Real-Time Air Data
Week of November 24, 2008
- Real-Time air (dust) monitoring (Near Field Zone monitoring) - this type of air
monitoring will determine if dust is migrating outside of the
immediate work area so that additional dust control measures can be
implemented before any dust can move off-site. This
monitoring will consist of continuous, real-time dust
monitoring upwind and downwind of the work zone during all
phases of work with potential for significant release of dust (i.e.,
during soil excavation, backfill, waste placement, and cap
installation.) Real-Time monitoring provides immediate
information on the amount of dust (not just lead) being generated.
The
real-time monitors will be moved around on a daily basis based on
the location of work activities for the day.

November 28, 2008 (working hours) -
Air Monitors 3
and 6
each
had one hourly average reading that
was above the Action Level for the area they were in.
There was no visible dust. No
additional dust control action was necessary. Co-located
samples for lead were collected at the same time as the air monitors ran.
The results for these two samples were below the detection
limit.
