Naval Facilities Engineering Command (NAVFAC) promotes collaboration and innovation by sharing information about the Department of the Navy (DON) Environmental Restoration Program (ERP) teams that have successfully implemented restoration projects nationwide. Recent success stories are presented below related to technology innovations and optimized strategies for managing sites.

Each year, individuals and ERP teams can be nominated for recognition of their outstanding efforts to protect human health and the environment by cleaning up Environmental Restoration (ER) sites in a timely, cost-efficient, and responsive manner. Restoring sites impacted by past defense practices ultimately protects military personnel and the public from potential environmental health and safety hazards. The annual Chief of Naval Operations (CNO) Environmental Awards is recognizes installations, individuals, and teams that demonstrate environmental excellence.

Success stories from across NAVFAC regions, along with recent award-winning projects are noted below:

Former Vieques Naval Installation, Vieques, Puerto Rico

Success_stories_vieques

Vieques Environmental Restoration Team (SECDEF 2018 Award Winner): Designed and implemented an innovative, time-critical removal action to safely and effectively clear underwater munitions and explosives of concern (MEC). Innovations included use of remotely-operated equipment to remove large bombs via a magnetic attachment, use of unmanned aerial vehicles, wide area assessment (WAA) with a towed magnetometer array to survey the densities and extent of underwater munitions, and field testing of passive samplers for munitions constituents in seawater.

Naval Base Coronado Environmental Restoration Team (CNO 2017 Award Winner): Evaluating vapor intrusion (VI) at 22 buildings in close proximity to shallow groundwater contamination due to volatile organic compounds (VOCs). Innovative VI investigation approaches were implemented including calculation of building-specific attenuation factors and use of sophisticated field instrumentation to provide real-time indoor air measurements versus sending air samples to a laboratory. VI mitigation measures included an optimized approach to sealing floor cracks and extraction of vapors from under an impacted building via a horizontal well. The extracted chemicals were converted to liquid and recycled to improve the sustainability of the project. For more information, visit here

Naval Base Point Loma, San Diego, California

Naval Base Point Loma Restoration Team (CNO 2016 Award Winner): Remedial action innovations included a soil vapor extraction (SVE) system with a horizontal well placed in a conveyance piping trench within the building footprint, an enhanced anaerobic bioremediation (EAB) system with a recirculation zone, and innovative VI investigation and mitigation measures for indoor air. As a result of the project, the indoor air quality was restored to meet levels that allowed the offices to be reoccupied. For more information, visit here.
