  • High quality bathing water protects human health

    The sewage treatment plant of Biarritz, France faced severe issues with inflowing water during heavy rain fall, resulting in untreated wastewater being diverted directly into the sea, alongside public beaches. A fast and reliable disinfection of the flow was needed. Kemira installed DesinFix disinfection technology which is designed for water reuse, and to handle such problematic flows ...

  • The Clog Blog

    Clogging and over pressuring are definitely problematic for Liquid Chromatography columns. Back in 2005 John Dolan’s sage advice to chromatographers to make an LC column last forever was simple, “Never open the box!” As John pointed out, this is not practical and I have to agree. But as an LC column manufacturer I have seen remarks from customers regarding clogging as though it ...

    This post is part of a series on World Water Week, an annual event designed to draw attention to and discuss global water issues. Read more posts in this series. Agricultural production often comes at the expense of water quality. As my colleague, Mindy Selman, ...

  • Water quality in the Arosa Bay

    Background One of the great impediments to further development of shellfish aquaculture in the north-west region of Spain isa perception that industry expansion and tourism could have negative environmental effects on the coastal waters. Especially the bay around Villagarcia de Arosa is very famous because of its excellent areas for shellfish farming. The government of Spain is ...

  • 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 ...

  • 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 ...

  • Water quality monitoring with hydrolab MS5

    Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river first disappears underground just outside the ...

  • Do water quality criteria based on non‐native species provide appropriate protection for native species

    The potential use of toxicity data for non‐native species to derive water quality criteria (WQC) is controversial, due to the fact that it is sometimes questioned whether criteria based on species from one geographical region provide appropriate protection for species in a different region. However, this is an important concept for the development of Chinese water quality criteria or ...

  • Derivation of Human Health‐Based Ambient Water Quality Criteria: A Consideration of Conservatism and Protectiveness Goals

    Under the terms of the Clean Water Act, criteria for the protection of human health [Human Health Ambient Water Quality Criteria (HHWQC)] are traditionally derived using United States Environmental Protection Agency (USEPA)‐recommended equations that include parameters for exposure assessment. To derive “adequately protective” HHWQC, USEPA proposes the use of default values for these ...

  • Streamside management zones effectiveness for protecting water quality after forestland application of biosolids

    Received for publication August 1, 2008. Biosolids, materials resulting from domestic sewage treatment, are surface applied to forest soils to increase phosphorus (P), nitrate, and ammonium availability. Retaining streamside management zones (SMZs) can limit nutrient pollution of streams. We delineated 15-m SMZs along three intermittent streams in an 18-yr-old Pinus taeda L. plantation. We ...

  • The economic value of basin protection to improve the quality and reliability of potable water supply: the case of Loja, Ecuador

    The objective of this study was to estimate the economic value that people living in Loja, Ecuador, place on the protection of two basins when the protection is designed to improve both the quality and reliability of the water supply for human consumption by urban residents. Empirical results indicate that households have an average willingness to pay (WTP) of $5.80 per month to preserve the ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • EPA Revises Water Quality Criteria

    Tens of thousands of members of the regulated community from industrial facilities with air emissions and wastewater discharges to municipal wastewater treatment plants, to hazardous waste site managers may be affected by changes to the WQC. US EPA Water Quality Criteria (WQC) which attempt to protect human health and the environment associated with the US waters, serve as the basis for most ...

  • 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 ...

  • 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 ...

  • 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 ...

  • European bathing water quality in 2010

    Europeans care about water quality and rank bathing water quality as a priority when judging their local environment. Knowing that they have clean and safe water to swim or play in is an important factor in their choice of a holiday or weekend destination. For the tourism industry, clean and safe water is also a major factor in attracting visitors to an area. To allow Europeans to make an ...
