Partial correlations between concentrations of water-soluble nutrients and water-soluble organic carbon (W.S.O.C.) after filtration (0.22-μm pore size), and for turbidity, with log₁₀-transformed concentrations of total coliforms, E. coli O157:H7 strain B6914, and total heterotrophs in leachate over 18 days^a

^aAnalysis of variance using SAS proc GLM; soil type, column type, and manure application were class variables. Significant correlations (P < 0.05) are listed in boldface. 

^bConcentrations of total coliforms and E. coli O157:H7 strain B6914 correlated with concentrations of nitrate, ammonium, and phosphate, not with concentrations of W.S.O.C. or with turbidity in leachate. Total coliforms and total heterotrophs correlated only with nitrate and phosphate in leachate.
