If you would like to observe the decision - making processes that
affect drinking water quality, please attend the regularly
scheduled meeting of the Village Board /City Council. If you
would like to participate in the process, please contact the
Village /City Clerk to arrange to be placed on the agenda of the
meeting of the Village Board/City Council.
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 FPA's Safe Drinking Water Hotline
(800- 426- 4791).
Source Water Assessment Availability
The Nebraska Department of Environmental Quality (NDEQ) has
completed the Source Water Assessment. Included in the
assessment are a Wellhead Protection Area map, potential
contaminant source inventory, vulnerability rating, and source
water protection information. To view the Source Water
Assessment or for more information please contact the person
named above on this report or the NDEQ at (402) 471 -6988 or
go to www.dec.state.n%us
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. FDA regulations
establish limits for contaminants in bottled water which must
provide the same protection for public health.
Sources of Drinking Water
Tho en „rcac of rtrinkinn water Ihnth tan 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.
The source of water used by City Of Blair is surface water.
Contaminants that may be present In source water Inc
* 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 storm water 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 storm water 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 storm water runoff, and septic systems.
* Radioactive contaminants, which can be naturally- occurring or
be the result of oil and gas production and mining activities.
Drinking Water Health Notes
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
Cryptosporidfum and other microbial contaminants are available from
the Safe Drinking Water Hotline (800- 426- 4791).
Infants, young children, and pregnant women are typically more
vulnerable to load 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. Flushing your
tap for 30 seconds to 2 minutes before using your tap water will clear
the line of any lead that may have leached into the water while the
line was idle. Additional information is available from the Safe
Drinking Water Hotline (800- 426 -4791) or the DHHS/Division of
Public Health /Offlea of Drinking Water (402- 471 - 2541).

How to Read the Water Quality Data Table:
The EPA and State Drinking Water Program establish the sale drinking
water regulations that limit the amount of contaminants allowed in drinking
water. The table shows'the concentrations of detected substances in
comparison to the regulatory limits. Substances not detected are not
included in the table, The state requires monitoring of certain contaminants
less than once per year because the concentrations of these contaminants
do not change frequently. Tlierefore, some of this data may be older than
one year.
MCL (Maximum Contaminant Level) —The highest level of a
contaminant that is allowed in drinking water. MCLs are set as close to the
MCLGs as feasible using the best available treatment technology.
MCLG (Maximum Contaminant Level Goal) —The level of a contaminant
In drinking water below which there is no known or expected risk to health.
MCLGs allow for a margin of safety,
AL (Action Level) —The concentration of a contaminant which, if
exceeded triggers treatment or other requirements which a water system
must follow.
MRDL (Maximum Residual Disinfectant Level) —The highest level of a
disinfectant allowed in drinking water.
MRDLG (Maximum Residual Disinfectant Level Goal) —The level of
disinfectant in drinking water below which there is no known or expected
risk to health.
WA — Not applicable.
Units in the Table;
ND — Not detectable.
ppm (parts per million) = mg/L (milligrams per liter) — One ppm or one
mg/L corresponds to 1 gallon of water in 10,000 gallons of water.
ppb (parts per billion) — One ppb corresponds to 1 gallon of water in
10,000,000 gallons of water.
pCUL (Picocuries per liter) — Radioactivity concentration unit.
ug/L ( micrograms per liter) — Measurement of radioactivity.
NTU (Nephelometric Turbidity Units) —A measure of water clarity.
QRAA (Quarterly Running Annual Average) — An ongoing annual
average calculation of data from the most recent four quarters.
90” Percentile — Represents the highest value found out of 90% of the
samples taken in a representative group. if the 90" percentile is greater
than the action level, it will trigger a treatment or other requirements that a
water system must follow.
TT (Treatment Technique) — A required process intended to reduce the
level of a contaminant in drinking water.
NOTICE — This report will not be mailed to individual water customers. Please contact the City of Blair,
218 S. 16th St., Blair, NE 68008 at (402) 426 -4191 or at cityofbiair @ci.blair.ne.us to request a copy.
