Bismillahir Rahmanir Raheem
Assalam Alaikum Wa Rahmath Ullahi Wa Barkatahu
ZamZam Water Level is Around 10.6 feet Below The Surface.
It is The Miracle Of Allah That 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 11 minutes.
8,000 liters per second means that 8,000 x 60 = 480,000 liters per minute 480,000 liters per minutes means that 480,000 x 60 = 28.8 Million liters per hour And 28.8 Million liters per hour means that 28,800,000 x 24 = 691.2 Million liters per day. So they pumped 690 Millions liters of ZamZam in 24 hours, but it was re-supplied in 11 minutes only.
There are 2 miracles here, The First that ZamZam was re-filled 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.
ZamZam is an Arabic word, it is the rope / REIN attached to bridle or noseband & it is used / pulled to stop the running animal.
The Saudi Geological Survey 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.
The water level is 3.23 m (10.6 ft) 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.
Zamzam water has no colour or smell, but it has a distinct taste, and its pH is 7.9–8.0, indicating that it is alkaline to some extent and is similar to seawater.
