Outside-air (free) cooling for roughly 98% of operating hours, running essentially chiller-free. 1.58 MGD is the Phase 1 permitted cooling-water discharge cap (average discharge ~0.8 MGD). Full-campus water use is not publicly disclosed by AWS; residents have raised aquifer-withdrawal concerns.

Community sentiment
IDEM cited Amazon and its contractor for unauthorized wetland impacts and halted work in affected areas pending Section 401 water-quality recertification; a April 2025 public hearing drew 100+ residents opposing a pending wetland-fill permit near Bendix Woods County Park, with concerns over aquifer depletion and utility rates. Amazon separately committed a ~$143M community enhancement agreement to St. Joseph County.
