SAN ANTONIO -- Two miles from a cement plant, residents woke up to find their cars covered in thick powder.
But residents are not just complaining about the mess, but alleged breathing problems too.
So what is the mystery dust? KENS 5 has learned the Texas Commission on Environmental Quality is stepping in to find out.
"They say it comes from the cement factory," said Jason Pascale. "It definitely covers everything."
Pascale lives in Stuebing Ranch where the subdivision appears to be having a white October. But it's not snowing. Pascale suspects this is no ordinary dust.
"No its not dirt," he said. "It's definitely cement," he said as he swiped his finger across his truck.
The Home Owners Association says it's contacted the nearby Alamo Cement Company about the powdery substance.
A spokesman for the company said north winds, Friday, picked up dust every where but maintains nothing came from their stack.
"The company has never had a complaint like this before," said Larry Alexander in an off camera interview with KENS 5. "Alamo is working with the residents and HOA to get cars clean," he added.
"It took the clear coat off his brand new car," Pascale said about his neighbor's new car.
He says he fears that if the mystery dust can cover the coat of a car, what could it possibly be doing to his lungs?
"I've had respiratory problems for the past two weeks," he said. "I don't know if its from the dust."
"Just the cleaning of the cars is expensive so they should be accountable for something," he added.
The TCEQ tells KENS 5 TCEQ that their offices began receiving calls last Sunday regarding the dust.
The TCEQ also took samples of the air and have not gotten their results. It could take up to 30 days.
