本研究的目的是通过在巴勒斯坦加沙地带进行为期一年的监测，评估生活用水的理化和微生物质量。水样取自雨水灌溉的蓄水池、供水网络的地下水和脱盐水。就某些化学参数而言，如硝酸盐，所有来源的水样中有很大比例超过了巴勒斯坦标准机构和世界卫生组织（卫生组织）的限度。总溶解固体（TDS）读数不符合大多数样本的地下水和水从雨养水库。但TDS质量在脱盐水中要好得多。就微生物质量而言，在大多数水样中，总大肠菌群和粪便大肠菌群的不符合比例很高，这也反映在加沙地带水传播疾病的高发病率上。该研究表明，脱盐水的质量具有明显的优势，但也需要在脱盐厂采用更好的做法（维护和前后处理）。(C)2009年由Elsevier B.V.出版
The aim of this study was to assess the physiochemical and microbiological quality of the domestic water through one-year long Surveillance in Gaza Strip, Palestine. Water samples were taken from rain-fed cisterns, groundwater from the water network, and desalinated water. For certain chemical parameters, such as nitrate, a high percentage of water samples from all sources exceeded the limits of the Palestinian Standard Institution and the World Health Organization (WHO). Total dissolved solid (TDS) readings were noncompliant for most samples from groundwater and water from rain-fed cisterns. but the TDS quality was far better in desalinated water. As far as microbiological quality is concerned, high percentages of noncompliance were observed for total Coliform and fecal Coliform in most water samples, which was also reflected by the high incidence of water-borne diseases in Gaza Strip. The study reveals a clear superiority of quality for desalinated water, but also the need to adopt better practices (maintenance and pre- and post-treatment) in the desalination plants.
