GRACast: Water Well Rehabilitation- Video Logging Techniques for Planning and Process Assessment


Presented by:

Christopher Johnson, PG Chg
Principal Hydrologist
Aegis Groundwater Consulting, LLC

 

INTRODUCTION:

Downhole video logging is an effective tool for assessing the before and after effects of well rehabilitation. Interpreting the efficacy of the rehabilitation can be more art than science, but there are means and methods for reducing the risks associated with such interpretation.  In this final installment of Video Log Interpretation, we'll look at before and after images and video, and present tools for selecting rehabilitation methodology and improved interpretation of the rehabilitation effort efficacy.

SPEAKER BIO:

Chris Johnson, President of Aegis Groundwater Consulting, LLC, has been a practicing professional geologist and hydrogeologist for 31 years.  Mr. Johnson has extensive experience in aquifer characterization, pumping tests, and in particular with well design, construction, maintenance and rehabilitation.  Additionally, Mr. Johnson has developed an expertise in addressing naturally occurring metals such as arsenic and uranium, specifically identifying the presence in the subsurface prior to well construction, and then designing wells that avoid these areas, resulting in water supplies of reduced metals concentrations in areas of significantly elevated groundwater concentrations.  Mr. Johnson is also a recognized expert in the field of well rehabilitation and well reconstruction and has published several articles on well rehabilitation for the National Groundwater Association’s “Water Well Journal”.
