Environmental Quality


Recent testing by the Denver Department of Public Health & Environment has found bluegreen algae may be present at toxic levels along the shoreline at Rocky Mountain Lake (3301 W 46th Ave). Bluegreen algae can produce several toxins that can make people, pets and other animals sick. Find more information on bluegreen algae on DDPHE's Water Quality page.

Environmental Quality (EQ) empowers Denver’s communities to live better, longer by creating and sustaining a healthy environment through science, service, and policy. EQ protects the environment by conducting scientific assessments, regulatory compliance, technical assistance and training, and environmental education for both private sector and city operations. EQ advocates for federal, state, and local environmental policies that protect the environment and public health. EQ prepares the city to mitigate and adapt to environmental public health emergencies.

Leading By Example

The Environmental Quality division of the Department of Public Health & Environment strives to be a leader that moves Denver to a sustainable future.

Denver is the only city nationally to have been independently certified for it's Environmental Management System, which covers all municipal operations. The City’s EMS is a best-in-class management tool that focuses an organization on critical issues, planning, implementation, tracking results and using that information to continuously improve. We use the EMS as a foundation that underpins sustainability in day-to-day City operations.

  • Over the last 15 years, the city has cleaned up 60 leaking underground storage tank sites.

  • Denver’s city operations hold 137 environmental permits for air emission sources, water quality discharges, petroleum storage tanks, and waste generator facilities.  We conduct more than 750 inspections annually to make sure we’re in compliance with our permit requirements and have a 98 percent internal compliance rate.

  • Denver owns approximately 30,000 acres of land, primarily in open space parks and street rights of ways, which is almost one-third of the city.  We are vigilant in ensuring that environmental issues on our properties are identified and quickly addressed, for the safety of our residents and workers.

  • Denver generates hazardous, electronic, and other regulated wastes at our facilities, including our fleet maintenance operations, our office buildings, and our recreation centers. Through time, our generation of these wastes has dropped by 24 percent due to recycling, change of business processes, and the use of different products and materials.
