The objective of this study was to evaluate aerobic waste treatment plants as breeding sites for nematodes and to locate the unit processes and operations favorable for such breeding. The Urbana‐ Champaign (Illinois) Sanitary District waste treatment plant was chosen for this study. This plant uses the two processes, trickling‐filter and activated‐ sludge units, to treat the same domestic waste. This arrangement made possible a comparative evaluation of these two processes as nematode breeding sites. Furthermore, previous studies of the origin of the nematode population found in the Boneyard‐Saline Branch Drainage System were of assistance in estimating the relative contribution of nematodes discharged by the treatment plant. The nematode population at various locations within the treatment plant was monitored weekly from September 1962 to mid‐ September 1963.
