Good evening Chris and Colin,
Please find below an update of events for the 8/28 8am to 8/29 8am:
Bainbridge performed air monitoring ( 7am to 7pm) at 19 stations throughout the day and
analytical sampling at one station.
1. The 24-hr TWA (from 8/28 to 8/29, 8am-8am) for PM10 concentrations from the
DustTraks were as follows:
Around the immediate vicinity of the hangar (DU1-DU12) ranged from 16.05 to 31.04
µg/m3
Around the outer perimeter and community (DU13-DU21) ranged from 21.12 to
37.77 µg/m3
2. Community sample from DU20 collected today for laboratory analysis and will be
reported in subsequent emails once results are available. Sample results collected from
8/22 through 8/24 have been received and no asbestos was reported in the sample or
field blanks collected. Sample results and COC can be found in the Sharefolder under
the Bainbridge tab.
3. Other observations for the day included:
Prevalent wind on the site once wind speeds were at or above 5 mph came from the
west, southwest and south and ranged from 0 to 22 mph as recorded by the weather
station attached to DU01.
Additionally, attached is the data for the 18 monitors without the weather station and DU01
with the weather station, which includes the minimum and maximum reading for each unit as
well as the 24 hr TWA calculation, Bainbridge calibration log for 8-28, and Wind Rose diagram
from 8-28.
