June was a pretty good month with regard to ozone levels, possibly due to the rains the region experienced. The only monitors that experienced moderate levels were the Conroe monitor and UH WG Jones Forest monitor, and that was at the beginning of the latest bi-weekly period.
Ozone forms when a mixture of chemicals, mostly from tailpipes and smokestacks, reacts in sunlight. Exposure to the pollutant can lead to asthma attacks, heart disease and even premature death.
Residents can help prevent ozone pollution by sharing a ride or carpooling, walking or riding a bicycle, taking your lunch to work, avoiding idling your engines at schools and in drive-through lanes, conserving energy, and keeping your vehicle properly tuned.
When high ozone is predicted, the EPA and Texas Commission on Environmental Quality (TCEQ) issue alerts, which are announced online and via email. TCEQ issues a daily air quality forecast taken from EPA and AirNow and announces ozone actions days online. You can also sign up for email or text alerts from TCEQ. TCEQ’s Twitter account also posts the daily air quality forecast during the week.
