What Adelaide does

Adelaide Environmental Health Associates, Inc., operating as Adelaide, is a privately held, woman-owned environmental and industrial hygiene consulting firm founded in 1983 by Stephanie Soter (President and CEO) and John Soter (Senior VP). Headquartered in Brewster, New York, the firm provides hazardous material detection, abatement design, and remediation monitoring services focused on four core hazards — asbestos, lead, mold, and PCBs — delivered through consulting, inspection and sample collection, abatement design, and project monitoring/air services. A team of over twenty environmental and industrial hygienists executes projects under proprietary "ART of Hazardous Material Detection" methodology and supports ancillary services including indoor air quality assessments, industrial hygiene investigations, OSHA compliance audits, emergency preparedness planning, and ASTM-standard Phase I/II environmental site assessments.

Adelaide's client base spans public and private K-12 schools and universities, hospitals and healthcare facilities, correctional facilities, religious institutions, manufacturing and commercial real estate, and federal/state/local government agencies including the EPA, GSA, SUNY, DASNY, and NYC Department of Design and Construction. The firm is certified as a NYS Woman-Owned Business Enterprise, a Federal Women-Owned Small Business/EDWOSB, an EPA lead risk assessor/inspector firm, a NYS DOL asbestos-licensed firm, and a NYS DOL mold-certified firm, and holds approved consultant status on the NYS Office of General Services roster. It operates from three New York offices in Brewster (Downstate), Albany (Midstate), and Buffalo (Western NY), with capability to serve the tri-state area and additional US geographies, and offers 24/7 emergency response.

The business operates as a B2B professional services firm on consulting contracts, with revenue generated from project-based fees across government procurement, institutional, and commercial engagements. The go-to-motion is enterprise field sales — direct engagement with clients, working as prime or subconsultant on government term contracts and project-specific work. Pricing is not publicly disclosed. The company has served over 175 New York state school districts since 1983, leveraging long-tenured relationships and regulatory expertise (AHERA, EPA, OSHA, NYS) as primary competitive assets. No external institutional investors, M&A activity, funding rounds, or product/platform launches are recorded in the available data; the firm remains privately controlled by the Soter family.
