TCE is present at Lowry in Denver, an old air force base that is now a huge development of multi-million dollar homes and townhomes.
This article is from 2000, before the housing development began. People knew TCE was there but the housing development happened anyway

It’s also at Stapleton, another huge residential area, and previously Denver’s primary airport:
“At the former Stapleton Airport, which is also being redeveloped, the TCE is 35 to 40 feet deep, according to Tom Gleason, spokesman for Forest City Stapleton Inc., the private developer overseeing the building.
He said it won't have any effect on the redevelopment, which will include homes and commercial areas.”
Indeed, it didn’t. The redevelopment happened anyway. And now I’d guess it’s in the air, water, and of course the soil.
- xadhominemx 3y agoIts 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."
- coldfoundry 3y agoJust another thing on the list of reasons I'm moving far away!
- gr1zzlybe4r 3y agoThere seems to be a crazy amount of chemical waste all over the metro Denver area. I don't live in Lowry, but I play hockey maybe once every 1 to 2 months at Big Bear Ice Arena, which is in that neighborhood. There's also the Rocky Flats nuclear site, the chemical plant in Lakewood, and also the wildlife "refuge" north of the city. Seems somewhat ironic given Colorado's reputation for pristine natural beauty.
- swasheck 3y agothe 40s and 50s were unkind to the american west and to denver, in particular. a lot of the natural beauty is actually west of denver in the places that couldnt be exploited by rockwell, lockheed, and other participants in that military/industrial complex. i also wonder how much of the environmental focus that denver-boulder is known for is something of a reaction to that exploitation.
