APTIM NAMED TOP 5 HAZARDOUS WASTE CONTRACTOR BY ENGINEERING NEWS-RECORD

The environmental consultant and leading developer of bioremediation of groundwater contaminants has landed in the top five of the same category for six consecutive years.

BATON ROUGE, La., July 14, 2025 /PRNewswire/ -- APTIM, an industry leader in environmental solutions and resilience, has again earned the distinction of ranking fifth in hazardous waste contractors by Engineering News-Record (ENR). This is APTIM's sixth consecutive year in the top five of the issue's hazardous waste category, which recognizes the firm's sustained excellence and leadership in environmental remediation, hazardous waste management, and nuclear decommissioning.

"This consistent recognition by ENR highlights APTIM's unwavering commitment to tackling complex environmental challenges through cutting-edge solutions and dedicated expertise," said APTIM Sr. Director of Environmental Remediation Tarek Ladaa. "Our teams are passionately focused on delivering projects that protect communities, restore environments, and set new standards for safety and sustainability."

Notable recent projects exemplifying APTIM's expertise include:

• PFAS Remediation: APTIM implemented innovative permeable adsorptive barriers, including a colloidal activated carbon barrier and an anion exchange resin funnel-and-gate system, at a Virginia site. The system, featuring two 60-foot funnel walls for expanded groundwater capture, effectively achieved significant reductions in PFAS concentrations through multiple sampling events, demonstrating robust and sustainable sequestration performance.
• Residential Remediation: In 2024, the firm successfully completed cleanup efforts at 296 residential properties in Indiana. The environmental remediation experts removed over 21,000 tons of lead-contaminated soil, restored community spaces, and significantly reduced environmental health risks for residents.
• Construction of Groundwater Treatment Plant: APTIM designed and constructed a 600-gallons-per-minute groundwater treatment plant in New Jersey, targeting thorium-232 and radium-226 contamination. The facility employs advanced treatment technologies—including green sand filtration for metals removal, carbon adsorption for volatile organic compounds removal, and ion-exchange adsorption for radiological contaminants—significantly enhancing environmental protection and community safety.

APTIM continues to invest in research and development, including advancements in PFAS treatment technologies, groundbreaking bioremediation applications, and sustainable approaches to nuclear waste management. The firm takes a proactive stance in addressing emerging environmental issues and meeting the evolving needs of its clients and communities.
