Indoor Air Quality


Indoor Air Quality The Environmental Protection Agency (EPA) has identified indoor air quality as one of the top five most urgent environmental risks to public health. The EPA states that levels of air pollution inside the home can be two to five times higher - and occasionally up to 100 times higher- than outdoor levels.

Air pollution contributes to lung disease, including respiratory tract infections, asthma, and lung cancer. Lung disease claims close to 335, 000 lives in America every year and is the third leading cause of death in the United States. In addition, people who may be exposed to indoor air pollutants for the longest periods of time are often those most susceptible to the effects of indoor air pollution. Such groups include the young, the elderly, and the chronically ill, especially those suffering from respiratory or cardiovascular disease.

Indoor air pollution is one risk that you can do something about. While pollutant levels from individual sources may not pose a significant health risk by themselves, most homes and offices have more than one source that contributes to indoor air pollution. There can be serious risk from the cumulative effects of these sources.



The Weld County Department of Public Health & Environment may assist with complaints and concerns raised about structures that are routinely open to public access (government buildings, schools, churches, commercial buildings, etc.) in both incorporated and unincorporated Weld County.

For assistance with issues or concerns in residential homes, including multifamily residences, or those buildings not open to public access, please defer to the resources found on the right side of this page (under Outside Links) or contact a qualified consultant or contractor.
