Health concerns mount as more old sewer pipes are lined with plastic • Scientific American
Robin Lloyd:
<p>Earlier this year Nicole Davis arrived at one of the San Antonio, Tex., offices of the audiology practice she co-owns, ready to see the day’s patients. But upon entering her office, Davis says she quickly noticed a noxious odor that smelled like paint thinner. Her eyes started burning. By noon, she felt nauseated and dizzy, with the burning sensation spreading to her nose and throat. Her mouth went numb. Co-workers in the building told Davis that they felt ill, too. By the evening, she says, she was vomiting.

Two days later, Davis received an e-mail from an employee for a construction firm that was doing work that week on municipal pipes below street-level near the building. The employee apologized in the e-mail for Davis’s “recent experience” and attached a technical document describing the hazards and health risks associated with materials used to make plastic in the pipe project. The e-mail and attachment do not state that the work caused the odor or Davis’s reaction.

The company was renovating an underground sewer pipe with a widely and increasingly used technique called cured-in-place pipes. A felt or composite sleeve is saturated, typically with a polyester or vinyl ester resin. Workers thread the sleeve through an underground pipe and then inflate and heat it, often with steam or hot water. The sleeve hardens to form a continuous plastic liner along the old pipe’s inner walls. The technique is less expensive and takes less time than fully replacing old sewer-system pipes and stormwater culverts.

Davis has recovered from most of what she says her doctor told her were neurological effects from a chemical exposure.</p>

Clever technique but seems like they need to work the bugs out. And admit that it's going to generate lots of toxic chemicals in the short term.

The bowls at Chipotle and Sweetgreen are supposed to be compostable. They contain cancer-linked “forever chemicals.”
Testing reveals that fiber bowls contain PFAS, a troubling class of chemicals with no known half-life. It gets worse from there.
