Not just pure, but proven.
A new standard in transparency.
Loonen Water Composition
WHY WE CARE: Supports normal bone structure and nerve signaling, and helps maintain overall mineral balance.
WHY WE CARE: Provides trace minerals that support hydration and enhance taste.
WHY WE CARE: Supports normal fluid balance and muscle function.
WHY WE CARE: Supports normal muscle function and everyday energy processes, while contributing to a smooth, balanced taste.
WHY WE CARE: A TDS of 120 reflects a balanced mineral content that enhances taste and supports hydration.
WHY WE CARE: Clean, neutral, and easy to drink.
These minerals are included to support a balanced mineral profile and everyday hydration, not to serve as dietary supplements or medical treatments.
Key Lab Results
Transparency means data you can see and understand. Below are key lab results from our latest finished-goods testing, including the top contaminants we measure and why those matter. For comprehensive, line-by-line results, open the PDF reports linked below.
ND = none of these analytes have been detected at or above the specified detection level
MCL = maximum contaminant level as established by the US FDA for bottled water
RL = laboratory reporting limit for method
NONE = no applicable MCL exists for that analyte as of the publication date

Our Source
Natural springs in southern California. Protected catchment and controlled transport preserve natural character.
How It’s Bottled
Proprietary filtration process removes impurities. Careful mineral balance preserves a clean, natural taste. All processing and bottling takes place in a sealed, contact-free line.
How It’s Tested
Rigorous third-party testing, at the source, from purification to the final sealed bottles. Transparency shouldn’t be optional.

Historical Test Results:
November 11, 2025 - Still Water
November 11, 2025 - Sparkling Water
All analyses were conducted using EPA-approved methods by accredited independent third-party laboratories. Each laboratory is certified to perform testing in accordance with FDA and EPA bottled water standards. Because we monitor an extensive list of parameters, including many that go beyond FDA requirements, we partner with multiple specialized laboratories to ensure the most accurate and comprehensive results. A complete listing of analytical methods is available upon request.
