Long-Term Monitoring

Groundwater Monitoring Network Optimization Frontier Hard Chrome Superfund Site, Vancouver, Washington (2007)
This report reviews and provides recommendations for instituting a long-term groundwater monitoring network for Frontier Hard Chrome (FHC) Superfund Site in Vancouver, Washington. The FHC Site is a former chrome plating facility in the floodplain of the Colombia River. The current FHC groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). Recommendations are made for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring goals for the system. The primary goal of developing an optimized groundwater monitoring strategy at the FHC Site is to create a dataset that fully supports site management decisions while minimizing time and expense associated with collecting and interpreting data.

Long-Term Groundwater Monitoring Optimization, Clare Water Supply Superfund Site, StageRight Area, Clare, Michigan (2007)
This report contains a review of the long-term groundwater monitoring network for the StageRight (former Welltronics) Facility area near the Clare Public Water Supply, Clare Michigan. The current monitoring network was evaluated in September 2006 prior to activation of a new municipal well using a formal qualitative approach and statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The goal of the groundwater monitoring program is to track changes in concentrations of priority chlorinated constituents that may affect the drinking water remediation system used to treat the public water supply. The report includes recommendations for groundwater sample frequency and location based on current hydrogeologic, pumping, and contaminant conditions.

Long-Term Monitoring Network Optimization Evaluation for Operable Unit 2, Bunker Hill Mining and Metallurgical Complex Superfund Site, Idaho
(2006) (EPA 542-R-06-005)
This report presents a description and evaluation of the groundwater and surface water monitoring program associated with the Bunker Hill Mining and Metallurgical Complex Superfund Site (Bunker Hill) Operable Unit (OU) 2. A monitoring network consisting of 77 groundwater monitoring wells and 18 surface water stations was evaluated to assess its overall effectiveness at achieving the OU2-specific monitoring objectives, and to (1) identify potential opportunities to streamline monitoring activities while still maintaining an effective monitoring program, and (2) identify data gaps that may require the addition of additional monitoring points.

Long-Term Groundwater Monitoring Optimization, Newmark, Muscoy, and Source Operable Units, Newmark Superfund Site, San Bernardino, California (2007)
This report contains a review of the groundwater monitoring network for the Newmark, Muscoy, and Source operable units of the Newmark Superfund Site in San Bernardino, California. Affected groundwater at the Newmark Superfund Site covers an area of over 36 square miles and roughly 1,200 feet in depth with very few major geologic discontinuities. The current groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The report also contains recommendations for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring goals for the system.

Long-Term Groundwater Monitoring Optimization, Taylor Road Landfill Superfund Site, Seffner, Hillsborough County, Florida (2007)
This report contains a review of the groundwater monitoring network for the Taylor Road Landfill Superfund Site in Seffner, Hillsborough County, Florida. Leachate from the unlined Taylor Road Landfill has affected groundwater in an area with residential, agricultural and industrial land-uses including individual water-supply wells. The current groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The report also contains recommendations for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring goals for the system.

Navy and Marine Corps Optimization Work Group Website
The working group is comprised of representatives from the Navy's Engineering Field Divisions, Engineering Field Activities, the Naval Facilities Engineering Service Center (NFESC), the Naval Facilities Engineering Command (NAVFAC), and the Chief of Naval Operations (CNO). The goal is to develop guidance for optimizing Remedial Action Operation (RAO) and Long Term Monitoring (LTM) phases of site cleanup projects. The group is also tracking Navy lessons learned for obtaining cost-effective RAO and LTM contract services. This website contains:

• Navy LTM/Groundwater Monitoring Optimization Guidance
• Navy RAO Optimization Guidance
• LTM Optimization Case Studies
• RAO Optimization Case Studies

Roadmap to Long-Term Monitoring Optimization
The primary goals of this Roadmap are to assist site managers in: understanding the steps involved in conducting a long-term monitoring optimization (LTMO), determining whether a monitoring program could benefit from a LTMO assessment, identifying potential strategies for applying optimization techniques and evaluating which are appropriate for a program, and accessing more information and resources about LTMO tools, methods, and approaches. This roadmap focuses on optimization of established long-term monitoring programs for groundwater. Tools and techniques discussed concentrate on methods for optimizing the monitoring frequency and spatial (three-dimensional) distribution of wells (i.e., physical program optimization). The LTMO techniques discussed here can be described as qualitative or quantitative or some combination of these techniques.
