Sites with a past: environmental consulting in Connecticut
You're buying a property with a gas station in its history. Or your plant has had an open Transfer Act filing since the 1990s. Or a Phase I turned up a tank nobody has paperwork for. Connecticut has rules for each of these, and in March 2026 the rules changed.
ZUVIC finds out what's actually in the ground, what the state requires of you, and the most direct way to get to a closed file, a sale, or a building permit.
ZUVIC Inc. is a Rocky Hill, Connecticut engineering firm. Our environmental team, led by two Licensed Environmental Professionals, handles Phase I-III site assessments, Transfer Act and Release-Based Cleanup Regulations cases, remediation and compliance for operating facilities.
The report isn't the finish line. The closed file is.
Our LEPs
The LEP who plans it signs it.
In Connecticut, a Licensed Environmental Professional (LEP) is the person the state authorizes to sign off that a site meets its cleanup standards. ZUVIC has two:

Victoria Man, LEP
Has led ZUVIC's environmental practice since 2009.

Daniel Pinho, LEP
Is also a Connecticut-licensed asbestos inspector and management planner.
The LEP who scopes your investigation is the one who signs the verification at the end. There's no hand-off halfway through, and no one new learning your site in year three.
Services
What we do.
Due diligence and site assessment
Before you buy, lend or sell, we find out what the property's history left behind.
- Phase I, II and III Environmental Site Assessments
- Transaction due diligence for buyers, sellers and lenders
- Sensitive receptor surveys and vapor intrusion evaluation
- Hazardous building materials surveys (asbestos, lead paint, PCBs) before renovation or demolition
Connecticut cleanup programs
The Transfer Act, the new Release-Based Cleanup Regulations, the Remediation Standard Regulations: we work out which rules apply to your site and take it through them.
- Transfer Act / Property Transfer Program filings and case management
- Release-Based Cleanup Regulations (RBCR, in effect since March 1, 2026): evaluation, reporting, and comparison with an existing Transfer Act pathway
- Remediation Standard Regulations (RSR) compliance and groundwater monitoring
- LEP verifications
- Environmental use restrictions and engineered controls (caps and other measures that let you build safely without removing all the soil), including annual reporting
- Significant Environmental Hazard notification, response and closure
Remediation
When something has to be cleaned up, we design the cleanup and oversee it.
- Remedial action plans and cleanup cost planning
- Excavation oversight and soil management plans
- Soil vapor extraction and air sparging
- In-place treatment, including chemical oxidation and injection programs
- Oil (NAPL) delineation and recovery system design
- PCB investigation and cleanup under the federal TSCA rules
- Underground and aboveground storage tank closures
Compliance for operating facilities
For plants, depots and campuses that have to stay open and stay in permit.
- SPCC (spill prevention) plans
- Stormwater pollution prevention plans and industrial stormwater general permit compliance
- Construction stormwater inspections
- CT DEEP discharge and injection permits, including groundwater remediation discharges to sanitary sewer
Funding and expert support
- Brownfield funding support, including regional revolving loan funds and EPA brownfield grants
- Litigation support and expert witness services
Projects
Representative work.
Turning former fuel terminals into a campus
For Goodwin University's $38 million Riverside Campus, ZUVIC has investigated and cleaned up former petroleum terminal parcels along the Connecticut River in East Hartford. The work has included soil vapor extraction, in-place chemical treatment and years of groundwater monitoring as the University expanded onto the riverfront.
Oil under an operating plant
For a manufacturer on filled harbor land, ZUVIC rebuilt three decades of site records and found and sampled the legacy wells. It then drilled new borings inside the running plant to map oil on the water table and planned the recovery system. The site has been in the Transfer Act program since 1996, and the work now includes the choice between that program and the new release-based rules.
A petroleum release that has to be handled now
A gasoline tank removed years earlier had left petroleum into shallow bedrock groundwater within 200 feet of a supply well. ZUVIC's LEPs took the owner from Phase I through a state-permitted injection and a year of monitoring. In December 2021 CT DEEP certified the hazard resolved, after a single round of treatment.
A school site closed with no deed restriction
A 4.23-acre parcel of old parking, farm fields and an electrical substation became Goodwin's Pathways Academy magnet high school. ZUVIC cleaned it to residential standards while the school was being built, and CT DEEP closed it with a Letter of No Audit in 2016.
A substation closed under the new state rules
For Eversource, ZUVIC took a decommissioned substation from Phase I through cleanup, four quarters of groundwater sampling and, in August 2026, an LEP verification of closure under Connecticut's new Release-Based Cleanup Regulations.
FAQ
Questions we hear.
My site has been in the Transfer Act program for years. Do the new rules change anything?
They can. Since March 1, 2026, Connecticut's Release-Based Cleanup Regulations set a different path from the Transfer Act, and some owners are better off on one than the other. We compare the two for your site: what's required, in what order, and on what timeline.
Can I build on a site that isn't completely clean?
Often, yes. Depending on the site, a cap, a vapor barrier or a recorded use restriction can make it safe to build without removing every yard of soil. When the cleanup goes deep enough, as it did at the Pathways Academy site, no restriction is needed at all.
Do I need a Phase I before I buy?
If you're borrowing to buy, your lender will almost certainly require one. Even with cash, a Phase I done to the current federal standard (ASTM E1527-21) is what protects a buyer if contamination turns up later.
I'm not sure I have a problem at all.
