  • Spatial pattern of arsenic contamination in shallow wells of Bangladesh: regional geology and nonlinear dynamics

    Since the discovery of large-scale arsenic contamination of groundwater in Bangladesh more than a decade ago, studies related to its spatial characterization have relied on geostatistical approaches and the classical notion of linear stochastic dynamics. This study explores an alternative nonlinear approach, with a motivation to possibly achieve more cost-effective solutions for Bangladesh. It ...

  • Mississauga Case Study (In Situ Gas Thermal Remediation (GTR™))

    In Situ Thermal Desorption in conjunction with soil vapor extraction was used to remove volatile organic compounds which contaminated the groundwater and saturated soil areas of a former metal fabricating facility in Ontario, Canada. The site had VOCs detected above the Canadian water standard in various monitoring well locations.  The remediation goal was achieved in 84 days and saw a 98% ...

  • North LA Case Study (C3 Technology)

    The project site is an industrial facility located in the foothills of northern Los Angeles, California. The facility utilized chlorinated solvents in operations. Based on soil borings, site geology consisted of unconsolidated gravely sands, sand, silty sand, sandy silt, and silt from ground surface to more than 200 feet below ground surface (bgs). Groundwater was encountered at the site at ...

  • Loveland Case Study (In SItu Gas Thermal Remediation (GTR™))

    The Loveland Sinclair gasoline station was selected for In-Situ Thermal Remediation (ISTR) using Gas Thermal Remediation (GTR) technologies. The GTR remediation system was designed to target a treatment area of approximately 14,000 square feet and includes a treatment volume of approximately 3,100 cubic yards. Vadose and saturated zone impacts, including a thin layer of light non-aqueous phase ...

  • Photochemical Transformation of Bisphenol A Promoted by Nitrate Ions

    Bisphenol A [2, 2-bis (4-dihydroxydiphenyl) propane] (BPA is widely used as a raw material for polycarbonate and epoxy resins. The residue level of BPA in surface water was shown to be at a rather high level, ranging from 4.4x10-10 to 5.3x10-8 mol L-1 by the U.S. Geologial Survey (Kolpin et al. 2002) and 5.7x10-9 to 5.7x10-5 mol L -1 in landfill leachates in Japan (Yamamoto et al. ...

  • Building analytical competence for geoscience students through use of Raman spectroscopy

    Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory. In geoscience professions, these tools are increasingly being supplemented by field and laboratory instrumentation that utilizes spectroscopy. The availability of newly-developed, lower-priced ...

  • Evaluation of groundwater potential zones using GIS and remote sensing in Noyyal Basin, Tamil Nadu, India

    Groundwater is a dynamic and replenishable natural resource but in hard rock terrain the availability of groundwater is of limited extent. The occurrence and movement of groundwater in an area is governed by several factors. It is therefore, necessary to integrate several factors on these terrain characteristics. This can be best achieved by geographical information system (GIS). River Noyyal ...

  • Community Structure of In-Stream Bryophytes in English and Welsh Rivers

    Information on the distribution of bryophytes in mainland British rivers was collected as part of the Joint Nature Conservancy Council (JNCC) survey of in-stream macrophyte distribution between 1978 and 1997. A sub-set of sites (1604) containing the 50 most common bryophytes was analysed. The commonest of these 50 species were Fontinalis antipyretica and Rhynchostegium riparioides. The majority ...

  • Natural background levels for chemicals in Icelandic aquifers

    Information about natural background levels (NBLs) of chemicals in source waters allows water utilities to identify trends in drinking water contamination. We estimate NBLs for chemicals in source waters for Icelandic water utilities at both national levels with all data pooled, and according to geological regime. NBLs were derived by collecting samples from 79 aquifers considered largely ...

  • Impact of catchment properties on aquatic chemistry in the rivers of Latvia

    The relationships between land use characteristics and aquatic chemistry (nutrient concentrations, major inorganic ions and indicators of organic matter concentrations) were analyzed to determine factors controlling the runoff of dissolved substances, spatial variability of water chemical composition and possible impacts of pollution sources in Latvia. Groups of factors were found to determine ...
