From first boring
to closure letter.
We handle the full remediation lifecycle — investigation, planning, agency negotiation, and closure documentation. One firm, one file, one number to call.
Phase I & II ESA
ASTM E1527-21 compliant assessments. Recognized Environmental Conditions identified, documented, and ranked by risk.
Remedial Action Planning
Site-specific RAPs drafted for agency submission. SVE, bioremediation, MNA, and excavation — engineered to close.
Regulatory Navigation
We write the technical comments, attend the agency meetings, and negotiate the risk-based standards — you focus on the deal.
Litigation Support
Expert witness testimony, cost allocation analysis, forensic source attribution. CERCLA § 107 and § 113 experience.
The clients speak.
The files confirm.
Every row below is a real engagement — contamination type, regulatory path, and timeline from first call to closure letter. Attorneys, developers, engineers. Same outcome: clean.
"We had a 19-acre brownfield under purchase agreement with a 60-day due diligence window. Remediate delivered a Phase II and preliminary remediation cost estimate before we even hit day 45. The numbers held at closing."
Marcus Delgado
Principal · Meridian Capital Partners
Former auto salvage yard. Four decommissioned USTs, BTEX plume extending 140 ft. Negotiated institutional controls with IEPA — buyer closed.
Dry-cleaning solvent plume migration dispute. Forensic dating via compound-specific isotope analysis. EPA NRCS database cross-referenced. Liability apportioned to prior operator.
"My client was facing a $4.2M cost recovery demand from a neighboring landowner. Remediate's expert report established the contamination predated our client's ownership by two decades. The case settled for $180K."
Patricia Osei
Environmental Partner · Holloway & Fitch LLP
"Three city blocks of lead paint abatement on 1940s housing stock — HUD funding, state oversight, and a neighborhood watching every move. Remediate kept us on schedule and out of the news."
James Whitfield
Capital Projects Director · City of Akron, OH
47 residential units. XRF survey, dust wipe sampling, bulk ACM sampling. Abatement specs, contractor oversight, post-abatement clearance. Zero OSHA citations.
Former metal foundry. Cadmium, lead, and arsenic in soil. Dual-phase extraction for petroleum fraction. Remediate drafted CAP, negotiated RAOs, designed SVE/AS system.
"We were 90 days from a consent order deadline with OEPA and hadn't started the remedial design. Remediate came in, took the agency relationship, and filed the design on day 87. That's the only kind of firm I'll call again."
Renata Kowalski
VP Environmental Affairs · Steadfast Industrial Group
"The EPA had our client on a Superfund NPL shortlist. Remediate's technical comments during the Remedial Investigation pushed back on the agency's risk model — successfully. We were delisted. I've never seen that done."
Thomas Brannigan
Senior Environmental Counsel · Cascades & Moreau PC
Superfund-adjacent former transformer manufacturing facility. 22-acre site. Remediate challenged EPA's cancer slope factor application. Site-specific risk assessment accepted. Client avoided $18M+ ROD obligation.
