  • Research considerations for more effective groundwater monitoring

    Since numerous pathogens occur in feces, water is monitored for fecal contamination using indicator organisms rather than individual pathogens. Although this approach is supported by health effects data in recreational waters, it is questionable when used for drinking water. Most outbreaks in groundwater occur in systems that have not violated the US EPA's maximum contaminant limit (MCL) ...

  • Research on the evaluation method of groundwater quantity and pollution vulnerability

    Current research on groundwater vulnerability is aimed mainly at groundwater pollution vulnerability (GPV), and the vulnerability of groundwater quantity is seldom considered. It is important to carry out the groundwater vulnerability evaluation for the management of groundwater resources. This paper presents evaluation models and methods for assessing groundwater quantity and pollution ...

  • Research on the process-based risk evaluation method of groundwater pollution for contaminated site

    A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a risk ...

  • Researchers discover high uranium levels in south India groundwater

    The uranium isotopes during their course of their disintegration decay into other radioactive elements and eventually decay into stable lead isotopes. The cause of environmental concern is the emanation of beta and gamma radiation during disintegration. The present study tends to estimate uranium in groundwater trapped in granite and gneiss rocks. Besides, the study aims at estimating the ...

  • High groundwater site conditions

    Specific site conditions: BIOROCK non-electrical sewage treatment plants are unlike other wastewater treatment systems and are perfectly suitable for high groundwater conditions. BIOROCK plants can be installed in high water table or high groundwater sites by one of our trained installers. Our Research and Development team worked hard to find the best design to fit to difficult UK installation ...

  • Dressing down groundwater contamination

    Unlike the late Paul Newman, who bottled his special-recipe salad dressing and sold it in supermarkets, Dr. Robert Borden simply mixes up his own 'dressing' and pumps it into the ground. That’s because the environmental engineering professor and his graduate students are more interested in feeding microbes to clean up contaminated groundwater than in making just another Ranch dressing. “It’s ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

    Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for stormwater ...

  • Testing of concrete to determine the effects on groundwater

    The need for a more sustainable construction industry, as well as increasing pressures on landfill space, have led to an increasing use of recycled and secondary materials as aggregates in concrete1,2. However, if users are to have full confidence in these materials, it is important that they are shown to have neither an adverse impact on the properties of concrete, nor on the environment, ...

  • Groundwater: Low-flow Purging and Sampling

    Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost-benefit based methods Water has become a vitally important resource.  Maintaining its quality and quantity and avoiding pollution are set to be ...

  • Groundwater governance: explaining regulatory non-compliance

    This paper explores the non-compliance of water users through a case study of groundwater resources in the Gulf Islands (British Columbia (BC)) and the San Juan Islands (Washington). The research challenges two assumptions: that local regulations can easily incorporate scientific research, which in turn leads to sound on-the-ground management; that sound on-the-ground management translates into ...

  • Groundwater remediation using simulation-optimisation approach: A review

    Optimal design of a remediation system has been an active and important area of research since the past several years due to its potential to reduce the remediation cost substantially. The paper presents the state-of-the-art for application of simulation-optimisation approach to design an optimal groundwater remediation system. In the simulation-optimisation approach, the researchers have used ...

  • Slow arsenic poisoning of the contaminated groundwater users

    This paper gives impact of Arsenic contaminated water on human health as well as overview of the extent and severity of groundwater arsenic contamination in Bangladesh. Scalp hair is the most important part of the human body to monitor the accumulation of this type of poison. Therefore, an experiment has been carried out by Neutron Activation Analysis (NAA) at Atomic Energy Research Establishment ...

  • Remediating groundwater contaminated with chlorinated solvents - a Canadian perspective

    Chlorinated solvent contamination of groundwater is a recognized barrier to both potable water use and brownfield site redevelopment in Canada. Several high-profile trichloroethene (TCE) contaminant issues such as those in Cambridge, Ontario, and in Shannon, Québec, have increased public awareness of this problem, and also stimulated the Canadian consulting community to consider the use of in ...


  • Biological active groundwater filters: exploiting natural diversity

    In the Netherlands, biological trickling filters without chemical pre-oxidation are generally applied to treat anaerobic groundwater, containing methane, iron, ammonium and manganese. Previous research showed that all compounds can be removed in one filter step and that not only the ammonia oxidation (by nitrification), but also the iron oxidation is often a biological process, despite oxygen ...

  • Large Precipitation Events are Critical in Replenishing Groundwater Resources

    Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study by the U.S. Geological Survey and the Bureau of Reclamation. Groundwater is a vital source of water in the western United States, and will be increasingly ...

  • Natural and human-induced impacts on coastal groundwater

    Groundwater is the main source of potable water in most areas of Mazandaran province, like Sari and Babol city. Thus the safety of groundwater supplies is very important in these regions.  Unfortunately attention to groundwater quality has remained limited in Iran. In recent years, the growth of industry, technology, population, and water use has ...

  • How Reliable Are Your Groundwater Level Measurements

    Over the past few years, Eijkelkamp Soil & Water has gained extensive experience in the management of groundwater level measurement networks. This experience also serves as a foundation for our ongoing efforts to develop and enhance the collected data. For example, in the course of our activities, we have observed a growing discrepancy between manually-collected measurement data and ...

  • Impact of Groundwater Abstractions on River Flows (IGARF)

    This project was undertaken to review the current practice for the evaluation of groundwater abstractions on river and stream flows when assessing groundwater abstraction licence applications. This research contract formed Phase I of the National Groundwater and Contaminated Land Centre’s IGARF programme. The primary objectives of the project were to present a reasoned, robust and ...
