• 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.

All results for the week of May 12, 2008, are below the established action levels (level at which additional dust control measures must be taken to prevent the possibility of elevated lead dust levels.)
