NHDES Response to COVID-19

A clearinghouse for information related to any changes in NHDES program activity due to the novel coronavirus.

The NHDES office buildings in Concord and Portsmouth are open to the public and are accepting walk-ins, however you are encouraged to call or email the program staff and set up a meeting time before coming to the building. The NHDES main phone number is (603) 271-3503.

We also provide a locked drop box for people who would rather submit their documents (that cannot be mailed or emailed) without entering the building. Documents can be dropped off during normal business hours (weekdays 8 AM-4 PM) in the locked drop box under the portico at the main entrance door at NHDES on 29 Hazen Drive, Concord, NH (materials must fit in a 3"x 12" slot).

The DHHS water lab window is now open inside of the lobby at 29 Hazen Drive for water sample drop-offs. The main entrance to the lab is also open for the public on the side of the building.
