2000 to 2030 Urbanization/Suburbanization and Climate Change Timing of Spring Runoff in Maine Percent Change in Total Population 2000 to 2030 by Northern New England County USGS Fact Sheet FS 2005-3001
Urbanization/Suburbanization and Water Quantity • 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

Food 3.1 Fertilizer 1.8 Rain and dry deposition 10.5 Total N Output 2.4 kg N ha-1 yr-1 0.82 kg DIN ha-1 yr-1 (5 % of N Inputs)

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?

? ? Climate Change
Future Challenges in the Northeast • Impacts of climate change layered with suburbanization • Arsenic (interactions with other constituents) • Pharmaceuticals and Personal Care Products (PPCPs) • Groundwater water rights • Better interactions with society and policy makers
Challenges for the Appalachian States –WV, KY, TN • Large river systems - Ohio, Mississippi, Tennessee, Cumberland, and Kentucky • Coal-Fired Power Plants • - CO2 production, metal deposition, thermal effluents • Coal Mining • - acid mine drainage, sedimentation, metals • Transportation • - habitat alteration, dredging, invasive species Ohio River western WV Slide courtesy of Charles Somerville, WV
