Environmental Programs

Air & Soil Pollution

Mitigating air and soil pollution are important aspects of Princeton’s sustainability goals. The campus is considered a "working lab" for the testing and implementation of sustainability efforts.  

Asbestos Management

Some University buildings constructed before 1981 have asbestos-containing components, such as pipe insulation, floor tiles and fireproofing. EHS and Facilities have a program in place to inspect such materials to ensure that they are intact, monitoring conditions, and having external, certified abatement contractors safely remove asbestos as needed.

Drinking Water Quality

Campus drinking water is supplied by NJ American Water. EHS and Facilities work together to prevent and respond to concerns regarding drinking water.

Indoor Air Quality

The quality of the air inside a building is affected by a variety of comfort, physical, chemical and biological factors.  EHS will work with you to identify and address indoor air quality concerns. 

Mold & Microbial Growth Concerns

Information on response to mold and microbial growth in University buildings can be found in the Health and Safety for the Campus Community section of the website.


Polychlorinated biphenyl (PCB) is an organic chlorine compound once used in a variety of industrial applications and electronics. PCBs are still found in transformers and other equipment containing oil or hydraulic fluid mixed with PCBs.


Princeton University has implemented a comprehensive radon testing program to measure radon levels in its residential facilities, including dormitories, its administrative and academic buildings, and other University-owned buildings.

Residential Lead Paint

Information about the University's program for control of residential lead paint hazards and whom to contact if you have questions can be found at Health and Safety for the Campus Community.
