Particle-associated microorganisms in stormwater runoff
Water Research, 2003This research investigated the effects of blending and chemical addition before analysis of the concentration of microorganisms in stormwater runoff from a single summer storm to determine whether clumped or particle-associated organisms play a significant role. The standard membrane filtration method was used to enumerate the microorganisms.

Bioremediation of highway stormwater runoff
Desalination, 2009Abstract Emissions of motor vehicles, spilled and released oil, particles of vehicle’s tires as well as substances from asphalt road surfaces represent important source of diffuse pollution in urban environment. During rainfall, these pollutants with various hazardous impacts could be washed off from roads into aquatic environment. The purpose of our

Swale Performance for Stormwater Runoff
Low Impact Development, 2008Swales are “engineered vegetated ditches” that provide stable routing for stormwater runoff. They provide a low-cost drainage option for highways, farms, industrial, and commercial areas. It is reported in the literature that swales mitigate the runoff-carried pollutants, reduce runoff volume, and reduce peak stormwater runoff rate that can damage low ...

Stormwater runoff from highways
Water, Air, and Soil Pollution, 1985During four rain events, stormwater runoff samples from Interstate Highway 95 in Rhode Island were collected and analyzed for petroleum hydrocarbons, 14 polycyclic aromatic hydrocarbons (PAHs) and a variety of trace metals. The concentrations were variable throughout the storm events and some of the components responded similarly and others differently

Causes of toxicity in stormwater runoff from sawmills
Environmental Toxicology and Chemistry, 1999Abstract Samples of stormwater runoff from nine sawmills in British Columbia, Canada, were tested for acute toxicity with juvenile rainbow trout over a 23-month period. Forty-two of the 58 samples tested exhibited toxicity. Causes of toxicity were investigated using toxicity identification evaluation techniques.

Live diatoms as indicators of urban stormwater runoff
Environmental Monitoring and Assessment, 2016Diatom bioassessment of streams/rivers does not distinguish between live (cells with intact chloroplasts) and dead (empty cells) individuals, even though most diatom samples collected from the field will be composed of a mixture of both. This study aimed to evaluate whether percentage of live diatoms (PLD), live diatom density and chlorophyll a, and ...

Stormwater is a continuing problem for both urban and rural areas. Not only does the excess runoff pose a potential flood hazard causing millions of dollars in damage each year, but it also produces environmental degradation in the form of erosion and sedimentation of lakes and streams and the transportation of water pollutants to these same water ...

Temperature dynamics of stormwater runoff in Australia and the USA
Science of The Total Environment, 2016Thermal pollution of surface waters by urban stormwater runoff is an often overlooked by-product of urbanization. Elevated stream temperatures due to an influx of stormwater runoff can be detrimental to stream biota, in particular for cold water systems.

Stormwater runoff to an impaired lake: impacts and solutions
Environmental Monitoring and Assessment, 2015Stormwater runoff can represent a significant source of pollutants to downstream water bodies. An integrated assessment was conducted for the Spring Lake watershed in western Michigan because of concerns that increased impervious land cover in the watershed, especially in sub-basins adjacent to Spring Lake, would result in greater stormwater runoff and

Characterization of urban stormwater runoff
Water Research, 2000Abstract The purpose of this study is to investigate the characteristics of pollutants overflow on storm events, relationships between pollutant load and runoff, and the first flush effect in urban areas. Nine watersheds in the cities of Taejon and Chongju, Korea were selected for sampling and study with different characteristics during the period ...
