Haley & Aldrich, a national environmental and engineering consultancy, has acquired The ELM Group, an environmental and engineering consultancy based in Pennsylvania and New Jersey. Together, Haley & Aldrich and ELM will offer an expanded slate of services to address pressing environmental, sustainability, and resilience issues.

The acquisition will unite Haley & Aldrich’s nationwide geotechnical engineering and environmental expertise with ELM’s regional contaminated site, sediments, and natural resource practices. This combination strengthens both companies’ capacity to serve industrial, manufacturing, and other clients in the mid-Atlantic region, where there is a high demand for services related to environmental compliance, legacy contamination, and the impacts of climate change.

“Together, Haley & Aldrich and ELM will have deeper regulatory relationships and technical resources for addressing the region’s urgent challenges, from remediating contaminated sites to building resilience as sea levels rise,” said Shawn Fiore, Haley & Aldrich’s president and CEO. “Our commitment to delivering exceptional value and technical excellence will remain unchanged, but our ability to deliver on that commitment will grow.”

Haley & Aldrich clients will benefit from ELM’s New Jersey-licensed site remediation professional expertise, watershed-based and sustainability-focused remedial characterization and planning experience, and expanded natural resources damage assessment and management capabilities. In turn, ELM’s clients will gain access to Haley & Aldrich’s nationwide team of more than 1,000 professionals, which offers new expertise in areas ranging from per- and polyfluoroalkyl substances remediation to deep foundation design and remedial design and construction.

“Both companies share a focus on developing a whole-system, strategic vision for contaminated sites and other projects,” said Peter P. Brussock, Ph.D., ELM managing partner. “We’ll further this vision by uniting our areas of expertise and regional experiences.”

“We look forward to introducing our clients to our expanded teams,” added Mark D. Fisher, also an ELM managing partner. “As one company, we’ll continue to prioritize the approach that we each took separately. That is, we’ll provide outstanding technical service while truly listening to our clients to learn how we can serve them best.”

Zweig Group's Mergers and Acquisitions team advised ELM through this transaction. Zweig Group is the leading research, publishing, and advisory services resource for firms in the AEC industry.
