13 Investigates first broke the story about toxic chemicals at a Walmart returns center in August.
Hundreds of workers were forced to evacuate the facility after initial tests showed the warehouse on North Franklin Road was contaminated with PCBs, chemicals that are linked to cancer.
The company that operates the center, Exel Logistics, offered all employees health testing, and we’re still waiting for those results.
The other big question: what was found in the plant? Federal investigators have released reports that include details and information about where the PCBs came from and exactly where investigators found them inside the warehouse.
The EPA released hundreds of pages of test results late Wednesday afternoon. The documents show where investigators found dangerous chemicals and the source of the contamination. The results come from testing that took place inside Walmart’s Indianapolis Returns Center in early September.

Wednesday afternoon, the EPA released a series of maps showing where PCBs were found in the highest concentrations, like in a battery charging area. It’s worth pointing out that tests throughout the warehouse show PCBs at levels that exceed government standards.
The highest concentrations were detected in caulk and paint on the floor and in some insulation material, and investigators concluded those are the primary sources of PCB contamination.
All the full-time workers at the Walmart warehouse have been on paid leave since they were evacuated nearly two months ago. 13 Investigates has learned the employees will all be moved to a different facility so operations can resume. In the meantime, those workers are waiting on personal test results to see what impact, if any, the contamination might have on their health.
See a map here (fig.1) and here (fig. 2) that shows where PCB levels were highest, as determined by the Environmental Protection Agency.
