Brittney, every time there is a heavy rain storm, they treat the water with more chemicals, hence the smell. Even off base we get that odor, but it is definitely worse on base, in some buildings worse than others. It got so bad last year we couldn't even shower because of the fumes from the steam. Nasty.
I called the Env Quality Dept. at the hospital last year and was assured the water (on base) was safe to drink, just smelly. I have my doubts, but other than using bottled water, our options are limited.
