Micro-zooplankton grazing as a means of fecal bacteria removal in stormwater BMPs
A priority for environmental managers is control of stormwater runoff pollution, especially fecal microbial pollution. This research was designed to determine if fecal bacterial grazing by micro-zooplankton is a significant control on fecal bacteria in aquatic best management practices (BMPs); if grazing differs between a wet detention pond and a constructed wetland; and if environmental ...

Should I Sweep My Parking Lot When It Rains?
Rain can put a damper on many of your activities. But during the rainy season, a lot of people make the mistake of canceling their regular sweeping services, and this does more harm than good, not only for your parking lot but also the environment. Parking lots are covered with waste, whether you see it or not. There is a lot of chemical waste on your parking lot too. Oil, fuel, grease, metals ...

Can water sensitive urban design systems help to preserve natural channel-forming flow regimes in an urbanised catchment?
Increased stormwater runoff and pollutant loads due to catchment urbanisation bring inevitable impacts on the physical and ecological conditions of environmentally sensitive urban streams. Water sensitive urban design (WSUD) has been recognised as a possible means to minimise these negative impacts. This paper reports on a study that investigated the ability of infiltration-based WSUD systems ...

Modelling and optimization of land use/land cover change in a developing urban catchment
The impacts of land use/cover change (LUCC) on hydrological processes and water resources are mainly reflected in changes in runoff and pollutant variations. Low impact development (LID) technology is utilized as an effective strategy to control urban stormwater runoff and pollution in the urban catchment. In this study, the impact of LUCC on runoff and pollutants in an urbanizing catchment ...

Application of a catchment water quality model for an East–Australian catchment
This paper presents the calibration of a catchment water quality model developed for the continuous simulation of stormwater pollutants from a catchment to the catchment outlet. Calibration of the model was performed using the rainfall and water quality data collected for 'Saltwater Creek Catchment' in Gold Coast, Australia. Runoff estimations from the hydrologic model were compared with ...

Stormwater quality models: performance and sensitivity analysis
The complex nature of pollutant accumulation and washoff, along with high temporal and spatial variations, pose challenges for the development and establishment of accurate and reliable models of the pollution generation process in urban environments. Therefore, the search for reliable stormwater quality models remains an important area of research. Model calibration and sensitivity analysis of ...

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 ...

OSU researchers deploy Stevens equipment in study of green infrastructure treatment for groundwater runoff - Case Study
Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for ...

Using Permeable Eco-Paving to Achieve Improved Water Quality for Urban Pavements
This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically ...

What is stormwater?
Stormwater runoff, water that isn’t absorbed into the ground after a weather event, is a potential water source that cities across the world have struggled with for decades. Why is coping with it such a challenge? Whether the precipitation is water or ice, its addition to the environment can be a problem, especially when a lot of it falls in a short amount of time. When this occurs in ...

How Oil Water Separators Work
Because of the highly damaging effects of oil hydrocarbon pollution on waterways and the environment in general, businesses are required by law to ensure their wastewater and stormwater runoff are pre-treated for oil pollution before entering the sewer system. The first line of oil wastewater treatment is the Oil/Water Separator. Find out how oil/water separators work, what they offer, and how ...

A real-time control strategy for separation of highly polluted storm water based on UV–Vis online measurements – from theory to operation
‘Classical’ real-time control (RTC) strategies in sewer systems are based on water level and flow measurements with the goal of activation of retention volume. The control system rule of ‘clean (storm water) runoff into the receiving water – polluted runoff into the treatment plant’ has been thwarted by rough operating conditions and lack of measurements. Due to the specific boundary conditions ...

New strategies in stormwater-meltwater management in the city of Bergen, Norway
ABSTRACTIn the City of Bergen, Norway, extensive measures against point pollution sources are now to be implemented and to be finished before the end of year 2000, improving the receiving water conditions. Local politicians and public opinion support high standards of receiving water, even higher than the national level. Future improvements in the receiving water quality is planned through ...

Green Water Infrastructure
Stormwater runoff is a major cause of water pollution in urban areas. When rain falls on roofs, streets, and parking lots, the water cannot soak into the ground. In most urban areas, stormwater is drained through engineered collection systems and discharged into nearby waterbodies. The stormwater carries trash, bacteria, heavy metals, and other pollutants from the urban landscape, degrading the ...

What Are Point- and Nonpoint-Source Water Pollution?
Water pollution can come from a single source, or from a variety of sources, a difference that presents challenges in prevention The United States Clean Water Act (CWA) of 1972 made it illegal to discharge any pollutant from a “point source” into navigable waters without a permit. What exactly is point-source pollution? The Environmental Protection Agency describes a point source as ...

Treatment of suspended solids and heavy metals from urban stormwater runoff by a tree box filter
Particulates, inorganic and toxic constituents are the most common pollutants associated with urban stormwater runoff. Heavy metals such as chromium, nickel, copper, zinc, cadmium and lead are found to be in high concentration on paved roads or parking lots due to vehicle emissions. In order to control the rapid increase of pollutant loads in stormwater runoff, the Korean Ministry of ...
