• ERDC researchers use mobile trailers to expand critical messaging along inland waterways

    Low water, shoaling or missing buoys can cause hazardous conditions along our nation’s waterways, putting ships and crews at risk. Even the smallest disruptions in navigation can have catastrophic consequences for supply chains and the movement of essential goods across the country, impacting the economy. To help mitigate these hazards and strengthen gaps in broadcast coverage, researchers at the U.S. Army Engineer Research and Development Center (ERDC) are using deployable mobile trailers to ensure that critical messages can be transmitted to vessel traffic.
  • Groundbreaking ceremony for Rough River Dam Safety Modification project marks beginning of work on Phase 2

    The U.S. Army Corps of Engineers Louisville District joined local, state and federal officials July 21 to break ground on Phase 2 of the Rough River Dam Safety Modification project—a critical mega-project with an estimated total project cost of up to $891 million that will repair the high-risk dam and provide permanent flood risk reduction for downstream communities.
  • Corps of Engineers selects Hastings, Minnesota, resident for national award

  • Demonstration Validation of Air Supercritical Water Oxidation (AirSCWO 6) PFAS Destruction: Aqueous Film-Forming Foam Treatment by 374Water AirSCWO Technology

    Abstract: The Department of Defense (DoD) faces significant environmental challenges regarding the disposal of legacy aqueous film-forming foam (AFFF) containing persistent PFAS. This project, led by the US Army Engineer Re-search and Development Center (ERDC), evaluates the performance of the 374Water AirSCWO™ 6 system in destroying PFAS within AFFF. During the demonstration, 100 gal. of AFFF were treated, successfully meeting US EPA maximum contaminant levels (MCLs) for PFAS in the liquid effluent. The system achieved a destruction removal efficiency of 99.9993% for total PFAS as analyzed via the total oxidizable precursor (TOP) Assay (42 PFAS). Stack emissions remained below 500 g/h for vola-tile fluorinated compounds as measured by Other Test Method (OTM)–50. While the demister condensate exceeded US EPA PFAS MCLs, the total volume was negligible at less than 0.5 L. Energy efficiency analysis showed a consumption of 1.15 MWh per cubic meter of AFFF per order of magnitude of 42 PFAS destroyed and 12.9 kWh per gram of PFAS destroyed. Treatment costs varied and may range from $47 to $238 per gallon of AFFF. These results demonstrate the effectiveness of super-critical water oxidation technology for a safer disposal of legacy AFFF concentrates.

  • USACE dams reduced flood risk during December 2025 storms, helped prevent billions in potential damages

    During one of western Washington's most significant flood events in recent history in December 2025, U.S. Army Corps of Engineers flood risk management dams, water managers and emergency response operations helped reduce flood risk across the Puget Sound region by holding back peak flows, protecting communities, and helping prevent an estimated $8.7 billion in potential flood damages.

  • ACE-Mat: Medium- and Full-Scale Testing over Weak Soils

    Abstract: The US Army lacks the capability to rapidly repair and upgrade damaged roads along mobility corridors in contested, complex environments. Damaged low-volume roads are often encountered in military operational scenarios for transporting troops, supplies, equipment, and materials. Airfield matting is a unique solution for rapid construction of airfields in austere environments. The study presented in this report used medium-scale testing to evaluate the performance of the US Army Corps of Engineers’ ACE-Mat over varying soil strengths for rapid road repair scenarios. Tests were run using cyclic plate loading, simulating the load and tire pressure of a common bridge transporter military vehicle. Tests were completed on the mat and directly on the soil for comparison. An additional full-scale field test was completed to validate the medium-scale testing. The results of all tests indicate that the ACE-Mat provides exceptional performance improvement of weak soils.
