What is the Billings PCE Superfund Site?
The Billings PCE Superfund Site spans through neighborhoods west of downtown Billings, between Central Avenue to Grand Avenue.
It originated from dry cleaning and industrial operations that released PCE (tetrachloroethylene) into the environment. Over time, PCE and its breakdown products (TCE and cis-1,2-DCE) contaminated groundwater and created the potential for vapor intrusion into buildings above.
Why this matters: Breathing these vapors over time may increase the risk of cancer, liver and kidney damage, and neurological effects.
📍 Check If Your Home is in the Impact Zone
The EPA offers an interactive map of the Billings PCE Site where you can:
- Enter your address
- Zoom in/out to see your neighborhood
- View boundaries of the contamination plume
🆓 Free Property Testing & Mitigation
If your home or business falls inside the plume, you may qualify for free vapor intrusion testing and, if needed, a no-cost mitigation system.
How it works:
- The EPA installs a sub-slab depressurization system (similar to radon mitigation) to redirect vapors away from your home.
- Installation & maintenance are free — the only cost is electricity to run a small fan (about the same as a 75-watt light bulb).

💬 FAQs
Q: What is PCE?
A: PCE (perchloroethylene) is a chemical solvent often used in dry cleaning. It can seep into soil and groundwater and turn into harmful vapors.
Q: Is my water safe?
A: Billings residents are served by the city water system, which is treated and safe. The main concern is vapor intrusion from contaminated groundwater, not drinking water.
Q: How do I know if my home needs mitigation?
A: Request free testing from the EPA. Results will determine if a system is needed.
Q: Will mitigation affect my property value?
A: Having mitigation in place can protect your health and give buyers peace of mind, which can be a selling point.
