Water Quality Report 2020
UNIVERSITY OF UTAH WATER SYSTEM, NO. 18057
We're pleased to present to you this year's Annual Drinking Water Quality 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. The University of Utah Water system is designated as a consecutive connection to Salt Lake City’s public water system as we purchase all of our drinking water from Salt Lake City. We are pleased to report that our drinking water meets federal and state requirements.
The following table shows the results of our lead and copper monitoring for the period of July 1st to December 31st, 2020. We’ve also included the water quality data provided by Salt Lake City as they are our water source. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It's important to remember that the presence of these constituents does not necessarily pose a health risk.
DO I NEED TO TAKE SPECIAL PRECAUTIONS?
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 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).
ADDITIONAL INFORMATION FOR LEAD
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. University of Utah 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.
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.
SIGNIFICANT DEFICIENCIES
The Utah Division of Drinking Water conducted a sanitary survey of our water system on October 15, 2020. The table below lists the significant deficiencies that were identified and the corrective action plan and deadlines we are following to address them.
| Deficiency | Survey Date | Corrective Action Plan |
| End of storage tank overflow pipe lacks no. 4 screen | 10/15/2020 | Construction project currently in place to correct this deficiency by November 1, 2021 |
| End of storage tank overflow lacks a clearance of between 12 and 24 inches from ground surface | 10/15/2020 | Construction project currently in place to correct this deficiency by November 1, 2021 |
| In‐line booster pump station lacks redundancy to meet peak demand with one pump out of service | 10/15/2020 | Submit documentation showing our pump station has redundancy to meet peak demand by March 22, 2022 |
