Most people in Miami-Dade turn on their tap without thinking twice about where that water comes from. I wrote this piece because I think that needs to change. There is a team of hydrogeologists at Miami-Dade WASD doing some of the most consequential environmental science in South Florida — monitoring saltwater intrusion, protecting the Biscayne Aquifer, and building the scientific foundation for decisions that will affect 2.8 million people for decades. They do it quietly, rigorously, and almost entirely out of public view. I have had the privilege of seeing their work up close — including the monthly PG Wednesday sessions led by Virginia Walsh, where specialists challenge each other's interpretations over real, high-stakes data. What happens in that room deserves a much wider audience. A special thank you to Rafael Carbonell and Christian Wensing, GIT, whose generosity and enthusiasm made this article possible. They are exactly the kind of professionals this field needs more of. I would love to hear your thoughts — whether you work in water resources, engineering, public policy, or care about where your drinking water comes from. Read it, share it, and tell me what you think. #WaterResources #Hydrogeology #MiamiDade #SouthFlorida #Groundwater #PublicHealth #ClimateResilience #WaterSecurity #WASD #BiscayneAquifer #FloridanAquifer #WaterInfrastructure #EnvironmentalScience #HBCEngineering
