Presentation Transcript

  1. USGS Activities in Support of the MEP, Cape Cod • Delineated watersheds to fresh and coastal waters on Cape Cod: about 600 estuaries, ponds, streams, and wells: in cooperation with MADEP (completed 2004) • Developed and evaluated flow-based (particle-tracking) methods to estimate nitrogen loads: in cooperation with Cape Cod Commission (completed 2007) • Develop and evaluate solute-transport methods to predict nitrogen loads resulting from TMDL-driven wastewater management actions: in cooperation with MADEP (completed spring 2012)

  2. USGS Activities in Support of the MEP, Cape Cod • Delineated watersheds to fresh and coastal waters on Cape Cod: about 600 estuaries, ponds, streams, and wells: in cooperation with MADEP (completed 2004) • Developed and evaluated flow-based (particle-tracking) methods to estimate nitrogen loads: in cooperation with Cape Cod Commission (completed 2007) • Develop and evaluate solute-transport methods to predict nitrogen loads resulting from TMDL-driven wastewater management actions: in cooperation with MADEP (completed spring 2012)

  3. Flow-Based Analyses Using Recharge Areas • Recharge areas delineated for estuaries, ponds, streams, and wells • Useful for estimating “instantaneous” loads under static hydrologic conditions Recharge Areas Travel Times

  4. Barnstable Harbor and Popponesset Bay Watersheds Surface-water Dominated: Popponesett Bay Ground-water Dominated: Barnstable Harbor

  7. Subregional Model of Popponesset Bay Watershed • Linked to regional model by specified heads • 480 rows, 256 columns, 27 layers • 100 ft uniform horizontal discretization • Flow simulated using MODFLOW-2005 • Transport capabilities using MT3D

  8. Incorporation of MEP Scenarios, Town of Mashpee • Onsite systems in unsewered parcels discharged at 26.25 mg/L • Nitrogen from onsite septic systems removed from proposed sewered areas • Accumulated septic-system return flow discharged at treatment plants • Nitrogen in treated water discharged at 3-10 mg/L
