Assessment of Environmental Problems
Water Balance equation reveal water surplus, but wells and springs running dry, indicating poor management and monitoring.
Water Quality is worse than poor, it is TOXIC.
BUT, based on Physical Environment, solutions to these problems exist.
Remediation Proposalsi. Environmental Remediations
a. Water and Soil monitoring and sampling; b. Extract toxic groundwater; c. Air pumping wells
ii. Engineering Effortsa. Recharge areas; b. Dams; c. Reservoirs; d. Wastewater treatment
factility
iii. Palestinian Management and Controla. Laws promoting beneficial and sustainable use; b. Create
agency to act as watchdog; c. Develop water projects
iv. Introduce Efficient Irrigation Techniquesa. Drip vs. open canal irrigation; b. Friendly fertilizers
v. Teaching and bringing awareness
vi. Drill new wells in high quality deep aquifer
(NOT EXHAUSTIVE)
Some RealitiesI. 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.
