Fate of sodium sulfide and sodium bisulfide in steam muffler effluent

Abstract

A Major unknown at present is the actual direction of groundwater flow in the Puna district. This presents a difficult problem for monitoring the effect of geothermal discharge on the basal groundwater system. At the present time, the only way to be certain of encountering a discharge plume would be to drill Monitoring wells that completely encircle the injection point. A possible Method of determining the direction of groundwater flow would be to inject a highly conductive solution (salt water) into the basal lens and perform either a Mis-a-la-Masse survey around the injection well or perform a time domain electromagnetic survey around the injection point.
