"Data centers draining resources in water-stressed communities"
The water used in data centers is often treated with chemicals to prevent corrosion and bacterial growth, rendering it unsuitable for human consumption or agricultural use. This means not only are data centers consuming large quantities of drinking water, but they are also effectively removing it.
