The Texas Commission on Environmental Quality rescinded its nitrate violation notice against Wellborn Special Utility District after a water sample near the Harlan Road Surface Water Treatment Plant measured 10.4 mg/L, above the 10 mg/L limit. The regulator said the district is in compliance with nitrate drinking water requirements and authorized it to withdraw the original public notice issued November 9, 2026.
Why it matters
The reversal means Wellborn customers were initially told of a nitrate exceedance that regulators later determined was not a regulatory violation. Nitrate above the maximum contaminant level can pose health risks for infants and pregnant women, which is why the district offered bottled water to those customers.
The figure comes from a single water sample near the Harlan Road plant, measured at 10.4 mg/L against a 10 mg/L nitrate limit. Whether the Harlan Road source returns to service remains unknown until the additional samples are analyzed.
The players
Wellborn Special Utility District
A public water utility serving customers in the Wellborn area of Texas that issued the original nitrate notice and later the update.
Texas Commission on Environmental Quality
The state agency that regulates public drinking water systems in Texas and rescinded the nitrate violation notice.
The details
Wellborn Special Utility District issued a public notice on November 9, 2026, at the direction of the Texas Commission on Environmental Quality after the sample exceeded the nitrate limit. On November 10, the regulator notified the district its initial determination was incorrect, clarified the result does not constitute a regulatory violation, and authorized the district to withdraw the notice. The district took the Harlan Road water source offline as a precaution and is collecting additional samples.
Timeline
November 9, 2026: Wellborn SUD issues public notice on the nitrate sample.
November 10, 2026: TCEQ rescinds the violation and the district issues an update release.
Seasonal Patterns
The 10 mg/L nitrate maximum contaminant level under the Safe Drinking Water Act sets the threshold this sample was measured against. The regulator's reversal shows a single exceedance can be reclassified on review rather than treated as a confirmed violation.
Customers with infants under six months or who are pregnant can request bottled drinking water from Wellborn Special Utility District. Residents can review the district's update for the latest status on the affected water source.
The takeaway
A single sample exceedance can be reclassified on regulatory review, so residents should watch for official updates before changing their water use. Customers in higher-risk groups should keep bottled water available until the district confirms the source's status.
What happens next
Additional samples collected by Wellborn SUD will determine whether the Harlan Road Surface Water Treatment Plant source returns to service.
