Notes:
Highlighted indicate detections above screening levels
Grey cells indicate no measurement was collected for that specific parameter
1 - Site-Specific Public Health Screening Levels for particulate matter are based on 24-hour time-weighted
* - the screening level is the instrument's limit of detection.
1 - A secondary instrument was used to evaluate CO and reported CO as non-detected. The elevated CO measurem
CI - chlorine
F2 - fluorine
HC1 - hydrogen chloride
HCN - hydrogen cyanide
mg/m - milligrams per cubic meter
PM2 5 - particles that are 2.5 micrometers and smaller
PM10 - particles that are 10 micrometers and smaller
ppm - parts per million
TWA - time-weighted average
VOC - volatile organic compounds
