Our Amazing Water

Eldorado Natural Spring Water starts in the Colorado high country and emerges at one of the most distinctive artesian springs in North America. For generations, people have come to Eldorado Springs for water they trust—drawn by its source, its purity, and its consistency.

Where Our Spring Water Comes From

Our spring is located in Eldorado Springs, Colorado, just south of Boulder.

• The water begins as rain and snow east of the Continental Divide
• Over millennia it slowly filters through layers of rock and soil, entering a deep aquifer
• That aquifer passes beneath Eldorado Springs at a depth of roughly 8,000 feet
• Under natural artesian pressure, the water rises and emerges at our spring

This long, underground journey naturally filters the water and shapes its mineral profile before it ever reaches our bottling facility. The result is a protected, reliable source that has supplied Eldorado water for generations.

Water and Health

Staying hydrated is one of the simplest daily habits you can use to support overall wellness.

A common guideline is to drink about half an ounce of water for every pound of body weight per day (your needs may vary based on activity level, climate, and individual health). Having great-tasting, easy-to-access water on hand at home, at work, and on the go makes it more likely you’ll actually drink what your body needs.

Our blog explores how hydration supports energy, focus, exercise, and everyday health in more detail.

FAQ: Our Water

Where is Eldorado Natural Spring Water sourced?

Our water comes from an artesian spring in Eldorado Springs, Colorado, just outside Boulder. It originates as rain and snow near the Continental Divide, travels underground through a deep aquifer system, and naturally rises to the surface at our spring.

What makes Eldorado different from “regular” bottled water or tap water?

Many bottled waters are purified municipal water, and most tap water is treated with disinfectants like chlorine. Eldorado is natural spring water from a single protected source, with a consistent mineral profile and no added flavors or sweeteners. It is bottled at the source and tested to meet strict spring water standards.

Is Eldorado water tested for safety and quality? Yes. Our water is tested regularly for microbiological safety, mineral content, and a wide range of potential contaminants. We also undergo routine inspections and audits to verify that our safety and quality systems are working as designed.

Does Eldorado add anything to the water?

No. Eldorado Natural Spring Water is bottled as it emerges from the artesian spring, with its naturally occurring minerals and characteristics intact. We do not add flavors, sweeteners, or disinfecting chemicals.

Is Eldorado water good for everyday drinking and hydration?

Eldorado is designed to be an everyday drinking water for homes, offices, and active lifestyles. Its natural source, consistent mineral content, and careful quality control make it a practical choice for regular hydration throughout the day.
