North Dakota DEQ publishes this personnel list and states that it is not all-inclusive and is not an endorsement. City is a service city on the DEQ list; some people appear under more than one city and are shown once, using the first city of record.
Always verify the credential is still current with North Dakota DEQ Indoor Air Program (current personnel PDF) before hiring. This index does not rank contractors or take referral fees.
