  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • Optimal groundwater contamination monitoring using pumping wells

    This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

  • Baseline groundwater quality in unconventional oil and gas fields

    In recent years, expansion of unconventional oil and gas production has prompted significant interest in potential impacts on drinking water resources. In many cases, water quality investigations rely on access to landowner water wells to develop baseline data prior to drilling; respond to spills, complaints, or incidents; or evaluate potential impacts due to drilling, completion, hydraulic ...

  • Case study - Multilevel sampling and monitoring, Maryland, USA

    Challenges Volatile Organic Compounds contaminated the groundwater posing a risk to nearby private water supply wells. The traditional approach of drilling and sampling multiple boreholes did not provide adequate data to characterize groundwater flow and contaminant migration in the complex fractured bedrock. Solution Westbay System* was installed ...


  • Arcane Groundwater problem plagues commercial district

    It was in 1995, when new storm water drains were being put in along the Beach street extension in Vineyard Haven, that Eric Anderson first learned of the serious contamination of the groundwater under his property. He and several other landholders in the area were required by state environmental authorities to begin an extensive program of sampling to find out the source of the pollution, with a ...

  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...
