Etna Borough (pop of 3,426) is a demographically diverse community along the Allegheny River just outside of Pittsburgh in Allegheny County. It is an old steel mill town, named after the volcano Mount Etna, an allusion to blast furnaces, steel mills, galvanized-pipe works, and other manufacturers once located there. It now has a mix of many long-time residents who were raised in the community and a recent large influx of younger, ethnically diverse residents who have been attracted to the community for their focus on the environment, their green practices and on the values of EcoDistrict work.
