|Title||Vulnerability of Gaza Aquifer to Pesticides Contamination Using GIS-DRASTIC Index|
Vulnerability ofGazaaquifer for pesticides contamination has been examined using GIS based DRASTIC model. All physiographic and hydro-geologic data collected from concerned agencies have been carefully studied, arranged, tabulated in such format accepted by the GIS model, and utilized to produce the vulnerability to pesticides maps. As a result of DRASTIC model, 5,768 hectares (16%) of Gaza aquifer were found under severe vulnerability. 20,607 hectares (57%) were under high vulnerability. 8,973 hectares (25%) are under moderate vulnerability. The remaining small part which is 652 hectares (2%) were under low vulnerability. The most vulnerable area inGazastrip is North and parts ofGazaarea, so much care and monitoring have to be applied for the land use management. South area and east part of middle area were found under high vulnerability. The study shows that the man activities on the land can exert offensive impact on the level of contamination. On the other hand, if the provision of pest management has been followed, the vulnerable areas could be less contaminated.
