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.

Mercury mobilization in urban stormwater runoff
Science of The Total Environment, 2008Urban stormwater runoff has been identified as a leading cause of waterway impairment for many pollutants, but there has been a lack of research that directly measures Hg in urban stormwater runoff. The objectives of this research were: to use high frequency sampling to characterize the Hg export dynamics from an urban micro-catchment (i.e.

The Importance of Particle Characterization in Stormwater Runoff
Water Environment Research, 2013ABSTRACT: Treatment units for stormwater management are being routinely required for new construction and upgrading of older facilities. This paper shows how particle size distribution affects the removal of sedimentation units and how erroneous results are often obtained if one uses simple overall removal efficiency or if the particle size ...

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 ...

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

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 ...

Quality of Stormwater Runoff from an Urbanised Watershed
Environmental Monitoring and Assessment, 1991A field monitoring network was set up within the Stamford canal watershed in 1989 to study both the quantitative and qualitative aspects of storm runoff from this urbanised catchment. The data acquisition equipment comprised a continuous recording rain gauge, a water level recorder and an automatic water sampler capable of sampling storm runoff at ...

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
