Post-wildfire VOCs

The volatile organic compounds (VOCs) sampling results listed below are for the water samples collected after 2020 Oregon wildfires. These results include screening samples collected from locations in the distribution system to determine if VOC contamination entered the distribution system after the system was initially repressurized. Samples were also collected at service connections that lost pressure and were structurally damaged to determine if VOCs from the burnt components leached into the water. These results represent water at that location only and are not representative of water in the overall distribution system. Please note that the "Detections" and "MCL Exceedances" columns note "Yes" when one or more VOCs were detected or exceeded the MCL, respectively.
