The cities of Flagstaff and Yuma and the White Mountain Apache Tribe are receiving federal Environmental Protection Agency grants totaling $1.3 million to help clean up a number of "brown fields."

A brownfield is a piece of land on which a hazardous substance, a contaminant or a pollutant is present and needs to be cleaned.

Flagstaff is receiving a $700,000 grant from the EPA to assess the amount of pollution at a number of old gasoline stations along Historic Route 66.

Yuma is using a $400,000 grant to clean up two brownfields.

The White Mountain Apache Tribe is receiving $200,000 to help clean up the site of a lumber mill that operated from 1915 to 1980.

In all, 245 tribes and communities received grants from the EPA to help clean up contaminated sites in 39 states.
