Al-Ahsa Water Springs

Al-ahsa water spring is a flowing water spring, as described in the book Oasis of Al-Ahsa, by author Federico S. Vidal, which he wrote in 1952 when he was working in the Arabian-American Oil Company (ARAMCO) and he submitted it to Harvard University as a subject for his doctorate degree thesis in 1964. The estimated number of Al-ahsa springs is between sixty and seventy springs, including four huge springs. They flow individually sometimes, or in groups and it is artesian in its flow. The approximate flow of the spring is about 150 thousand gallons in a minute. The springs vary in depth significantly, ranging between 500 feet (150 m) to 600 feet (180 m) and the depth of some of the large springs is just a little off the earth's surface. The water of the spring is warm, the temperature ranges between 80 °F (27 °C) and 90 °F (32 °C), however, some of them are considered as hot springs, with a temperature of over 90 °F (32 °C), and Najim spring counts as one of the hot springs with sulfur water.
