Part 2: Kröplin

Tools and rituals for water-intelligent living, distilled weekly.

The Water-Intelligent Living Series

When we talk about healthy water, we often begin with chemistry: minerals, purity, contamination.

What if water behaves not only as a substance, but as a dynamic system shaped by its environment?

Bernd Kröplin, is a German engineer and former professor at the University of Stuttgart. He did not come to water as a chemist or mystic.

His early research focused on the human body understood as a physical system.

Kröplin worked on research related to human health in extreme environments, including spaceflight contexts.

He explored bio-resonance approaches, in an attempt to understand how biological systems respond to subtle signals. That line of inquiry led him to a simple but foundational element of the body: water.

What happens, he asked, if we look at water closely?

Using dark-field microscopy, Kröplin began observing tiny droplets of water. Under this form of illumination, the droplets did not appear smooth or uniform. Instead, they revealed intricate internal structures.

Fine filament-like lines emerged. Branching, net-like, sometimes fractal-looking patterns formed, glowing brightly against a dark background. Some droplets looked calm and ordered; others appeared restless. No two droplets looked the same.

From a physical standpoint, these patterns are being explained by evaporation, surface tension, internal flows, crystallization, etc.

Still, Kröplin was intrigued. He argued that the patterns seemed to vary depending on the source and treatment of the water.

From this, he proposed that the patterns were not random, but responsive to environmental conditions. He went further, suggesting that water might reflect a kind of “information” about what it had encountered, including human intention.

Scientifically speaking, this is where observation becomes interpretation.

The images themselves are real and reproducible.

The claim that they encode semantic or intentional information is currently seen as speculative and makes this research sit outside peer-reviewed consensus.

Yet, dismissing the work entirely would also miss something important.

Be curious

History reminds us that scientific understanding evolves. Ideas once considered fringe or simply wrong have later been revised as tools and perspectives changed. We now smile at medical and epidemiological theories from two centuries ago, confident in our progress. It is not unreasonable to assume that some of our current certainties will one day be viewed the same way.

Kröplin’s contribution, then, may not lie in definitive answers, but in the quality of the question he asks: what happens when we truly pay attention to water, not only as a chemical compound, but as a dynamic participant in its environment?

His work is documented most fully in the book Welt im Tropfen (World in a Drop), which brings together more than fifteen years of observations and reflections, and in the documentary Water: The Great Mystery (2006).

For those on an upstream path, hold wonder and rigor at the same time.

Because the story of water and our relationship to it, may not yet be finished.

Be curious.

Stay engaged.

Have fun.

Healthy water is not only about theory. It is also about daily choices.

Gold-star rituals: if water has been stagnant in your pipes for more than 4 hours, let the tap run for about 30 seconds. Don’t drink from the tap immediately. Let the water rest briefly in a jug. Chlorine evaporates. Small practices. Meaningful difference.

Before you filter your water, filter your lifestyle and mindset.

Hazard-based thinking asks: Is this substance fundamentally problematic?
Risk-based thinking asks: How much exposure is acceptable under ideal conditions?

A substance can be hazardous even if everyday exposure appears low-risk. Hazard-based regulation looks upstream and asks the harder question: If something is inherently harmful, do we want it in daily use at all? Risk-based thinking assumes perfect use, perfect limits, and perfect compliance—conditions that rarely exist at home.

That’s why hazard-based regulation is the wiser approach. It accepts uncertainty and acts early.

A current cosmetics example:
TPO (Trimethylbenzoyl diphenylphosphine oxide), used for years in gel nail polish, has been banned in the EU as of September 1, 2025. Classified as toxic to reproduction (CMR 1B), it can no longer be manufactured, sold, or used. The UK is expected to follow. Rethink that gel manicure.

The takeaway? Regulation often catches up after long periods of normal use, once better data emerges.

Do a cosmetic audit. Don’t just ask is this allowed? Ask is this healthy?

I don’t want water that’s merely “safe.” I want healthy water. And so do you.
