Its certainly in the soil and groundwater - but why would it be in the air?
- ta988 3y agoBecause it is volatile.
- runjake 3y agoBecause water evaporates and TCE is particularly good at transmission through water vapor. That's my guess.
- aurizon 3y agoWater vapor is co-distilled with water vapor in room temperature evaporation. Humid air a 70F has a partial pressure of about 0.2 PSI - a substantial amount. I would have to look into tabular data on the H2O TCE system to see, but it is substantial = the smell you get. It also has it's own presence on dry air, but it is higher if water present due to low temperature co-distillation. These soils need to be dug up -washed with super-critical CO2 ($$$), then baked dry with the vapor condensed. This has been done in Toronto at a few old factories. Later they started to create a large underwater landfill area - the 'spit' and created a number of clay and membrane lined lagoons(embayments) where they buried it and covered it with clean fill to make a wild life area. Started about 50-75 years ago and it was well built and monitored since then and has stayed sealed.https://en.wikipedia.org/wiki/Leslie_Street_Spit https://en.wikipedia.org/wiki/Leslie_Street_Spit
- anjel 3y agoIt's no longer uncommon to (carbon) filter drinking water at the tap or in your fridge, which then makes a hot shower likely a major avenue into your body by way of your lungs unless you filter water for the whole house plumbing system.
- xadhominemx 3y agoThese developments are not pulling local groundwater.
- TedDoesntTalk 3y agoDoesn't matter - it's in the air, too. Read the article.
- explorer83 3y agoThere are shower heads that can be installed with carbon filters. Can be done with a wrench. No plumber required.
- CapstanRoller 3y agoThere are bubble domes you can live in, too, but that doesn't really address the underlying problem.

- TedDoesntTalk 3y agoIf you read the TFA it says, "TCE is highly persistent in soil and groundwater; inhalation through vapor from these hidden sources is likely the prime route of exposure today."
