Story highlights Some people can now drink, cook and bathe with the water, city says

Other residents advised to avoid tap water until further notice

An incident in the city's industrial district may have contaminated water supply

(CNN) Water-use restrictions imposed because of possible water supply contamination have been lifted for some residents of Corpus Christi, Texas, city officials said Friday.

Those residents may again use the water to drink, cook, bathe and for "all regular uses," the city said.

But restrictions are still in place in other parts of the city of 300,000 people.

In one zone, people are urged to not use the city water at all. They should use only bottled water, the city said in an advisory issued Friday.

In a second zone, residents can safely bathe and wash clothes but should not drink the water or cook with it, the advisory said. Children should not be bathed with water in the second zone because they might accidentally consume some of it.
