Best management practices - effectiveness of retention/detention ponds for control of contaminants in highway runoff. Final report, January 1983-August 1986

Technical Report ·
OSTI ID:6158120
; ; ;
The fate of nutrients and heavy metals in highway runoff entering retention/detention ponds was studied. Investigations on characterization of highway runoff, water quality in receiving ponds and surrounding drainage basins, isolation chamber studies, accumulation of contaminants by bottom sediments, speciation of heavy metals in the sediments, release studies under various pH and redox potential and groundwater monitoring surrounding the pond area were carried out in two sites at Maitland Interchange and EPCOT Interchange located in Orange County, Central Florida. Removal efficiencies of nitrogen, phosphorus and heavy metals in a well-established pond operating for 7-8 years at Maitland site and a newly constructed pond at EPCOT site were evaluated. Most of the metals accumulated in the pond sediments are immobile under current conditions of pH and redox potential.
