Central Texas Water Supply Corporation-Violation

Mandatory Language for Surface Water Treatment Technique Violation

SURFACE WATER TREATMENT TECHNIQUE: [NON-ACUTE]

The Texas Commission on Environmental Quality (TCEQ) sets minimum water quality standards for public drinking water. These standards include enforceable treatment technique requirements for drinking water. Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.

The Central Texas Water Supply Corporation, PWS ID TX# 0140161, failed to meet the minimum treatment technique requirements for the month of October 2018. Specifically, our water system had: Combined filter effluent turbidity readings above 1.0 NTU, and more than 5% of the combined filter effluent turbidity readings were above 0.3 NTU for the month.

Central Texas Water Supply Corporation has taken the following corrective actions to prevent a recurrence of the violations: Violations occurred during severe flood conditions causing 700-6000 NTU's. Plant #1 was problematic and was shut down to prevent further issues. Plant #2 was used for water treatment as it is better able to handle flood conditions. Eastern customers were switched to treated water from the Doc Curb Water Treatment Plant. This allowed us to slow down Plant #2 and investigate and correct problems with Plant #1.

Please share this information with all people who drink this water, especially those who may not have received this notice directly (i.e., people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.

If you have questions regarding this matter, you may contact Lee Kelley, General Manager, 254-698-2779, at Central Texas Water Supply Corporation.
