(New Mexico News Connection) Federal funding for infrastructure improvements in colonias, predominately rural, Hispanic communities near the U.S.-Mexico border, including 150 in New Mexico, is getting a second look from the U.S. Government Accountability Office.

Jill Naamane, financial markets and community investment director for the GAO, said there are grant and loan programs targeting colonias to improve water and wastewater systems and housing but the U.S. Department of Agriculture does not have accurate data on the extent of program benefits.

She pointed out colonias have high poverty rates.

"Many of them started as settlements that were associated with military forts or missionary activities, so they kind of grew up outside of cities without being connected to the same infrastructure," Naamane explained.

The GAO analyzed program documentation and funding data from 2020 to 2023, conducted local interviews and made physical observations during 24 site visits in the four U.S.-Mexico border states. They recommended Congress consider revising the population requirement for colonias to continue receiving block-grant funding given population growth in the Southwest.

Naamane acknowledged many colonias face challenges in obtaining and using federal assistance because local governments do not have the staff to apply for federal funds. Without some administrative revisions, she projects nearly 60 percent of colonias will likely become ineligible in the future for certain targeted financial assistance.

"They're typically areas that have poor water and sewage infrastructure, substandard housing and a number of other economic and environmental challenges," Naamane outlined. "There's a continuing need for assistance in these communities."

In southern New Mexico, the designated colonia of Anthony, home to about 10,000 people, is refurbishing and expanding its wastewater treatment plant with grants and loans from the USDA. The new plant started treating wastewater this month, with the entire project scheduled for completion in November.
