  • 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 ...

  • 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) ...

  • Researchers: Current global groundwater recharge models inaccurate

    A large-scale analysis of existing water resource models used around the world has found some key processes are missing, which means estimates of water availability could be wrong and cannot be reliably used for making water management decisions. The international team of scientists found that important climate change impact models are wrong in some areas. One finding was that groundwater ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Brackish groundwater desalination on the rise

    Brackish water is water that is more saline than fresh. It’s not quite as saline as seawater, but it’s still too salty to be used without treatment. Typically, advanced treatment technologies — reverse osmosis and ultrafiltration, as well as other membrane-based technologies — are needed to purify and desalinate brackish groundwater before its use. Brackish groundwater ...

  • 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, ...

  • Stevens Enhances Groundwater Remediation Effectiveness

    The Stevens HydraProbe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The ...

  • 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 ...

  • 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 ...


  • 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 ...

  • 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 ...
