Fraser River Long-term Water Quality Monitoring Data

Long-term freshwater quality monitoring data for over 14 sites in the Fraser River Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) and under the Canada-British Columbia Water Quality Monitoring Agreement to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions.

本数据集收录弗雷泽河流域（Fraser River Basin）14个以上监测点位长达15年及更久的长期淡水水质监测数据，监测指标涵盖营养盐、金属、主要离子及其他理化变量。该监测工作由加拿大环境与气候变化部（Environment and Climate Change Canada, ECCC）依据《加拿大-不列颠哥伦比亚省水质监测协议》开展，旨在评估水质现状与长期变化趋势、识别新兴环境问题、制定水质基准，并追踪补救措施与监管决策的实施效果。
