Haley & Aldrich

What Haley & Aldrich does

Haley & Aldrich, Inc. is a U.S.-based environmental and geotechnical engineering consulting firm founded in 1957 and headquartered in Burlington, Massachusetts. The firm delivers multidisciplinary professional services spanning contaminated site management and remediation, environmental due diligence and risk assessment, geotechnical engineering, EHS compliance, brownfields redevelopment, construction management, disaster and climate resilience, water resources, and sustainability consulting. It serves nine primary verticals: aerospace, data centers, education/healthcare/cultural institutions, energy, environmental trusts, government infrastructure, industrial/manufacturing, mining, and real estate developers, with named and confidential clients across federal, state, and local government agencies (U.S. Air Force, DOD, U.S. Forest Service, County of Maui, Hawaii DOT, Port of Tacoma, Alameda County), utilities and energy companies (Southern California Edison, Republic Services), universities and hospitals (Boston University, Wellesley, Spaulding, Cal Poly), industrial manufacturers, and private real estate developers (Toll Brothers, Samuels & Associates).

The firm's underlying technology base is centered on senior consulting expertise augmented by a proprietary Applied Research program whose flagship output is EradiFluor, a zero-waste PFAS-destruction technology developed for groundwater remediation and currently being field-tested with the U.S. Air Force. Service delivery is organized around market leaders, service leaders, and principal consultants across offices in at least Burlington (HQ), Rochester, and Phoenix, with national coverage across more than 20 U.S. states. Notable delivered outcomes include a $300 million risk-based closure plan for a major airline, $200 million saved for an oil and gas client, approximately $90 million saved through cost allocation modeling, and removal of over 96,000 tons of hazardous waste at Kingman Airport in Arizona.

Haley & Aldrich operates a fee-for-service professional services revenue model with project-based, quote-driven engagements priced on scope, complexity, and duration; no public pricing tiers or rate cards are disclosed. The go-to-market is direct enterprise and field sales led by senior market and service leaders with an average tenure of 16 years, supported by content marketing, technical publications, case studies, and a modest organic social presence on LinkedIn, Twitter, and Facebook. In September 2024, the firm acquired The ELM Group, a Pennsylvania/New Jersey-based environmental consultancy, marking its first documented inorganic expansion into the mid-Atlantic region. The company is privately held with no publicly disclosed parent, private equity sponsor, or institutional investors.
