Elisha said: Thus saith the LORD, I have healed these waters; there shall not be from thence any more death or barren land.
So the waters were healed unto this day. (2 Kings 2:21-22)
Hydrogeology
analysis
The hydrogeology of a real site is often heterogeneous. Therefore, the limited drilling often fails to present an accurate evaluation.
NGST method can carry out a high-density survey, and then count the difference by comparing it with the theoretical NGST distribution. Accordingly, the hydrogeology condition of the site can be obtained. NGST can help geological drilling to get more accurate soil distribution information.
Hydrogeology analysis is a newly developed method by Elisha. As of 2020, Elisha Co. has completed one case about hydrogeology analysis.
This figure shows the hydrogeological distribution obtained from 121 NGST survey points. The brown area indicates the zone with small magnetic intensity, and also represents the area with poor electrical conductivity. It is the area with sandy soil; the blue area is the zone with large magnetic intensity, and also the zone with clay soil.
This figure shows the hydrogeological distribution obtained from 7 Direct Push-EC measurements. The brown area indicates the zone with small electrical conductivity, which is the area with sandy soil; the blue area is the zone where the electrical conductivity is higher, and it is usually the zone with clay soil.
The hydrogeological distribution evaluated by NGST is similar to that obtained by Direct Push-EC. However, NGST evaluation according to much more data points can present more detailed distribution result.
