My name is Clifford Yantz and I’m very happy to be part of this wonderful Ministry. I have performed hydrogeologic investigations at over a 100 sites and specialize in the review and interpretation of hydrogeological data to determine groundwater flow characteristics and have designed or helped design over three dozen groundwater extraction systems. I have installed hundreds of wells and used groundwater flow models to evaluate hydrogeological resources and design groundwater extraction systems. I’m excited to go to Kenya again and drilling wells for W4LM.
