  • Time-Tested Advantages of Horizontal Wells

    Wells are wells are wells, right? Both conventional vertical wells and directionally drilled horizontal wells have a screened casing that is connected to solid riser casing which leads to the ground surface. Groundwater or soil vapor is drawn through a well screen to remove contaminants. Remediation agents such as air, bioamendmnents or potassium permanganate are injected through a well screen to ...

  • Evaluation of a Horizontal Well

    Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, ...

  • Case study - An air/ozone Sparge curtain to protect a municipal supply well

    Description Releases of petroleum contaminants from a retail gasoline station in a medium-sized California Central Valley town threatened a municipal supply well immediately adjacent and approximately 200 ft downgradient to the station. Methyl tert-butyl ether (MTBE) was present in groundwater concentrations up to 30,000 micrograms per liter (µg/L) and GRO up to 33,000 ...
