Water quality in Lake Constance, Thur and Murg

The Office for the Environment is investigating at regular intervals, the larger waters on their chemical and biological water quality. For this purpose, the Thurgau was divided into three catchment areas. divided. One catchment area (DC) is examined per year. Each EZ will Therefore, every three years, the catchment areas are examined. Lake Constance, Thur and MurgInformation on limit values and the assessment of water quality can be taken from the methods of investigation and assessment of watercourses. General information:The nitrite and ammonium content is It's about normalized values. The ammonium content is normalized to the limit value for Water temperatures >10°C. The nitrite content is normalized to the limit value for chloride contents < 10 mg/l.The declared values represent the 90% quantile of the 12 measuring points per year.Data source: Office for the Environment Canton of Thurgau图尔高州环境办公室正定期针对辖区内较大水域开展化学与生物水质监测工作。为此，该州被划分为三个汇水区（catchment area），每年监测一个汇水区（DC），由此所有汇水区每三年完成一轮全面监测。本次监测涵盖康斯坦茨湖（Lake Constance）、图尔河（Thur）与穆尔格河（Murg）三个汇水区。有关限值标准及水质评价的相关信息，可参考《河道调查与评价方法》获取。 通用说明：本次监测所采用的亚硝酸盐与铵盐含量数据均为归一化值。其中，铵盐含量以水温高于10℃时的限值为基准进行归一化处理；亚硝酸盐含量则以氯化物浓度低于10mg/L时的限值为基准完成归一化处理。所公布的监测数值为每年12个监测点位数据的90%分位数。 数据来源：图尔高州环境办公室（Office for the Environment Canton of Thurgau）
