Where does all the groundwater go? It would seem like the affects could be felt outside of Spring Valley if it’s in the water.

For those still skeptical, USACE is spending millions on monitoring groundwater around the Spring Valley/AU Park/Delacarlia. The results ain't peachy.

Agency for Toxic Substances (!) has a whole section dedicated to the Spring Valley. They note the routes of exposure to be as follows with the last one most important to soil/groundwater.

The possible pathways to result in exposure to former residents were:
 Contact with and accidental ingestion of contaminated surface soil or dust (indoor and
outdoor scenarios)
 Inhalation or skin/eye absorption of gases/vapors from release of chemicals from soil to
air
 Contamination of indoor air by entrance of outdoor air contaminants (through openings
such as garage door, windows, etc.)
 Contamination of indoor air by vapor intrusion of contaminants in soil gas beneath/beside
the house

But also. Don't drink it

Quite literally just read one, one page of USACE and other links copied and you will stand corrected on what I would translate as "you are all dumb; we don't have wells". It is not about the wellwater; it is about the groundwater under your house or landleaching into the soil, contaminating it and then you breathe that in, and it's tiresome trying to explain.

You don't have to drink it for it to get you is the point.

You know all drinking water in DC comes from the same place, right? Same pipes, too.

Apparently you and many others don't seem to be aware that houses in DC -- even large mansions in Spring Valley -- don't use wells for water.

Good encapsulation of the idiocy of these threads.

I think the person was referencing overall toxic load, but the water would be the same compared to other people living in DC. Arlington residents also get their drinking water from the same source as DC residents.

Never understood the obsession with AU Park. Just 5 minutes away you get great schools, better government, and better amenities in Bethesda -- all at comparable (and maybe even cheaper) prices. Is it just that people want the DC address?

It’s the residential area too

I think partly they just don’t know b/c they are using historic maps; then they follow modern admin borders like the streets; then they used to shoot nerve gas munition in really far and wide fans like into MoCo; and finally all sorts of soil got moved and backfilled during construction. So 🤷‍♂️

They did testing about 15 years ago of a bunch of soil and there were high arsenic levels on some blocks

It’s not great. But it depends on your personal take on the risk.

Parts of the AU are inside the USACE map. The digging at the AU is ongoing (around the PSB). Then there’s did the soil move? I guess it’s a bit safer?

This map has topography so at least you can see if you are in the way of groundwater etc.

We all saw the maps in the Spring Valley thread... which seemed to include some of AU Park. Do we think AU Park is safe?

It's like between the particles from planes in Foxhall/ Palisades/ Kent and "Death Valley" so much of the southern part of NW DC WOTP is dangerous to live in??
