Workshop 4: Design and Construction Techniques for Recharge and Recovery Wells
October 28, 2007
This workshop will cover procedures for designing, installing, and managing recharge, recovery, and ASR wells. The presenters will describe case studies from several Arizona municipalities that use recharge and recovery technology to augment their water sources. Other topicsd will include methods of evaluating and rehabilitating existing wells. For more information about the course, click here.
Presenters
Marvin Glotfelty, R.G., is a Principal Hydrogeologist with Clear Creek Associates. He received his B.S. and M.S. from Northern Arizona University and is a Licensed Well Driller and Contractor (Type A-4) in Arizona. Over the past 23 years, he has investigated recharge, water supply, water rights, and groundwater quality problems. The technical Director of the Arizona Water Well Association for the past 17 years, Mr. Glotfelty has played a role designing, installing, rehabilitating, or abandoning over 600 water wells. Not only has he given over 50 presentations, but he has also authored over 20 publications, including Dictionary of Driller’s Terms (published by the National Ground Water Association in 2004). In 1995, he received the City of Phoenix Mayor's Environmental Award for his work with rehabilitation of municipal wells.
A hydrogeologist with the City of Scottsdale, Maurice Tatlow, R.G., has degrees from Northern Arizona University and Arizona State University. One of his main responsibilities is overseeing the City’s ASR program; he also helps operate and maintain about forty deep (150–180 foot) recharge wells in the vadose zone. Prior to joining the City, Mr. Tatlow worked as a hydrologist for 10 years with ADWR, where he helped to create and manage its land subsidence and aquifer storage monitoring programs. Before moving to Arizona in 1993, he worked 15 years in the oil industry, dealing primarily with borehole geophysical logging as an engineer, instructor, and training center manager for Atlas Wireline Services.
Gary Gin, R.G., a hydrologist for the City of Phoenix, has planned, designed, implemented, and managed various ASR projects. He has degrees from Sonoma State University and University of Nevada, Las Vegas. During his 11-year career, Mr. Gin has managed well siting, installation, and rehabilitation projects, as well as groundwater rights and ASR investigations. He has played a role in the permitting, siting, design, installation, testing, and rehabilitation of more than 70 water supply well while serving clients in private, municipal, and federal sectors. His current projects include an ASR wellfield that will not only improve groundwater production capacity but also add infrastructure redundancy in case of drought-related surface water shortages and treatment plant or transmission breakdowns.
