THE UNDERGROUND

CaliforniaGeo is pleased to offer a series of online regular meetings we call The Underground  for registered participants.  Our productions will be offered using our Zoom platform, lasting approximately one hour, Noon-to-1pm Pacific Time.  The topic may be an issue, a technique, or a technology—or how certain policies and regulations may affect those.

We will feature a host and presenter, or a panel of two-to-three who will make a short presentation on the subject and then take live or chat-based questions from the audience.  These will be free for CaliforniaGeo professional and affiliate members, and $10 for others. Membership will be verified after registration before access is provided.  Participation is limited.

Terry will share examples of problematic GSHP installations ranging from easily resolved to catastrophic failures.  He’ll show how his focus on forensics helps reveal the best corrective actions
