  • Project profile - Newmont mining low sheep Well-Carlin, Nevada TS power plant-Battle Mtn., Nevada

    Background In 2005, AdEdge Technologies Inc. (AdEdge) was contacted to assist with design and implementation for two separate treatment systems related to the Newmont Mining site located in Carlin, Nevada, and an additional site in Battle Mountain. Site personnel and RTW Inc. evaluated arsenic treatment options, and eventually selected adsorption for these sites. At the Carlin, Nevada ...

  • 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 ...


  • 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 ...

  • Adsorption of fluoride from aqueous solution using low cost adsorbent

    High fluoride levels beyond the recommended value of 1.5 mg/L have been detected in several groundwater wells in Northern Ghana. This occurrence has led to the capping of many high yielding wells that hitherto have been major sources of drinking water for the populace in these arid areas. Most of the fluoride removal technologies applied in the area has not been versatile in effectively removing ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • Low-pH Ammonia Oxidation at a Biological Nutrient Removal Facility

    ABSTRACTMcAlpine Creek Wastewater Management Facility (MCWWMF), owned and operated by Charlotte Mecklenburg Utilities (CMU) of Charlotte, North Carolina, is permitted to treat 64 million gallons per day (mgd). Along with MCWWMF, three CMU treatment plants discharge effluent into the Catawba River just upstream of the South Carolina border. CMU worked with North and South Carolina regulators ...

  • Overcoming the challenges of using a rainfall–runoff model to estimate the impacts of groundwater extraction on low flows in an ephemeral stream

    Simple modelling approaches such as a spatially lumped, rainfall–runoff model offer a number of advantages in the management of water resources including the relative ease with which groundwater and surface water accounts can be evaluated at the river-reach scale in data-poor areas. However, rainfall–runoff models are generally not well suited for use in ephemeral river systems ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Understanding the True Cost of Water

    Overcoming Barriers to Corporate Water Stewardship For companies pursuing corporate water stewardship strategies, a common barrier to action is the perceived low cost of water “at the tap.” Water reduction, reuse, and recycling projects often do not meet investment hurdle rates or compare positively to other investments. This also acts to limit community and watershed ...

  • Understanding the True Cost of Water - Overcoming Barriers to Corporate Water Stewardship

    For companies pursuing corporate water stewardship strategies, a common barrier to action is the perceived low cost of water “at the tap.” Water reduction, reuse, and recycling projects often do not meet investment hurdle rates or compare positively to other investments. This also acts to limit community and watershed engagement actions outside of the fence line as well. Our water and ...

  • Shale gas extraction - frac water treatment

    The client The Client is a company which makes part of a Group based in the Eastern Europe and specialized in drilling activities and well services for the exploration/extraction industry. The Client’s needs Shale is a sedimentary rock that is predominantly comprised of consolidated clay-sized particles. Shale gas is produced from organic-rich shale ...

  • Soil and water: towards a larger-scale perspective of their relations

    Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...

  • Factors affecting formation of haloacetonitriles and haloketones during chlorination/monochloramination of Jinlan Reservoir water

    Formations of haloacetonitriles (HANs) and haloketones (HKs) from chlorination and chloramination from Jinlan Reservoir water under different treatment conditions were investigated in this study. Results showed that monochloramine rather than chlorine produced significant lower concentrations of HANs and HKs. In chlorination, the formation of HANs and HKs increased with the reaction time and ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Generation of Enriched, Anaerobic "Chase Water" to Repair Aquifer Biogeochemistry

    Understanding of the Problem “DCE Stall” is a problem frequently encountered when simple, “carbon-only” substrates such as hydrogen releasing compounds, emulsified oils, lactates or sugars are used to stimulate in situ reductive dehalogenation of chlorinated solvents. In response to the excessive accumulation of these problematic intermediates (e.g., ...


  • Visible-light-driven photocatalytic water splitting on nanostructured semiconducting materials

    In view of the unlimited resource of solar energy and the abundance of water on earth, producing hydrogen through photocatalytic splitting of water under solar irradiation has the great potential to offer a low cost, environmentally friendly green fuel that does not contribute to greenhouse gas emissions. Since the pioneering work of Fujisima and Honda in 1972, tremendous research on ...

  • Farmer Innovation: Improving Africa’s food security through land and water management

    The nature of agriculture is changing. Farmers across the world struggle to produce more food while facing changing rainfall patterns, a warmer world, and increased competition over land and water. Ecosystem degradation, declining soil fertility, and water stress add to these land use pressures. Nowhere are these challenges more severe than in sub-Saharan Africa’s drylands. Farmers in ...

  • San Joaquin Valley California - Arsenic removal from ground water

    Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High ...
