Understanding your water quality
Get help interpreting water test results
Have you had water from a private well or spring tested at a lab? If you have the results but aren’t sure what they mean, the Water Quality Interpretation Tool can help. This tool allows you to enter your data to see if it meets common standards for drinking, irrigation, and livestock.
Learn about Utah’s drinking water quality standards
There are State standards for over 100 potential contaminants in drinking water. For example, the maximum allowable level for nitrates in drinking water is 10 milligrams per liter.
Find your annual drinking water consumer confidence report
Each year, every community water system must provide customers with a Consumer Confidence Report (CCR). This report gives an overview of your drinking water system and its quality. For background information, see Consumer Confidence Report Preparation. You can often find this report on your water supplier’s website, and you can also contact your water supplier directly for a copy of their report. Find out which water system serves you here.
Check your water system’s rating
We assign a rating (such as “Approved” or “Not Approved”) to each public water system in the state based on its condition and performance. You can find your system’s rating at Waterlink.utah.gov.

Signs of common water quality problems (US EPA)
Does your water have a funny odor, taste, or appearance? The EPA provides a general guide to help determine the cause. While some issues only affect taste and smell, others can be serious. If you think there is a serious problem, see the guidance for emergencies.
Guidance for people with special health needs (US EPA)
People with weakened immune systems (such as those with HIV/AIDS or undergoing chemotherapy) may be more susceptible to microbial contaminants in drinking water.
Information on waterborne disease
While U.S. water supplies are among the safest in the world, the risk of waterborne disease still exists. This resource on recognizing waterborne disease is intended for health care professionals but may be informative for the public. (Registration is required).
Common questions
Who regulates bottled water?
Bottled water in Utah is regulated by the Utah Department of Agriculture and Food.
Information on private wells and springs
Most Utahns get water from a public water system, but some use private wells or springs. These are not regulated by the Division of Drinking Water. Your local health department may have rules for private supplies. For advice, see the EPA’s guide on Private Drinking Water Wells.
Where can I get my water tested?
This list of Utah-certified labs can test your water for a fee. Note that your public water supplier already tests its water routinely, and results may be in your Consumer Confidence Report.
Fluoride
During the 2025 Legislative Session, Utah lawmakers passed HB81 – Fluoride Amendments, which prohibits the addition of fluoride to public drinking water in Utah starting May 7, 2025.
