U.S. Rep. Raúl Grijalva (D-AZ) released a statement on Tuesday commending the Environmental Protection Agency’s awarding of over $15 million in grant funding for environmental improvements to the tribal lands of several indigenous tribal communities in Arizona.

Grant recipients include the Havasupai Tribe, Tohono O’odham Nation and Gila River Indian Community.

“Respect for the planet is part and parcel to daily life for native tribes, and I’m glad that EPA recognizes their tremendous contributions to conservation in Arizona,” Grijalva said. “The funds announced today will support water-quality projects, watershed protection and restoration, water-energy efficiency, wastewater reclamation and vital drinking-water infrastructure.

“At the same time, the funds provide critical economic support, allowing tribes to build the capacity to carry out environmental work,” Grijalva said. “I’m thrilled to see such a worthwhile investment and look forward to partnering with EPA and native tribes in the future to protect Arizona’s lands and waterways.”
