The name "El Dorado water" can be confusing because it refers to different products and municipalities, each with its own distinct source and treatment process. For consumers, understanding these differences is crucial for determining the potential health benefits and safety of their water.
The Quality of Eldorado Natural Spring Water
Eldorado Natural Spring Water, sourced from artesian springs in Eldorado Springs, Colorado, is widely praised for its high quality. This water originates from rain and snowmelt east of the Continental Divide, which then flows into a deep aquifer. The water is naturally filtered through sandstone layers under immense artesian pressure, which forces it to the surface and removes impurities.
Key characteristics of the Colorado spring water:
- Naturally Mineral-Rich: The water picks up essential minerals like calcium and magnesium as it flows through rock formations. These naturally occurring electrolytes contribute to its flavor and health benefits.
- Naturally Alkaline pH: With a pH typically around 7.4, the water is naturally alkaline, which some consumers prefer for its smoother taste.
- Low in Total Dissolved Solids (TDS): Despite being mineralized, its TDS is relatively low (around 73 mg/L), giving it a light, clean taste.
- Untreated Purity: The company emphasizes that its spring water is not chemically treated, relying on its natural purification process.
- Awards and Certifications: The water has won multiple awards for taste and is regularly inspected by regulatory bodies like the FDA and state health departments.
Water Quality in El Dorado Municipalities
In contrast to the bottled spring water, municipal tap water in various cities named El Dorado is treated and sourced differently. The quality and potential concerns can vary by location.
El Dorado, Kansas, Tap Water
The City of El Dorado, Kansas, sources its tap water from the El Dorado Reservoir.
- The raw lake water undergoes extensive treatment, including disinfection, flocculation, sedimentation, and filtration, to meet drinking water standards.
- Fluoride is added to the water.
- Regular testing ensures compliance with safety regulations.
El Dorado, Arkansas, Tap Water
In El Dorado, Arkansas, testing has shown some contaminants related to the treatment process.
- A 2020 Consumer Confidence Report identified the presence of Trihalomethanes (TTHMs), which are disinfection by-products.
- While within legal limits, some health concerns are associated with long-term consumption of TTHMs.
- The system also participated in monitoring for PFAS and lithium.
El Dorado Area, New Mexico, Tap Water
The Environmental Working Group (EWG) has reported on tap water quality for the El Dorado Area Water and Sanitation District in New Mexico, identifying specific contaminants above EWG's health guidelines.
- Elevated levels of Total Trihalomethanes (TTHMs) and Radium were detected in monitoring data from 2018-2024.
- These by-products and naturally occurring radioactive elements highlight potential health risks that may not be a concern with the Colorado spring water.
What are the potential health benefits?
Drinking water is essential for hydration, and for some, the added minerals in natural spring water offer extra advantages.
- Bone Health: Mineral water high in calcium, like Eldorado spring water, can contribute to bone health. Studies show that the bioavailability of calcium from mineral water can be comparable to or better than that from dairy.
- Heart Health: The presence of minerals such as magnesium can help regulate heart rhythm and aid in muscle function.
- Overall Hydration: Both tap and spring water provide necessary hydration, which supports cognitive function, digestion, and detoxification.
Comparison: Eldorado Spring Water vs. El Dorado Tap Water
| Feature | Eldorado Natural Spring Water (Colorado) | El Dorado Municipal Tap Water (Kansas, Arkansas, New Mexico, etc.) | 
|---|---|---|
| Source | Protected artesian spring fed by mountain snowmelt and rain | Lake water, rivers, or local groundwater, depending on the municipality | 
| Processing | Natural filtration through sandstone layers; no chemical treatment | Extensive chemical treatment and filtration to meet regulatory standards | 
| Mineral Content | Naturally mineral-rich with balanced electrolytes like calcium and magnesium | Varies by location; minerals are often added or removed during treatment | 
| pH Level | Naturally alkaline, around 7.4 | Varies, often adjusted during treatment; can be acidic or alkaline | 
| Contaminants | Tested to be free from common contaminants and pesticides | Potential for disinfection by-products (TTHMs) or other contaminants, depending on location and monitoring | 
| Taste | Often described as clean, smooth, and refreshing due to balanced minerals and neutral pH | Can have varying taste due to different mineral compositions and treatments, such as added chlorine | 
| Sustainability | Uses 100% recycled plastic in its bottles; some customer complaints regarding delivery logistics and environmental impact of bottled water | Reduces reliance on single-use plastic bottles, but with varying local environmental impacts | 
Conclusion
The quality of "El Dorado water" is not universal and depends entirely on the source. For bottled water, Eldorado Natural Spring Water from Colorado offers a naturally pure, mineral-rich option that is free of chemical treatment. However, tap water from municipalities in areas named El Dorado undergoes standard treatment processes that can introduce disinfection by-products, and some locations may show contaminants depending on testing and local conditions. Ultimately, while Eldorado Natural Spring Water is a high-quality bottled product, consumers should be mindful of the different water types and their sources, especially when considering cost and environmental impact. To understand the specifics of your local tap water, review your municipality's annual water quality report.

Additional Considerations
Can drinking mineral water replace my mineral supplement intake?
No, while mineral water like Eldorado provides some essential minerals, it should not be relied upon as the sole source of minerals in your diet. A balanced diet remains the best way to ensure adequate mineral intake.
Is natural spring water always better than tap water?
Not necessarily. While spring water is naturally filtered and mineralized, many municipal tap water systems are highly regulated and provide perfectly safe drinking water, often at a lower cost and with less environmental impact than bottled options. The best choice depends on individual preferences and priorities.
How can I check my local El Dorado tap water quality?
For municipal tap water, check your city or utility's website for the annual Consumer Confidence Report (CCR), which details water test results and contaminant levels. For example, the City of El Dorado, Kansas, has one available on its site.
Are there any downsides to Eldorado Natural Spring Water?
Potential downsides include the environmental impact of single-use plastic bottles (though Eldorado uses recycled materials) and the potential for bottle-leached chemicals like BPA or microplastics, though the company notes testing shows very low or non-existent levels of harmful chemicals. Additionally, some customer service complaints regarding delivery service have been noted in reviews.
