Historical Air Sampling Report
The table linked below provides an historical summary of indoor air quality data associated with the previous detection of PCBs at the Thomas Prince School. The earlier data in the table represent pre-cleanup conditions and the later data represent post-cleanup conditions.  The two most recent post-cleanup indoor air sampling events (12/28/12 & 12/23/13) indicate that no PCB's were detected in any of the indoor air samples above laboratory reporting limits or EPA guidelines.

PCB Mitigation Update

The two classrooms that were designated as pilot sites in order to establish an effective method to reduce PCB levels at Thomas Prince have now been tested and are well within the acceptable limit of 300 nanograms per cubic meter.  The most recent test showed 179 nanograms per cubic meter in the second pilot room.  At this point, Environmental Consultant Services, Inc., which is Princeton's consultant, will file a report with the EPA and seek authorization to clean the remaining six contaminated classrooms using the same methodology that has proven successful in the pilot rooms.  Once cleaned, we will proceed with further air testing which will pave the way to occupation of these rooms.
