Says water below 100 feet is highly saline and non-potable

In a recent move, Brihanmumbai Municipal Corporation (BMC) has decided to restrict the depth of borewells and tubewells in the city to 100 feet. This comes after the civic body asked the Central Water and Power Research Station (CWPRS), Pune, to
examine the underground water in the city.

The primary report submitted by CWPRS revealed that the underground water had high saline content and was, therefore, not fit for drinking.
