PLEASANTON -- A study of the Carrizo-Wilcox Aquifer area in Wilson County took center stage at the Jan. 31 meeting of the Evergreen Underground Water Conservation District board.
The board of directors and members of the public met at the district’s Pleasanton office primarily to hear petroleum geologist Richard Hargis of San Antonio report on his study, which he started in 2008.
Displaying graphs, charts, maps, and cross-sectional representations of what lies below the surface of the earth down to hundreds of feet, Hargis illustrated his report via computer projections on the wall of the meeting room. His study began with his examination and correlation of the electronic logs for 605 wells in Wilson County. He later added 62 more wells in Wilson County and in small adjoining sections of Bexar and Guadalupe counties.
The study looked at the 10 major shale formations and the seven fault lines in Wilson County.
“These are what we call nominal faults,” he said. “I haven’t seen any evidence of water movement up the faults.”
The study recorded not only the contours of the surface, but also the thickness of the various substrata.
Evergreen Director Jay Troell said he thought the value of the study was for landowners working with a geologist or a hydrologist to determine where they can best drill a well.
“This is the best study ever made [of the area], both in quality and in volume,” Troell said, adding that people with a background in geology will find it easier to understand.
The entire study will be available to the public, according to district General Manager Russell Labus, who noted that the Carrizo [Aquifer] served most of Wilson County.
“Ninety percent of the wells [in Wilson County] draw from Carrizo Springs,” he said. “It’s good water.”
Labus said the Carrizo is closer to the surface in most of Wilson County, but Gulf Coast water was closer to the surface in southern parts of the county.
“The farther south you go, the saltier the water,” Labus said.
During the public comments, citizen Bob Ulrich praised the study but took issue with being asked to leave a meeting that was held the previous day.
“Your job is to be open and transparent,” Ulrich said. “The meeting should be posted, even if it’s a committee meeting.”
“That’s not going to happen,” responded board president Steve Snider. “The meetings prior to the board meeting are to discuss what we’ll be doing at the board meeting.”
Board members also discussed an article in another newspaper that seemed to imply that board members Troell and Larry Fox were speaking for the entire board. Both Troell and Fox said they sent a letter to the newspaper clarifying that the opinions they expressed were their own and not the district’s. Board member Diane Savage said any official statement emanating from the Evergreen board should have the signature of the board president or the general manager.
Elsewhere on the agenda, the board voted to approve seven uncontested water well drilling and production permits.
In addition to Snider, Troell, Fox, and Savage, board members Blaine Scharp (secretary/treasurer), Clifton Stacy (vice president), Craig Nieschwietz, and Jason Peeler attended.
