A new advanced nuclear materials research facility under design and construction is a flagship initiative at a major international nuclear site. This state-of-the-art facility will house hot cells, radiation laboratories, and office space essential for advanced materials and fuels testing and examination.
Longenecker & Associates, a Geosyntec Company, recently conducted an independent review of the contractor assurance system (CAS) at a prominent national laboratory on behalf of the laboratory’s managing entity's board of directors. The review team comprised subject matter experts from our firm and national laboratory members.
A premier United States Department of Energy multidisciplinary science and engineering national laboratory engaged Longenecker & Associates, a Geosyntec Company, to conduct an independent review of its event management process. We reviewed the abnormal and unplanned events that are investigated, analyzed, and resolved, with an emphasis on integrating human performance improvement (HPI) principles across event response activities.
Longenecker & Associates, a Geosyntec Company, was engaged by national laboratory management to conduct an effectiveness review (ER) to assess the effectiveness, sustainability, and resilience of two corrective actions (Actions 1 and 2) from a recently implemented corrective action plan (CAP) developed following a series of low-oxygen alarm events at laboratory facilities.
A prominent national laboratory operating a critical pulsed-power research facility has been engaged in a multiyear effort to enhance the formality of its operations. This ongoing initiative aimed to reduce safety and operational incidents, continuously improve infrastructure, and increase the operational rigor to meet its mission of conducting complex experiments for governmental and other customers.
In support of the rapid expansion of American digital and energy infrastructure, an investor sought expert guidance before acquiring a combined cycle gas turbine power plant. Recognizing the complexity and significance of the transaction, the investor engaged Geosyntec to conduct a comprehensive technical due diligence review, focusing on environmental, health, and safety and sustainability risks.
Historical United States Navy operations resulted in trichloroethylene (TCE) impacts to soil and groundwater beneath a large military manufacturing building. The Navy turned to Geosyntec to quickly evaluate the vapor intrusion (VI) pathway in the occupied 23-acre building without interfering with mission-critical military manufacturing. Geosyntec later designed and installed systems to inhibit VI and to remove or destroy TCE contamination in soil and groundwater below the building. This project faced unique challenges associated with construction inside hallways, offices, and manufacturing spaces and navigated requirements of the unionized workforce.
Geosyntec supported the valuation of past and potential future environmental liabilities for a portfolio of historic sites including mines, ore processing operations, and related secondary manufacturing facilities.
An owner of a coal-fired power plant, committed to complying with the Federal Coal Combustion Residuals (CCR) Rule for its CCR storage impoundments, requested high resolution characterization (HRSC) and remediation of a release to groundwater adjacent to the impoundments.
A confidential utility client needed to evaluate potential performance impacts on a Class I deep injection well system that receives up to 500 gallons per minute (gpm) of inflows from various sources, including extracted groundwater containing coal combustion residuals (CCR) constituents and treated process water from the facility (e.g., flue gas desulfurization blowdown). Evaluating the level of treatment (e.g., design basis, mass removal requirements) to minimize impacts (e.g., scale formation) to the deep injection well and receiving limestone aquifer was also required.
