River Water Quality Monitoring 1990 to 2018

<div style='text-align:left;'><div><div><p><span>This table provides the raw data from river monitoring sites including Water Framework Directive monitoring sites. It should be noted that, as the data set is in its raw state, it cannot be used to provide a status without processing. The data set does not show Limits of Detection or Limit of Quantitation which would require a value to be treated as a half value for WFD calculation. In addition both altitude and alkalinity affect status calculations for some parameters. The data set may contain results which are erroneous due to typos, sampling error or contamination, such data points are usually several orders or magnitude above expected values.</span></p><p><span>This is the first in a series of water data sets being made available as Open Data.

The Water (Amendment) (Northern Ireland) (EU Exit) Regulations 2019 ensures that the Water Framework Directive (WFD) (as transposed) and the various supporting pieces of water legislation continue to operate here after 1 January 2021. The regulation encourage the active involvement of interested parties and the general public.</span></p><p><span>The regulations set out the requirement to achieve 'Good Ecological Status' and 'Good Chemical Status' for all ground and surface waters (rivers, lakes, transitional waters, and coastal waters) within Northern Ireland.</span></p><ul><li><p><span>Surface waters are assessed according to the following criteria:</span></p></li><li><p><span>Biological quality (fish, invertebrates, flora)</span></p></li><li><p><span>Hydromorphological</span></p></li><li><p><span>Physico-chemical properties like temperature, oxygenation and nutrient conditions.</span></p></li><li><p><span>Chemical quality assessed against environmental quality standards for specific pollutants and priority substances.</span></p></li></ul><p><span>The following physio-chemical and chemical parameters are included in the data set:</span></p><ul><li><p><span>ALK (mg/l) </span><span>- </span><span>Alkalinity</span></p></li><li><p><span>BOD</span><span><span>(mg/l) </span><span>- </span><span>Biochemical oxygen Demand</span></span></p></li><li><p><span>COND (uS/cm) </span><span>- </span><span>Conductivity</span></p></li><li><p><span>CUSOL1</span><span><span>(mg/l) </span><span>- </span><span>Copper Dissolved</span></span></p></li><li><p><span>CUSOL2</span><span><span>(ug/l) </span><span>- </span><span>Copper Dissolved</span></span></p></li><li><p><span>DO</span><span><span>(mg/l</span><span>) - </span><span>Dissolved Oxygen</span></span></p></li><li><p><span>FESOL1</span><span><span>(ug/l) </span><span>- </span><span>Iron Dissolved</span></span></p></li><li><p><span>NO3-</span><span>N </span><span>(mg/l) </span><span>- </span><span>Nitrate</span></p></li><li><p><span>NO2-N</span><span><span>(mg/l) </span><span>- </span><span>Nitrite</span></span></p></li><li><p><span>NH4-N</span><span><span>(mg/l) </span><span>- </span><span>Ammonia</span></span></p></li><li><p><span>PH</span><span><span>pH </span><span>- </span><span>pH</span></span></p></li><li><p><span>P(SOL)</span><span><span>(mg/l) </span><span>- </span><span>Phosphorus Soluble</span></span></p></li><li><p><span>SS</span><span><span>(mg/l) </span><span>- </span><span>Suspended solids</span></span></p></li><li><p><span>ZN SOL</span><span><span>(ug/l</span><span>) - </span><span>Zinc Dissolved</span></span></p></li></ul><p></p></div></div></div>本表格收录了来自河流监测站点的原始监测数据，其中包含水框架指令（Water Framework Directive, WFD）监测站点的相关数据。需注意，本数据集处于未处理的原始状态，未经加工无法直接用于水体状态评估。本数据集未包含检测限（Limits of Detection）与定量限（Limit of Quantitation）相关信息，而在水框架指令的计算中，此类限值对应的数值需按半值进行处理。此外，海拔与碱度会对部分参数的水体状态评估结果产生影响。本数据集可能包含因笔误、采样误差或污染导致的异常结果，此类数据点通常较预期数值高出数个数量级。 本数据集为首批公开的水体数据系列之一，其余数据集可通过邮箱[e-mail]申请获取。 欧盟《水框架指令（2000/60/EC）》已通过《2017年水环境（水框架指令）条例（北爱尔兰）》转化为北爱尔兰本地法规。《2019年水（修正案）（北爱尔兰）（欧盟脱欧）条例》确保了经转化的《水框架指令》（WFD）及各类配套水法规在2021年1月1日后仍可在北爱尔兰境内施行。上述法规鼓励利益相关方及社会公众积极参与相关工作。 该法规要求北爱尔兰境内所有地下水及地表水（河流、湖泊、过渡水域及近岸海域）均需达到"良好生态状态"与"良好化学状态"标准。 地表水依据以下标准开展评估： - 生物质量（鱼类、无脊椎动物、水生植物） - 水文形态学指标 - 物理化学性质，包括温度、溶解氧状况及营养盐条件 - 化学质量，依据特定污染物及优先管控物质的环境质量标准进行评估。 本数据集涵盖以下物理化学与化学参数： - ALK（mg/l）：碱度（Alkalinity） - BOD（mg/l）：生化需氧量（Biochemical Oxygen Demand） - COND（μS/cm）：电导率（Conductivity） - CUSOL1（mg/l）：溶解态铜（Copper Dissolved） - CUSOL2（μg/l）：溶解态铜（Copper Dissolved） - DO（mg/l）：溶解氧（Dissolved Oxygen） - FESOL1（μg/l）：溶解态铁（Iron Dissolved） - NO3-N（mg/l）：硝酸盐（Nitrate） - NO2-N（mg/l）：亚硝酸盐（Nitrite） - NH4-N（mg/l）：氨氮（Ammonia） - pH：酸碱度（pH） - P(SOL)（mg/l）：可溶性磷（Phosphorus Soluble） - SS（mg/l）：悬浮固体（Suspended Solids） - ZN SOL（μg/l）：溶解态锌（Zinc Dissolved）
