Environmental Protection at Arizona’s Border

ORBA focuses on cross-border issues that impact Arizona’s environment and citizens. We work in a binational and bicultural setting to promote efforts aimed at improving air quality, waste management and water quality conditions within Arizona’s border communities.

ORBA regularly meets with the Arizona-Mexico Commission (AMC) to develop action plans for projects or activities done in collaboration with the State of Sonora. Progress on action plans are reported to the AMC.

We also work with U.S. Environmental Protection Agency (EPA) through its U.S./Mexico Border 2020 Program, which includes a regional workgroup addressing environmental issues spanning both sides of the border | Learn More >

Arizona Border Trash

The Arizona Border Trash website, azbordertrash.gov, is no longer online due to the limited number of cleanups documented since 2019 by groups conducting them. For historical files and/or data from this website please make a public records request | Learn How >
