3. New England is a water rich area and yet we still face issues with water supply In stream flow rules to protect aquatic and terrestrial biota and human use Example Issues…. Local cross basin transfers Global cross basin transfers – water bottling plants Unregulated private well withdrawals Artificial aquifer recharge Urbanization/Suburbanization and Water Quantity

9. Suburban Stormwater Management in Vermont How sensitive are streams to stormwater stressors? Are streams that are structurally impaired also functionally impaired? How can scientific knowledge be used to manage stormwater discharge to Vermont’s streams? How long will it take for streams recover from stormwater impairment?
