The quality and potability of waters of the Tyśmienica River Basin were determined in 2017 at eight measuring stations. The paper presents analyses of the physical and chemical parameters of surface waters of the basin. With regard to suspended solids, pH value, electric conductivity, sulphates, ammonia, chlorides and phosphate, the water was classified as having a very good ecological status. In the case of Kjeldahl nitrogen, the waters were classified as having a good ecological status. In the case of the remaining parameters, i.e. BOD, DO, TOC and COD, the status varied among stations. The values of all the physical and chemical parameters complied with the values for undisturbed conditions. Only ammonia and COD showed significant differences among stations. The WPI values for each measuring point ranged from 0.90 to 1.56, what corresponds to the descriptive indicators of moderately polluted water. The high concentrations of COD and TOC indicate that high-performance treatment processes (category A3) must be used to ensure that the water is suitable for drinking.
2017 年，在泰申尼采河流域的八个测量站确定了该流域水质和可饮用性。本文介绍了流域地表水的物理和化学参数分析。就悬浮固体、pH 值、电导率、硫酸盐、氨、氯化物和磷酸盐而言，水被归类为具有极好的生态状况。就凯氏氮而言，水被归类为具有良好的生态状况。就其余参数，即 BOD、DO、TOC 和 COD 而言，各站之间的状况有所不同。所有物理和化学参数的值都符合未受干扰条件的值。只有氨和 COD 在各站之间存在显著差异。每个测量点的 WPI 值范围为 0.90 至 1.56，这对应于中度污染水的描述性指标。高浓度的 COD 和 TOC 表明，必须使用高性能处理工艺（A3 类）来确保水适合饮用。
