For Calendar Year 2016
Public Water System ID: CO0162122
Esta es informacion importante. Si no la pueden leer, necesitan que alguien se la traduzca.
We are pleased to present to you this year's water quality report. Our constant goal is to provide you with a safe and dependable
supply of drinking water. Please contact STAN LINKER at 970-352-1284 with any questions about the Drinking Consumer
Confidence Rule (CCR) or for public participation opportunities that may affect the water quality.
General Information
All 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 the
water poses a health risk. More information about contaminants and
potential health effects can be obtained by calling the Environmental
Protection Agency's Safe Drinking Water Hotline (1-800-426-4791)
or by visiting http://water.epa.gov/drink/contaminants.
Some people may be more vulnerable to contaminants in drinking
water than the general population. Immunocompromised 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 of infections. These people should seek advice
about drinking water from their health care providers. For more
information about contaminants and potential health effects, or to
receive a copy of the U.S. Environmental Protection Agency (EPA)
and the U.S. Centers for Disease Control (CDC) guidelines on
appropriate means to lessen the risk of infection by Cryptosporidium
and microbiological contaminants call the EPA Safe Drinking Water
Hotline at (1-800-426-4791).
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. Contaminants that may
be present in source water include:
•Microbial contaminants: viruses and bacteria that may come from
sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
•Inorganic contaminants: 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: may come from a variety of sources,
such as agriculture, urban stormwater runoff, and residential uses.
•Radioactive contaminants: 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 byproducts of industrial processes and
petroleum production, and also may come from gas stations, urban
storm water runoff, and septic systems.

CENTRAL WELD CNTY WD, PWS ID: CO0162122
In order to ensure that tap water is safe to drink, the Colorado
Department of Public Health and Environment prescribes
regulations limiting the amount of certain contaminants in water
provided by public water systems. The Food and Drug
Administration regulations establish limits for contaminants in
bottled water that must provide the same protection for public
health.
Lead in Drinking Water
If present, elevated levels of lead can cause serious health problems
(especially for pregnant women and young children). It is possible
that lead levels at your home may be higher than other homes in the
community as a result of materials used in your home's plumbing. If
you are concerned about lead in your water, you may wish to have
your water tested. 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. Additional information on lead in drinking water, testing
methods, and steps you can take to minimize exposure is available
from the Safe Drinking Water Hotline (1-800-426-4791) or at
http://www.epa.gov/safewater/lead.
Source Water Assessment and Protection (SWAP)
The Colorado Department of Public Health and Environment has
provided us with a Source Water Assessment Report for our water
supply. For general information or to obtain a copy of the report
please visit http://wgcdcompliance.com/ccr. The report is located
under "Source Water Assessment Reports", and then "Assessment
Report by County". Select WELD County and find 162122;
CENTRAL WELD CNTY WD or by contacting STAN LINKER at
970-352-1284. The Source Water Assessment Report provides a
screening -level evaluation of potential contamination that could
occur. It does not mean that the contamination has or will occur. We
can use this information to evaluate the need to improve our current
water treatment capabilities and prepare for future contamination
threats. This can help us ensure that quality finished water is
delivered to your homes. In addition, the source water assessment
results provide a starting point for developing a source water
protection plan. Potential sources of contamination in our source
water area are listed on the next page.
Please contact us to learn more about what you can do to help
protect your drinking water sources, any questions about the
Drinking Water Consumer Confidence Report. to learn more about
our system, or to attend scheduled public meetings. We want you,
our valued customers. to be informed about the services we provide
and the quality water we deliver to you every day.

Unregulated Contaminants***
***More information about the contaminants that were included in UCMR3 monitoring can be found at: http://www.drinktap.org/water-info/whats-in-mv-
water/unregulated-contaminant-monitoring-rule.aspx. Learn more about the EPA UCMR at: http://www.epa.gov/dwucmr/learn-about-unregulated-
contaminant-monitoring-rule or contact the Safe Drinking Water Hotline at (800) 426-4791 or http://water.ena.gov/drink/contact.cfm.
EPA has implemented the Unregulated Contaminant Monitoring Rule (UCMR) to collect data for contaminants that are suspected to be
present in drinking water and do not have health -based standards set under the Safe Drinking Water Act. EPA uses the results of UCMR
monitoring to learn about the occurrence of unregulated contaminants in drinking water and to decide whether or not these contaminants
will be regulated in the future. We performed monitoring and reported the analytical results of the monitoring to EPA in accordance with
its Third Unregulated Contaminant Monitoring Rule (UCMR3). Once EPA reviews the submitted results, the results are made available in
the EPA's National Contaminant Occurrence Database (NCOD) (http://www.epa.gov/dwucmr/national-contaminant-occurrence-database-
ncod) Consumers can review UCMR results by accessing the NCOD. Contaminants that were detected during our UCMR3 sampling and
the corresponding analytical results are provided below.

Lead in Drinking Water
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 Carter Lake
Filter Plant 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 elevated lead levels in your home's water, you may wish to have your water tested.
Additional information is available from the EPA Safe Drinking Water Hotline at 1-800-426-4791 or at

***CWCWD CROSS CONNECTION CONTROL PROGRAM***
The Colorado Department of Public Health & Environment (CDPHE) requires every municipal water supplier to develop, implement. and
maintain a comprehensive Cross Connection Control Program designed to safeguard the public water supply. Central Weld County Water
District (CWCWD), as required by regulations, has adopted such a program. For the District to remain compliant, cooperation from all
residential and commercial property owners is essential and a critical part of this program. Should you ever receive any requests for
information from CWCWD or our subcontractor Aqua Backflow, who manages this program for the District, please respond accordingly.
Aqua Backflow specializes in cross connection control program management and is familiar with the regulations and requirements for
testing, repairs, and maintenance of backflow devices. If you have or require backflow protection because you have a pool, irrigation
system, fire sprinkler system, heating system/boilers, alternate water source, or similar, compliance is mandatory with these
regulations. One of the requirements of the program is to conduct a survey of Central Weld County Water District customers. Some
surveys will be in person, some will be by mail and some will be a combination of both. Should you have any questions, you may contact
CWCWD at 970-352-1284.
(Sample Drawing Only) Types of backflow protection and locations will vary due to hazards present on the customer's property.
Please consult with CWCWD personnel prior to backflow installation. Thank you.
