City of Idaho Falls Water Company

The Safe Drinking Water Act of 1996 requires water utilities to provide customers with detailed information about their water quality. The City of Idaho Falls takes pride in its water quality and welcomes this opportunity to share that information with residents.

To ensure water safety and quality, water samples are regularly collected and analyzed. This testing data is provided to and monitored by both the U.S. Environmental Protection Agency (EPA) and the State of Idaho Department of Environmental Quality (DEQ). Idaho Falls water consistently meets quality standards, and all test results are maintained by the City's Water Division, DEQ, and EPA.

Idaho Falls obtains its water from nineteen (19) deep wells located throughout the city. These wells draw from the East Snake River Plain Aquifer, which provides naturally high-quality water. A small amount of chlorine is added as a precautionary measure to protect against potential microbial contaminants.

Municipal water (including bottled water) comes from various sources including streams, lakes, rivers, ponds, reservoirs, springs, and wells. As water travels across land or underground, it dissolves natural minerals and, in some cases, radioactive materials, and may pick up substances from animal presence or human activity.

Potential contaminants in source water before treatment include:

• Microbial contaminants from sewage treatment plants, septic systems, agricultural operations, and wildlife
• Inorganic contaminants like salts and metals, either naturally occurring or from urban runoff, wastewater discharges, oil/gas production, mining, or farming
• Pesticides and herbicides from agriculture and residential uses
• Radioactive contaminants that occur naturally
• Organic chemical contaminants, including synthetic and volatile compounds from industrial processes, petroleum production, gas stations, urban runoff, and septic systems

To ensure tap water safety, EPA establishes regulations limiting contaminant levels in public water systems. We treat our water according to DEQ and EPA standards. The FDA similarly regulates bottled water for public health protection. All drinking water, including bottled water, may reasonably contain at least small amounts of some contaminants, which doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, call the EPA's Safe Drinking Water Hotline at 800-426-4791.

Frequently Asked Questions

1. Where does City of Idaho Falls water come from?
   City of Idaho Falls supplies groundwater to Idaho Falls, Idaho.
2. Does City of Idaho Falls test its tap water?
   Yes. Like every public water system, City of Idaho Falls must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact City of Idaho Falls?
   Call 208-612-8100 or visit 308 Constitution Way, Idaho Falls, ID 83402, or use the contact options on the utility’s website.
4. Does City of Idaho Falls water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is City of Idaho Falls water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.

Arizona Water Company employees wear uniforms with visible company identification and drive vehicles displaying the company logo. All employees carry photo ID badges. Staff will never request entry to check water without prior arrangement and only enter homes for requested water audits.
