The Average Borehole Concentration (ABC) applet demonstrates the effects of sampling with a single long-screened well from a depth-varying concentration, located in depth varying hydraulic conductivity field. The applet demonstrates

  • The need for sampling at correct depths
  • Concentration averages with various screen lengths at different depths
  • Effect of hydraulic conductivity variation (check the Ignore Conductivity variation box)
