Federal officials commandeered the area in the far east of the island last fall as a staging ground, collecting the water and containers full of tarps to patch damaged and destroyed roofs in surrounding neighborhoods.
And apparently, the supplies were just left there, lost perhaps in poor communication and collaboration.
FEMA handles getting the supplies to the state or commonwealth, who in turn handle distributing those items at a local level, said Jeff Byard, FEMA Associate Administrator for Response and Recovery. "Obviously with Maria, we had not a supply issue, we had distribution issues," he said during a briefing about Hurricane Florence.
Ottmar Chavez, now administrator of Puerto Rico's General Services Administration, said FEMA reported that it had about 20,000 pallets of bottled water in excess in May this year, before Chavez was appointed.
His agency claimed the water, intending to deliver it where it was needed.
But after about 700 pallets had been distributed, complaints began to come in about the water's foul smell and taste, Chavez said in a statement.
"In light of this, we have been in contact with FEMA and the Department of Health to test the water inventory received by the federal agency. We are going to return those waters," he said.
The mayor of Ceiba, Angel Cruz Ramos, told CNN he's grateful for the generosity, but believes that too much water was delivered at the wrong time. "The time and heat has made it bad," he added.
