Ozone Monitoring

A correlation between ozone levels and poor dye performance has been noted anecdotally and within the literature. To assist investigators in monitoring those levels we've set-up these pages to obtain the most up-to-date O3 monitoring information from US EPA and the Michigan Department of Environmental Quality (MDEQ).
