马萨诸塞州威克菲尔德镇的水利部为大约25000人提供饮用水，其饮用水的15%来自水晶湖（其余来自马萨诸塞州水资源管理局）。水晶湖位于韦克菲尔德的西南部，它的分水岭在韦克菲尔德和邻近的斯通汉姆镇占地约600英亩。在水晶湖流域内，主要的土地利用以中等密度住宅和一些商业和工业活动为特征。1998年，马萨诸塞州环境保护部（MADEP）根据州水源评估和保护计划提供资金，以加强对水晶湖作为饮用水源的评估和保护。作为评估工作的一部分，将雨水径流和通往水晶湖的污水管溢流（SSO）的管理确定为改善水质的最高优先事项。 深入研究了湖周围不同区域通过多个雨水排放口排放的雨水。此外，项目团队还审查了斯通汉姆镇水晶湖附近的污水泵站的运行情况，并提出了防止未来SSO事件的建议。一轮针对当地居民、企业和镇官员的外联活动正在进行，以概述雨水和SSO问题，并促进水晶湖水质的更好环境管理。包括数字。

The Water Department of the Town of Wakefield, Massachusetts provides drinking water to about 25,000 people and it receives approximately 15% of its drinking water from Crystal Lake (with the remainder from the Massachusetts Water Resources Authority). Crystal Lake is located in the southwestern part of Wakefield, and its watershed encompasses about 600 acres in Wakefield and the neighboring Town of Stoneham. Within the Crystal Lake watershed, the dominant land use is characterized by medium density residential with some commercial and industrial activities. In 1998, the Massachusetts Department of Environmental Protection (MADEP) provided funding under the State Source Water Assessment and Protection Program to enhance the assessment and protection of Crystal Lake as a source of drinking water. As a part of the assessment effort, the management of storm water runoff and sanitary sewer overflow (SSO) to Crystal Lake were identified as the highest priorities to improve water quality. An in-depth study of the storm water draining from various areas around the lake through a number of storm water discharge outlets was conducted. In addition, the project team reviewed the operation of a sewer pump station located adjacent to Crystal Lake, in the Town of Stoneham, and provided recommendations to prevent future SSO events. A round of outreach activities for local residents, businesses, and town officials is underway to outline storm water and SSO issues and to promote better environmental management of Crystal Lake's water quality.
