Per- and Polyfluoroalkyl Substances (PFAS) in source area soil can create persistent groundwater plumes, which can be mitigated by soil removal or in situ treatment. Thermal desorption involves heating the soil to release PFAS chemicals, which are then removed using soil vapor extraction and treated aboveground. This process offers an onsite remediation alternative to offsite transport and treatment. This NAVFAC Fact Sheet on Thermal Desorption of PFAS from Soil summarizes two case studies from the Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP) demonstrating successful PFAS soil remediation using ex situ and in situ thermal treatment.

About us
The NAVFAC Technology Transfer (T2) Program supports information sharing to identify the Navy’s Environmental Restoration Program challenges and to promote the use of innovative and cost-effective solutions. The goal of the T2 Program is to communicate the latest information on research, technology innovations, and lessons learned from Navy case studies. Technical resources are shared on key topics through T2 e-mail updates, videos, fact sheets, handbooks, cost and performance reports, and more. The T2 Program also releases a monthly e-mail that provides links to newly released T2 products, policies, guidance, and training related to innovative technologies. OCT. 23, 2023: OUR CONTACT EMAIL HAS CHANGED. Our new email is EXWC.T2@us.navy.mil. Any questions you have regarding our Technology Transfer (T2) Program, including website, social media, newsletter, webinars, in-person seminars, or products, please contact us at EXWC.T2@us.navy.mil.

A NAVFAC Fact Sheet has been prepared on one-pass advanced geophysical classification (AGC) as a tool to support investigation, decision-making, and cleanup of munitions. Recent innovations have led to AGC sensors and software that allow classification in a single dynamic survey (often referred to as a “one-pass” survey). One-pass AGC can significantly reduce the costs of site characterization and cleanup as the number of excavations is reduced, and classification no longer requires two separate geophysical surveys.

Transitioning from active remediation to monitored natural attenuation (MNA) can be a cost-effective strategy for managing complex groundwater sites. This Fact Sheet outlines a technical approach for performing transition assessments using a new Transition Assessment Teaching Assistant (TA2) Tool, developed by the Department of Defense. The Tool helps to ensure the collection of key data to support a rigorous, site-specific transition assessment, while guiding informed site management decisions on if and when to transition to MNA.

Natural processes such as volatilization, dissolution, and biodegradation act in combination to reduce light non-aqueous phase liquid (LNAPL) mass over time. This fact sheet shares insights from several Department of the Navy (DON) installations where natural source zone depletion (NSZD) has been evaluated.

Remediation of chlorinated solvent plumes is a difficult technical challenge, as complete restoration of the groundwater back to original conditions has been demonstrated at only a few sites. This fact sheet summarizes a key factor responsible for this difficulty - matrix diffusion. Matrix diffusion is the process by which contaminants in groundwater initially migrate from areas of higher concentration in high-permeability zones (e.g., sands and gravels) into low-permeability media (e.g., clayey sands, silts, and clays).
