Rural residents press Nueces County court to back proposed groundwater district amid concerns over large-scale pumping

Trey Cranford, speaking for organizers of the proposed Nueces Groundwater Conservation District, told the Nueces County Commissioners Court on Feb. 25 that withdrawals planned by the City of Corpus Christi and other projects already exceed the county's modeled available groundwater (MAG) and risk long-term harm to rural wells and water quality.

"Currently the municipal pumping alone exceeds MAG levels," Cranford said, citing a MAG of 6,787 acre-feet and warning that municipal plans for well fields could total 43,000,000 gallons per day. He added that combined planned withdrawals in a roughly 15-mile radius could reach 75 million to 110 million gallons per day — many times the MAG.

Why it matters: Petitioners said the county has no local groundwater regulator and that without a Groundwater Conservation District (GCD) heavy-volume users operate under the rule of capture. Kelly Harland, the lead petitioner for the proposed district, said groundwater declines have already affected water quality and supply. "When groundwater levels drop, wells decline, pump strain, cost rise, and water quality changes," Harland told the court, and she asked the commissioners for an official resolution supporting stronger local oversight to protect rural residents.

Testimony from rural residents described immediate impacts. One rancher said his static water level fell about 15 feet in six months after nearby municipal pumping began and warned that higher TDS levels and changing chemistry could harm livestock on working farms.

Cranford described the statutory and administrative pathway to form a GCD: an application review by the Texas Commission on Environmental Quality (TCEQ), a TCEQ public hearing, and — if administratively complete — a November ballot in which county voters would confirm the district, elect its board and determine funding (production fee, ad valorem tax, or both). He emphasized that GCDs operate under Texas Water Code chapter 36 and are the state's preferred method for managing groundwater.

The presentation also raised water-quality concerns. Cranford pointed to test results for one municipal well (Well 13) showing high TDS and detections of arsenic and uranium, and said the organizers had documented arsenic detections at WCID No. 3 that supply Robstown. He said the organizing committee plans independent monitoring wells and baseline measurements to support any future mitigation claims: "As an organizing committee, we're taking money, and we will also be doing some monitoring wells," Cranford said.

Commissioners' response was mixed. Several said the court lacks legal authority to regulate activities inside Corpus Christi, and cautioned against taking sides in a dispute where the city and petitioners disagree. Others said a symbolic county resolution or public support could help rural constituents and influence state review. One commissioner urged the city be invited to explain its monitoring and mitigation plans; Cranford said he had requested a written mitigation plan and that the petitioners had asked for more coordination.

No formal action was taken; the item was presented as information and plaintiffs asked for the court's support going forward. Cranford closed by urging residents to submit public comment during the TCEQ petition review and asking the court to encourage coordination with the county's legislative delegation and TCEQ.

Next steps: The TCEQ review was under way at the time of the meeting; if TCEQ deems the application administratively complete, the organizing group hopes to reach a November ballot for voter confirmation. The organizers said they would continue outreach to commissioners and pursue monitoring and independent hydrogeologic review to document impacts.
