In Depth Explanations

Chattahoochee Riverkeeper Policy Director, Chris Manganiello, shares information on the impacts of data centers on water and water quality and potential mitigations.

Impacts on Water

Data Centers require water for two things:

  1. On site - to cool the equipment

  2. Off site - to generate power via coal and gas energy generation

A “closed loop” cooling system may require little on-site water, but it uses more energy. Where is the power to run the data center going to come from?

It is important communities ask about:

  1. Regardless of cooling system type: how much water will be consumed?

  2. What is the plan for emergencies (i.e. during a drought or natural disaster)?

  3. Wastewater. What is in it? How often will it be tested? Is the local water treatment facility equipped to handle the wastewater contents?

The video above features - Dr Anne Mellinger-Birdsong, Medical and Health Advisor, Mothers & Others for Clean Air, covering the impacts of poor air quality on human health.

Impacts on Air Quality

A recent study found that regular testing of on-site backup power generators creates the same public-health impacts as running a large gas-fired power plant. Poor air quality can lead to asthma, cancer, and other chronic illnesses.

Data Centers impact air quality mainly via on-site power generation. It is important communities understand and regulate the following about power generation:

  1. Is the power-generation backup only? Or will it be on-site and run 24 hours a day / 7 days a week?

  2. When will backup power generators be tested? (Testing times should be limited to weekdays and only occur once a month)

  3. What air quality standards will the generators have to abide by? (EPA Tier IV or better is recommended)
