We are pleased to present to you
the Annual Water Quality Report for the year 2014. This report is designed to
inform you about the quality of your water and services we deliver to you every
day (Este informe contiene información muy importante sobre su agua potable.
Tradúzcalo o hable con alguien que lo entienda bien). Our constant goal is to
provide you with a safe and dependable supply of drinking water. We want you to
understand the efforts we make to continually improve the water treatment
process and protect our water resources. We are committed to ensuring the
quality of your water.
Our water source(s) are listed

The sources of drinking water
(both tap water and bottled water) include rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As water travels over the surface of land or
through the ground, it dissolves naturally-occurring minerals and, in some
cases, radioactive material, and can pick up substances resulting from the
presence of animals or from human activity. Contaminants that may be present in
source water include:
Microbial Contaminants - such as
viruses and bacteria, which may come from sewage treatment plants, septic
systems, agricultural livestock operations, and wildlife.
Inorganic Contaminants - such as salts
and metals, which can be naturally-occurring or result from urban stormwater
runoff, industrial, or domestic wastewater discharges, oil and gas production,
mining, or farming.
Pesticides and Herbicides - which may come
from a variety of sources such as agriculture, urban stormwater runoff, and
residential uses.
Organic Chemical Contaminants – including
synthetic and volatile organic chemicals, which are by-products of industrial
processes and petroleum production, and can also come from gas stations, urban
stormwater runoff, and septic systems.
Radioactive Contaminants – which can be
naturally-occurring or be the result of oil and gas production and mining
activities.
A Source Water Assessment Plan
(SWAP) is now available from our office. This plan is an assessment of a
delineated area around our listed sources through which contaminants, if
present, could migrate and reach our source water. It also includes an
inventory of potential sources of contamination within the delineated area, and
a determination of the water supply's susceptibility to contamination by the
identified potential sources. According to the Source Water Assessment Plan,
our water system had a susceptibility rating of 'MEDIUM'. If you would like to
review the Source Water Assessment Plan, please feel free to contact our office
at the number provided in the following paragraph.
In order to ensure that tap
water is safe to drink, EPA prescribes regulations which limit the amount of
certain contaminants in water provided by public water systems. Food and Drug
Administration regulations establish limits for contaminants in bottled water
which must provide the same protection for public health. We are pleased to report that our drinking water is safe and meets
Federal and State requirements. If you have any questions about this
report, please contact John D. Nichols, Operations Manager, or Wayne E. Allen,
Board President, at (318) 322-9516 or any of your other water system board
members. We want our valued customers to be informed about their water utility.
If you want to learn more, please attend any of the regularly scheduled
meetings. The Board of Directors of Cheniere Drew Water System conducts a
monthly business meeting on the second Tuesday of each month at 7 PM. The
location of this business meeting is at the water office located at 646
Commercial Parkway in West Monroe.
If present, elevated levels of
lead can cause serious health problems, especially for pregnant women and young
children. Lead in drinking water is primarily from materials and components
associated with service lines and home plumbing. CHENIERE DREW SOUTH WATER
SUPPLY is responsible for providing high quality drinking water, but cannot
control the variety of materials used in plumbing components. When your water
has been sitting for several hours, you can minimize the potential for lead
exposure by flushing your tap for 30 seconds to 2 minutes before using water
for drinking or cooking. If you are concerned about lead in your water, you may
wish to have your water tested. Information on lead in drinking water, testing
methods, and steps you can take to minimize exposure is available from the Safe
Drinking Water Hotline or at http://www.epa.gov/safewater/lead.
The Louisiana Department of
Health and Hospitals - Office of Public Health routinely monitors for constituents
in your drinking water according to Federal and State laws. The tables that
follow show the results of our monitoring during the period of January 1st to
December 31st, 2014. Drinking water, including bottled water, may reasonably be
expected to contain at least small amounts of some contaminants. The presence
of contaminants does not necessarily indicate that water poses a health risk.
In the tables below, you
will find many terms and abbreviations you might not be familiar with. To help you better understand these terms,
we’ve provided the following definitions:
Parts per million (ppm) or Milligrams per liter (mg/L) – one part per
million corresponds to one minute in two years or a single penny in $10,000.
Parts per billion (ppb) or Micrograms per liter (ug/L) – one part per
billion corresponds to one minute in 2,000 years, or a single penny in
$10,000,000.
Picocuries per liter (pCi/L) – picocuries per liter is a
measure of the radioactivity in water.
Nephelometric Turbidity Unit (NTU) – nephelometric
turbidity unit is a measure of the clarity of water. Turbidity in excess of 5
NTU is just noticeable to the average person.
Action level (AL) – the concentration of a contaminant
that, if exceeded, triggers treatment or other requirements that a water system
must follow.
Maximum contaminant level (MCL) – the “Maximum Allowed” MCL is the
highest level of a contaminant that is allowed in drinking water. MCL’s are set as close to the MCLG’s as
feasible using the best available treatment technology.
Maximum contaminant level goal (MCLG) – the “Goal” is
the level of a contaminant in drinking water below which there is no known or
expected risk to human health. MCLG’s
allow for a margin of safety.
Maximum residual disinfectant level (MRDL) – The highest
level of a disinfectant allowed in drinking water. There is convincing evidence
that addition of a disinfectant is necessary for control of microbial
contaminants.
Maximum residual disinfectant level goal (MRDLG) – The level of a
drinking water disinfectant below which there is no known or expected risk to
health. MRDLGs do not reflect the benefits of the use of disinfectants to
control microbial contaminants.
During the period covered by
this report we had below noted violations of drinking water regulations.

++++++++++++++Environmental
Protection Agency Required Health Effects Language++++++++++++++++
Some
people may be more vulnerable to contaminants in drinking water than the
general population. Immuno-compromised persons such as persons with cancer
undergoing chemotherapy, persons who have undergone organ transplants, people
with HIV/AIDS or other immune system disorders, some elderly, and infants can
be particularly at risk from infections. These people should seek advice about
drinking water from their health care providers. EPA/CDC guidelines on
appropriate means to lessen the risk of infection by Cryptosporidium and other
microbial contaminants are available from the Safe Drinking Water Hotline
(800–426–4791).
Additional Required Health Effects Language:
Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present. Coliforms were found in more samples than allowed and this was a warning of potential problems.
95th Percentile Health Effects Language
Infants and children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing. If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (800-426-4761).
There are no additional required health effects violation notices.
