General

How do I report a release?

How do I view Remediation Division files?

Remediation documents can be found in the REACT portal (REACT Resources and Instructions). In general, documents submitted in and after 2026 should be accessible in REACT. Documents submitted before 2026 can be found in the DEEP Online Document Search Portal. Please see Remediation Division documents for information on how best to locate documents.  

Brownfields

I am interested in buying an old industrial site for redevelopment. Is there someone who can help with this process?

There are many resources for helping with redevelopment at brownfields sites.  The Department’s Brownfields webpage has useful information and links.  If the municipality has a development office, that may be a good starting point.  The Department's Brownfields Coordinator and the Connecticut Department of Economic Development (DECD) Office of Brownfield Remediation and Development may be able to discuss your situation with you or refer you to other resources.

Does DEEP have funding for Brownfield clean-up?

DEEP periodically has federal grant funds to award to municipalities and non-profits, which are posted at Grants and Financial Assistance when available. There are also a number of potential funding sources and programs offering liability relief.  The Connecticut DECD Office of Brownfield Remediation and Development provides financing and technical resources for cleanup and redevelopment of brownfields.

State agencies such as the Department of Economic and Community Development (DECD), the Connecticut Development Authority (CDA), and local entities, such as the Naugatuck Valley Development Corporation (NVDC), might be able to provide financial assistance.

Potable Water

I would like to have my well water tested.  Will DEEP provide this service?

No, unless you have reason to believe that your water supply has become polluted by a substance that is not naturally occurring.  Evidence of pollution may include a distinct gasoline, heating oil or chemical odor, or a significant change in the color or quality of your water, particularly if you are located near potential sources of pollution like a gas station, dry cleaner, or landfill. PFAS Information for Private Well Owners contains information on how and when to test private wells for PFAS.

DPH’s Private Well Program has information about naturally occurring contaminants, well water testing, and/or water treatment options.  A list of State Approved Commercial Environmental Laboratories, including those that can perform routine well water testing, can be found on the Department of Public Health website.

I had my water supply well water tested and the my well is polluted with a non-naturally occurring substance, what should I do next?

Contact your local Health Department or Health District to review the results or contact the Remediation Division at (860) 424-3705 and ask to speak to the supervisor for the district in which your town is located.  If your well water contains Road Salt, follow instructions on that page.  If you have confirmed PFAS contamination in your private well, email DEEP.PFAS@ct.gov about treatment options and investigation.

Property Transfer

I’m selling a property that had previous property transfer forms filed. Will form filings be required when I sell the property?

No, although all establishment transfers that occurred before March 1, 2026 do require form filings.

What happens to Property Transfer sites now that the program has ended?

Sites that have not been investigated, cleaned up, and verified will continue to be cleaned up under the Property Transfer Program. Once remediation at a Property Transfer site is complete and a final verification is accepted, any releases that occur after the applicable date of that verification will fall under the Release-Based Cleanup Regulations.

Once the site has been investigated, there is the opportunity to transition from the Property Transfer Program to the Release-Based Cleanup Program by submitting an Release Catalogue Report.
