The article didn't make any concrete accusations and she was just asking for an investigation. She didn't say causation, she said correlation. "I began to think that there was an important correlation between this data and my symptoms." Even when she saw high VOCs, she didn't assume it was the remediation site. " I knew the situation was likely going to be complicated and that the tVOC readings on my personal monitors were not going to be conclusive on their own, but my gut told me something was terribly wrong." She was open to the site not being the cause. "I was thinking: If you don’t want me to be worried about this chemical’s impact to my health, you should tell me exactly why it wasn’t included in the clean-up despite being above residential limits." + "So, what made me sick? While in the end everyone agreed it was VOCs, I may never know for certain if it was the chemicals in the soil or groundwater and, if so, which ones."
Also, she mentioned a few times that doctors, government, and even Irvine Company's public relations person admitted VOCs made her sick, but just didn't know where the VOCs came from.
None of that sounds like a conspiracy theory.
