  • A multi-method comparison of Atchafalaya basin surface water organic matter samples

    Received for publication January 29, 2008. Surface water organic matter (OM) was isolated from two distinct sites within the Atchafalaya Basin using a combination of XAD-8 and XAD-4 non-ionic macroporous resins and characterized by a suite of analytical methods, including elemental analysis, 13C cross polarization magic angle spinning nuclear magnetic resonance, attenuated total reflectance ...

    Economic Impact Of Recycling In Texas The Texas Commission on Environmental Quality (TCEQ) released its recent study on the economic impact of recycling activities in the state. Approximately 9.2 million tons of MSW designated materials were recycled in Texas in 2015. Typical recyclables (paper, plastics, metal, and glass), organics (yard trimmings, brush, green waste, and food and ...

  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • 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 ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Sensitive nanosilver-based spectrophotometric determination of Brilliant Blue FCF in surface water samples

    An accurate method was developed for the determination of Brilliant Blue FCF, a synthetic soluble colorant, in environmental samples. The method is based on the catalytic effect of silver nanoparticles (AgNPs) on the oxidation of Brilliant Blue FCF by hexacyanoferrate(III) in acetate–acetic acid medium at room temperature. Linearity of around four orders in the magnitude of concentration ...

  • Enteric viruses in surface water and sediment samples from the catchment area of Peri Lagoon, Santa Catarina State, Brazil

    This paper aims to quantify human adenovirus (HAdV), rotavirus species A (RVA), and hepatitis A virus (HAV) in surface water and sediments and to determine the viability of HAdV in these samples. Water and sediment samples were collected, and HAdV, RVA, and HAV were quantified by real-time polymerase chain reaction (PCR); HAdV was also evaluated for infectivity by a plaque assay (PA). For the ...

  • Assessment of heavy metal pollution in surface water

    A total of 96 surface water samples collected from river Ganga in West Bengal during 2004-05 was analyzed for pH, EC, Fe, Mn, Zn, Cu, Cd, Cr, Pb and Ni. The pH was found in the alkaline range (7.21-8.32), while conductance was obtained in the range of 0.225-0.615 mmhos/cm. Fe, Mn, Zn, Ni, Cr and Pb were detected in more than 92% of the samples in the range of 0.025-5.49, 0.025-2.72, 0.012-0.370, ...

  • A New Way to Locate Seeps Into Surface Waters

    How can we determine where groundwater is seeping into rivers and bays?  Knowing seep locations can help with selecting sampling locations, identifying contaminant sources, determining whether contamination is historic or on-going, and designing remediation.  Historically, methods for locating seeps have been limited.  Due to cost, sampling can only be done at a few ...

  • Influence of Copper Mine on Surface Water Quality

    Aras water basin is located in northwest of Iran. Sungun mine which is the largest open-cast copper mine of Iran is located in this region and is in the primary stages of extraction. The influence of mining activity on the quality of regional surface water has been taken in to consideration in this study. Accordingly, sampling was done from 5 local streams in the study area. In order to consider ...

  • Surface/bathing water monitoring (Denmark) - Case Study

    In order to find the possible fecal sources to the sporadic high concentrations of bacteria, the municipality of Hjørring (DK) has set up a BACTcontrol in the ditch to monitor the E.coli levels. For this purpose the BACTcontrol is built into a movable trailer and powered by solar panels. This allows the BACTcontrol to run continuously (6 samples per day) for 7-14 days depending on the ...

  • Inter-laboratory validation of automated SPME-GC/MS for determination of pesticides in surface and ground water samples: sensitive and green alternative to liquid–liquid extraction

    An automated solid-phase microextraction gas chromatography/mass spectometry (SPME-GC/MS) method was developed for the determination of semi-volatile pesticides from several classes with a wide range of polarities in an environmental matrix, and validated according to the rigorous standards of a large commercial laboratory reporting data requiring regulatory acceptance with the purpose of ...

  • In Situ Biological Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Surveillance of Influenza A and the pandemic influenza A (H1N1) 2009 in sewage and surface water in the Netherlands

    The role of the water cycle in spreading human pathogenic influenza viruses is poorly studied and is not considered to be significant. However, gastrointestinal symptoms developed in a large proportion of influenza A (H1N1) 2009 virus infected people during the pandemic in 2009 and fecal shedding was reported. This fecal route could potentially play a role in the entry of human pathogenic ...

  • Groundwater/surface water interactions along the Curtiss reach of the San Pedro River.

    A reach of the San Pedro River flows east of the Apache Powder Superfund Site and west of the Town of St. David in Cochise County, Arizona. As a result of the remedial investigations associated with the Superfund Site, this reach has been surveyed extensively since the mid-1980’s from approximately the Escalante Crossing to the Pomerene Diversion. In particular, the section downstream from ...

  • Reverse-phase HPLC method for the simultaneous analysis of triclosan and triclocarban in surface waters

    A validated reverse-phase HPLC-DAD for the simultaneous determination of triclosan and triclocarban in surface water has been developed, because this method has not been used for determination of these disinfectant agents so far. An isocratic elution was achieved using a Develosil RP Aqueous AR-5 RP-30 column with a flow rate of 1.0 mL min−1. The mobile phase consisted of mixed methanol and water ...

  • Evaluation of mutagenic activity of organic micropollutants present in surface waters

    Surface water to be employed in drinking water supplies can be characterised both by chemical analysis and mutagenic activity in order to detect genotoxic compounds present as environmental pollutants or produced by drinking water treatments. In our experimental conditions, only two samples out of seven raw and four processed water extracts (Amberlite XAD-2 concentration) gave mutagenic effects ...
