In Siwa Oasis there are many wells and we want to know whether the water is renewable and what is the source of the water : from the Nile or the water coming from the rain on the Sudan or is non-renewable water from ancient geological times
Question: In Siwa Oasis there are many wells and we want to know whether the water is renewable and what is the source of the water.
The water is renewable.
Now, the source: Groundwater mainly comes from following sources:
Meteoric Water - Recent water, main source of groundwater and is received in the form of rain and snow.
Connate water or fossil water - Exists in pores and cavities of sedimentary rocks of seas and lakes.
Juvenile water - It is also referred to as magmatic water. This water forms after condensation of vapour as a result of volcanic action at the time of entering hot rocks. It usually has high mineral content.
Oceanic water - It is common in the coastal areas where ocean water seeps horizontally into the ground from the ocean.
The determination of age of groundwater may indicate its source. The radiosotopes for example hydrogen-3 (tritium) and carbon-14 are found to be most useful in age-dating. The physicochemical characteristics also give some clues on the origin.

It is undoubtedly renewable...otherwise all wells will dry up permanently...

But, I need to know the source
Hi Sibra
I would think hydrogen and oxygen isotopes would be a useful method, e.g. see:
https://www.researchgate.net/profile/Van_Ryan_Kristopher_Galarpe/post/What_specific_radioactive_isotopes_in_surface_water_may_indicate_contamination_pollution/attachment/59d7936bf3ec044767de8cee/AS:546360865640448@1507273989463/download/HydroIsotop.pdf
Question is if it is renewable (ie recharged) in timescale relevant to water extraction rate.
Best wishes

Mostly, its rainwater seeped into ground water , and wells are the part of ground water connected to active acquifer...which act as perennial source of water in most renewable form...
It was renewable .To now the source you can measure ECw during rainfall period and dry season ,if you notice that ECw values increased in dry season then you must conclude that the source was rainwater seek to ground water,if it still close to the reading value of rainy seasons ,then you can coclude that the river is the major source of this water.

Perfectly explained by Dr. Asit Kumar. There are several sources. In majority cases it is renewable from rainwater. But there are aquifers with groundwater trapped in them with an age of more than 1000 years. As already explained application of isotope technique, using Tritium (source of groundwater) and carbon (age of groundwater) methods will give the source and age of groundwater.
Wells,
The evolution of the groundwater which solve faced problem is similar to case study in the attached article.

Mr. Bayan,
Your Paper - I have read the abstract. Good work. Later, I will see the details. Thanks
