  • Integrated Constructed Wetlands: concept, design, site evaluation and performance

    'Integrated Constructed Wetlands' (ICW) are a joined-up approach to land and water management. Significant synergies were achieved by explicitly combining environmental, ecological and aesthetic objectives. Intercepted precipitation was found to be the main factor determining treatment efficacy. Soil infiltration and evapo-transpiration combined to enhance hydraulic residence time. A wetland area ...

  • Best management practices (BMPS) for discharging water from a construction site

    Having problems on your job site with regulations related to pumping water from your site? Discharge water may carry harmful compounds that can, and have affected our water quality and the ecosystem, hence the environmental agencies concerns. When pumping from dewatering systems, storm water management ponds (SWMPs), excavations or trenches, or any form of surface runoff, BMPs are needed to ...

  • Research on the process-based risk evaluation method of groundwater pollution for contaminated site

    A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a risk ...

  • Performance characterisation of a constructed Wetland

    Performance of a constructed wetland is commonly reported as being variable due to the site specific nature of influential factors. This paper discusses the outcomes from an in-depth study which characterised the treatment performance of a wetland based on the variation in the runoff regime. The study included a comprehensive field monitoring of a well-established constructed wetland in Gold ...

  • Pollutant removal in a multi-stage municipal wastewater treatment system comprised of constructed wetlands and a maturation pond, in a temperate climate

    A multi-stage municipal wastewater treatment system is proposed to comply with Mexican standards for discharge into receiving water bodies. The system is located in Santa Fe de la Laguna, Mexico, an area with a temperate climate. It was designed for 2,700 people equivalent (259.2 m3/d) and consists of a preliminary treatment, a septic tank as well as two modules operating in parallel, each ...

  • Air Pollution Control Specs

    As the full effect of the federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment.  With more than 25 years of proven success in a variety of industries, catalytic and thermal oxidation has become a popular method for controlling volatile organic compound (VOC) and hazardous air ...

  • Industry-Government-Pollution-EPA-Money

    Industry and Government have been hazardous polluters for decades. Negative Externality (the theory that those who make a decision do not have to pay the negative cost and effect of that decision) is a theory that could well apply to the consequence of previous hazardous pollution in the past.  An example of this is the answer I received after a presentation I gave on a non-thermal, EPA ...

  • Assessment of hydraulic containment of a landfill site

    Client: Waste Management Industry Location: Hydraulically contained landfill site, UK Services: Data review, hydrogeological risk assessment, hydraulic containment. Issues: Potential risk to groundwater and surface water, environment and human health. Leachate level control and trigger level compliance. ...

  • Modelling surface pollutant concentrations in the city of Zurich

    First results of a dispersion modelling study in the city of Zurich are presented. Surface pollutant concentrations (yearly averages) at several monitoring stations were modelled using the Danish OML-Multi operational model and compared with observations. For this purpose a detailed SO2 and NOx emission inventory for the year 1990 was constructed. The results show an average overestimation of the ...

  • Using On-Site Biological Methods to Clean Up Soil

    Decontamination companies and researchers in France are working to restore polluted soil using treatments that range from biological methods to soil washing and incineration. The problem of polluted soil was dramatically illustrated prior to construction of the Stade de France soccer stadium built for the 1998 World Cup. The location of the site, on industrial wasteland just north of Paris, ...

  • Time to address the air pollution control residue problem

    The incineration of municipal solid waste is gaining increasing importance in the UK, especially as the burning of waste can be used to generate energy, providing a more sustainable solution to our waste problem by diverting it from landfill sites. An issue with incineration is that some of our waste contains hazardous chemicals such as chlorine and lead which are volatilised during the process. ...

  • Wetlands for Industrial Wastewater Treatment at the Savannah River Site

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial research facility, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. Copper was the ...

  • Green remediation best management practices: site investigation

    Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination ...

  • Linking sanitation and wastewater treatment: From evaluation on the basis of effluent pollutant concentrations to evaluation on the basis of pollutant removal efficiencies

    In both developed and developing countries, centralised and on-site wastewater treatment systems have been developed for a long time. The main function of the wastewater treatment plants (WWTPs) should be removal of pollutants including organic carbon, nitrogen and phosphorus. Technologies applied to WWTPs are mostly with biological functions such as activated sludge, stabilization reservoir, ...

  • Analysis of trends in water quality: constructed wetlands in metropolitan Taipei

    Meandering through the most densely populated metropolitan areas of Taipei, Taiwan, the Danshui River and its tributaries have undergone the construction of 14 wetlands since 2004, as a means to improve water quality. This study was conducted to examine the functional capabilities associated with treating non-point source pollution through these riparian wetlands. Trend analysis was used to ...

  • Economic, environmental and socio-cultural sustainability of three constructed wetlands in Thailand

    Constructed wetlands (CWs) for wastewater treatment may be part of the answer to the urgent need for a change in the approach to wastewater treatment in developing countries. Although Thailand has several CWs, there have been no studies of their sustainability. To remedy this, the sustainability of three promising CWs in very different settings was assessed. These were located at Koh Phi Phi, a ...

  • Design, Construction, and Startup of Sustainable and Integrated Wetlands Treatment Process in Stockton, California

    ABSTRACTConstructed treatment wetlands have become an established technology for treatment of municipal and industrial wastewaters around the world. Wetland systems can provide treatment similar to conventional tertiary wastewater facilities if sufficient land is available but with lower energy and maintenance requirements. Ancillary benefits of treatment wetlands include wildlife habitat, ...

  • Even small sites must follow best practices to control erosion and runoff

    Since 1990, construction sites larger than 5 acres and municipal separate storm sewer systems (MS4s) serving populations over 100,000 have had to  abide by the rules of the Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Storm Water Program. This program was put in place to protect the country’s waterways from sedimentation buildup. ...
