The Remediation Innovative Technology Seminar (RITS) is NAVFAC’s showcase for the latest Environmental Restoration (ER) technologies, methodologies, and guidance news. The seminar is developed for Department of the Navy (DON) Remedial Project Managers (RPMs) to share the latest innovations and best practices. Others eligible to attend include Department of Defense (DoD) personnel, federal/state/local regulators, and contractors with an active DON ER contract. DON personnel will be offered priority registration and others are welcome to attend based on availability. For information on previous RITS offerings and materials please email EXWC.T2@us.navy.mil to inquire.

Non-Navy personnel will have opportunity to attend based on availability. For more information on topics or registration, please contact EXWC.T2@us.navy.mil.
Vapor Intrusion
Comparison of Vapor Intrusion Screening and Mitigation Technologies (2023) This presentation will discuss results of a detailed, in-depth review of the performance of various real-time indoor air gas analyzers for pre-screening volatile organic compounds (VOCs) and efficacy of multiple vapor intrusion (VI) mitigation technologies, when VI risks are identified. Project includes review of various real-time gas analyzers compared to HAPSITE®, results from evaluation of different heating, ventilation, and air conditioning (HVAC) filters to address VI emergency response, and an assessment of commercially available tools to address VI from sewer utilities. This lecture will provide lessons learned from these studies and how they can be applied to the greater Navy ERN/BRAC program.
Munitions Response
Innovations in Munitions Response Investigations (2023) This presentation will focus on innovations to address Munitions Response (MR) and Advanced Geophysical Classification (AGC) project challenges and solutions. One specific case study will cover the use of Simultaneous Localization and Mapping (SLAM) position technology, a high accuracy positioning system for use with MR technologies in GPS-denied areas, where MR investigation and remediation are limited to lower quality and less efficient methods. Other content will cover quality requirements for MR services, one-pass AGC methods, and underwater MR strategies and technologies.
Risk Management, Metals
Best Practices and Risk Management Options for Metal-Impacted Sites (2023) Metal-impacted sites are associated with industrial processes, former small arms firing ranges (SAFRs), waste disposal, and pesticide applications. They are commonly co-occurring with other contaminants such as petroleum hydrocarbons or chlorinated solvents, which are the primary drivers for risk (NAVFAC 2022). Metals may also be detected at concentrations that exceed risk-based screening criteria in soil and groundwater. This presentation will provide an overview of metals chemistry and mobility in environmental media for Remedial Project Managers (RPMs) to draw upon during site investigations, risk assessments, and/or the scoping process for remedial actions that target metals in soil and groundwater. This presentation will also provide best practices for developing and refining an optimized conceptual site model, important considerations for metals in background, information on how transport of metals can be influenced by biological, chemical, and physical processes, and considerations for improving risk to receptor estimations. An overview on challenges and solutions for SAFR and groundwater sites that includes case studies will be presented to provide best practices during site investigations.
PFAS
Best Practices for PFAS Sampling and Data Interpretation (2023) This presentation will provide the most appropriate procedures that should be followed when sampling for Per- and Polyfluoroalkyl Substances (PFAS) in different matrices. The matrices will include drinking water, groundwater, soil, sediment, surface water and tissue. The topic will include information on collecting control samples and which materials to use to ensure PFAS sampling integrity. Additional considerations for proper data analysis during the development of Site Investigation and Remedial Investigation reports will also be presented. This topic will also cover PFAS guidance updates from DOD and ASN.
Sediments
Using Surface-Area Weighted Average Concentrations (SWACs) to Optimize Sediment and Soil Remedies (2023) Planning and monitoring remedies for contaminated sediment and soil sites typically requires comparing contaminant data collected over different temporal and spatial scales to remediation goals. SWACs can be used to estimate mean contaminant concentrations over a specified area. This presentation will highlight how SWACs can be developed and used to estimate exposure point concentrations, develop remediation target areas, and provide data for long-term monitoring. It will also review SWAC guidance and present several case studies.
Directional Drilling, Complex Sites
Horizontal Directional Drilling and Horizontal Wells to Enhance Remediation at Complex Sites (2023) Recent advancements in design and emplacement technologies have reduced the up-front cost and time to install horizontal wells, resulting in a viable option for more cleanup sites. With that, implementation of horizontal wells has increased in recent years due to the ongoing challenges of difficult cleanups, such as under-building treatment or subsurface amendment distribution. The Navy has installed horizontal wells at several ER and BRAC sites to remediate petroleum hydrocarbons, chlorinated solvents, metals, and other contaminants of concern (COCs) in conjunction with various treatment technologies, such as in situ chemical oxidation (ISCO), soil vapor extraction (SVE), and multi-phase extraction (MPE); to mitigate vapor intrusion beneath buildings. This presentation will provide an overview of best practices for installing and operating horizontal wells; highlight recent advances in design and emplacement methods; and provide case studies employing horizontal wells that highlight success stories and lessons learned.
