Other hospital demolition updates:
The removal of the additional soil from the location of the 6,000 gallon #6 heating oil tank and the installation of the new monitoring well is complete. A sample from the monitoring well was taken and test results are anticipated to be available in the next few days. Additional sampling of the well will be scheduled in mid October due to insufficient water in the well to obtain a representative sample now, officials said.
A building permit has been issued by the town to allow for repairs to be completed at the former hospital parking garage. During the repairs, the garage will remain open for limited parking. Three sections of the upper deck have been replaced and additional sections are being prepared for replacement. Repairs will take another six months.
The site continues to be monitored on a regular basis by local officials, state officials, and a consultant.
Avalon Bay is having staff walk through the neighborhood each day, if needed, to pick up litter.
Avalon Bay’s acoustics consultant, Cerami & Associates, continues to monitor noise levels at the site. The Princeton Health Department is working alongside the Mercer County Division of Public Health to provide additional noise monitoring. A temporary sound absorbing wall and sound absorbing blankets have been installed adjacent to where the upper concrete floor deck of the garage is being removed. Avalon Bay is also investigating ways to mitigate noise created by the jackhammering of concrete from the structural beams of the building. This work will not continue until acceptable mitigation measures are taken, officials said. Any noise related complaints should be directed to the Princeton Engineering Department, or the Princeton Police nights and weekends. The Mercer County Health Department and the Princeton Health Department will be taking additional noise measurements as the work proceeds, officials said.

Air quality monitors continue to be checked and have been found to be well below allowable thresholds, officials said.
