The 2006 Mumbai sweet seawater incident

Geology

This page covers the time residents of Mumbai and Gujarat started drinking from Mahim Creek and Tithal beach because the water suddenly tasted sweet. It is a textbook example of the gap between a geological fluke and the resulting mass hysteria. The cause was a freshwater plume from underground rock formations floating on top of the ocean. I recall a few similar instances where natural anomalies were branded as miracles; it always ends the same way once the data is published. It is a fascinating read for anyone who likes the weird side of hydrology. You might want to look into the related entries on freshwater plumes or the general mechanics of aquifer discharge to see how this actually works.

OP is correct about the data. Salinity readings during these plumes often drop significantly, which explains why the water was physically detectable as fresh.

What if the sweetness wasn't solely due to freshwater? If specific mineral leaching occurred, the taste might have been a warning sign of contamination rather than a sign of purity.

Is it really mass hysteria if the water actually tasted sweet? The taste was a physical reality. The hysteria was the interpretation, not the perception.

You have to consider the actual state of Mumbai's water infrastructure. When people lack reliable municipal supply, drinking from a "miracle" beach is often a survival strategy rather than just a whim.
