Poeter E., J. McCray, G. Thyne, and R. Siegrist. 2005. Guidance for Evaluation of Potential Groundwater Mounding Associated with Cluster and High-Density Wastewater Soil Absorption Systems. Project No. WU-HT-02-45. Prepared for the National Decentralized Water Resources Capacity Development Project, Washington University, St. Louis, MO, by the International Groundwater Modeling Center, Colorado School of Mines, Golden, CO.

This report by Poeter et al. (2005) contains an error in the section on vadose-zone mounding. In the report, the figure and equations mistakenly use the full width (W) in place of the half-width, w, which should have been used. The vadose-zone layer examples in the report that demonstrate calculation and use of a maximum infiltration-area width, actually represent a maximum half width for a given Hmax. The methodology example in the report is still correct, however. The full width W was and should be used for design calculations. The terminology and equations for the saturated zone mounding in the report are not affected by this correction.
