  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

  • Outbreak of acute gastroenteritis due to a washwater-contaminated water supply, Switzerland, 2008

    An operating error in a sewage treatment plant led to severe drinking water contamination in a well-defined district of a suburban municipality of Zurich, Switzerland. Despite the alert issued to the local population on the same day advising people not to consume the contaminated water, cases of acute gastroenteric diseases were subsequently observed. Considerable faecal contamination was ...

  • Quantitative analysis of microbial contamination in private drinking water supply systems

    Over one million households rely on private water supplies (e.g. well, spring, cistern) in the Commonwealth of Virginia, USA. The present study tested 538 private wells and springs in 20 Virginia counties for total coliforms (TCs) and Escherichia coli along with a suite of chemical contaminants. A logistic regression analysis was used to investigate potential correlations between TC ...

  • Mechanisms of post-supply contamination of drinking water in Bagamoyo, Tanzania

    Access to household water connections remains low in sub-Saharan Africa, representing a public health concern. Previous studies have shown water stored in the home to be more contaminated than water at the source; however, the mechanisms of post-supply contamination remain unclear. Using water quality measurements and structured observations of households in Bagamoyo, Tanzania, this study ...

  • Monitoring Metal Contamination in Water

    Metal contamination in drinking and source water has proven to have economic and health impacts on the human race. Regulatory agencies understand the importance of remediating metal contamination in our water supply to ensure safe consumption of drinking water. In order to properly remediate our water supplies, one must first determine cause of contamination and the source of the problem. ...

  • Pharmaceuticals and water supply

    Prescription Drugs have been detected in water supply systems of major cities in the United States including Europe, Canada, Australia and Asia.  In addition, quantities of antibiotics, steroids, antidepressants, and hormones are also present in the water supply (Doro-on, 2011).  These new emerging contaminants are designed with small concentrations that can generate specific health ...

  • Secondary removal of chlorophenolic contaminants in water

    In this study, several factors important for the design of a water supply treatment system for the removal of trace amounts of organic contaminants by microorganisms in a fixed-film were assessed. This entailed evaluating the effect of seeding with adapted microorganisms on the acclimation time, determining what depth of support material was required for removal of contaminants and observing the ...

  • Application of solar disinfection for treatment of contaminated public water supply in a developing country: field observations

    A sustainable and low-cost point-of-use household drinking water solar disinfection (SODIS) technology was successfully applied to treat microbiologically contaminated water. Field experiments were conducted to determine the efficiency of SODIS and evaluate the potential benefits and limitations of SODIS under local climatic conditions in Karachi, Pakistan. In order to enhance the efficiency of ...

  • Inequalities in microbial contamination of drinking water supplies in urban areas: the case of Lilongwe, Malawi

    Over past decades strategies for improving access to drinking water in cities of the Global South have mainly focused on increasing coverage, while water quality has often been overlooked. This paper focuses on drinking water quality in the centralized water supply network of Lilongwe, the capital of Malawi. It shows how microbial contamination of drinking water is unequally distributed to ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Design of dual water supply system using rainwater and groundwater at arsenic contaminated area in Vietnam

    Fresh water, a renewable but limited resource, is scarce in many areas of the developing world. This paper proposes a dual water supply consisting of both rainwater and groundwater to provide sustainable water for an arsenic contaminated area. In this paper, a novel model has been developed based on rainfall variance. A rainwater harvesting (RWH) system can obtain optimal performance by changing ...

  • Hand-pumps as reservoirs for microbial contamination of well water

    The retention and release of total coliforms and Escherichia coli was investigated in hand-pumps removed from tubewells tapping a faecally contaminated aquifer in Matlab, Bangladesh, and from a new hand-pump deliberately spiked with E. coli. All hand-pumps were connected to reservoirs of sterile water and flushed. Faecal coliforms were observed in the discharge from all three of ...

  • A look at some contaminants regulated in drinking water

    The U.S. Environmental Protection Agency regulates just over 90 contaminants in public drinking water systems. They include manmade chemicals as well as naturally occurring contaminants from rocks and soil. A look at some of the contaminants that fall under federal or state regulations: ARSENIC: Enters drinking water through eroding natural deposits in the ground or mining and other ...

  • A Forensic Approach to Solve a Ground Water Contamination Problem

    In 2000, a subdivision outside a small city in southeast Texas discovered that the water supply wells that individual households had drilled were contaminated with trichloroethylene or TCE as it is commonly called. Since the extent of TCE contamination seemed to extend for over a mile in length, it was thought the “event” or “events” leading to the contamination had occurred some years ago. The ...

  • Innovative Project for Hydrocarbons Contamination

    Baioni Crushing Plants, leader in the aggregate crushing sector has been operating for 40 years, have recently developed equipment and methods for environmental control. Several plants have already been supplied to third parties, now Baioni have full know-how of the technology and can ensure correct conception of the line based on the specifications of the soil to reclaim and can provide ...

  • Water supply and mining: the policy paradox in Ghana

    Ghana has been highly successful in mining for over a century. However, one area of concern is the negative impact of mining activities on water resources: their quality and quantity. Mining companies are guided by rules and regulations, particularly those that have to do with the quality of water supply. Safe water supply is essential for improved health and quality of life for increased ...
