摘要

This document is the triennial report for the Well Inspection and Maintenance Program of the Y- 12 Groundwater Protection Program (GWPP), at the U.S. Department of Energy (DOE) Y-12 National Security Complex (Y-12). This report formally documents well inspection events conducted on active and inactive wells at Y-12 during calendar years (CY) 2007 through 2009; it documents well maintenance and plugging and abandonment activities completed since the last triennial inspection event (CY 2006); and provides summary tables of well inspection events, well maintenance events, and well plugging and abandonment events during the reference time period. Well inspections are performed in order to assess the condition of monitoring wells and identify well maintenance needs. Well inspections help to ensure that the collection of groundwater samples and/or hydrologic measurements are representative of the subsurface environment and not an artifact of changing down-hole conditions. Timely well maintenance contributes to the longevity of each monitoring well. Effective stewardship, and a program of routine inspections, ensures that representative water-quality monitoring and hydrologic data are obtained from the well network (BWXT, 2006c).
