Lead and Copper Information

Corrosion of household plumbing, fittings, and fixtures may cause metals such as lead and copper to enter drinking water. Herriman City conducts lead and copper tap sampling every three years at selected locations in the Hi-Country Estates 1 water system to monitor corrosion levels.

Service Line Inventory

Herriman City has completed an initial lead service line inventory for the Hi-Country Estates 1 water system. The inventory includes information about materials used to connect water mains to homes and buildings. For questions about the inventory, contact the Herriman City Water Department at 801-446-5323.

Drinking Water Source Protection

A Drinking Water Source Protection Plan is maintained for the Hi-Country Estates 1 water system. The plan identifies:

Source protection zones
Potential contamination sources, such as septic systems, roads, residential areas, and industrial areas
Management strategies to reduce contamination risks

The system’s water sources are rated as having a medium level of susceptibility. To view the plan or ask questions, please contact the Herriman City Water Department.

Cross Connections and Water Safety

A cross connection is an unintended link between drinking water and potential contaminants. Common examples include:

Garden hoses lying in puddles
Lawn sprinkler systems after applying fertilizers or pesticides
Improper connections to a secondary, untreated water line

Improper connections can compromise water quality and pose health risks. Do not install or allow unapproved plumbing connections at home. Contact Herriman City for information on how to protect the water supply.

2025 Water Quality Test Results

Water Testing and Monitoring

Hi-Country Estates 1 regularly tests drinking water as required by federal and Utah state law. These tests measure a range of potential contaminants. While all drinking water sources may contain naturally occurring substances, they are generally not harmful at low levels. Removing 100% of contaminants is often unnecessary and cost-prohibitive.

Test Results

The following table shows the results of 2025 monitoring, including key indicators from prior years as required. All contaminants listed were within regulatory limits.

Understanding the Terms

Non-Detects (ND) - laboratory analysis indicates that the constituent is not present.
ND/Low - High - For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table.
Parts per million (ppm) or Milligrams per liter (mg/L) - one part per million corresponds to one minute in two years or a single penny in $10,000.
Parts per billion (ppb) or Micrograms per liter (µg/L) - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
Parts per trillion (ppt) or Nanograms per liter (ng/L) - one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.
Parts per quadrillion (ppq) or Picograms per liter (pg/L) - one part per quadrillion corresponds to one minute in 2,000,000,000 years, or one penny in $10,000,000,000,000.
Picocuries per liter (pCi/L) - a measure of the radioactivity in water.
Millirems per year (mrem/yr) - measure of radiation absorbed by the body.
Million fibers per liter (MFL) - measure of asbestos fibers longer than 10 micrometers.
Nephelometric Turbidity Unit (NTU) - measure of water clarity; turbidity above 5 NTU is just noticeable to the average person.
Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.
Treatment Technique (TT) - a required process intended to reduce the level of a contaminant in drinking water.
Maximum Contaminant Level (MCL) - the highest level of a contaminant allowed in drinking water. MCLs are set as close to MCLGs as feasible using the best available treatment technology.
Maximum Contaminant Level Goal (MCLG) - the level of a contaminant in drinking water below which there is no known or expected risk to health; allows for a margin of safety.
Maximum Residual Disinfectant Level (MRDL) - the highest level of a disinfectant allowed in drinking water. There is convincing evidence that the addition of a disinfectant is necessary for the control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG) - the level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of disinfectants used to control microbial contaminants.
Date - because of required sampling time frames (e.g., yearly, every 3, 4, or 6 years), sampling dates may appear outdated.
Waivers (W) - some water systems receive waivers exempting them from sampling certain chemicals when those chemicals are not used or stored near drinking-water sources; waivers tie into Drinking Water Source Protection Plans.

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 mean the water poses a health risk. More information about contaminants and possible health effects is available from the EPA’s Safe Drinking Water Hotline at 800-426-4791.

Drinking water comes from sources such as rivers, lakes, streams, reservoirs, springs, and wells. As water moves over land or through the ground, it can dissolve naturally occurring minerals and, in some cases, radioactive material. It can also pick up substances from animals or human activity.

Common contaminant categories include:

Microbial contaminants – viruses or bacteria from sewage treatment plants, septic systems, livestock operations, and wildlife.
Inorganic contaminants – salts and metals that occur naturally or enter water through urban stormwater runoff, industrial discharge, oil and gas production, mining, or farming.
Pesticides and herbicides – chemicals used in agriculture, landscaping, and residential yards that can wash into streams or soak into groundwater.
Organic chemical contaminants – synthetic and volatile compounds generated by industrial processes, petroleum production, gas stations, stormwater runoff, and septic systems.
Radioactive contaminants – elements released from natural deposits, mining activities, or oil and gas production.

To help ensure tap water is safe to drink, the EPA limits the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration sets limits for contaminants in bottled water, which must provide the same protection for public health.

Lead Exposure Risks and Prevention

Lead can cause serious health issues, especially for pregnant women and young children. While Herriman City manages the Hi-Country Estates 1 water system, lead typically comes from plumbing materials inside buildings.

What you can do:

Run tap water for 30 seconds to 2 minutes if the water has been sitting for several hours
Use a filter to reduce lead. The City recommends a filter certified by the American National Standards Institute
Inspect and remove lead components from home plumbing

If you're concerned, you may wish to test your water. Call 801-446-5323 or visit www.epa.gov/safewater/lead for more information.

Vulnerable Populations

Certain individuals may be more sensitive to contaminants in drinking water. These include:

People undergoing chemotherapy
Individuals with organ transplants
People with HIV/AIDS or other immune disorders
The elderly and infants

These individuals should seek guidance from health care providers. Additional guidelines and information are available from the Safe Drinking Water Hotline at 800-426-4791.

Protecting Shared Water Resources

Herriman City works to provide clean, safe drinking water to the Hi-Country Estates 1 water system. Residents are encouraged to help protect local water sources, which are essential to the health and future of the community.
