If you still have water running in your home, you might think about saving some of it. And boil it before you drink it.
Some dopey contractor ruptured a main water main and water to the city is off for 24-36 hours. Water service is out, but until they get the pipes all filled with water and conduct tests that confirm its ok, they'll leave it in effect.
Fill up some pots, boil the water and stick it in the fridge. And don't use the ice either. Use those ice cube trays you stored away and use your boiled water to make ice.
This is likely more a precaution than a real threat. You swim in the ocean and swallow water and you don't get sick. You don't disinfect your home every 10 minutes. There are germs everywhere.
