Two types of variability are of interest for understanding
and design of treatment wetlands. ... building and moni-

of treatment wetlands have not involved replication; this is
apparently a justiable step.

SUMMARY
Treatment wetlands are consistently effective at reducing ele-

wetlands are overdesigned in terms of TSS reduction,...
