How Old Is Our Groundwater?

[tasnuba.swe]

Groundwater is possibly the most important freshwater resource on our planet, yet we know so little about it. We humans use—and often overuse—groundwater resources with little monitoring and oversight, and we also dump waste (from drilling or leaky landfills) into them. But groundwater goes unseen, so it’s difficult to calculate the quantity of available water—or its age.
To determine the age of the groundwater, the team used tritium data. Radioactive tritium was introduced to groundwater about a half-century ago due to thermonuclear testing.
