  • Drilling: Then & Now

    In a recent conversation with a colleague, we discussed the then and now of drilling. Reflecting back to 1988, it was jarring to realize that we have entry-level Geologists & Engineers today that were born that year! They won’t ever truly know what it was like then, and how far the drilling industry has come. They would be amazed at the lives, limbs, and hearing lost over past decades, ...

  • Installing Continuous Multi-Chamber Tubing Using Sonic Drilling

    As a geologist, core is the first thing that comes to mind when talking about sonic drilling— continuous, near complete core recovery through almost any lithology. Sand to silt transitions can be logged on a centimeter scale if desired. Geologic contacts can be mapped with accuracy of less than one foot. In an environmental ground water assessment, it seems an awful shame to collect (and pay for) ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...

  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...
