Is my water safe?
We are pleased to
present
this
year's Annual Water Quality
Report (Consumer Confidence Report) as
required
by the Safe Drinking
Water Act (SDWA).
This report is
designed to
provide details about
where your water comes from, what
it contains, and
how it compares
to standards
set by regulatory agencies.
This report is a snapshot
of last year's
water quality.
We
are committed to providing
you with information because informed customers are our best allies.
Do I need to take special
precautions?
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/Centers
for
Disease Control (CDC) guidelines
on appropriate means
to lessen
the
risk of infection by Cryptosporidium and
other microbial contaminants
are
available from
the
Safe Water Drinking Hotline (800-426-4791).
Where does our water come from?
Your Quality Drinking Water comes
from three very deep
ground
water wells.
All three wells draw from the Hueco
Bolson.
Source water assessment and its availability
If you would like to
know more about source water assessment,
please contact
the
New Mexico drinking
water Bureau
at
(505) 476-8620 or toll free 1-877-654-8720
Why are there contaminants in
my drinking water?
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. More information
about contaminants and
potential
health
effects
can
be obtained
by calling the Environmental Protection Agency's
(EPA) Safe Drinking
Water Hotline (800-426-4791). 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 the 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: microbial
contaminants,
such as viruses
and bacteria, that 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;
and radioactive contaminants,
which can
be
naturally occurring
or be the result
of oil and gas production and mining activities. In order to ensure that tap water is
safe to drink,
EPA prescribes regulations that limit
the
amount of certain contaminants in
water provided
by public water systems. Food and
Drug Administration (FDA) regulations establish
limits for contaminants in
bottled water which must
provide the same protection
for
public health.
How can I get involved?
The Lower Rio
Grande PWWA Board of Directors meet every third Wednesday at
9:00am, locations
are
posted on our website.
Description of Water Treatment Process
Your water is
treated
by disinfection. Disinfection involves
the
addition of chlorine or other
disinfectant to
kill dangerous bacteria and microorganisms
that
may
be in
the
water. Disinfection is considered
to be one of the major public health advances of the 20th century.
Water Conservation Tips
Did you know that
the
average U.S.
household uses approximately 400 gallons
of water per day or 100
gallons
per
person per day? Luckily,
there are many low-cost and
no-cost
ways to conserve water. Small
changes
can make a big difference - try
one today and
soon it will become second nature.
• Take short
showers - a 5 minute shower uses
4 to
5 gallons of water compared to
up to 50 gallons for a bath.
• Shut off water while brushing your
teeth, washing your hair and shaving
and
save up to
500
gallons
a month.
• Use a water-efficient showerhead.
They're inexpensive,
easy to install, and
can save you up to 750 gallons a
month.
• Run your clothes
washer and dishwasher only
when they are full. You
can save up to
1,000
gallons
a month.
• Water plants only
when necessary.
• Fix leaky
toilets
and faucets. Faucet
washers are inexpensive and take only a few
minutes to
replace. To
check your toilet for a leak,
place a few
drops of food coloring in
the
tank and wait. If it
seeps into the toilet bowl
without
flushing, you have a leak. Fixing it
or replacing it
with
a new, more efficient
model
can
save up to 1,000 gallons
a month.
• Adjust sprinklers
so only your lawn is
watered. Apply water only
as fast as the soil
can absorb it and
during
the
cooler parts of the day
to reduce evaporation.
• Teach your kids about
water conservation to
ensure a future generation
that
uses water wisely. Make it a
family effort to reduce next
month's water bill!
• Visit www.epa.gov/watersense for more information.
Cross Connection Control
Survey
The purpose of this
survey is
to determine whether a cross-connection may exist
at your home or business. A cross
connection is an unprotected
or improper connection
to a
public water distribution
system
that may cause contamination or
pollution to enter the system. We are
responsible for enforcing cross-connection
control regulations
and insuring
that no contaminants can,
under any flow conditions,
enter the distribution
system. If you have any
of the devices
listed below
please contact
us so that we can discuss
the
issue, and if needed, survey your connection
and
assist you in isolating
it if that is necessary.
• Boiler/
Radiant
heater (water heaters not included)
• Underground
lawn
sprinkler system
• Pool or hot tub
(whirlpool
tubs not included)
• Additional
source(s) of water on the property
• Decorative pond
• Watering trough
Source Water Protection Tips
Protection of
drinking water is everyone's responsibility.
You can help protect
your community's drinking water source in several
ways:
• Eliminate excess
use of lawn and
garden fertilizers
and pesticides - they contain
hazardous chemicals
that
can reach your drinking
water source.
• Pick up after your pets.
• If you have your own septic system,
properly maintain your
system to reduce leaching
to water sources or consider connecting to
a public water system.
• Dispose of chemicals
properly;
take used
motor oil
to a
recycling center.
• Volunteer in
your community. Find a
watershed or wellhead protection
organization
in your community and
volunteer to
help. If there are no
active groups, consider starting
one. Use EPA's
Adopt Your Watershed to
locate groups in
your community, or visit the Watershed Information Network's How
to Start a Watershed Team.
• Organize a storm drain stenciling project
with
your
local government
or water supplier.
Stencil
a message next
to the street drain reminding people "Dump
No Waste - Drains to
River"
or "Protect
Your Water."
Produce and
distribute a flyer for households to
remind
residents
that
storm
drains dump
directly into your
local water body.
Additional Information for Lead
The Lower Rio
Grande PWWA East
Mesa inventory does
not include lead service lines.
We completed the required report
but there were some connections
with
unknown pipe composition.
We
are working on identifying these unknown connections.
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. Lower Rio Grande PWWA East
Mesa is responsible for providing high
quality
drinking water and
removing lead pipes,
but cannot control
the
variety
of materials
used in plumbing
components in
your home. You share the responsibility for protecting yourself and
your family
from the lead in
your home plumbing. You
can take responsibility by identifying
and removing lead materials
within your
home plumbing
and taking steps to
reduce your family’s
risk. Before drinking tap water, flush your
pipes for several
minutes by running your
tap, taking
a shower, doing laundry or a load of dishes.
You
can also use a filter certified by an
American National
Standards Institute accredited
certifier to reduce lead
in drinking water. If you are concerned about
lead
in your water and wish to
have your water tested, contact
Lower Rio Grande
PWWA East Mesa (Public Watersystem Id:
NM3512007) by calling 575-233-3947 or emailing mike.lopez@lrgauthority.org. Information
on lead
in drinking
water, testing
methods, and
steps
you can take to minimize exposure is available at http://www.epa.gov/safewater/lead.
Water Quality Data
Table
In order to ensure that tap
water is safe to drink, EPA prescribes regulations which
limit the amount of contaminants
in water provided by public water systems. The
table below
lists
all of the drinking water contaminants that we detected during the calendar year of this
report.
Although many more contaminants were tested, only those substances
listed below were found
in your water. All
sources of drinking water contain some naturally
occurring contaminants. At
low levels, these substances
are generally not harmful
in our drinking
water. Removing all contaminants would be extremely
expensive, and in
most cases, would
not provide increased protection of
public health.
A few naturally occurring
minerals may actually improve the taste of drinking
water and
have nutritional value at
low levels. Unless
otherwise noted,
the
data
presented
in this table is from
testing done
in the calendar year of the report.
The EPA or the State requires us to
monitor for certain
contaminants less than once per year because
the concentrations of
these contaminants
do not vary significantly
from year to year, or
the system
is not considered vulnerable to
this
type
of contamination. As
such, some of our data,
though representative,
may
be more than
one year old. In this table you will find terms
and abbreviations
that
might not be familiar to you. To help you
better
understand these terms,
we
have provided
the definitions below the table.
