Directors & Districts

Luana Buckner, Chairman

Medina & Atascosa Counties – District 13

Term Expires December 2022

Luana Buckner has likened her history with the EAA to “a tall Texas tale.” Elected to the inaugural board of directors in 1996, the Medina County resident was originally a party in a lawsuit that challenged the creation of the EAA. When the Texas Supreme Court ruled the EAA Act was constitutional, her motto became, ‘If you can’t beat’em, join’em!”

Buckner grew up in a ranching family in Zavala County. Her parents bred registered Black Brangus cattle. As a teenager, she was asked to help brand livestock and administer medication.

After graduating from nearby Uvalde High School, Buckner attended Southwest Texas Junior College. As a reporter, then editor, for the Castroville News Bulletin, Buckner wrote extensively about water-related issues, including the Applewhite Reservoir, a controversial project on the Medina River first rejected by voters in 1991.

In 1992, Buckner became the first general manager of the Medina County Groundwater Conservation District and the first woman general manager of a conservation district in Texas. She retired from the position in 2012.

After the initial two-year EAA board term, Buckner has been re-elected for six consecutive four-year terms, beginning in 1998.  As chair, Buckner presides over the board’s Executive Committee.

Of her long-time service Luana shares the following thought: “I think some people thought I would just be representing the irrigators and the rural communities, and I think they’ve seen that I can see the big picture.”

A real estate investor and a consultant in groundwater issues and natural resource management, Buckner currently lives outside of Castroville.

He went on to earn a juris doctorate degree from the University of Wisconsin. Shortly after graduating, Valdivia moved to Texas to work in immigration law for a non-profit based in Harlingen. He began working for Texas Rio Grande Legal Aid in 1985.

“My practice over the years took on more and more environmental cases,” Valdivia said. “It was something that I started seeing more of a need for, so I pursued that and built it up to where it’s mainly what I do now at Legal Aid.”

He has lived in San Antonio since the mid-1990s. He serves on the boards of the Sierra Club Alamo Group and Texas Fund for Economic & Environmental Education. Re-elected to the EAA board in 2010 and 2014.

Deborah Carington

Bexar County – District 6

Term Expires December 2024

Deborah Carington grew up on a small farm outside of Memphis, where her family relied on well water from the Memphis Sand Aquifer, “so I grew up with the awareness of where our water came from and knowing that it was high quality drinking water,” she said.

In college at the University of Southern Mississippi, Carington intended to major in environmental science, but a geology class changed the course of her studies and her life. After earning a Bachelor of Science, she continued her education at the University of Memphis. While there, Carington worked at the school’s Center for Earthquake Research and Information, monitoring the frequent microearthquakes along the New Madrid Fault.

With a Master of Science in geology, she landed a job with an oil company in Houston in 1982.

In 1998, they moved to San Antonio and Carington took time away from her professional life to raise two children.

Over the course of her career, one of Carington’s largest projects was developing a new Austin Chalk limestone reservoir in East Texas, “so I understand the subsurface geology, well-drilling process, permitting and sustainable withdrawal,” she said.

A realtor and retired computer geologist, Ronald J. Walton has 34 years’ experience working for various federal agencies on water-related issues.

Walton grew up on a small farm in Indiana where his parents raised cattle and hogs and grew corn and soybeans. Much like the Edwards Aquifer region, the topography of the surrounding area featured limestone deposits, sinkholes, caves and underground rivers. His interest in hydrogeology was sparked by the exploration geologists who frequently visited the farm.

After graduating from Indiana University Bloomington with a Bachelor of Science in 1961, Walton intended to go to the U.S. Navy’s Officer Candidate School. Before Walton could to be sworn in, he was offered a job as a geological oceanographer with the U.S. National Oceanographic Data Center in Washington, D.C. At the time, private industry jobs were scarce, so he “jumped at the opportunity.”

Next, he went to work for the Army Corps of Engineers. Walton’s first job with the federal agency was running the Great Lakes Regional Data Center in Detroit. He then transferred to the U.S. Coastal Engineering Center in D.C. where he oversaw beach erosion studies around the country. During this time, he earned a master’s degree from American University. Most recently, he worked for the U.S. Geological Survey in Denver.

Walton and his wife Judith have been married for 55 years.

Yanta’s son Cole, a student at Texas A&M University, and daughter Kaylee, who has been accepted to A&M, both plan to return to the farm when they complete their educations.

“We’ve got to have this water to make a living,” Yanta said. “We’ve got to make it last for the next generation to come.”

“I never saw myself as an environmentalist and still don’t,” he said. “But the necessity to maintain all those critters at the springs certainly is a driving force for us having water in Victoria. You can’t have one without the other.”
