Adjunct Professor Thomas Kirchstetter and PhD student, Chelsea Preble, are measuring emission rates of pollutants from trucks traveling through the Caldecott Tunnel.
California has started requiring even old diesel trucks to have new high-technology exhaust filters. "What we're doing is making an independent on road assessment of how well these emission control technologies are actually doing the job intended," Kirchstetter said.
Kirchstetter teaches in CEE's Environmental Engineering program.
