Co-located Lead Samples December 2008 

• Co-Located Lead Samples - this type of air monitoring consists of air monitoring for lead using personal air monitors (PAMs).  For this monitoring, the PAMs were placed at the same location as the Real-Time (Dust) Air Monitors.  This sampling is in addition to what is required by the 100% Design.  The samples were analyzed by a method that provides a detection limit similar to the detection level that is used for the perimeter high volume air samplers. This will allow us to compare the co-located sample results with the results that we obtain every six days from the perimeter high volume air samplers. Initially, we will use the data from the co-located samples to compare with the information being obtained from the dust monitors and as we move forward, the co-located samples will be helpful in providing data in the event that a future exceedance occurs at one of the dust monitors.

The real-time dust monitors are moved around on a daily basis based on the location of work activities for the day; the co-located samples are located with the dust monitors each day.
