  • Ask the Expert: Oil Analysis in Power Generation

    Uptime is one of the key considerations for all power generators. Electricity supply must equal demand at all times. Downtime, especially unplanned downtime, is very difficult to deal with and can be quite costly. Fortunately condition based monitoring can go a long way towards preventing unscheduled downtime and achieving ...

  • Volatile organic compounds in the nation’s ground water and drinking-water supply wells

    ABSTRACT Volatile organic compounds (VOCs) are produced in large volumes and are associated with a myriad of products, such as plastics, adhesives, paints, gasoline, fumigants, refrigerants, and drycleaning fluids. Widespread and long-term use of VOCs and their ability to persist and migrate in ground water raise questions about possible adverse effects on the environment, including ...

  • Estimating Future Impacts of Groundwater Contamination on Water Supply Wells

    In the following sections, we provide discussion and information to supplement the Feature Article. This material could not be included in the article itself due to space limitations of the printed ...

  • Self supply systems: Urban dug wells in Abeokuta, Nigeria

    Self supply systems are privately owned household water sources. The systems are generally perceived as playing a role in water service delivery to the rural poor. The systems' yielding safe drinking-water also receives little attention in literature and policy, relative to public and communal sources. This paper assessed urban self supply wells and argues that self supply is a coping water ...

  • Case study - An air/ozone Sparge curtain to protect a municipal supply well

    Description Releases of petroleum contaminants from a retail gasoline station in a medium-sized California Central Valley town threatened a municipal supply well immediately adjacent and approximately 200 ft downgradient to the station. Methyl tert-butyl ether (MTBE) was present in groundwater concentrations up to 30,000 micrograms per liter (µg/L) and GRO up to 33,000 ...

  • Case study - Ozone sparging closure of an industrial VOC spill site adjacent to a water supply well site

    Description An undocumented surface spill at an active manufacturing facility located adjacent to a public water supply well field released chlorinated volatile organic compounds (PCE, and its breakdown products: TCE, c-DCE, and VC) into soils and groundwater.  The driver for site cleanup was three water supply wells located 200 feet downgradient of the site bounds.  The chosen ...

  • An investigation on physical, chemical, and bacteriological quality of municipally supplied and well waters of the towns and city centre in the province of Nigde, Turkey

    Physical, chemical, and bacteriological properties of municipally supplied water and well water in selected towns and the city centre (Ni de, population 76,000) of the province of Ni de, located in central Anatolia, in Turkey, were investigated in this study. A composition of 70 samples were collected, 31 from Ni de city centre; 17 from Bor; 8 from Ulukı la; 6 from Altunhisar; 6 from  ...

  • The peak oil crisis and water supply

    Much is being made about the 'Peak Oil Crisis' in the media today. Gasoline and natural gas prices are high and continue to rise. But what is the 'peak oil crisis' and how does it impact our water supply?Peak Oil is discussed and defined in an excellent book by Kenneth S. Deffeyes entitled “Beyond Oil, The View from Hubbert's Peak”. As Mr. Deffeyes notes:'The supply of oil in the ground is not ...


  • Demand management in urban water supply

    Since the 1930s, the drinking water supply of the Rabat-Casablanca coastal area has depended on water transfers from groundwater, from Maamora, and surface water, from the Bou Regreg Basin. Assessments carried out during the 1980s, based on patterns of water use at that time, showed that by 2010, transfers ...

  • 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 ...

  • 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 ...

  • Abandon Well Contaminate Aquifer

    This article points out the magnitude of this urgent issue.  An abandoned well becomes an opening into an aquifer which is likely to introduce contamination.  Filling it in is a critical component of protecting the well water supply.  Click here to read the ...

  • Case study - Well monitoring for a water supplier

    The municipality company, in city of Luebek, Germany, provides potable water for approximately 120,000 households, all pumped from more than 30 wells.  These wells have water levels as deep as 160 meters.  The water levels of these groundwater wells must be measured with the highest possible accuracy.  Previously, the pressure probe's analogue output signals (4…20mA) that ...

  • Well oiled machines

    On November 1, 2004, Bridgewater's first oil skimmer began removing oil from its mill drains. At a cost of $6,500, the skimmer, supplied by Abanaki UK Ltd, represents a significant investment and underlies Bridgewater's commitment to enhancing the operation of its Effluent Treatment Plant. The acquisition of an oil skimmer materialized following lengthy periods of under performance from a ...

  • The Effects of Intermittent Supply on Water Distribution Networks

    The world’s population is increasing at a tremendous rate, the world’s renewable water resources are reducing rapidly, the gap between supply and demand is widening with urbanisation and climate change making it even wider. This paper reviews how the Water Board of Lemesos, Cyprus, a water utility with a proven history of managing extremely well its distribution network, was forced ...

  • Salting icy roads affects water supplies

    It’s basic chemistry: Saline water’s freezing point is much lower than fresh water’s, which can help keep ice from forming on roads. To reduce winter accidents, municipal and state workers often apply salt and other compounds to icy roads, because if not accidents start to happen and people end up in need cash in emergency. Unfortunately, this may have unintended consequences ...
