  • Coupling Electrokinetics and Phytoremediation to Remove Uranium from Contaminated Soil: A Laboratory Pilot-Scale Study

    Abstract: Uranium is a naturally occurring trace element and radionuclide. Uranium is introduced to the environment anthropogenically because of industrial, military, and nuclear energy activities. The approach of coupled electrokinetic phytoremediation has been used to remove other heavy metals from contaminated soil. The objectives here are to investigate the distribution and solubility of uranium in soils with UO2, UO, and uranyl, and examine the processes of coupled electrokinetic phytoremediation in removing U from soils with perennial ryegrass at a laboratory pilot scale. A low-intensity direct electric current field was applied to the contaminated soil for 7 d at 8 h·d−1 after ryegrass was grown for 2 weeks, then, polarity reversal was employed for another 7 d at 8 h·d−1. The uranium redistribution took place among various solid-phase components due to changes in the pH and chemistry of the electrolyte solution. The electrokinetic field increased the U bioavailability in soils as water-soluble U and exchangeable U in contaminated soils with all U species. Thus, the EKF significantly increased the U uptake and bioaccumulation by ryegrass. The current laboratory pilot-scale test confirmed our previous observation from the pot greenhouse study–the coupled electrokinetic phytoremediation may have potential for application in remediating U-contaminated sites.

  • Mobile District Awards $4.5 Million Contract for Gautier, Mississippi’s Water Treatment Plant Expansion

    The U.S. Army Corps of Engineers, Mobile District, has awarded Southern Contracting, LLC of Biloxi, Mississippi, a $4.5 million construction contract to expand the City of Gautier’s Water Treatment Plant.

  • Mount Morris Dam Continues History of Flood Risk Prevention

    (MOUNT MORRIS, N.Y.) March 7, 2025 – The Mount Morris Dam, built and operated by the U.S. Army Corps of Engineers, Buffalo District, continues to serve as a critical safeguard against flooding in western New York, preventing an estimated $170 million in flood damages in 2024. Located on the Genesee River, at the northern end of Letchworth State Park and just south of Rochester, the dam plays a vital role in flood risk management for communities downstream, protecting over 160,000 residents in the Genesee River 100-Year Flood Plain and more than 200,000 in Rochester. By controlling water flow, the dam helps reduce the risk of severe flooding events that could cause extensive damage to homes, businesses and infrastructure.

  • ANNUAL TURKEY HUNT FOR PERSONS WITH DISABILITIES

    March 7, 2025 – The U.S. Army Corps of Engineers and the Paris Lions Club have scheduled the Annual Turkey Hunt for disabled persons, which will be held at Mark Twain Lake. The hunt will take place during the 2025 Missouri Spring Turkey season on Saturday, May 3, and Sunday, May 4, 2025, in the Indian Creek Recreation Area. The hunt will be restricted to permanently disabled (non-ambulatory, semi-ambulatory) individuals who have a valid 2025 Missouri spring turkey tag and a hunter safety certification card.

  • Effect of Fighter Aircraft Traffic on Full-Depth Reclamation with Thin Surface Layers

    Abstract: The US Army Engineer Research and Development Center (ERDC) constructed a full-scale test section to evaluate the effectiveness of different pavement surface technologies in sustaining fighter aircraft traffic. A deteriorated thin asphalt pavement was recycled utilizing full-depth reclamation (FDR) techniques with cement stabilization. Relatively thin surfacing solutions constructed with either conventional hot mix asphalt (HMA) or nontraditional surface materials were placed on the FDR layer and trafficked with a single-wheel F-15 load cart. Rutting behavior, instrumentation response, and nondestructive evaluation measurements were monitored during traffic. Experimental results showed that thin surface treatments and microsurfacing materials placed on FDR layers were capable of supporting an extremely limited number of F-15 operations, and the generation of foreign object debris (FOD) was a major concern. A 4 in. thick HMA layer was required to sustain a meaningful number of F-15 operations, that is, approximately 3,000, and a 2 in. thick HMA layer was required to sustain approximately 100 F-15 passes. An analysis using the Airfield Pavement Evaluation subroutine in PCASE suggested that existing stabilized equivalency factors were reasonable when the minimum asphalt layer thickness was specified. A reduced equivalency factor was observed when the asphalt layer thickness was less than the minimum thickness.
