Summary This hosted table contains the full monitoring dataset for the indicated Watershed Watch season, including all measured parameters. Overview The URI Watershed Watch Program produces quality data for a broad range of parameters for monitoring sites statewide. Produced using well established methods, and processed in state certified laboratories, this information is used by the Rhode Island Department of Environmental Management for assessing the State’s waters, as well as by municipal governments, associations, consulting firms and residents for more effective management of local resources. Measured Parameters Water Clarity (Secchi depth – lakes and ponds) Chlorophyll (lakes and ponds, some rivers) Water Depth Total and Dissolved Phosphorus Water Temperature Total, Nitrate-, and Ammonium- Nitrogen Dissolved Oxygen (deep sites/streams) Chloride pH Fecal coliform and enterococci bacteria Alkalinity Salinity (estuarine sites) Data Quality The URI Watershed Watch program incorporates procedures and protocols recommended and approved by national organizations to ensure that monitoring results accurately reflect the conditions of the sampled water bodies. Results from laboratory staff and volunteers are regularly checked against known standards and quality control samples. State-of-the-art research grade instruments are generally used, permitting high resolution and excellent detection limits. Specific methods of analyses and limits of detection are available upon request. Visit URI Watershed Watch Program page for more about the parameters monitored. What is monitored?### 数据集概述 本托管表格包含指定「流域监测计划（Watershed Watch）」季度的完整监测数据集，涵盖所有实测参数。 ### 项目概况 罗德岛大学流域监测计划（URI Watershed Watch Program）为全州范围内的监测点位采集多类别参数的高质量数据。本数据集采用经过实践验证的成熟分析方法获取，并经州级认证实验室完成分析处理，其数据可用于罗德岛州环境管理部开展州内水体评估工作，同时也可供市政当局、行业协会、咨询企业及居民使用，以更高效地开展本地资源管理。 ### 实测参数 1. 水体透明度（塞氏深度，Secchi depth——适用于湖泊与池塘） 2. 叶绿素含量（适用于湖泊、池塘及部分河流） 3. 水深 4. 总磷与溶解性磷 5. 水温 6. 总氮、硝酸盐氮与氨氮 7. 溶解氧（适用于深水区点位/溪流） 8. 氯化物 9. pH值 10. 粪大肠菌群与肠球菌 11. 碱度 12. 盐度（适用于河口点位） ### 数据质量控制 罗德岛大学流域监测计划采用全国性权威机构推荐并批准的流程与规范，以确保监测结果能够准确反映采样水体的实际状况。实验室专职人员与志愿监测人员的检测结果会定期与已知标准物质及质量控制样品进行比对核验。项目通常采用顶尖的科研级仪器，可实现高分辨率监测与优异的检出限。具体分析方法与检出限可按需索取。如需了解更多监测参数相关信息，请访问罗德岛大学流域监测计划（URI Watershed Watch Program）官方页面。 **监测内容为何？**
