There are many natural springs throughout Palestine, which have traditionally been used for domestic purposes and irrigation. Spring water still counts for a significant amount of Palestinian water consumption. But the amount of water available to Palestinians via springs is steadily declining due to deep Israeli wells, confiscation by illegal colonizers and environmental factors.
Each Friday the people of Nabi Saleh march non-violently to try to reach their spring acquired in 2010 by settlers from Halamish with the support of the Israeli army.
From the World Bank:
Israeli wells in the West Bank have dried up local Palestinian wells and springs
*At Bardala, in the North Eastern corner of Tubas Governorate, eight Palestinian wells were constructed before 1967 for domestic and agricultural purposes, with depths ranging from 30 to 65 metres. After the 1967 war, Israel constructed two deep wells (Bardala 1 in 1968 and Bardala 2 in 1979) a few hundred metres from the Palestinian wells. The water level in the Palestinian wells dropped at the rate of 2 metres a year, and salinity increased. Now the Palestinian wells are dry, as are most of the local springs used by Palestinian consumers for domestic and agricultural purposes.
*At Fasayil in Jericho governorate, Israel has drilled six production wells. The yield of the single Palestinian well in the area has fallen to zero, and the formerly abundant local springs have dried up.
*At Auja, the very productive Auja spring, which formerly discharged up to 9 MCM a year, has dried up for months on end through the action of five nearby Israeli production wells. A formerly water- abundant village is now buying back water from nearby settlements.
