  • Natural Attenuation

    Introduction: Natural subsurface processes such as dilution, volatilization, biodegradation, adsorption, and chemical reactions with subsurface materials are allowed to reduce contaminant concentrations to acceptable levels. Natural attenuation is not a 'technology' per se, and there is significant debate among technical experts about its use at hazardous waste sites. Consideration of this ...

  • Sydney´s Sustainable House

    Introduction Sustainability or 'sustainable development' has become a term which is frequently applied to land use and social planning and resource issues. Sustainability is a concept which draws attention to development practices which can degrade natural ecosystems and deplete natural resources. If development is defined broadly to include any cultural activity, then sustainable development may ...


  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...

  • Exploring nature-based solutions - The role of green infrastructure in mitigating the impacts of weather- and climate change-related natural hazards

    Natural resource scarcity, climate change impacts, continued employment crises, public budget debts and economic recovery plans are some of the challenges that governments in Europe currently face. Moreover, Member States in the European Union (EU) need to continue building or rebuilding roads, sewage systems, levees, etc. (also known as grey infrastructure). Despite being essential for economic ...

  • Approximated EU GHG inventory: proxy GHG estimates for 2013

    Objective of the report This report provides estimates of greenhouse gas (GHG) emissions in the European Union (EU) and its Member States for the year 2013, covering the full GHG inventory (all sectors, except land use, land‑use change and forestry (LULUCF), and all gases). These estimates are also referred to as approximated ('proxy') estimates or inventories in this report as they ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
