DOH: Trace amount of toluene detected in Upper Kula water system : Maui Now
The presence of toluene was detected after the Upper Kula Wildfire in August of 2023. This strongly suggests its presence was an artifact of the wildfire impacting the surface water source for the Upper Kula Treatment Plant, according to the DOH. Further monitoring is planned by MDWS at the Upper Kula Treatment Plant.
