SWIFT is an innovative water treatment initiative in eastern Virginia designed to ensure a sustainable source of groundwater while addressing environmental challenges such as Chesapeake Bay restoration, sea level rise and saltwater intrusion. The multi-year initiative will take already highly treated wastewater (that would otherwise be discharged into the Elizabeth, James or York rivers) through additional advanced water treatment to produce drinking quality water. This SWIFT Water will then be treated to match the existing groundwater chemistry and added to the Potomac Aquifer, the primary source of groundwater throughout eastern Virginia. This tour will include a visit to the Hampton Roads Sanitation District’s Nansemond Treatment Plant and Research Center in Suffolk, Va where the advanced water treatment takes place, as well as a USGS borehole Extensometer deployment near the site, that measures the compaction (and any resulting land subsidence) and expansion of the aquifer.
