      How many times have you learned of a shallow groundwater
      contamination problem and heard someone say "We don't have to worry
      about the deep aquifer, it is protected by an overlying aquitard"?

      Join us in May for a 3-day CE Course on testing aquitard integrity:

      "Assessing Ground Water Movement and Contaminant Migration Through
      Aquitards: From Field Investigation to Hydrogeologic

      Join the Midwest GeoSciences Group and AEG NC Section for an
      intensive 3-Day Course dedicated to the practical aspects of
      hydrogeologic investigation of aquitards for environmental,
      engineering, and water resources projects.

      Location: Northern Illinois University Extension Campus, Naperville,
      Illinois, with a field component at Fermi National Accelerator
      Laboratory; May 8, 9, 10, 2007 (Tuesday – Thursday)

      CEUs by Northern Illinois University; 24 Contact Hours (2.4 CEUs)

      Aquitards (low-hydraulic conductivity hydrogeologic units) are
      critically important to groundwater and contaminant movement.
      Characterizing aquitards for environmental and water resource
      projects is important for protecting deep aquifers and understanding
      potential contaminant pathways for previously impacted aquifers.
      Both unconsolidated and bedrock aquitards share inherent low
      hydraulic conductivities, but approaches and field methods for
      characterizing each type can be completely different. Appropriate
      characterization requires site-specific understanding about the
      aquitard's origin, unit distribution, heterogeneity, fracturing, and
      the effects of secondary weathering or tectonics. Some of the course
      highlights include:

      •Learn to characterize ground water movement and contaminant
      migration through aquitards
      •Understand why aquitard characterization is critical to wellhead
      protection and the design of municipal water supply wells
      •Learn the hydraulics of aquitards, water table conditions, vertical
      seepage, confining behaviors, effects of discontinuities and much
      •Discover new techniques and field instrumentation for monitoring
      water quality and water levels in aquitards
      •Explore new approaches for ground water and solute transport
      modeling in aquitards
      •Observe water sampling and new slug test procedures in low
      hydraulic conductivity units
      •Discover the importance of differentiating a sequence of stacked
      low-hydraulic conductivity units for environmental and engineering
      •Participate in a comprehensive fracture analysis of multiple
      glacial till facies using an angle boring with continuous Rotasonic
      •Understand LNAPL and DNAPL transport through aquitards and the
      effects of secondary features
      •Learn about LNAPL behavior, distribution and recoverability within
      fine-grained sediments
      •Understand the potential for pathogenic virus contamination in deep
      aquifers thought to be protected by overlying aquitards

      This course also features up-to-date information and procedures on
      LNAPL behavior, distribution and recoverability in fine-grained
      sediments. We will also cover recent advances in pathogenic virus
      contamination discovered in deep aquifers where the procedures for
      identifying, sampling, sample transport and lab testing is
      continually being updated and improved.

      Apply this course to any aquitard setting. The course is located at
      Fermilab in Batavia, Illinois because of its conducive setting for
      testing aquitard integrity. The geologic framework at Fermilab
      consists of a stacked succession of clayey glacial units and
      underlying regional bedrock aquitard coupled with the extensive
      field instrumentation installed in each unit. Vertically nested
      wells and a single-borehole, multi-level monitoring system allow
      aquitard integrity testing and offer a side-by-side comparison of
      field methods appropriate to assess low-conductivity conditions. The
      glacial succession and the underlying sequence of Silurian-age
      dolomite and Ordovician Maquoketa Shale represent geologic
      conditions similar to those found throughout many other areas
      throughout the continental United States.
