Guidance Documents Vapor Intrusion VI Template Letters & Results Tables

 

Vapor Intrusion Template Letters & Results Tables

Whenever vapor intrusion testing has been conducted at a private property during the remediation of a contaminated site, the person responsible for conducting the remediation should make certain the property owners and any occupants (i.e. tenants) are notified of their results in writing. A Licensed Site Remediation Professional (LSRP) or other authorized party may send the letters on behalf of the person responsible for conducting the remediation.

At a minimum, the vapor intrusion testing result letters should consist of a cover letter that summarizes the findings along with a table of the analytical results. The New Jersey Department of Environmental Protection has developed the following template letters and tables to notify property owners and occupants of vapor intrusion testing results for three common vapor intrusion investigation scenarios: sub-slab soil gas testing only, indoor air testing only, and sub-slab soil gas testing performed concurrently with indoor air testing.

Additional Template Letters

Due to the complexity of vapor intrusion investigations, it is not possible to provide template letters or tables that will address all possible circumstances. These template letters provide basic outlines for the most common vapor intrusion investigation scenarios, and may need to be modified to address specific situations.

It is important to note that use of these template letters and tables is optional. If you choose to use your own cover letters and/or tables, please make every effort to provide the information in terms that are understandable to the layperson. The cover letter should clearly summarize the sampling results for the property owner/occupant and discuss the next steps. Furthermore, the information conveyed to the property owner/occupants must not minimize the urgency to address the vapor intrusion issue nor downplay the source of the contamination.
