Common Causes of Water Odors

Chlorine:
- Used in municipal water systems to kill bacteria, viruses, and parasites.
- Excess chlorine can leave a swimming pool-like smell.

Rotten Egg Smell:
- Caused by dimethyl disulfide, produced by microorganisms in oxygen-poor environments.
- Found in soil and natural water sources.

Musty or Earthy Aroma:
- Linked to compounds like geosmin and 2-methylisoborneol, released by algae.
- Odor may be more pronounced in late summer when algae bloom and die.

Metallic Taste:
- Often from ferrous sulfate, a water-soluble form of iron in groundwater, common with well water.

How Experts Do Water Filter Testing

• Filters are tested by professional tasters to assess how well they neutralize odors and flavors like chlorine, rotten food, damp soil, and metallic tastes.
• Test Process:
• Pure spring water is spiked with specific odor-causing compounds.
• Filtered water is blind-tasted by 8–12 tasters who rate it for aroma and taste against pure water on a 0–10 scale (0 = pure spring water).
