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)

Contaminant hot spot evaluation
NGST technology setups two well electrodes or ground electrodes outside the contaminated area. Then we inject the current into the aquifer and flow through the contaminated area. Magnetic signals are collected by a sensor on the ground. The distribution of magnetic intensity is completed after counting and analyzing these magnetic data. Finally, the hot spots can be evaluated according to the magnetic abnormality.
As of 2020, Elisha Co. has completed 59 cases about LNAPL and DNAPL hot spots evaluation.
