Rehabilitation and Maintenance of Pump and Treat Systems

Presented:  January 31st, 2018

Synopsis: One of the common themes that emerged from the Phase 1 Portfolio Optimization Review of Navy’s IRP Sites is that the Navy has pump and treat system infrastructure that needs to be maintained and rehabilitated for continued protection of downgradient resources. Many sites have extraction and/or reinjection wells that were installed more than 15 years ago that will either need to be redeveloped or replaced in the future in order to maintain performance. These extraction and reinjection wells require significant investments and may result in high operating costs if not constructed or maintained effectively. This webinar provided an overview of key design aspects and maintenance practices needed to achieve optimal performance and to minimize life cycle costs for environmental remediation wells.

Portfolio Optimization (P-OPT) Review of the Navy's IRP sites - Phase 1 Overview and Findings

Presented:  August 23rd, 2017

Synopsis: This webinar reviewed the overview and findings from the Phase I Portfolio Optimization (P-Opt) review of IRP Sites. The presenters will first summarize the methodology and the 32 sites that were studied as part of the P-Opt Phase I effort. The presentation covered 5 primary common themes that emerged following the review. The first common theme involved the nature of primary receptors near the Navy's groundwater plumes. Contrary to the common assumption of drinking water being the primary receptor, surface water was actually the nearest and most common receptor at the 32 sites reviewed. Next, LNAPL management remains a challenging component of the Navy's IRP portfolio of sites. The application of emerging technologies like natural source zone depletion and the use of LNAPL transmissivity are required for the efficient management and closure of LNAPL sites. Emerging contaminants, including 1,4-Dioxane and PFASs, will be discussed and how the discovery of ECs at sites can impact long-term management of IRP sites. The role of matrix diffusion in the persistence of plumes and in limiting the effectiveness of cleanup technologies and approaches will also be discussed. Finally, the aging infrastructure of pump and treat systems will be discussed in relation to inadequate plume capture and long-term operation and maintenance requirements. The presenters will combine Navy field examples and lessons learned from the P-Opt Phase I to highlight some of the remaining challenges in the Navy's IRP. These broad findings will be used to refine and optimize the approaches at the Phase I sites and across the Navy's portfolio of IRP sites.

Dealing with Dilute Plumes

Presented:  April 5th, 2017

Dilute plumes are a challenge at many impacted groundwater sites because their outcome is often unclear.  There often is uncertainty about a dilute plume's source, uncertainty whether or not natural attenuation is working, and uncertainty about the effectiveness of any aggressive remedies planned.  This seminar discussed the roles of source depletion, matrix diffusion, and various natural and aggressive attenuating mechanisms in determining a suitable path forward for the plume.

Environmental Background Analysis Review and Case Study of Apra Harbor Sediments, Naval Base Guam

Presented September 30th, 2015

The presentation provided an overview of the Navy Background policy and NAVFAC guidance related to Environmental Background Analysis (EBA) for Sediment, EBA technical and scientific principles, and application of EBA to data collected for the Apra Harbor Sediment Remedial Investigation. The environmental data collected from the Apra Harbor sediment project provided an excellent example of metal background evaluation; Apra Harbor sediments will be used as a case study to demonstrate how multiple lines of evidence from both statistical and geochemical approaches are used to determine background concentrations based on Navy guidance. In this presentation, background evaluations such as spatial distribution, univariate plots, cumulative distribution plots, and geochemical association (regression analysis) will be discussed. The overall evaluation process used for Apra Harbor sediments follows Navy and EPA guidance, shows consistency between methods, and demonstrates the use of professional judgment. The importance of understanding the background concentrations of metals will be discussed as it relates to potential remedial footprints during remediation investigation recommendations and remedial alternative selection. Final environmental background concentrations (i.e., metals) will be calculated based on multiple (weighted) lines of evidence.

The Conceptual Site Model (CSM) – A Primary Focus of the Navy’s SAP Review

Presented July 23, 2014

 

The Sampling and Analysis Plan (SAP) and its review have traditionally focused on quality assurance (QA), sampling methods, analytical methods, etc. However, over the last 3 or 4 years, SAP reviews have increasingly focused on the site’s CSM and the data quality objectives (DQOs) of the planned effort, thus leading to improvements in the environmental stewardship that we exercise, early identification of future issues, and sometimes significant savings. This webinar presented information to assist RPMs in developing CSMs for their sites.
