BAKERSFIELD, Calif. -- At the beginning of November, Eyewitness News reported that families of local railworkers were upset because BNSF Railroad wanted to move around 100 workers from Bakersfield to Barstow.

Now they're saying there's another reason to stay put.

Residents in San Bernadino County were warned late last week not to drink the tap water after Barstow's water supply was found to have traces of a toxic chemical that's used to make rocket fuel and explosives.

Residents were told boiling the water would not help in reducing the chemical level in the water. Instead, residents were urged to take advantage of the free water bottles that were being distributed around the area.

Governor Arnold Schwarzenegger declared a state of emergency for the county after the contaminated tap water was found.

On Sunday, officials have lifted restrictions drinking water for about half of Barstow's residents.

As for the railworkers and their families they said the contaminated water is one more reason to not be transferred.

The railroad's plan is to move workers from Bakersfield, Los Angeles and Needles toits Barstow operation.

There's no definite timeline on when the transfer will happen.
