Major Aquifer
Study: Nebraska Sand Hills - northern High Plains
Objective:
The purpose of this study is to provide a broad-scale assessment of ground-water
quality in the Sand Hills deposits that overly the Ogallala Formation in
a large part of the northern High Plains region and to compare the ground-water
quality between these two hydrogeologic units.
Approach:
Randomly select and sample 40 domestic supply wells (see
map). The sampling density will be the same as the Ogallala Formation
Major Aquifer Study, one sample per 500 square miles. Each well will be
sampled once for a suite of chemical constituents.
Timing:
Report is in review.
Targeted Constituents:
Physical parameters, major ions, nutrients, trace elements, pesticides,
dissolved organic carbon, VOC's, tritium, and radon, bacteria, and coliphage
virus.
