Public Notice - Water Violation

The Lavaca Water Department is a public water system which purchases treated water from the Franklin Sebastian Public Water Authority, which purchases treated water from the City of Fort Smith, all being subject to regulations under the federal Safe Drinking Water Act. Those regulations require the notification of customers whenever a violation occurs, and is the basis for this notice.

The contact time (CT) criteria (flow rate, chlorine level, and pH) necessary to meet a 3 log (99.9%) removal/inactivation of Giardia cysts and a 4 log (99.99%) removal/inactivation of enteric viruses was not met during the period of August 14, 2017, from 10:00 p.m. through August 15, 2017, at 10:00 a.m.

Water supplied by the City of Fort Smith water system is from a surface water source. Water from these sources must be treated at prescribed levels prior to entering the distribution system to ensure that certain harmful microorganisms, if present, are not viable. The US Environmental Protection Agency (EPA) sets national drinking water standards and has determined that the presence of microbiological contaminates are a health concern at certain levels of exposure.

If water is inadequately treated, microbiological contaminants in the water may cause disease. These organisms include bacteria, viruses, and parasites which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.

These symptoms, however, are not just associated with disease causing organisms in drinking water, but also may be caused by a number of factors other than your drinking water. EPA has set enforceable requirements for treating drinking water to reduce the risk of these adverse health effects. Treatment such as proper filtering and disinfecting of the water removes or destroys microbiological contaminants. Drinking water which is treated to meet EPA requirements is associated with little to none of the risk and should be considered safe. Failure to meet this requirement does not necessarily mean that the water is unsafe or that alternate sources of water should be used.

According to the City of Fort Smith and the Arkansas Department of Health, pH at the Lee Creek Water Treatment Plant exceeded 9 at 10:00 a.m. on August 14, 2017, and was brought back below pH 9 early in the morning of August 15, 2017. The cause was determined to be rainfall that exceeded 2” in 8 hours. The USEPA and Arkansas Department of Health has set the upper limit pH of 9, and any time the pH exceeds this limit a CT criteria treatment technique violation is issued. Bacteriological testing of the finished water at the Lee Creek Water Treatment Plant taken during the entire month of August 2017 before water was sent to the distribution system showed no presence of total coliform or E. coli.

The Fort Smith Water Utility informs us that they have returned to compliance and as a corrective and preventative measure, have adjusted the pH warning set point to a lower pH level. This will allow treatment plant operators additional time to respond to future pH spikes and prevent the pH from reaching the pH 9 limit.
