There must be some simple scientific explanation for this..could be because of river water mixing with the sea water at Mahim and turning it less salty..what's amazing is the ignorance of the inhabitants of a metropolis like Mumbai, that too in the 21st century!! Surprising that people are gullible enough to believe in 'miracles' in the 21st century!! No wonder the world thinks we're a nation of fakirs and snake-charmers!
