【 摘 要 】

This document is a compendium of results of the calendar year (CY) 2001 Monitoring Well Inspection and Maintenance Program at the US Department of Energy (DOE) Y-12 National Security Complex (Y-12). This report documents the Cy 2001 well inspection events and their subsequent well maintenance requests. Well inspections are performed in order to assess the condition of the monitoring well and any subsequent maintenance needs. Inspections help to ensure that the collection of groundwater samples, and/or hydrologic measurements, are representative of the subsurface and not an artifact of changing downhole conditions. Inspections and maintenance contribute to the effective longevity of each well. Currently, the Y-12 Groundwater Protection Program (GWPP) inspects wells on an annual or triennial basis depending on the status of the well as follows: (1) the well is under the GWPP annual water quality sampling program (active wells); (2) wells where hydrological monitoring (e.g., semi-annual water level measurements, long term water level monitoring, slug test, pumping test, dye tracer test, etc.) is in progress (active or inactive wells); or (3) wells that are not in service (inactive wells), but are not currently scheduled for plugging and abandonment.
