  • 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 ...

  • Designing a constructed wetland for the detention of agricultural runoff for water quality improvement

    Received for publication December 18, 2008. The goal of this study was to construct a wetland that would detain runoff from a 162-ha watershed for the purposes of improving water quality. The volume of runoff that needed to be detained was determined to be that amount coming off the 162-ha watershed consisting of 146 ha of cultivated crop land and 16 ha of pasture that exceeded the amount that ...

  • Simple Separation: Diverting Wood And Cardboard at Construction Sites

    Diverting Wood And Cardboard At Construction Sites Residential home construction in Wisconsin generates 128,000 tons of residuals annually, according to a 1998 study by Camp, Dresser & McKee. Ten builders are participating in a project to demonstrate how easily major components of this waste stream can be recycled. The Metropolitan Builders Association (MBA) of Greater Milwaukee, the ...

  • 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 ...

  • Effects of highway construction on stream water quality and macroinvertebrate condition in a Mid-Atlantic Highlands watershed, USA

    Refining best management practices (BMPs) for future highway construction depends on a comprehensive understanding of environmental impacts from current construction methods. Based on a before-after-control impact (BACI) experimental design, long-term stream monitoring (1997–2006) was conducted at upstream (as control, n = 3) and downstream (as impact, n = 6) sites in the Lost River watershed of ...

  • 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 ...

  • On-site treatment of domestic wastewater using a small-scale horizontal subsurface flow constructed wetland

    A small-scale horizontal subsurface flow constructed wetland, located in North Greece, was designed and constructed to treat wastewater from a single-family residence. A three-year monitoring program was undertaken to evaluate the performance of this system. The monitoring campaigns were organized every 7 days. Water quality samples were collected at the inlet, at intermediate points (i.e. at the ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Assessment of the impact of traditional septic tank soakaway systems on water quality in Ireland

    One of the key threats to groundwater and surface water quality in Ireland is the impact of poorly designed, constructed or maintained on-site wastewater treatment systems. An extensive study was carried out to quantify the impact of existing sites on water quality. Six existing sites, consisting of a traditional septic tank and soakaway system, located in various ranges of subsoil ...

  • Comparative use of artificial neural networks for the quality assessment of the water reservoirs of Athens

    Neural networks are powerful tools that could explore the basic structure of environmental data. In this work, the most common artificial neural network (ANN) architectures, multi-layer perceptrons (MLPs), radial basis function (RBF) and Kohonen's self-organizing maps (SOM), are applied in order to assess the quality of the water reservoirs used for the domestic and industrial water ...

  • Characterizing potential water quality impacts from soils treated with dust suppressants

    Received for publication April 24, 2008. Two separate laboratory experiment series, surface runoff and steady-state seepage, were performed to determine if dust suppressant products can be applied to soils with an expected minimal to no negative impact on water quality. The experiments were designed to mimic arid field conditions and used two soils (clayey and sandy) and six different dust ...

  • Water Quality Risk Assessment for Dredging Operations, Plymouth Sound, UK

    ABSTRACTAs part of a formal Environmental Impact Assessment for a port development project in Plymouth Sound, UK, the potential risk of a deterioration in water quality from capital dredging was informed by the application of a probabilistic risk approach. In the absence of UK statutory sediment quality guidelines (SQGs) to assess acceptability of dredging operations, non-statutory guidelines are ...

  • Water Quality Benefits of Grass Swales in Managing Highway Runoff

    ABSTRACTGrass swales are a vegetated stormwater management technology that can remove surface runoff contamination through sedimentation, filtration by the grass blades, infiltration to the soil, and likely some biological processes. Two full-scale grass swales in the median of a four-lane highway were monitored during 18 storm events to characterize the overall performance of grass swales as a ...

  • Prevent hospital acquired infections during construction projects

    The issue of hospital acquired infections is a serious problem. According to several sources, three to four million hospital-acquired infections occur annually, with up to 80,000 fatalities. The costs of these infections are estimated to be between $4 billion and $5 billion per year (Air-Treatment Systems for Controlling Hospital acquired Infections, HPAC Engineering, April 2, 2008).Healthcare ...

  • Construction materials production. Application of the ABC-100 unit

    Expanded clay industry In the process of expanded clay production the argillous raw material homogenizes and mills in the drilling mud mixers and rollers. But these equipments not ensure qualitative desintegration. As result we obtain the expanded clay of low quality. Insufficiently desintegration and homogenizing of raw materials lead to the result when even 3% of carbonate ...
