  • Drinking Water Resource Protection, Germany

    Reference Project: Drinking Water Resource Protection, Germany In the catchment area of a major drinking water supplier in western Germany increasing nitrate concentrations were noticed within a deep water-bearing layer. Although high nitrate concentrations, resulting from regional intensive application of fertilizers, were known from shallow layers in the area, they were new to the deep ...

  • Bottling water, greening farmers: the socio-technical and managerial construction of a 'dispositif' for underground water quality protection

    This paper proposes the description and analysis of the dynamics of an innovation process, which, over ten years ago, enabled a mineral water company to start protecting its underground water and to overcome a classical negative externality problem of no point-source nitrogen pollution. Based on methodological reflection and discussion of the dynamics of socio-technical arrangement in the ...

  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...

  • Reassessment of Cyanide Ambient Water Quality Criteria: An Integrated Approach to Protection of the Aquatic Environment

    ABSTRACTThe U.S. Environmental Protection Agency’s (USEPA) current ambient water quality criteria (AWQC) for cyanide were developed in 1984. Since this time, additional research on cyanide toxicity and analytical chemistry has suggested that cyanide AWQC values need to be updated to reflect the current state-of-the-science and to ensure that the methods for implementing the cyanide AWQC reflect ...

  • Critical Drivers for Wastewater Management in the Great Bay Estuary Watershed: Water Quality and Habitat Protection, and Sustainable Growth Management

    Increasing population growth resulting in substantial land development is contributing to increased wastewater generation and some increased nutrient loadings to Great Bay in New Hampshire. Seventeen wastewater treatment plants discharge to the Great Bay watershed. Some of the WWTP discharges do not meet current limits and others are not able to meet future limits, which are expected to include ...

  • Aquatic toxicity of acetonitrile and its water quality criteria for the protection of aquatic life in China

    The freshwater quality criteria of acetonitrile were studied on the basis of the features of the aquatic biota in China, and with reference to US EPA's guidelines. Acute tests were performed on 13 different species to determine 48h-EC50/96h-EC50 (or 96h-LC50) values for acetonitrile. 2ld survival-reproduction tests with Daphnia magna and ...
