More than a third of Puerto Rican households, or about 1 million people, still lack running water according to CNN.

FEMA says it has distributed 23.6 million liters (6.2 million gallons) of bottled and bulk water in Puerto Rico. That figure includes water for hospitals and dialysis centers

These deliveries equate to only 9% of the island’s drinking water requirement, going by the World Health Organization’s (WHO) assessment that each person needs at least 2.5 liters (2/3 of a gallon) per day. Some residents are so desperate for drinking water they have broken into polluted wells at industrial waste sites.
