            LIBBY WSC - PWS lOt 1740012
            NACOGDOCHES County, Texas

Our record review shows that the LIBBY WSC water system violated the maximum contaminant level (MCl) for trihalomethanes
(TTHM) in the water supplied to Its customers. This violation occurred during the second quarter of 2009. 30 TAC, Chapter
§290.113, of the Texas Administrative Code describes how we determined that this violation occurred.

The information that we used to determine compliance for your system is shown in the table below. The MCl for TTHM is 0.080
milligrams per liter (mgll) (80 micrograms per liter (~gIl» based on a running annual average. Based on the data contained in the
table below, we determined that the running annual average of TTHM was 0.084 mgll (84 ~gIl).

    The LIBBY WSC has been notified by the Texas Commission on Environmental Quality (TCEQ) that the water            '
    this system supplies has exceeded the maximum contaminant level (MCl) for total trihalomethanes (TTHM's),
    as set in the Commission's Drinking Water Standards.

    The MCl for TTHM's is 0.080 milligrams per liter (mg/L). Compliance with this level is based on a running
    annual average of quarterly sample results. The LIBBY WSC's running annual average for quarter 2 of 2009
    was 0.084 mg/L.

    Trih~lomethanes are a group of volatile organic compounds that are formed when chlorine, added to the water
    during the treatment process for disinfection, reacts with naturally-occurring organiC matter in the water.

    Some people who drink water containing trihalomethanes in excess of the MCl over many years may
    experience problems with their liver, kidney. or central nervous systems, and may have an increased risk of
    getting cancer.

    You do not need to use an alternative water supply. However, if you have health concerns, you may want to
    talk to your doctor to get more information about how this may affect you.

    We are working to correct the problem. (A).

    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.

    If you have any questions concerning this notice, you may contact _ _ _ _ _ _(B),______ at
