Stormwater quality benefits of a porous friction course and its effect on pollutant removal by roadside shoulders.
This project has two main objectives; the first is to documents the effect of a porous friction course overlay on the quality of highway stormwater runoff, and the second is to assess pollutant removal of a vegetated area along the side of a road from both conventional and porous pavements. The quantity and quality of stormwater runoff from a four-lane divided highway in the Austin, Texas, area...
متن کاملA Fresh Look at Road Salt: Aquatic Toxicity and Water-Quality Impacts on Local, Regional, and National Scales
A new perspective on the severity of aquatic toxicity impact of road salt was gained by a focused research effort directed at winter runoff periods. Dramatic impacts were observed on local, regional, and national scales. Locally, samples from 7 of 13 Milwaukee, Wisconsin area streams exhibited toxicity in Ceriodaphnia dubia and Pimephales promelas bioassays during road-salt runoff. Another Milw...
متن کاملStormwater Quality Benefits of a Porous Asphalt Overlay
This project documents the impact of a porous asphalt overlay on the quality of highway stormwater runoff. A porous asphalt overlay, also known as a permeable friction course (PFC) or open graded friction course (OGFC), is a layer of porous asphalt approximately 50 mm thick which is often applied on top of conventional asphalt highways to enhance safety and reduce noise. The quality of stormwat...
متن کاملA Study of Chloride and Rhodamine Dye Tracer Movement through an Urban Stream and Raingarden
The University of Georgia (UGA) main campus is dominated by impervious surfaces that produce stormwater runoff during rain events. Campus runoff drains directly into local streams, primarily through storm drains. The effects of organic and inorganic contamination on local streams requires mitigation and management practices, which are regulated by the Athens-Clark County MS4 program (ACC 2015)....
متن کاملEffect of road salt application on seasonal chloride concentrations and toxicity in south-central Indiana streams.
Contemporary information on road salt runoff is needed for management of water resources in regions experiencing urbanization and increased road density. We investigated seasonal Cl(-) concentrations among five streams in south-central Indiana that drained watersheds varying in degree of urbanization and ranging in size from 9.3 to 27 km(2). We also conducted acute toxicity tests with Daphnia p...
