when ZamZam was pumped continuously for more than 24 hours with a pumping rate
of 8,000 liters per second, water level dropped to almost 44 feet below the
surface, BUT WHEN THE PUMPING WAS
STOPPED, the level immediately elevated again to 13 feet after
8,000 x 60 = 480,000 liters per minute
that 480,000 x 60 = 28.8 Million liters per hour
means that 28,800,000 x 24 = 691.2 Million liters per day
of ZamZam in 24 hours, but it was re-supplied in 11 minutes only.

immediately, & the second is
that Allah Holds the extra-ordinarily powerful Aquifer for not throwing extra
ZamZam out of the well, otherwise the world will SINK. It is the translation of
the word ZamZam, which means Stop !!!!!!!!!!!! Stop !!!!!!!!!!!!!!! said by
Hajirah Alaih As Salaam.

has a “Zamzam Studies and Research Centre” which analyses the technical
properties of the well in detail. Water levels were monitored by hydrograph, which in more recent times has changed to a digital
monitoring system that tracks the water level, electric conductivity, pH, Eh, and temperature.
All of this information is made continuously available via the Internet. Other
wells throughout the valley have also been established, some with digital
recorders, to monitor the response of the local aquifer system.
below the surface. A pumping test at 8,000 litres per second (280 cu ft/s) for
more than a 24 hour period showed a drop in water level from 3.23 m (10.6 ft)
below surface to 12.72 m (41.7 ft) and then to 13.39 m (43.9 ft), after which
the water level stopped receding. When pumping stopped, the water level
recovered to 3.9 m (13 ft) below surface only 11 minutes later. This data shows
that the aquifer feeding the well seems to recharge from rock fractures in
neighbouring mountains around Mecca.

alkaline to some extent and is similar to seawater.
