How do you measure the air? You can't hold it in your hand that's for sure. You measure it by getting the right equipment and staff, setting up monitoring stations throughout the County, and gathering results to protect the health of all Ventura County residents.


The District's Monitoring Division staff continuously monitor the air at stations in El Rio, Ojai, Piru, Simi Valley, and Thousand Oaks to determine the type and level of pollutants in the ambient air.
