Due to a computer error there were some OA serial water heaters manufactured. Month of manufacture can be determined by using the 2nd letter digit. “It’s an additional source and instead of drilling very deep wells, which is very expensive, the won’t have to. Determining the age of water sources helps in those calculations. Style 1: KJ -1000130 Year of manufacture can be determined by using the 1st letter digit.

“When we quantify the amount of water in the shallow aquifer, we have to consider the water coming up from the deeper aquifer,” said Sherif. Sherif said that finding this natural discharge from the deep aquifers through these faults to the shallower aquifers is important for the developmental plan for the area. The water coming up from the deeper aquifer likely ended up there when the climate was much wetter - as far back as a million years ago - with abundant rainfall that caused a lot of water to seep into the ground and collect in the very thick, porous sandstone. When you have clogged sinks, bathtubs or toilets that overflow, its obvious that youre in.

Sturchio said that while the water is probably not actually 200,000 years old, the fact that it appears that way shows that older water from the Nubian Aquifer comes up along faults in the rocks and mixes in with the shallow water, carrying some of the older chlorine with it. New-Old Water Spots Tips by Water Damage Restoration Experts. “But in some of these aquifers, Mahmoud found water that’s apparently 200,000 years old.” “In the shallow aquifers you would expect young water, perhaps 50-100 years old, because it’s coming down as rain and flowing out towards the Nile Valley,” said Sturchio. Sturchio, professor and chair of the Department of Geological Sciences in UD’s College of Earth, Ocean and Environment, said that the Eastern Desert is interesting because while it is still dry and arid, it gets more rain than the Western Desert of Egypt.īecause of this rain, the researchers were curious to see if the groundwater in the Eastern Desert might be generally younger than the water found in the Western Desert, but were surprised by their findings. The researchers used the long-lived radioactive isotope chlorine-36 to estimate the age of the groundwaters this isotope forms in the atmosphere and travels to the earth and has a half-life of 300,000 years. To measure the age and origin of the groundwater, 29 samples were collected from different wells during several field expeditions in Egypt. Due to a computer error there were some OA serial water heaters manufactured. While groundwater provides only seven percent of the water demand in Egypt, Egyptian water authorities have recently given renewed attention to increasing its exploitation, especially in eastern Egypt, to mitigate the growing water stress and to accommodate agriculture projects.
