In the third episode of The WELL Labs Show, host Pavan Srinath is joined by Vivek Grewal (Technical Consulting, WELL Labs) to unpack the aquifers and groundwater in South India’s hard-rock landscapes.

The conversation explores why borewells keep getting deeper year after year, why wells dry up by January even after a good monsoon, and what it actually takes to address groundwater challenges in regions with hard rock.
