The following day the police were called back to investigate more reports of meth, including inside the motel's ice machine.
Due to the ice machine being plumbed into the mains water supply, concerns were raised that there was wider contamination
"It was later found that a large amount of methamphetamine had been introduced to the building's water system and then continued throughout the building," police said.
"The City of Portales has cut the water service to the building to stop the potential for contamination of the City's water supply and to protect those still occupying the building.
Further testing of the substance was inconclusive and the police investigation continues with local police involving New Mexico state authorities and reassuring the public that the city's water supply was safe.
