  • Monitoring fuels in Stormwater - Case study

    The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of ...

  • Model-based monitoring of stormwater runoff quality

    Monitoring of micropollutants (MP) in stormwater is essential to evaluate the impacts of stormwater on the receiving aquatic environment. The aim of this study was to investigate how different strategies for monitoring of stormwater quality (combining a model with field sampling) affect the information obtained about MP discharged from the monitored system. A dynamic stormwater quality model was ...

  • A Review on Stormwater Harvesting and Reuse

    Abstract - Australia is a country of some 7,700 million square kilometers with a population of about 22.6 million. At present water security is a major challenge for Australia. In some areas the use of water resources is approaching and in some parts it is exceeding the limits of sustainability. A focal point of proposed national water conservation programs is the recycling of both urban ...

  • Stormwater: Questions and Answers

    The whole subject of Stormwater is complicated. Here's a chance for you to check out some of the most frequently asked questions about stormwater . . . and their answers. What is an NPDES (National Pollutant Discharge Elimination System) permit? The Clean Water Act prohibits anybody from discharging 'pollutants' through a 'point source' into a 'water of the United States' unless they ...

  • Stormwater and lamella settlers: efficiency and reality

    ABSTRACTTwo settling devices treating rainwater from urban drainage areas and equipped with secondary sludge treatment were monitored over a period exceeding one year. The two devices differ in their design and in the quantity and quality of effluents received. Full analyses over approximately 30 mean samples of the intake and discharge effluents allowed judgment of the mean efficiency of ...

  • Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy

    This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

  • Stormwater and Spill Management at an Iron Pipe Foundry in Texas

    ABSTRACTLarge industrial sites have had permits for storm water discharges under the NPDES program of the Clean Water Act since the mid to late 80’s. Recent emphasis has been placed on regulated facilities to prepare and implement Spill Prevention, Control and Countermeasure (SPCC) plans under the Oil Pollution Prevention Act (40 CFR 112). A large iron pipe foundry in Texas has several storm ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • The impact of intentional stormwater infiltration on soil and groundwater

    ABSTRACTStormwater infiltration is a principle which is more and more utilized on urban sites in France. However, given the characteristics of urban surfaces, and notably the amounts of the different pollutants that stormwater is likely to contain, it is important to try to assess the impact of intentional stormwater infiltration systems on the soil, and on groundwater. To try to answer that ...

  • Calibration of stormwater quality regression models: a random process?

    Regression models are among the most frequently used models to estimate pollutants event mean concentrations (EMC) in wet weather discharges in urban catchments. Two main questions dealing with the calibration of EMC regression models are investigated: i) the sensitivity of models to the size and the content of data sets used for their calibration, ii) the change of modelling results when models ...

  • 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 ...

  • Specificity of a defined substrate method used to monitor balneability of tropical coastal waters impacted by polluted stormwater

    Defined substrate (DS) is an alternative technique to monitoring the water quality based on species-specific enzyme activity. Although more sensitive and more specific than traditional media, there is some controversy over use in the warmer waters of tropical and subtropical environments, rich in organic matter and microorganism groups capable of interfering with results. The aim of this study ...

  • Monitoring performance of a novel approach to channel design for environmentally- sensitive stormwater management: Lower Silver Creek, California

    Compound channel designs are increasingly being applied in urban watersheds to achieve both stormwater conveyance and ecosystem protection and restoration goals. A compound channel project was constructed on Lower Silver Creek in 2003, and a detailed monitoring program has been implemented to assess project performance and to improve future similar channel designs. Initial monitoring results ...

  • Controlling urban stormwater pollution by constructed wetlands: a Canadian perspective

    During the past 20 years, Constructed Stormwater Wetlands (CSWWs) have attained broad acceptance in Canada as effective measures for stormwater management. CSWWs are used mainly for improving stormwater quality by providing sufficient treatment volumes in shallow permanent pools. This leads to high requirements for land, which is one of the constraints on CSWWs use. Even though CSWWs perform less ...

  • Stormwater Management Program Long-Term Effectiveness Monitoring: Can I Reduce Sampling Frequency and Still Detect Trends to Determine BMP Effectiveness

     INTRODUCTION Stormwater program managers are challenged with meeting regulatory monitoring requirements to identify long-term trends and the effectiveness of the implementation of Best Management Practices (BMPs) and meeting multiple program requirements with finite resources. This paper provides stormwater managers with methods and several real-world scenarios using 10 years of data from ...

  • Characteristics of nutrient retention in a stormwater wetland during dry and wet days

    A 0.23-ha pilot wetland was constructed to examine its effectiveness for the control of nonpoint source pollution (NPS) from a 7.42-ha agricultural watershed in Korea. The wetland was operated during base flow and storm flow conditions and monitored for four years (2006–2009). The wetland was operated under high hydraulic loading rates (HLRs, 0.78 m/day on average) during rainy days. The average ...

  • Potential use of ionic species for identifying source land-uses of stormwater runoff

    Identifying critical land-uses or source areas is important to prioritize resources for cost-effective stormwater management. This study investigated the use of information on ionic composition as a fingerprint to identify the source land-use of stormwater runoff. We used 12 ionic species in stormwater runoff monitored for a total of 20 storm events at five sites with different land-use ...
