Kepone distribution in the water column of the James River estuary--1976-78.
Concentration of Kepone residues in water collected from the James River estuary in 1976-78 ranged from 0 to 1.20 ppb. The majority of water samples collected showed no detectable residues. Kepone concentrations at the surface and bottom of the water column were similar. Water column residues varied according to seasonal and spatial differences. Levels peaked during the summer months and averaged higher in the middle reach of the estuary. Residues in the water were 1-5 orders of magnitude lower than reported residues in James River bed sediments. There was a significant correlation between water column and underlying bed sediment residues.
