Exploring fecal indicator bacteria in a constructed stormwater wetland
Microbial pollution in surface waters is a concern throughout the world, with both public health and economic implications. One contributing source to such pollution is stormwater runoff, often treated using various types of stormwater control measures. However, relatively little is known regarding microbe sequestration in constructed stormwater wetlands (CSWs), one type of commonly installed ...

Micropollutants in stormwater runoff and combined sewer overflow in the Copenhagen area, Denmark
Stormwater runoff contains a broad range of micropollutants. In Europe a number of these substances are regulated through the Water Framework Directive, which establishes Environmental Quality Standards (EQSs) for surface waters. Knowledge about discharge of these substances through stormwater runoff and combined sewer overflows (CSOs) is essential to ensure compliance with the EQSs. Results from ...

Comparison of the treatment performance of hybrid constructed wetlands treating stormwater runoff
This study was conducted to compare the treatment performance of two hybrid constructed wetlands (CWs) in treating stormwater runoff. The hybrid CWs were composed of a combination of free water surface (FWS) and horizontal subsurface flow (HSSF) CWs. Based on the results, strong correlation exists between potential runoff impacts and stormwater characteristics; however, the low correlations ...

Soakage System - Case Study
Project Description An established local builder purchased land to be developed into 14 housing lots in the heart of Matamata, Waikato - an area with ever-growing demand for residential housing. Installation of a stormwater management system was essential to accommodate the influx of stormwater runoff from the 14 homes. The design required two stormwater modular soakage systems on opposite ends ...

University of Washington portal - Case Study
Active Treatment and Wheel Wash Water Treatment In late 2008 construction began on the 3-year Seattle Light Rail University of Washington link connecting the university with downtown Seattle. Because this site drains to Lake Washington and the Montlake Cut the City of Seattle has put extra emphasis on protecting surface water from contaminated stormwater runoff. In fact, the city routinely ...

Manage Stormwater Runoff with Skimming Technology
When the sky cries, that’s a natural phenomenon. But when Nature’s pure water mixes with various types of oil and hydraulic fluids or other contaminants, the result is a man-made problem. Commonly called stormwater runoff, rainwater will flow wherever it wants once it hits Earth. And this characteristic is what makes water troublesome wherever it encounters oil – in heavy ...

Surface Water / Algae Blooms Case Study
Challenge The city river in Berlin is contaminated to the point that fish death events are common. Combined sewage overflows, stormwater runoff and the high traffic of ships are the main sources of contamination. The high amount of nutrients and the high tempratures in the summer make the river prone to algae blooms. For these reasons, the shore of the river was selected as the first pilot ...

Stormwater runoff plumes observed by SeaWiFS radiometer in the Southern California Bight
Abstract Understanding the factors that influence the incidence and dispersal patterns of freshwater runoff plumes in southern California is important for management of coastal water quality. Significant river discharge is associated with episodic winter rainstorms, leading to turbid pollutant and pathogen-laden stormwater plumes that are clearly visible nearshore in the Southern California ...

Stormwater Management Solutions
Key Points: Rain is the ultimate cleaning agent of our world, but what happens with pollutant-laden stormwater runoff from urban and industrial environments really matters. This article analyzes why stormwater can be harmful, what kind of pollutants it can contain, and how it can affect the environment. After the overview, we will have a quick look at hi-tech solutions that can enable you to run ...

Bioswales reduce contaminants associated with toxicity in urban stormwater
Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering ...

Satellite ocean color observations of stormwater runoff plumes alongthe San Pedro Shelf (southern California) during 1997–2003
Knowledge of freshwater runoff plume dynamics in southern California is important for management of coastal water quality, because river discharge associated with episodic winter rainstorms can be a major source of pollutants and pathogens to coastal waters. The purpose of this study was to analyze the spatio-temporal dynamics of plumes at the San Pedro Shelf in southern California and identify ...

Risks of carbamate and organophosphate pesticide mixtures to salmon in the Pacific Northwest
Salmon populations in the Pacific Northwest are being affected by a variety of environmental stressors including intense fishing pressure, parasites and disease, climatic variability and change, land development, hatchery production, hydropower operations, stormwater runoff, and exposure to toxic contaminants. In recent years, there has been much concern that mixtures of pesticides are causing ...

Impacts of using rainwater tanks on stormwater harvesting and runoff quality
The popularity of rainwater use in Australia depends completely on the individual householder's preference. The quality of reticulated water supplies in major cities of Australia is far superior to water stored in rainwater tanks. However, due to persistent drought and the implementation of stringent water restrictions, cities such as Melbourne have encouraged the use of rainwater harvesting ...

4 Variables That Can Impact the Efficiency of Your Oil/Water Separator
Removing oil from any industrial process is important. Animal fats, grease and petroleum-based oils all have a significant impact on both overall maintenance and environmental compliance of an operation. Hence why oil refineries, chemical plants, steel mills and many other types of companies throughout the world use oil/water separators. This flow-through device takes advantage of the fact ...

Train derailment prompts contaminated land investigation - Case study
On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

Great American Outdoors Act Provides Billions of Dollars for Overdue Repairs and Maintenance of U.S. National Parks
Congress recently passed the most significant piece of land conservation legislation in a generation. The Great American Outdoors Act (GAOA)—a rare bipartisan effort—will provide full funding for the Land and Water Conservation Fund at $900 million annually and will put $9.5 billion over the next five years toward the deferred maintenance backlog on public lands. The GAOA provides ...

High steel facility, Lancaster, PA - Case Study
The Presto Geosystems Geoweb® Load Support System provided a low-maintenance, permeable load-support surface at a staging area for a 10-acre industrial yard site. Heavy traffic at the steel fabricator’s facility caused severe rutting of the existing gravel surface and costly long-term maintenance problems. Design Criteria Provide a permeable surface to control storm water runoff. ...
