  1. Restoring eelgrass to the Neponset River Estuary Watershed Characteristics October 15, 2012

  2. Outline • Watershed & sub-watershed area • Land use/Land Cover • Surficial Geology/Bedrock Lithology • Wastewater Infrastructure • Aquatic Habitat

  3. Watershed Definition • The area of land that drains into a body of water • “Communities connected by water” http://water.epa.gov/type/watersheds/whatis.cfm

  4. The watershed: • Boston • Canton • Dedham • Dover • Foxborough • Medfield • Milton • Norwood • Randolph • Quincy • Sharon • Stoughton • Walpole • Westwood 130 sq. miles

  14. Recommendations • Continued monitoring of land use changes over time to understand and predict ecological consequences incurred by sensitive habitats • Investigate the relationship between bedrock lithology, surficial geology, and groundwater features • Survey wastewater infrastructure of municipals in the watershed and assess the overall status of these systems • Investigate dry deposition processes affecting the Neponset River Watershed
