Water quality map of the Saarland 2008

Water quality map of the Saarland (2008) Water quality map according to uniform criteria of the Länderarbeitsgemeinschaft Wasser (LAWA). The data base for this is the water quality register (chemical and biological state of Saarland flowing waters), which is maintained by the State Office for Environmental and Occupational Safety. Material data/attribute information: Flow ID: internal ID Class:Water Gütekclassification Class1 = unloaded to very low load Class2 = low load Class3 = moderately loaded Class4 = critically loaded Class5 = heavily polluted Class6 = very heavily polluted Class7 = excessively polluted Text: Water name萨尔州2008年水质地图 本数据集为依据德国各州水工作组（Länderarbeitsgemeinschaft Wasser, LAWA）统一标准编制的水质地图。其数据基础为由州环境与职业安全办公室维护的萨尔州流动水体化学与生物学状态水质登记库。 材料数据/属性信息如下： - 流动水体ID（Flow ID）：内部标识号 - 分级（Class）：水质分级（Wassergüteklasse），具体分级标准为： Class1 = 未受污染至极低污染负荷 Class2 = 低污染负荷 Class3 = 中度污染负荷 Class4 = 临界污染负荷 Class5 = 重度污染 Class6 = 极重度污染 Class7 = 过度污染 - 文本（Text）：水体名称
