Abstract
Water is the main component of life. There are many water sources on earth. The most important one is groundwater. Groundwater makes up the largest proportion of fresh water in Palestine, so it is a big responsibility to maintain its quality, to make sure that safe water reaches the users.
At first, we have been studied the quality of the groundwater in some wells of the western aquifer basin, in the governorate of Tulkarm. Our studies have shown that there are high levels of nitrates in the western aquifer basin (above 50 mg/L NO3- which is the limit according to the World Health Organization WHO). Knowing that these high levels cause health problems such as stomach cancer, respiratory problems in adults, and methemoglobinemia in infants. The analysis was done in the laboratory of the Water and Environmental Studies Institute (WESI) at An-Najah National University. The potential reasons for this pollution are due to the excessive use of agricultural fertilizers and sewage leakage from cesspits. After that, conclusions were made and appropriate recommendations were provided to the owners of these wells and to the Union of Palestinian Water Services Providers (UPWSP) to take the necessary actions. One of these recommendations was to construct wastewater collection networks to get rid of cesspits and leakage into the groundwater, and therefore we designed a sewage network using SewerCAD for the town of Attil as an example of network design.
