Its an update to an issue that's been going on for quite sometime.

On Monday the office of Congressman Henry Cuellar, announced that a large portion of contaminated soil at the former Anzon site, has been cleaned.

The site is now being redeveloped into a sewer treatment plant.

At one time the largest antimony smelter in the world, the former Anzon site was originally located in Mexico.

It moved to Laredo in response to a duty placed on foreign antimony in the 1920s.

According to city officials, the city has reached the final stage of authorizing the purchase of the northern portion and will finalize it soon.
