  • Surface Water Monitoring - Case Study

    Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • 3 Scientific Tools to Help You Better Understand Your Water Quality

    There are many ways of testing and understanding your water quality with online scientific tools and models. One such resource is the National Water-Quality Assessment (NAWQA) project run by the U.S. Geological Survey (USGS). The project, which was founded in 1991 to develop reliable information about water sources to support decisions on water quality management ...

  • LG Sonic to automatically predict algal blooms

    LG Sonic will make use of Artificial Intelligence (AI) to further develop the software algorithm which will make it possible to predict algal blooms based on water quality data automatically. Furthermore, it will provide detailed information about the intensity and the impact of the algal bloom on the ecosystem of the water body. The updated algorithm will be implemented in LG Sonic’s ...

  • Train derailment prompts contaminated land investigation - Case study

    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 ...

  • 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 ...

  • Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

    This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

  • Case study - Monitoring of pollution in the surface water in urban area

    Project reference Project: Pilot project in Umeå County Customer: Umeå County, Sweden Project period 2004 Nature of task: time integrated monitoring of PCBs, PAHs, OCPs, Toxicity and metals in three streams in Umeå city area. ...

  • Using PRTR database for the assessment of surface water risk and improvement of monitoring in Japan

    In April 2003, the first PRTR (Pollutant Release and Transfer Register) was published in Japan. It is shown how the PRTR can be used to improve environmental risk assessment with the objective of reducing risk to ecosystem integrity and human health. By examining the superposition of all chemical releases into rivers, high levels of several contaminants are uncovered. Most of these chemicals have ...

  • Comparison of Monitoring Approaches for Selected Priority Pollutants in Surface Water

    1 AbstractLaboratories from seven EU Member States under the coordination of the Joint Research Centre and in collaboration with the Provincia di Ferrara participated in a technical on-site project during which sampling and analytical methodologies for chemical monitoring according to proposed WFD provisions have been compared. Laboratories had been invited to take samples from a river according ...


  • 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 ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Feasibility assessment of surface water disinfection by ultrafiltration

    Ultrafiltration (UF) has been presented as an alternative to chemical disinfection to obtain safe drinking water, for its ability to remove microbiological contamination. Hollow-fiber UF membranes are designed as an effective barrier to microorganisms, for their high manufacturing integrity and for the ‘potting’ method adopted to seal fibers to the feeding/extraction manifold. ...

  • Surface water Sulfate dynamics in the northern Florida everglades

    Received for publication August 24, 2007. Sulfate contamination has been identified as a serious environmental issue in the Everglades ecosystem. However, it has received less attention compared to P enrichment. Sulfate enters the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of ...

  • Hydraulic “Fracking”: Are surface water impacts an ecological concern?

    Use of high‐volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural ...

  • Remote Monitoring of Ground Water and Surface Water as Part of the IWRM-Project Dong Nai River Basin, Vietnam

    The planned research project IWRM Vietnam, Dong Nai River Basin Phase II is a joint venture project, in which multiple partners from Germany, all in cooperation with partners in Vietnam elaborate the subject IWRM in the project area of the Dong Nai River Basin in Vietnam in its various aspects. The Dong Nai River Basin is located in the south of Vietnam and is, with an area of 35,000 km2, one of ...

  • Removal of aluminium and iron from surface water by conventional water treatment

    Detailed source water monitoring showed large variations in the total concentrations of aluminium and iron in the Vaal Dam, South Africa, which were highlighted as a specific concern for one of the largest drinking water treatment plants in South Africa. This study aimed to better understand the presence of these metals in the source water, removal of these metals through the conventional ...

  • Ex Situ Physical/chemical Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the ground water. Ex situ treatment, however, requires pumping of ground water, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • Monitoring surface water chemistry near magnesium chloride dust suppressant treated roads in Colorado
