5. Seward Peninsula Water Resources
Vulnerability factors
Small watersheds
Loss of perched surface water with loss of permafrost
Low groundwater contribution
Low groundwater conductivity
Lack of treatment and storage infrastructure

6. Infrastructure impact
Increased use
Piped delivery
Increased storage
Increased resource
Ability to use lower quality water through treatment
