The research study uses Purple Air (Model: PA SD-II) sensors to study Particulate Matter (PM2.5) concentrations near roadways located in the vicinity of elementary schools and manufacturing facilities.
The research team calibrated 48 sensors at the CAMS 12 air monitoring station at UTEP. They were mounted to collect PM 2.5 data for 20 days which will be compared to the Federal Reference Method air monitoring data collected by TCEQ. In January, UTEP and UACJ began installing the network of air sensors at 31sites. UTEP installed12 sensors in El Paso, partnering with El Paso ISD. UACJ installed5 sensors in Ciudad Juárez, partnering with locations near schools and 14 sensors at manufacturing facilities.
EPA and TCEQ approved the Quality Assurance Project Plan (QAPP) for the study which ensures a rigorous scientific approach to measuring air quality.
On August 13, 2021 UTEP and UACJ submitted a report of their findings from the two-month data collection period studied by data analysis.
A key goal of the project is to enhance binational collaboration between research institutions in El Paso, Texas and Ciudad Juárez, Chihuahua.The research team meets virtually every two weeks to coordinate joint activities and implement the Quality Assurance Project Plan. The study is a first of its kind measurement of air quality in the international air basin as a whole using innovative new technology.
