The installation and development of groundwater monitoring wells is a primary element of the Y-12 Plant Groundwater Protection Program (GWPP), which monitors groundwater quality and hydrologic conditions at the Oak Ridge Y-12 Plant. This document is a groundwater monitoring well installation and development plan for the US Department of Energy (DOE) Y-12 Plant located in Oak Ridge, Tennessee. This plan formalizes well installation and construction methods, well development methods, and core drilling methods that are currently implemented at the Y-12 Plant under the auspices of the GWPP. Every three years, this plan will undergo a review, during which revisions necessitated by changes in regulatory requirements or GWPP objectives may be made.
Inspection and maintenance of groundwater monitoring wells is a primary element of the Oak Ridge Y-12 Plant Groundwater Protection Program (GWPP). This document is the revised groundwater monitoring well inspection and maintenance plan for the U.S. Department of Energy (DOE) Y-12 Plant in Oak Ridge, Tennessee. The plan provides a systematic program for: (1) inspecting the physical condition of monitoring wells at the Y-12 Plant and (2) identifying maintenance needs that will extend the life of each well and ensure that representative groundwater quality samples and hydrologic data are collected from the wells. Original documentation for the Y-12 Plant GWPP monitoring well inspection and maintenance program was provided in HSW, Inc. 1991a. The original revision of the plan specified that only a Monitoring Well Inspection/Maintenance Summary need be updated and reissued each year. Rapid growth of the monitoring well network and changing regulatory requirements have resulted in constant changes to the status of wells (active or inactive) listed on the Monitoring Well Inspection/Maintenance Summary. As a result, a new mechanism to track the status of monitoring wells has been developed and the plan revised to formalize the new business practices. These changes are detailed in Sections 2.4 and 2.5.
This document is the fourth revision of the Monitoring Well Inspection and Maintenance Plan for groundwater monitoring wells installed at the U.S. Department of Energy (DOE) Y-12 National Security Complex (Y-12) in Oak Ridge, Tennessee. This plan describes the systematic approach for: inspecting the physical condition of monitoring wells at Y-12, determining maintenance needs that extend the life of a well, and identifying those wells that no longer meet acceptable monitoring well design or well construction standards and require plugging and abandonment. This plan applies to groundwater monitoring wells installed at Y-12 and the related waste management facilities located within the three hydrogeologic regimes.
Plugging and abandonment (P & A) of defunct groundwater monitoring wells is a primary element of the Oak Ridge Y-12 Plant Groundwater Protection Program (GWPP) (AJA Technical Services, Inc. 1996). This document is the revised groundwater monitoring well P & A plan for the U.S. Department of Energy (DOE) Y-12 Plant located in Oak Ridge, Tennessee. This plan describes the systematic approach employed by Y-12 Plant GWPP to identify wells that require P & A, the technical methods employed to perform P & A activities, and administrative requirements. Original documentation for Y-12 Plant GWPP groundwater monitoring well P & A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P & A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P & A schedule be maintained. Wells are added to this list by issuance of both a P & A request and a P & A addendum to the schedule. The current Updated Subsurface Data Base includes a single mechanism to track the status of monitoring wells. In addition, rapid growth of the groundwater monitoring network and new regulatory requirements have resulted in constant changes to the status of wells. As a result, a streamlined mechanism to identify and track monitoring wells scheduled for P & A has been developed and the plan revised to formalize the new business practices.
This document is the monitoring optimization plan for groundwater monitoring wells associated with the U.S. Department of Energy (DOE) Y-12 National Security Complex (Y-12) in Oak Ridge, Tennessee (Figure 1). The plan describes the technical approach that will be implemented under the Y-12 Groundwater Protection Program (GWPP) to focus available resources on the monitoring wells at Y-12 which provide the most useful hydrologic and water-quality monitoring data. The technical approach is based on the GWPP status designation for each well (Section 2.0). Under this approach, wells granted ''active'' status are used by the GWPP for hydrologic monitoring and/or groundwater sampling (Section 3.0), whereas well granted ''inactive'' status are not used for either purpose. The status designation also determines the frequency at which the GWPP will inspect applicable wells, the scope of these well inspections, and extent of any maintenance actions initiated by the GWPP (Section 4.0). Details regarding the ancillary activities associated with implementation of this plan (e.g., well inspection) are deferred to the referenced GWPP plans and procedures (Section 5.0). This plan applies to groundwater monitoring wells associated with Y-12 and related waste management facilities located within three hydrogeologic regimes (Figure 1): the Bear Creek Hydrogeologic Regime (Bear Creek Regime), the Upper East Fork Poplar Creek Hydrogeologic Regime (East Fork Regime), and the Chestnut Ridge Hydrogeologic Regime (Chestnut Ridge Regime). The Bear Creek Regime encompasses a section of Bear Creek Valley (BCV) immediately west of Y-12. The East Fork Regime encompasses most of the Y-12 process, operations, and support facilities in BCV and, for the purposes of this plan, includes a section of Union Valley east of the DOE Oak Ridge Reservation (ORR) boundary along Scarboro Road. The Chestnut Ridge Regime is directly south of Y-12 and encompasses a section of Chestnut Ridge that is bound to the west by a surface drainage feature (Dunaway Branch) and by Scarboro Road to the east. The GWPP maintains an extensive database of construction details and related information for the monitoring wells in each hydrogeologic regime (including wells that have been destroyed or intentionally plugged and abandoned); the most recent hardcopy version of the database was issued in February 2003 (BWXT Y-12, L.L.C. [BWXT] 2003). This plan does not apply to temporary piezometers or other specialized groundwater monitoring/sampling devices that have been or may be installed for research purposes, hydrologic tests, pilot studies, or short-term investigations. This plan will be reviewed and updated in accordance with the schedule required in the Y-12 GWPP Management Plan (BWXT 2001). Between scheduled updates of this plan, any substantial changes or modifications to the plan, including changes in the GWPP status designation for each monitoring well identified in the plan, will be described in addenda issued by the GWPP Manager (or authorized designee). Information included in the addenda will be incorporated into the plan during the next scheduled update.
This report summarizes the well installation, plugging and abandonment and redevelopment activities conducted during the federal fiscal year (FY) 1997 at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee. No new groundwater monitoring wells were installed during FY 1997. However, 13 temporary piezometers were installed around the Upper East Fork Poplar Creek (UEFPC) in the Y-12 Plant. An additional 36 temporary piezometers, also reported in this document, were installed in FY 1996 and, subsequently, assigned GW-series identification. A total of 21 monitoring wells at the Y-12 Plant were decommissioned in FY 1997. Three existing monitoring wells underwent redevelopment during FY 1997. All well installation and development (including redevelopment) was conducted following industry-standard methods and approved procedures in the Environmental Surveillance Procedures Quality Control Program (Energy Systems 1988), the {ital Resource Conservation and Recovery Act (RCRA) Groundwater Monitoring Technical Enforcement Guidance Document} (EPA 19?6), and {ital Guidelines for Installation of Monitoring Wells at the Y-12 Plant} (Geraghty & Miller 1985). All wells were plugged and abandoned in accordance with the Monitoring Well Plugging and Abandonment Plan for the U.S. Department of Energy, Y-12 Plant, Oak Ridge, Tennessee (HSW, Inc. 1991). Health and safety monitoring and field screening of drilling returns and development waters were conducted in accordance with approved Lockheed Martin Energy Systems, Inc. (Energy Systems) guidelines.
This report documents the well-construction activities at the Y-12 Plant in Oak Ridge, Tennessee during 1989 and 1990. The well- construction program consisted of installing seventy-five monitoring wells. Geologists from ERCE (formally the Engineering, Design and Geosciences Group) and Martin Marietta Energy Systems (Energy Systems), supervised and documented well-construction activities and monitored for health and safety concerns. Sixty-seven monitoring wells were installed under the supervision of an ERCE geologist from March 1989 to September 1990. Beginning in September 1990, Energy Systems supervised drilling activities for eight monitoring wells, the last of which was completed in December 1990. 9 refs., 3 figs., 2 tabs.
This report summarizes the well installation activities conducted during the federal fiscal year (FY) 1995 drilling program at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee (including activities that were performed in late FY 1994, but not included in the FY 1994 Well Installation Program Summary Report). Synopses of monitoring well construction/well development data, well location rationale, geological/hydrological observations, quality assurance/quality control methods, and health and safety monitoring are included. Three groundwater monitoring wells and two gas monitoring probes were installed during the FY 1995 drilling program. One of the groundwater monitoring wells was installed at Landfill VI, the other two in the Boneyard/Burnyard area. All of the groundwater monitoring wells were constructed with stainless steel screens and casings. The two gas monitoring probes were installed at the Centralized Sanitary Landfill II and were of polyvinyl chloride (PVC) screened construction. Eleven well rehabilitation/redevelopment efforts were undertaken during FY 1995 at the Y-12 Plant. All new monitoring wells and wells targeted for redevelopment were developed by either a 2.0-in. diameter swab rig or by hand bailing until nonspecific parameters (pH and specific conductance) attained steady-state levels. Turbidity levels were lowered, if required, to the extent practicable by continued development beyond a steady-state level of pH and conductance.
