Stormwater Controls for Pollutant Removal on GDOT Right-of-Way.

摘要

The Georgia Department of Transportation (GDOT) operates a large number of roadside stormwater treatment facilities to contain and treat roadside stormwater runoff. The stormwater best management practices (BMPs) were designed with an emphasis on the removal of suspended solids to reduce the turbidity loading on streams receiving discharge. This investigation was funded to perform monitoring of the stormwater quality leaving currently operating roadside stormwater treatment facilities on GDOT right-of-way. The study objective was to quantify the level of contamination leaving GDOT right-of-way, as well as the change in pollutant levels between the inlet and the outlet of the treatment facilities.
