There can be many reasons for housing around military bases to fluctuate greatly. Once is manpower reductions. Following the draw-down in 1991 after the first gulf war there was a huge manpower reduction. Fewer soldiers usually goes hand in hand with Government Service cuts and reduced Contracting work. Housing suffers at these times.
Now I know that chemical weapons and gases were manufactured in Aberdeen, Edgewood to be more precise. I had a friend who used to work their testing protective filters against live agents to see how long they would stand up to exposure. But I never knew or heard of Aberdeen as a storage facility for old ordnance. Johnson Atoll, an Island in the Pacific was closed awhile back after the last of the stockpiles there were destroyed. There is a place called Pueblo Chemical Depot, and a friend here says there was a depot in Idaho.
But Military bases usually have an abundance of people who don't make a lot of money. As such, their housing both on base and off is usually not as well made as is usual. Add to this that the occupants are usually temporary and don't stick around for long and the homes usually are not so well maintained.
I don't doubt that it is common belief that there is a massive stockpile of old shit buried there, but I'm not so sure that it's reality.
You can however go to this website and look at what is publicly displayed.
Click or hover over the "What We Do" tab.
There are currently two storage facilities listed.
You are quite correct that Edgewood was the primary storage place. The problem was Aberdeen was 10 miles to NE. NE is the most common wind direction. And Aberdeen is the home of ordinance testing. The whole general area is pretty bad shape.
