Several automatic water quality monitoring stations have been setup in the central Everglades of Florida to mornitor water quality on site continously with multiple probes, and automatically collect water samples with flow-proportional sampling techniques in canals to determine total- and ortho-P. Water grab samples and core sediment samples were also collected from those corresponding sites to assess P concentrations and its distribution. The result showed that water quality from wetlands was far more better than that from canals. The concentration of P in the sediments is closely related to that in the water, which may also play an important role to affect water P concentration. Approximately two-year data has displayed that the total-P in wetlands has shown a promising result to meet the requirement of the Everglades restoration criterion (10 ppb) if terminate or modify some canals along with levees because canal is a main carrier and contributor to impact water P concentration in the wetland. The presentation demonstrates an overview for setup an automatic water quality monitoring station, equipment required, programing on water quality monitoring, flow-proportional sampling, application of telecommunication systems, water quality results associate with sediments, problem and prospects in Everglades restoration of Florida.
