See How YOU CAN MakE A Difference

Groundwater is one of our most precious resources, and it’s in jeopardy of being overused. DROP gives individuals, industries and farmers a practical way to reduce their groundwater footprint and protect the water supply by offsetting groundwater use with sustainable surface water. Each water share preserves 5,250 gallons of groundwater for the future – equal to an entire month of water usage by the average American household.

How it works


Most American municipalities rely on large quantities of groundwater for drinking, cooking and bathing every day, but we also need this underground supply to regulate natural water cycles on the surface. DROP uses a holistic strategy to create sustainable solutions to protect our groundwater reserve for future generations.
