The dewatered material removed from the reed beds will be similar in character to composted sludge with respect to pathogen content and stabilization of organ-ics. The long detention times combined with the final 6-month rest period prior to sludge removal ensure a stable final product for reuse or disposal. If metals are a concern, then a routine monitoring program can track the metals content of the accumulating sludge. In some cases, the metal content may be the basis for sludge removal rather than the volumetric capacity of the bed.
