New Online Service for Registering Environmental Health Complaints: As of February 1st, Denver citizens can now register environmental complaints with the Denver Department of Environmental Health using a new online service. The city?’s official website, DenverGov.org, allows residents to report complaints regarding noise, air quality, water quality, smoking and idling vehicles, wood burning, hazardous waste, and environmental tobacco smoke using an online form located at www.denvergov.org/ehconcerns. One of the biggest advantages of electronic reporting is that you can monitor the status of the investigation of your complaint by using a complaint tracking number issued at the time the complaint is filed. Environmental complaints also are taken by telephone at 720-865-5452.
