In this episode of H2O and Beyond, we head to Orange County California — home to one of the world’s most largest and most advanced water potable reuse systems called the Groundwater Replenishment System (GWRS). Join me as I explore how wastewater is transformed into clean, safe drinking water to be injected into their aquifers.

We'll break down the science of potable reuse, take a look at how Orange County has managed to address public perception, and hear firsthand from experts who are leading the charge in sustainable water innovation.
