2015 Drinking Water Report
The City of Saint Joseph is issuing the results of monitoring done on its drinking water for the period from
January 1 to December 31, 2015. The purpose of this report is to advance consumers' understanding of
drinking water and heighten awareness of the need to protect precious water resources.
Source of Water
The City of Saint Joseph provides drinking water to its residents from a groundwater source: six wells ranging
from 64 to 75 feet deep,that draw water from the Quat. Water Table aquifer. .
The Minnesota Department of Health has made a determination as to how vulnerable our systems' source(s) of
water may be to future contamination incidents. If you wish to obtain the entire source water assessment
regarding your drinking water,please call 651-201-4700 or 1-800-818-9318 (and press 5) during normal
business hours. Also, you can view it on line at www.health.state.mn.us/divs/eh/water/swp/swa.
Call Terry Thene at 320.363.7201 or by email at tthene(�a,cit�tjoseph.com if you have questions about the
City of Saint Joseph drinking water or would like information about opportunities for public participation in
decisions that may affect the quality of the water.
Results of Monitoring
No contaminants were detected at levels that violated federal drinking water standards. However, some
contaminants were detected in trace amounts that were below legal limits. The table that follows shows the
contaminants that were detected in trace amounts last year. (Some contaminants are sampled less frequently
than once a year; as a result, not all contaminants were sampled for in 2015. If any of these contaminants were
detected the last time they were sampled for, they are included in the table along with the date that the detection
occurred.)
Key to abbreviations:
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.
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.
MRDL—Maximum Residual Disinfectant Level.
MRDLG—M�imum Residual Disinfectant Level Goal.
AL—Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other
requirement which a water system must follow.
90th Percentile Level—This is the value obtained after disregarding 10 percent of the samples taken that had the
highest levels. (For example, in a situation in which 10 samples were taken, the 90th percentile level is
determined by disregarding the highest result,which represents 10 percent of the samples.) Note: In situations
in which only 5 samples are taken,the average of the two with the highest levels is taken to determine the 90th
percentile level.

home plumbing. City of Saint Joseph 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.
Monitoring may have been done for additional contaminants that do not have MCLs established for them and
are not required to be monitored under the Safe Drinking Water Act. Results may be available by calling 651-
201-4700 or 1-800-818-9318 during normal business hours.
Compliance with National Primary Drinking Water Regulations
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 cantaminants, 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.
In order to ensure that tap water is safe to drink, the U. S. Environmental Protection Agency(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.
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 Safe Drinking Water Hotline at 1-800-426-4791.
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 at 1-800-426-4791.

DATE: April 1, 2016
TO: Saint Joseph, PWSID 1730033
FROM: Karla R. Peterson, Supervisor
Community Public Water Supply Unit
Drinking Water Protection Section
SUBJECT: Consumer Confidence Report— Distribution Requirements
All community water systems must distribute a drinking water report known as a Consumer
Confidence Report(CCR) annually to their customers before July 1, 2016.
Your system may reformat the CCR and/or add additional information about your water system
(treatment processes, upgrades planned, etc.) however, that is not necessary. The CCR that
we have provided will satisfy the requirements. If you choose to reformat the CCR, all the
information in the Minnesota Department of Health (MDH) CCR must be included in your newly
reformatted CCR.
You must add your phone number to the grey shaded area on Page 1 so customers can call
with questions or request additional information. There may be other grey shaded areas in your
CCR—it is your responsibility to fill in those areas with accurate information.
Distribution:
The requirements to distribute your CCR are determined by population. The population served
by your water supply is 6629. The option(s) on how to distribute your CCR are listed on the
enclosed Certification Form. Please indicate what option(s)you chose on the Certification
Form. The Certification Form is to be returned to MDH, along with a copy of the CCR that was
distributed to your customers. Even if you are distributing the MDH CCR, you must fill in the
grey shaded area(s) and return a copy of the CCR and the completed Certification Form to
MDH by July 1, 2016.
You are required to keep a copy of the CCR for at least three years. Failure to produce and
distribute a CCR as required—as well as failure to submit a copy of the CCR and the
Certification Form to MDH by July 1, 201C�may result in enforcement actions, including
fines.
