colman, South Dakota, September 1977
Soil, corn plants, and foliage from areas surrounding two electrical salvage companies involved in reconditioning old transformers had unusually high levels of polychlorinated biphenyls. Levels decreased as distance from the factories increased. PCBs were dispersed into the air through incineration of waste oils; water and soil contamination was caused by runoff from the factories. PCBs found in the contaminated areas closely resembled Aroclor 1260 as did the PCBs in the waste oil, wherease PCBs in other areas were more similar to Aroclor 1254. PCBs on surface soils taken from an unplowed pasture near the factories also resembled Aroclor 1260, whereas samples taken from depths of 2 to 4 inches showed degradation of some PCB isomers. PCB concentrations in corn cobs and kernels were < 0.05 ppM, whereas leaves contained PCB levels of up to 2.2 ppM. PCB levels in earthworms and small rodents collected near the factories were considerably higher than levels in the same types of animals collected from other areas.
