Calls and complaints to the Department continue to identify localized air quality problems. Environmental Impact Sources Traffic densities on highway and arterial roads in Madison continue to increase and are a significant source of air pollutants, including airborne particulates. Measurement of hazardous air pollutants is not performed consistently. MDPH continues to receive more than 200 calls and complaints on indoor and outdoor air quality per year and is working with state and federal agencies to address these problems. MDPH enforcement of Madison s smoke-free restaurant law has helped reduce exposure to secondhand smoke.
Efforts are currently underway to enact a smoke-free workplace ordinance as well.
Regional surface ozone continues to be a threat to Madison s air quality. Transportation sources of ozone precursors continue to increase as Madison and the surrounding communities grow.
