Are You in the Project Area for Indoor Air Testing?
Is Your Property Included?
The indoor air testing areas were determined based on soil vapor assessments in the neighborhood. Only locations that showed the need for additional testing are included in the current testing zones.
- Check the map to see if your property is in a marked testing area.
- Properties inside the marked zones are eligible for free testing.
- Properties outside the marked areas don’t need testing based on previous results that show no pathway to exposure.
- If you’re unsure whether you’re in the testing area, send your address to 29grove@up.com or call 866-896-7511.
What Happens Next?
If your property is in the testing area:
- You should have received a letter with an access agreeement.
- The property owner must sign this agreement before testing can begin.
- We’ll work with both owners and tenants to schedule convenient testing times.
- All testing is free of charge.
Timeline for Testing
After Testing is Complete
We’ll share results with you promptly.
If the results show air quality meets KDHE quality standards:
• No further action will be needed.
If the results are above the safety threshold set by KDHE:
• Union Pacific will work closely with you to eliminate any
hazards and/or improve indoor air quality.
• We may recommend solutions such as:
- Sealing cracks in basement walls or floors.
- Sealing sumps.
- Installing ventilation systems.
- Other actions specific to your home’s needs.
• Union Pacific will cover all costs for testing and any needed follow-up actions.
Understanding What Led to These Tests
During the 1970s or 1980s, there was a trichloroethylene (TCE) spill in the railyard, which was first discovered in 1994. The TCE is now present in a groundwater plume about 14 to 20 feet underground, extending about 2.9 miles south from the rail yard to Murdock Avenue.
Important: Your drinking water is NOT affected. Wichita’s public water supply comes from different sources that are regularly tested and treated.
About TCE and Remediation
TCE is an industrial solvent used to clean metal parts. While it can also be found in some household products, it’s the main contaminant we’re monitoring in the 29th & Grove area.
Is the Situation Under Control?
Yes. Here’s what you should know:
• The groundwater plume is not spreading.
• Our monitoring shows the TCE levels have steadily decreased over the
years.
• Remediation efforts over the past 20 years have reduced the levels of
contamination in groundwater.
• We’re installing new treatment systems to speed up TCE removal from
the groundwater.
