The effectiveness of an in-series surface flow constructed wetland des
igned to treat landfill leachate was determined by conducting pollutan
t removal efficiency studies over a 4 month period. The first step in
the study involved the characterization of the leachate generated with
in the landfill. At the same time, ten in-series parallel wetlands wit
h a 10:1 length to aspect ratio were constructed, with each cell desig
ned for a maximum water depth of 0.5m. Cells were planted with a varie
ty of vascular aquatic plants including Sagittaria spp., Pontedaria sp
., Scirpus spp., Phragmities sp., Typha sp., Juncus spp., and Zizaniop
sis sp.. This system is a component of a solid waste facility of a clo
sed-loop design incorporating recycling, composting and constructed we
tlands to treat leachate mixed with septage on site. The system is cha
racterized by a varying hydraulic loading rate and retention time.
