Notice of Surface Water Treatment Technique Violation
(A one-time, single day occurrence)
The Brazos Regional Public Utility Agency (BRPUA) owns and operates the Lake Granbury Surface Water and Treatment (SWATS) plant that regionally provides safe drinking water to Acton Municipal Utility District, City of Granbury and Johnson County Special Utility District. On November 13, 2015, there was a single occurrence in sample testing that failed to meet the minimum treatment technique requirements. Specifically, the level of “turbidity” exceeded the regulated maximum allowable for the filtered water of 1.0 NTU (Nephelometric Turbidity Units) which prompts the need to issue this Notice. However, at no time was the health of the public put at risk.
Turbidity is the measure of the clarity of water after treatment is applied to make safe drinking water. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
The spike in turbidity measured was a matter of non-compliance. However, turbidity levels in the finished drinking water leaving the facility met all State Drinking Water Standards, and at no time was the health of the public put at risk.
The BRPUA has taken proper action to ensure that this situation does not re-occur.
