  • High resolution multi-level monitoring for bedrock aquifers

    This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. Development of this DFN approach began at a sandstone site in California in 1997, where the initial version of a method for measuring ...

  • 5 Reasons to Test Your Well Water

    A lot of us know that we should test our water when we notice a problem with it. Three of the most common problems are when the water gives off a bad smell, is discolored or leaves behind stains. However do you realize that some problems you may be facing such as gastrointestinal upsets, dry skin, or even hardness may be a sign that there is something wrong with your water? Most dangerous ...

  • DOE regional partnership begins core sampling for large-volume sequestration test

    The Plains CO2 Reduction (PCOR) Partnership, one of seven members of the U.S. Department of Energy’s Regional Carbon Sequestration Partnerships program, has begun collecting core samples from a new characterization well near Spectra Energy’s Fort Nelson natural gas processing plant in British Columbia, Canada. Core sampling, along with a sophisticated well logging program that the partnership is ...

  • EPA releases results of Pavillion, Wyo. water well testing

    The U.S. Environmental Protection Agency (EPA) released the latest data from sampling conducted at Pavillion-area water wells yesterday at a public meeting at the Pavillion Recreation Center. Sample results indicate that the presence of petroleum hydrocarbons and other chemical compounds in groundwater represents a drinking water concern. The U.S. Department of Health and Human Services’ ...

  • Early tests don`t find tainted water from oil boom in the Northern Plains oil patch

    Random testing of shallow groundwater in the Northern Plains oil patch found no early evidence of contamination from an energy boom that's already seen more than 8,500 wells drilled, federal scientists said Monday. However, the U.S. Geological Survey cautioned that the tests could have missed contamination from surface spills or leaking well casings. That's because water can take many hundreds of ...

  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...

  • EPA Signs Two Clean Up Decisions in a Continued Effort to Protect Cape Cod Drinking Water
