Is Trichloroethylene (TCE) in Your Home? Here's How to Know for Sure
✓ Your concern is understandable. Trichloroethylene (TCE) is present in more homes than most people realize, and you're doing the right thing by researching it.
You're not overreacting. Trichloroethylene (TCE) is invisible and odorless — the EPA recommends every homeowner test for it regardless of age or condition of the home.
The test kit below can tell you in 48 hours whether your home has elevated levels. Testing is the only way to know for sure.
Trichloroethylene (TCE) is a high-severity indoor air quality hazard that the EPA classifies as a significant health risk. It is most commonly found in basement, crawl-space, living-room and originates from vapor intrusion from contaminated groundwater, industrial solvent residues, older dry cleaning facilities nearby.
Industrial solvent found in some older homes near contaminated sites. Linked to cancer at low exposures. TCE vapor can seep into homes from contaminated groundwater and soil through a process called vapor intrusion. EPA classifies TCE as a human carcinogen.
Your family may be breathing trichloroethylene (tce) right now.

Symptoms to Watch For
If you or your family members are experiencing any of these, trichloroethylene (tce) could be the cause:
Quick Reference Data
| Hazard | Trichloroethylene (TCE) |
| EPA Severity | HIGH |
| Common Sources | vapor intrusion from contaminated groundwater, industrial solvent residues, older dry cleaning facilities nearby, metal degreasing operations, contaminated soil near former industrial sites |
| Affected Areas | basement, crawl-space, living-room, bedroom |
| Health Symptoms | headaches, dizziness, nausea, facial numbness, liver and kidney damage with chronic exposure, increased cancer risk especially kidney cancer, immune system effects |
| EPA Recommendation | If you live near a former industrial or dry cleaning site, test your indoor air for TCE. Contact your state environmental agency for vapor intrusion assessments. Install vapor mitigation systems if detected. Do not ignore musty or sweet chemical odors in basements. |
Your Children Breathe 20,000 Liters of This Air Every Day
Kids breathe more air per pound of body weight than adults. Their lungs are still developing. If trichloroethylene (tce) is in your home, they're getting a higher dose than you are. You childproof cabinets and plug outlets — but have you checked what they're breathing?
⚠️ The EPA estimates indoor air can be 2–5× more polluted than outdoor air. Your family breathes 20,000 liters of indoor air every day.
If trichloroethylene (tce) is present, every breath could be doing damage you can't see or feel — until it's too late.

📋 Our Testing Methodology
Hazard severity classifications follow the EPA's Indoor Air Quality assessment framework:
- • Critical: Immediate health risk — evacuate and contact emergency services
- • High: Chronic exposure risk — test within 1 week, remediate within 30 days
- • Moderate: Potential risk — test to confirm, address if confirmed
Product recommendations are based on published detection accuracy, third-party test results, and EPA-recommended testing methods. Updated May 2026.

If your home has trichloroethylene (tce), there's a chance it also has volatile organic compounds (vocs). Both can thrive in the same conditions. When you test for one, check for the others too.
Related Hazards
Volatile Organic Compounds (VOCs)
VOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Basement Air Quality Hazards
Basements accumulate the worst indoor air hazards: radon, mold, chemical storage fumes, and pest allergens. Because warm air rises, basement pollutants circulate throughout the entire home through the stack effect.
Formaldehyde (VOC)
Formaldehyde off-gases from pressed wood furniture, flooring, and new construction materials. It is classified as a known human carcinogen by the IARC. Levels are highest in new or recently renovated homes.
How Trichloroethylene (TCE) Compares to Related Hazards
Trichloroethylene (TCE) carries a HIGH severity rating — the second-highest tier. Compared to related indoor air hazards, 0 are rated more severe and 0 are rated lower. All demand attention, but the testing and remediation sequence depends on which hazards share your home's risk profile.
Both Trichloroethylene (TCE) and Volatile Organic Compounds (VOCs) carry the same high severity classification. Their combined presence in your home creates a compounding effect that exceeds the risk of either alone. Addressing one without testing for the other leaves a blind spot in your home's air quality.
Both Trichloroethylene (TCE) and Basement Air Quality Hazards carry the same high severity classification. Their combined presence in your home creates a compounding effect that exceeds the risk of either alone. Both are commonly found in basement. Addressing one without testing for the other leaves a blind spot in your home's air quality.

What Your Trichloroethylene (TCE) Test Results Mean
After testing for trichloroethylene (tce), you'll receive a measurement or a positive/negative result. Here's how to interpret what that number means for your home and family.
Below Detection
No trichloroethylene (tce) was detected. Continue routine monitoring — high-severity hazards can emerge as conditions change.
What to do: Re-test every 6-12 months. Pay particular attention to vapor intrusion from contaminated groundwater and industrial solvent residues, which are the most common entry points.
Low-Level Detection
Low levels of trichloroethylene (tce) were detected. While not immediately dangerous, chronic exposure to a high-severity hazard compounds over time — especially in basement and crawl space.
What to do: Identify the source among: vapor intrusion from contaminated groundwater, industrial solvent residues, older dry cleaning facilities nearby. Improve ventilation and re-test in 2-4 weeks. If you live near a former industrial or dry cleaning site, test your indoor air for TCE.
Elevated / At Action Level
Trichloroethylene (TCE) levels have reached or exceeded the action threshold. At this level, the EPA recommends if you live near a former industrial or dry cleaning site, test your indoor air for tce.
What to do: Schedule professional testing within 1 week. Begin source remediation within 30 days. Do not ignore — high-severity hazards do not resolve on their own.
Interpretation guidelines are based on EPA standards for chemical hazards. For trichloroethylene (tce), if you live near a former industrial or dry cleaning site, test your indoor air for tce. Always confirm results with a certified professional.
