LEAD AND COPPER IN DRINKING WATER
Municipal drinking water is a unique
product — it is the only life-sustaining
resource reliably delivered by others
to your home around the clock for
your convenient use on demand.
This requires special infrastructure
including a valuable, extensive and
relatively expensive piping network.
Elements of this network, especially
residential plumbing systems, contain
lead. While the plumbing industry
has reduced the lead level in these
elements, it has not yet entirely
eliminated it. Homes built prior to
1986 are more likely to have plumbing
materials with greater lead levels, but
newer homes are also at risk.
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. The Liberty Utilities Department 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 two 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 (800.426.4791) or at http://water.epa.gov/drink/info/lead/index.cfm
Contact Kevin Ash of the Liberty Utilities Department Water Division at 816.439.4571 for additional guidance.
You can also find sample results for all contaminants from both past and present compliance monitoring online
at the Missouri DNR Drinking Water Watch website www.dnr.mo.gov/DWW. To find Lead and Copper results
follow these steps:
• Type “Liberty PWS” or “Kansas City PWS” in the box titled Water System Name and select Find Water
Systems at the bottom of the page
• The new screen will show you the water system name and number (Liberty: MO-1010466; Kansas City:
MO-101415). Click the Water System Number.
• At the top of the next page, under the Help column, click on Other Chemical Results by Analyte.
• Scroll down alphabetically to Lead and click the blue Analyte Code (1030). A sample collection date range
may need to be entered.
• The Lead and Copper locations will be displayed under the heading Sample Comments. Scroll to find your
location and click on the Sample No. for the results.
If you assisted the Utilities Department in taking a Lead and Copper sample from your home but cannot find
your location in the list, please contact the Liberty Utilities Department Water Division for your results.

IF IT’S ON THE GROUND - IT’S IN OUR WATER
Storm drains are the metal grates found on urban
and suburban streets, often at corners and on
the sides of curbs and gutters. They help prevent
flooding by draining rainwater and melted snow
off of streets and other paved surfaces.
While storm drains were designed to divert
water from streets, they can become dangerous
water polluters when harmful substances from
lawns and streets flow through them. During a
rainfall, water runs down streets and through
yards, picking up substances along the way. This
“runoff ” often contains elements that pollute our
waterways, can harm wildlife, and degrade water
quality.
Water that enters storm drains is not cleaned at a wastewater treatment plant before it flows directly to
streams, rivers and lakes. Some common contaminants in stormwater include lawn chemicals, pet waste,
household chemicals like paint and soaps used for washing cars.
Is a Storm Drain System the same thing as a Sanitary Sewer System?
Sewer systems and storm drain systems are not the same. The water that goes down a sink or toilet in your
home or business flows through a sanitary sewer system to the wastewater treatment plant where it is
treated and cleaned. Water that flows down a driveway or street and into a gutter goes into a storm drain
which goes directly to a natural body of water, untreated.
How can I help?
There are several simple actions you can take that can save time, resources and money — all while
protecting the health of residents, communities and the environment.
• Pick up after your pet. Pet waste is not a fertilizer – it contains harmful bacteria. Carry disposable
bags while walking your dog to pick up and dispose of waste properly.
• Use lawn chemicals sparingly. Chemical fertilizers, pesticides and herbicides can contain
ingredients harmful to human health and the environment. Improper application of these substances
causes them to run off lawns and down storm drains.
• Go natural. Instead of using chemical products, consider compost or natural lawn-chemical
alternatives.
• Landscape with native plants and rain gardens. Native plants have natural properties that often
eliminate or reduce the need for mowing, fertilizing or using pesticides. Rain gardens catch
stormwater and slowly filter it into the ground, meaning less water runs off lawns into our storm
sewers, helping prevent flooding and erosion in our streams.
• Keep waste out of storm drains. Sweep driveways and sidewalks clean. Remove debris and residue
that could end up in a storm drain from concrete and paved areas around your house. Never discard
trash or yard waste down storm drains or in the street.

LIBERTY UTILITIES DEPARTMENT’S WATER SUPPLY
The Missouri Department of Natural Resources conducted a source water assessment to determine the
susceptibility of our water source to potential contaminants. This process involved the establishment of source
water area delineations for each well or surface water intake
and then a contaminant inventory was performed within those
delineated areas to assess potential threats to each source.
Assessment maps and summary information sheets are available at
www.drinkingwater.missouri.edu
To access the maps for your water system you
will need the State-assigned identification code. The code for
Liberty is MO1010466. Some Liberty residents receive water
from the City of Kansas City, Missouri water system (see map
on page 6). The code for Kansas City is MO1010415. The Source
Water Inventory Project maps and information sheets provide
a foundation upon which a more comprehensive source water
protection plan can be developed.
WHAT IS THE SOURCE OF MY WATER?
The sources of drinking water (both tap water and bottled water)
include rivers, lakes, streams, ponds, reservoirs, springs and
groundwater 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.

WHAT IS IN MY 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 EPA’s Safe Drinking Water Hotline at
800.426.4791.
Contaminants that may be present in raw water (source
water before we treat it) 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.
• Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and
mining activities.
• 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.
In order to ensure that tap water is safe to drink, the Department of Natural Resources prescribes regulations
that limit the amount of certain contaminants in water provided by public water systems. Department of Health
regulations establish limits for contaminants in bottled water, which must provide the same protection for public
health.
WATER QUALITY TESTING RESULTS - City of Liberty (#MO1010466)
The tables on page 8-9 of the report list all the drinking water contaminants detected during the 2020 calendar
year in water provided by the City of Liberty. The presence of these contaminants in the water does not
necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table
is from testing done January 1 through December 31, 2020. The State has reduced monitoring requirements
for certain contaminants to less often than once per year because the concentrations of these contaminants are
not expected to vary significantly from year to year. Records with a sample year more than one year old are still
considered representative. No data older than five years need be included. If more than one sample is collected
during the monitoring period, the “range” will show the lowest and highest tested results. The “Highest LRAA”,
or highest value, must be below the maximum contaminant level (MCL) or the contaminant has exceeded the
level of health based on standards and a violation is issued to the water system.
The Liberty Utilities Department will provide a printed hard copy of this CCR upon request. To request a copy
