State officials trace the problem back to October 2015.
Costco brought in pallets and pallets of water to meet the demand for supplies during the close calls we had during last year's hurricane season.
But customers across the state are just finding out those bottles are being rejected by recycling centers because they don't have the proper HI-5 labels.
"I hadn't heard of it. I'm not sure if I have any that come from Costco,” said Debbie Snell who dropped off two bags full of containers.
Neither did another man who had two large garbage bins full of Kirkland bottles.
