Fig. 8. Concentrations of fecal coliforms (FC) in leachate from the oxidation pond effluent (OPE)-irrigated lysimeters in relation to Cl^– 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 FC and Cl^– data were available.
