Abstract
A water well rehabilitation system is provided for a water well having an open borehole through an aquifer substrate which extends to the bottom of the water well. The system includes an acid injection assembly having a concentrated acid supply, a water supply, and an eductor to mix the concentrated acid with water to form an acid solution to inject into one or more predetermined elevations in the open borehole. An acid injection control assembly includes a concentrated acid control valve and a water supply control valve cooperatively operative to maintain a predetermined acid concentration in the acid solution formed in and discharged from the eductor. A flush water assembly is disposed to inject an amount of flush water into the water well, and a well monitoring assembly monitors at least one operating parameter while a rehabilitation process is being performed in the water well.
