Table 3: Concentration and total fecal coliform colony-forming units (CFUs) in runoff.
Mean CFUs in 100 mL
Mean total CFUs‡
LBU: low rate of biosolids, unfiltered; LBF: low rate of biosolids, filtered by a 1 m grass strip; HBF: high rate of biosolids, filtered by a 1 m grass strip; C: untreated control. Mean CFUs are given, but no differences among treatments were detected using preplanned orthogonal contrasts on raw, square-root, or log10 transformed data.
