  • Advances in Multilevel Well Technology

    Several detailed field studies performed at research sites in the 1980’s and 1990’s suggest that most contaminant plumes exhibit large variations in concentration over small vertical distances. These variations are caused by spatial variations in the contaminant source zones and heterogeneity of the geologic materials. Conventional monitoring wells have been shown to be ineffective for accurately ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • San Juan Island well production and tank level monitoring case study

    San Juan Island is a popular resort destination whose population fluctuates with the season and the arrival of Orca whales and salmon runs. To get to the island, you must first drive an hour north of Seattle to the city of Anacortes. From there you take a two-hour ferry ride through a 130 island group to arrive at the 20 mile San Juan Island, which is at the waterway entrance to Puget Sound. Bob ...

  • Latin America well-positioned for CDM

    The coastal desert of Colombia’s La Guajira state is a world away from Kyoto, the temperate Japanese city where representatives of 159 countries in 1997 signed the Kyoto Protocol on reducing greenhouses gases. The Caribbean laps against rickety settlements. Herds of goats range across scorching sands. Months, whole years, pass without rain. But Kyoto is well known to the inhabitants of La ...


  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis

    No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...
