Fig. 7. Concentrations of fecal coliforms (FC) and fecal streptococci (FS) in leachate from the oxidation pond effluent (OPE)-irrigated lysimeters in relation to the carbonaceous biochemical oxygen demand (CBOD) concentration in the leachate. Data are from all sand- and soil-packed, unplanted (at LF 1), and Eucalyptus planted lysimeters (at LF 0.2 and intermittent leaching), and from all the sampling events where both bacteria (FC and/or FS) and CBOD data were available.
