The general profile of the pollution of drinking water, originating from groundwater, by nitrates, chloride and arsenic, in the Prefecture of Thessaloniki, was studied in this project. Samples (tap water) were collected from 52 areas-villages of the Prefecture, during a period of 6 months. The analytical results were related to certain points on the map of the area, thus producing coloured representations of the Prefecture, according to the concentration of the corresponding pollutant. The statistical analysis of the data led to some conclusions concerning the causes of pollution and the relation of the concentrations to certain physico-chemical parameters. Nitrate concentration of samples collected from two specific regions were especially high, sometimes above the highest permitted level. A limited number of samples (13.5%) contained arsenic concentrations above the imminent EC drinking water limit (10 ppb). The majority of the tap water samples, collected from areas along the seashore contained increased concentrations of chloride ions, which is a clear indication of seawater intrusion into the related aquifers.
本项目研究了塞萨洛尼基地区源自地下水的饮用水受硝酸盐、氯化物和砷污染的总体情况。在6个月的时间里，从该地区的52个区域村庄采集了样本（自来水）。分析结果与该地区地图上的某些点相关，从而根据相应污染物的浓度生成该地区的彩色图表。数据的统计分析得出了一些关于污染原因以及浓度与某些物理化学参数关系的结论。从两个特定区域采集的样本中硝酸盐浓度特别高，有时高于最高允许水平。数量有限的样本（13.5%）砷浓度高于欧盟即将出台的饮用水限值（10 ppb）。从沿海地区采集的大多数自来水样本中氯离子浓度增加，这清楚表明海水侵入了相关含水层。
