Surface water Sulfate dynamics in the northern Florida everglades
Received for publication August 24, 2007. Sulfate contamination has been identified as a serious environmental issue in the Everglades ecosystem. However, it has received less attention compared to P enrichment. Sulfate enters the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of ...

Contribution of trace metals from atmospheric deposition to stormwater runoff in a small impervious urban catchment
The contribution of atmospheric deposition to emissions of trace metals in stormwater runoff was investigated by quantifying wet and dry deposition fluxes and stormwater discharges within a small, highly impervious urban catchment in Los Angeles. At the beginning of the dry season in spring 2003, dry deposition measurements of chromium, copper, lead, nickel, and zinc were made monthly for 1 ...

The development of a novel approach for assessment of the first flush in urban stormwater discharges
The management of stormwater pollution has placed particular emphasis on the first flush phenomenon. However, definition and current methods of analyses of the phenomena contain serious limitations, the most important being their inability to capture a possible impact of the event size (total event volume) on the first flush. This paper presents the development of a novel approach in defining and ...

Project - 1 Grosvenor Square, London
Project Description Situated on one of London’s most iconic sites close to Buckingham Palace and marketed as Europe’s most desirable real estate, No.1 Grosvenor Square comprises 44 luxurious residences, a gym, 25m swimming pool, spa and cinema. An Aqua-lity Storm Control (ASC) system utilises StormHarvester’s technology to turn the 125,000L rainwater harvesting tank into an ...

Shoreline erosion and stormwater management project case study
In early August, 2007, a homeowner on Lake Waubesa near Madison, Wisconsin contacted Agrecol Corporation about their Envirolok Vegetated Retaining Wall System. The homeowner wanted to replace a failing lake wall with an environmentally-friendly shoreline. The old wall was built with creosote railroad ties which was just one of many stormwater management problems with the project site. A ...

Influence of the land use pattern on the concentrations and fluxes of priority pollutants in urban stormwater
This paper presents the results of the concentrations (μg/L) and fluxes (g/ha) of priority substances in stormwater from three watersheds with different land use patterns (namely, residential, urban dense, high urban density). Samples were collected at the outlet of these watersheds. Thirteen chemical groups were investigated corresponding to 88 individual substances before treatment. Results ...

Airport deicing effluent treatment and regulatory guidelines
Airport and airplane deicing is employed with the use of brines, salts, alcohols or glycols to remove and prevent or delay the formation of snow and ice. In the United States (US), the Federal Aviation Administration requires airlines that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement (USEPA 2011a). These deicing operations use large amounts ...

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 ...

Spatial pattern analysis for water quality in free-surface constructed wetland
Free-surface constructed wetlands are known as a low-energy green technique to highly decrease a wide range of pollutants in wastewater and stormwater before discharge into natural water. In this study, two spatial analyses, principal factor analysis and hierarchical cluster analysis (HACA), were employed to interpret the effect of wetland on the water quality variables (WQVs) and to classify ...

North Carolina wal mart - Case Study
Passive Pre-Treatment with ChitoVan Cartridges Followed by CESF with 1.5% ChitoVan Two Chitosan-Enhanced Sand Filtration systems where implemented during the construction of a Wal-Mart Superstore and Sam's Club near Raleigh, NC. The treatment train consisted of a series of ponds with conveyance channels that utilized ChitoVan Chitosan Lactate Cartridges for treatment prior to being filtered. ...

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 ...

Assessment of urbanization/impervious effects on water quality in the urban river Annaba (Eastern Algeria) using physicochemical parameters
Surface water quality is deteriorating due to the increase of urbanization which increases the load of stormwater and wastewater discharged into rivers. To evaluate the quality of an urban river (Annaba, northeastern Algeria), multivariate statistical analyses were applied to the physicochemical measures of 38 parameters. The application of principal component analysis and factor analysis ...

TMDL support activities for the Anacostia river case study
States and EPA are required to establish Total Maximum Daily Loads (TMDLs) for waterways that fail to support their designated uses (e.g., swimming, recreation, aesthetic enjoyment, etc.) under the Clean Water Act. These TMDLs typically establish strict pollutant load limits for municipalities, industries, and other sources such as agriculture. Problem TMDLs can be challenging and controversial, ...

Application of a risk management framework to a drinking water supply augmented by stormwater recharge
The Blue Lake is an important water resource for the city of Mount Gambier and the surrounding region, primarily as the drinking water supply source, but also as a tourist attraction. Mount Gambier’s stormwater is discharged directly via drainage wells into the unconfined, karstic Gambier Limestone aquifer, which in turn provides the majority of recharge to Blue Lake. Discharge of urban runoff to ...

With BOD, What You See is Often Not What You Get: The Difficulty with Accurate Testing for BOD in Industrial Stormwater Runoff.
Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an ...

Porous pavement technology - Case Study
Porous pavement systems address environmental issues, such as aesthetics and permeability, while providing needed support for a wide variety of loading requirements. From heavy emergency vehicles to pedestrian foot traffic, porous pavement applications range from fire access lanes to utility roads, trails, walkways, and other high use areas. Porous systems are designed to handle the most ...

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 ...
