TUCSON, Ariz. (AP) — Many families in Arizona mining communities have concerns about what pollutants might be in their immediate environment and in harvested rainwater for gardens.

The Arizona Daily Star reports a University of Arizona program is underway to help communities such as the mining and industrial towns of Hayden-Winkelman, Globe-Miami and Dewey-Humboldt and also on Tucson's south side, reaching about 160 households.
