The objective in this case was to determine average values of depth to groundwater for different combinations of landscape position, distance to surface water, and physiographic region. In such cases, a best estimate of depth was made based on similarity to other terrain unit combinations, depth values at nearby well locations, and prior knowledge about the area. After being developed, copies of the two map versions described above were sent to DEP regional office staff for their review and comments. In many respects, this newest version is a composite of the two earlier renditions. In some cases, values from version 1 were used, and in other cases the version 2 values were used.
Higher values indicate greater susceptibility.
