The August 2022 issue of Water Well Journal focuses on drilling fluids and additives, a topic that is the subject of a Q&A as well as a column. The Water Well Journal Q&A begins on page 24 and is with Fred Rothauge, CWD, of Hydro Resources Inc. in Fort Lupton, Colorado. Rothauge, who was recently named The Groundwater Foundation's McEllhiney Lecturer in 2023, oversees drilling fluids well rehabilitation along with his responsibilities as the company's technical advisor. In the Q&A, Rothauge discusses supply chain issues in the water well industry impacting the selection and use of drilling fluids and additives, the importance of maintaining good fluids properties, steps that get missed the most often during mud testing procedures, and how drilling fluids impact a positive outcome when it comes to well rehabilitation. Rothauge also highlights misconceptions on purchasing drilling fluids, complex jobs he worked on, and what he will discuss in 2023 as the McEllhiney Lecturer.
