New LABrary at Wenden library lets residents monitor groundwater

The Centennial Public Library in Wenden now gives La Paz County residents a way to check groundwater conditions themselves, with a LABrary built for hands-on monitoring rather than passive display. The Water Alliance of La Paz County says people can check out equipment much like a book, then use it to measure groundwater levels, test water quality, and take part in educational activities tied to the aquifers beneath the county.

The alliance’s public resource hub also puts aquifer basics, maps and data reports, meeting summaries, conservation guidance and downloadable materials in one place. That makes the LABrary more than a library feature. It gives residents a practical accountability tool they can use to compare conditions over time, bring evidence into water-use debates and understand the claims made about local supplies.

That matters in Wenden, Salome, Parker, Quartzsite and nearby communities, where groundwater is the daily supply for homes, farms and businesses. Arizona Department of Environmental Quality highlighted the LABrary in a reel and called it its first-of-a-kind program for community environmental science engagement. ADEQ said the concept lets communities use professional-grade equipment to explore local environmental issues and contribute meaningful data. It also said additional LABraries funded by Arizona State University’s Arizona Water Innovation Initiative will open in Flagstaff and La Paz County, while ADEQ will fund three more in Payson, the White Mountains and along the Colorado River.

The local stakes are sharpened by the Ranegras Plain Groundwater Basin, which the Arizona Department of Water Resources says covers 912 square miles in La Paz County and had an estimated population of 1,259 in its 2024 factsheet. ADWR says the basin has a cone of depression southwest of Vicksburg caused by irrigation wells. On Jan. 9, 2026, the agency designated the basin as a subsequent Active Management Area after first identifying significant groundwater declines at a Governor’s Water Policy Council meeting on Aug. 17, 2023. On March 5, 2026, ADWR proposed a draft management goal to reduce groundwater overdraft by 50% in 50 years.

The county’s broader water history shows why that kind of public monitoring matters. ADWR says the McMullen Valley land subsidence feature includes Wenden, Salome and Aguila, and older basin work found water-level declines in 82 of 94 wells measured between 1994 and 2004. Arizona’s Groundwater Management Code, passed in 1980 and later cited by the Ford Foundation in 1986 as one of the 10 most innovative programs in state and local government, set the framework for the stricter conservation rules now shaping those decisions.

For La Paz County, the LABrary gives residents their own measurements, their own maps and a clearer way to test how water decisions match the conditions on the ground. In a county where aquifers shape housing, agriculture and local business, that access to evidence could change how public water debates are argued and verified.
