Real-Time Air Data
Week of September 1, 2008
- Real-Time air 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.
