Unlike earthquakes, weather related disasters do not normally impact water supply...
Actually, moderate to severe flooding almost always will "impact water supply."
I'll quote myself from a previous "hurricane prep" thread:
Regarding water. It doesn't take that much for the public water supply to be undrinkable. Even miles from the shoreline, torrential rain and flooding can overwhelm the city's storm drains, sewer systems, water treatment plants, etc. Flood waters carry along with them whatever was lying on the ground - trash, animal fecal matter, spilled gasoline and oil, street runoff, drowned animal carcasses, you name it. In a torrential flood, that water goes everywhere. We were in a hurricane years ago in the Pensacola area, and after we crept back into town and headed home (where we were without power for 10 days, I might add), the radio said that public officials had announced that the water supply was safe to drink; that flood waters had not contaminated it. Stupidly (we were a very young family at the time), we believed that announcement and didn't boil our water. We all got giardia (a tropical parasite, which turned out to be nearly deadly to my 1 yr-old), before a government official issued a "Whoops, sorry" warning, saying that the previous information was inaccurate, and that we should boil all our water until further notice. In fact, I've been in many hurricanes since then, and in all but the smallest storms, you can COUNT on the public water supply being undrinkable for a period of time from at least 1-4 days. DO fill up your bathtub. It's too late for you Easterners now, but many folks in hurricane country keep several empty plastic milk jugs around to fill up when a storm threatens.
This is a lesson many New York residents are currently learning, as a great many of them are under "do not drink the water because it's contaminated" orders. I sure hope they heeded warnings to stock up on water, rather than giving any credence whatsoever to naysayers telling them it was not necessary and was, rather, alarmist overkill.
After all, if it turns out you didn't need the water, what's the harm? Pour it down the sink.
The other option is that all you have to drink is contaminated water because you weren't prudent enough to stock up.
Which option seems most desirable to you?
ETA: I hope all y'all Northeasterners use this thread to check in and let us know you're fine.
I'm sure I'm not the only one that's worried.
