Dear Customer,

The Vermilion Waterworks District #1 is currently in violation of the maximum contaminant level (MCL) for total trihalomethanes as set forth by the State (Part XII of the Louisiana State Sanitary Code (LAC 51: XII) and the Federal Primary Drinking Water Regulations (40 CFR Part 141)

The United States Environmental Protection Agency (EPA) and the Louisiana Department of Health

(LDH) set drinking water standards and requires the disinfection of drinking water. Where disinfection

is used in the treatment of drinking water, disinfectants combine with naturally occurring organic and

inorganic matter present in water to form chemicals called disinfection byproducts (DBPs). EPA and

LDH set standards for controlling the levels of disinfectants and DBPs in drinking water, including trihalomethanes (THMs) and haloacetic acid (HAAs). Some people who drink water containing THMs

in excess of the MCL over many years may experience problems with their liver, kidneys, or central

nervous system and may have an increased risk of getting cancer.

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 TTHM’s 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 TTHM’s standard is determined by calculating a locational running annual average (LRAA) of

quarterly TTHMs sample results. Compliance calculations performed for the third quarter of 2026

show that the system’s current TTHM’s LRAA is 83 ppb at DBP06-BERNELL @ HWY 91: 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 business). 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.

Should you need additional information concerning this notice, please feel free to contact Mr. Jerome Meaux,

System Manager, Waterworks District No. 1 at 337-898-8345. Our physical mailing address is 11822 La Hwy 699, Maurice, La 70555, as you are welcome to contact us either in person or by mail.

Thank you,

Waterworks District No. 1
