This book was released on 2005 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study determined the Well Head Protection Area (WHPA) for the community wells of Vermilion, Illinois, using a three-dimensional, numerical, groundwater flow model (MODFLOW and MODPATH). The flow model was calibrated to the regional topography. A sensitivity analysis yielded eight unique capture zones which were encompassed in a polygon to demarcate a composite WHPA for the Vermilion wells. Setting river bed conductivity to values greater than 1e-6 m1/s. (1) significantly impacted the shape and size of the capture zones; greater conductivity values yield smaller, less conservative capture zones; and (2) allowed river cells to move more than 10% of the total flow volume. Under these conditions, small, non-penetrating streams act as true hydrologic boundaries.* *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation). The CD requires the following system requirements: Microsoft Office.

This book was released on 1996 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: State Wellhead Protection Programs (WHPPs), utilize various methods to delineate the extent and configuration of those areas that contribute water to supply wells or wellfields. Once these Wellhead Protection Areas (WHPAs) are defined, state and local governments can implement zoning laws and land use regulations designed to protect these areas. These regulation may limit or prohibit activitities that may re-define zoning laws that could eliminate high risk activities from land areas that pose a threat to the water supply wells or wellfields. However, the methods used to delineate WHPAs, can, and often do, produce misleading results. These inaccuracies are due to either the method's inability to account for specific data in its calculation or the lack of sufficient hydrogeologic data to support more complex delineation methods. Data from a New Jersey site was evaluated using three different methods, relative differences were measured between the resultant 2-year wellhead protection areas for each method (i.e., Calculated Fixed Radius (CFR), Analytical Equations, and Numerical Modeling). The size differences in the resulting delineated 2-year WHPAs size ranged from 11% to 45% greater than and 16% to 68% less than the baseline 2-year WHPA.
