Drama盆地是希腊北部一个典型的山地间盆地(2,300公里)，充斥着含有泥炭/褐煤煤层的碎屑和湖泊沉积。在盆地的西南部(菲利皮子盆地)，泥炭几乎一直堆积到现在。测定了该盆地20个地表和浅层地下水样品的电导率和pH值，以及主要离子和微量元素的含量。水的组成反映了整个盆地碳酸盐岩的优势。泥炭氧化和矿化作用导致菲利皮次盆地地表水的元素丰度较差，这些水来自有机和无机泥炭馏分。人为活动(废水流出物和垃圾场)增加了锰、磷、硼和溴的浓度。在一些地方，只有锰超过了EC推荐的标准(50杯/L)。Na+和Cl-含量也略有增加。改善点污染源管理措施应是保障Drama盆地水资源可持续利用的优先事项。
The Drama basin is a typical intermontane basin (2,300 km(2)) in northern Greece filled with detrital and lacustrine sediments containing peat/lignite seams. In the southwestern part of the basin (Philippi sub-basin) peat accumulated practically until the present. Specific conductivity and pH, as well as contents of major ions and trace elements have been determined in 20 surface and shallow groundwater samples collected across the basin. Water composition reflects the dominance of carbonate rocks in the whole basin. Peat oxidation an mineralization contribute to poor element enrichment of the Philippi sub-basin surface water derived from both the organic and inorganic peat fractions. Anthropogenic activities (waste water effluents and rubbish dumps) increase Mn, P, B, and Br concentrations. Only Mn exceeds EC recommendations (50 mug/l) in some places. There is also a slight increase in Na+ and Cl- contents. Improving measures in the management of point pollution sources should be a priority to warrant the sustainable exploitation of water resources in the Drama basin.
