Groundwater quality deterioration and overexploitation constitute two critical environmental issues worldwide. In this study, with the aim to achieve a groundwater sustainability purpose, a preliminary hydrogeochemical survey is conducted in the Flamouria basin, Pella prefecture, Northern Greece using available and collected data. For this purpose, chemical analyses of groundwater, springs, and surface water were collected and analyzed with three electrical resistivity tomographies (ERTs). A Groundwater Quality Index (GQI), along with a nitrate susceptibility assessment is applied within the porous aquifer. The water quality analysis along with GQI application showed excellent water quality for potable and irrigation use however highlighted future issue for irrigation utilization as the high alkalinity and total dissolved solid (TDS)could generate excessive soil salinization. Moreover, the application of a methodology for the identification of “Nitrate Vulnerable Zone” called the Protection from Natural and Anthropogenic sources (PNA) highlighted the natural susceptibility to nitrate pollution of the porous aquifer, especially in the central part of the area where most agricultural activity is localized. The work further confirmed how the proposed elaboration could represent an easy and widely applicable hydrological assessment where there is also limited data available.

埃德萨（希腊北部）弗拉穆里亚盆地的水文地质和水化学状况评估

地下水质量恶化和过度开发是全球范围内的两个关键环境问题。在这项研究中，为了实现地下水的可持续发展目的，使用可用的和收集的数据在希腊北部佩拉州的弗拉穆里亚盆地进行了初步的水文地球化学调查。为此，收集了地下水，泉水和地表水的化学分析结果，并使用三种电阻层析成像（ERT）进行了分析。在多孔含水层中应用地下水质量指数（GQI）以及硝酸盐敏感性评估。水质分析以及GQI的应用显示出饮用水和灌溉用水的优良水质，但是由于高碱度和总溶解固体（TDS）可能导致土壤盐渍化，因此突出了灌溉利用的未来问题。此外，应用一种识别“硝酸盐脆弱区”的方法（称为天然和人为源保护（PNA））强调了多孔含水层对硝酸盐污染的自然易感性，特别是在大多数农业地区的中部地区。活动已本地化。这项工作进一步证实了拟议的拟订工作如何能在缺乏可用数据的情况下代表一种容易且广泛适用的水文评估。应用一种称为“免受自然和人为污染源”（PNA）的“硝酸盐脆弱区”的识别方法的应用，突显了多孔含水层对硝酸盐污染的自然敏感性，特别是在农业活动最为活跃的地区中部本地化。这项工作进一步证实了拟议的拟订工作如何能在缺乏可用数据的情况下代表一种容易和广泛适用的水文评估。运用一种识别“硝酸盐脆弱区”的方法（称为自然和人为源保护（PNA））的应用，突出了多孔含水层对硝酸盐污染的自然敏感性，特别是在农业活动最为集中的地区的中部地区本地化。这项工作进一步证实了拟议的拟订工作如何能在缺乏可用数据的情况下代表一种容易和广泛适用的水文评估。
