  • The Geologist's License: How the FG and PG Exams Get Built — with Keith Rapp
    Apr 30 2026

    In this episode, we sat down with Keith Rapp, senior hydrogeologist, longtime volunteer with ASBOG (the Association of State Boards of Geology), and immediate past president of the organization. We dug into the professional geologist licensure process — what the FG (Fundamentals of Geology) and PG (Practice of Geology) exams actually test, how questions get written and vetted by panels of subject matter experts, why some states require licensure and others don't, and why Keith argues that licensure is fundamentally about protecting public health and safety.

    Keith walked us through his path from growing up in Duluth with a geomicrobiologist uncle, to a master's in hydrogeology at Baylor, to a career cleaning up contaminated sites using microbes — what he calls hydrogeomicrobiochemistry. We talked about his current work on PFAS bioremediation, the idea of "pushing evolution" by engineering biofilm environments where microbes can adapt to degrade forever chemicals, and the role of zeolites as remediation media.

    We also got into the practical stuff students and early-career geologists actually want to know: how to study for the FG exam, why test scores point you toward weak domains, what reciprocity between states looks like, the difference between an ASBOG license and an AIPG Certified Professional Geologist (CPG) designation, and why writing skills still matter in a hiring pile. We closed with a conversation about AI in geoscience — where it helps, where it gets you in trouble when your name is on a signed report, and how the profession should think about it going forward.

    If you're a student preparing for the FG, a working geologist thinking about getting licensed in another state, or just curious about how a professional credentialing system gets built and maintained, this one is for you. The ASBOG annual meeting is in Hershey, PA this October — open to anyone interested in the profession.
