January 6-9, 2025: The follow-up chemical analysis for the week of January 6, 2025 detected lead above the conservative threshold selected for this work site of 0.15 ug/m3 at meter location 3.
- Notes:
  - The monitor had been knocked off its stand during the collection period which may have impacted the results.
  - T
    here were no exceedances of other chemical action levels at any other perimeter monitors or worker personal monitors.
  - Actions have been taken to ensure dust is controlled within the work area and increase the use and thickness of posi-shell.
  - It is important to note that the threshold for lead is set very low at this work site to protect the health of the workers and the community, and there is no health risk to the surrounding community. The threshold of 0.15 ug/m3 currently used at the site is the National Ambient Air Quality Standard for lead and is normally used over a 90-day period. To be extremely protective of health, this project is using this number over a single work day. The current average concentration of lead for the Raybestos Memorial Field work period to date is currently well below (approximately 14X below) the National Ambient Air Quality Standard for lead.
