Massachusetts Department of Conservation and Recreation (DCR): Quabbin Reservoir and Ware River watershed sampling program, 1987-2013

This report is a summary of water quality monitoring results from twenty-four surface water stations established throughout the Quabbin Reservoir and Ware River watersheds and other special investigative samples. The Department of Conservation and Recreation, Division of Water Supply Protection is the state agency charged with the responsibility of managing Quabbin Reservoir and its surrounding natural resources in order to protect, preserve and enhance the environment of the Commonwealth and to assure the availability of pure water to future generations. As part of this effort, the Environmental Quality Section maintains a comprehensive water quality monitoring program to ensure that Quabbin Reservoir and its tributaries meet state water quality standards. As part of this task, the Environmental Quality Section performs the necessary field work, interprets water quality data and prepares reports of findings. This annual summary is intended to meet the needs of the decision lakers, the concerned public and others whose decisions must reflect water quality considerations. Reservoir water quality data collected by the DCR documents consistently reliable source water quality that fully meets the stringent source water quality criteria stipulated under the Surface Water Treatment Rule. Water quality data are collected monthly except during periods of adverse weather and ice conditions in the winter. Three sampling stations that were routinely sampled in 2010 are profiled in Table 5. Figure 4 may be referenced for the specific locations of each sample site.本报告为奎宾水库（Quabbin Reservoir）与韦尔河（Ware River）流域内布设的24个地表水监测站，以及其他专项调查采样的水质监测结果汇总。马萨诸塞州保护与娱乐部（Department of Conservation and Recreation，简称DCR）下属的供水保护处（Division of Water Supply Protection）为州级主管机构，负责奎宾水库及其周边自然资源的管理工作，以保护、维系并改善马萨诸塞州的生态环境，并保障后世可获得纯净饮用水。作为此项工作的一环，环境质量科（Environmental Quality Section）会开展全面的水质监测计划，以确保奎宾水库及其支流符合州级水质标准。在此项任务框架内，环境质量科会完成必要的野外采样工作，解读水质数据，并编制成果报告。本年度汇总报告旨在满足决策者、关注公众以及其他决策需考量水质因素的相关方的需求。保护与娱乐部采集的水库水质数据显示，源水水质始终稳定可靠，完全符合《地表水消毒条例》（Surface Water Treatment Rule）规定的严苛源水水质标准。除冬季恶劣天气及冰封时段外，水质数据均按月采集。表5详细列出了2010年常规监测的3个采样站点；各采样点的具体位置可参考图4。
