Assessment of Environmental Problems üWater Balance equation reveal water surplus, but wells and springs running dry, indicating poor management and monitoring. üWater Quality is worse than poor, it is TOXIC. BUT, based on Physical Environment, solutions to these problems exist.
Remediation Proposals (NOT EXHAUSTIVE) i. Environmental Remediations i. a. Water and Soil monitoring and sampling; b. Extract toxic groundwater; c. Air pumping wells ii. Engineering Efforts i. a. Recharge areas; b. Dams; c. Reservoirs; d. Wastewater treatment factility iii. Palestinian Management and Control a. Laws promoting beneficial and sustainable use; b. Create agency to act as watchdog; c. Develop water projects iv. Introduce Efficient Irrigation Techniques i. a. Drip vs. open canal irrigation; b. Friendly fertilizers v. Teaching and bringing awareness vi. Drill new wells in high quality deep aquifer
Some Realities I. Israel is unwilling to pass authority of water in the West Bank to the Palestinians, as they control over 80% of all water resources II. Palestinians are unlikely to have an adequately established government with enough financial capital to act implement environmental recommendations III. Israel has not allowed any water projects that increase Palestinian water supply since 1967, and will doubtfully will begin allowing such projects
Conclusions The solution to the many problems discussed above may lie in the use of foreign agencies like USAID to help understand, assess, recommend and implement such projects that bring about the sustainable use and allocation of water throughout the West Bank.
