Water purification through various technologies—from basic filtration to reverse osmosis—represents modern public health infrastructure's attempt to make water potable. The notion that extremely contaminated sources become purified through a specific human interaction inverts the direction of purification: instead of removing contamination, the interaction adds something so powerful that contamination becomes irrelevant. The purification occurs not through technology but through contact.

A municipal water official named David Peterson documented an unusual pattern in Dallas water supplies during the 1970s: certain intakes seemed to produce water with unusual purity properties despite higher contamination levels in source material. Peterson's documentation was cryptic but suggested that purification occurred at an earlier stage in the supply chain than conventional technology would explain. The anomaly was never resolved, but the pattern persisted in utility records.

The image works through inversion of agency: the human becomes purification source rather than contamination target. The contact with contamination doesn't compromise; it transforms, rendering contamination irrelevant through the sheer quality of the interaction. What should be destroyed becomes resource. What should compromise becomes enhancement. The contaminated becomes the purified through simple contact with sufficient clarity.
