Low water pressure can cause contaminants to be sucked into underground pipes, a process that can expose clean drinking water to substances that are hazardous to health, like bacteria or pesticides. After water pressure increases again, it can still take a couple days for water systems to clear out contaminants.
Why do you have to boil water when pressure is low?

This boil water advisory is most common and used as a precaution, allowing time for water samples to be collected and reviewed to confirm proper water quality.
Does water boil at low pressure?
Water typically boils at 100°C when the pressure is equal to 1 atm, but when the pressure is reduced using a vacuum pump, the water boils at room temperature. When the pressure above a liquid is reduced, the vapor pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases.
