Abstract The site team has commissioned the USGS to conduct a study of aquifer properties and aquifer usage in the area. The study is titled Delaware City Potomac Aquifer Study and will include surveying water usage in the area, installing of additional monitoring wells, tracking water levels to see if the site is influenced by pumping from production wells, and perhaps redoing a pump test that had been previously conducted. An interagency agreement with the USGS is in place. The workplan and QAPP were completed during summer 2005, and water level instrumentation was also installed in Summer 2005. Water level measurements will begin in Fall 2005, and this phase of the study should be complete in Spring 2006. The budget is $150,000. New monitoring wells in the Potomac are not scoped as part of the study, but are expected to be a follow-up item to the study. The State would like to better understand shallow ground water flow before installing new Potomac monitoring wells to reduce the potential for creating preferential pathways between the Columbia and Potomac aquifers. Additional monitoring wells in the Potomac will likely be installed as a follow-up to the USGS study in Summer 2006.
