NOTICE OF VIOLATION – Public Notification of Non-Compliance

The South Bossier Water System is currently in violation of the maximum contaminant level (MCL) for total trihalomethanes as set forth by the State {Part XII of Louisiana State Sanitary Code (LAC 51:XII) and the Federal Primary Drinking Water Regulations (40 CFR Part 141).

In December, 1998 EPA set enforceable drinking water standards for TTHMs at 80 parts per billion (ppb) and for HAA5 at 60 parts per billion (ppb) to reduce the risk of cancer or other adverse health effects.  Compliance with the TTHMs and HAA5 standard for public water systems serving less than 10,000 individuals initially became effective and enforceable on January 1, 2004.  Compliance with the TTHMs standard is determined by calculating a locational running annual average (LRAA) of quarterly TTHMs sample results.  Compliance calculations performed for the first quarter of 2021 show that the system’s current TTHMs LRAA exceeded the maximum contaminant level  (MCL) for total trihalomethanes:  Thus the system is currently in violation of the TTHMs standard.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, 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. 

This is not an emergency.  If it had been, you would have been notified immediately.  EPA and LDH do not consider this violation to have any serious adverse health effects on human health as a result of short-term exposure; however, continued long-term exposure to TTHMs and HAA5 levels above the standard (e.g. 20 years of exposure) has the potential to have serious adverse effects on human health.

South Bossier Water System operator is Ken Lott, 318-465-5293 and we are currently working to correct this.
