Vermont Public Community Water Supply Data

These tables are made available as part of a collaboration between the Environmental Public Health Tracking (Tracking) Program at the Health Department and The Drinking Water and Groundwater Protection Division at the Department of Environmental Conservation (DEC). To see visualizations of these data, visit the Tracking Program page on the Health Department website. There is also more detailed metadata documentation on the Health Department website. Annual Results Table This table contains water quality testing results for arsenic, atrazine, combined radium (-226 & -228), combined uranium, di(2-Ethylhexyl) phthalate (DEPH), nitrate, tetrachloroethylene (PCE), trichloroethylene (TCE), total trihalomethane (TTHM), and five haloacetic acids (HAA5) for public water systems in Vermont. Data provided include the mean and maximum concentration for each analyte categorized by: not detected, less than or equal to the maximum contaminant level, or greater than the maximum contaminant level. Users can see the number of water systems and the number of people served by those water systems that fell into each of the above categories. Data are available 1999-2024. Public Water Use Table This table contains information about the total number of public water system connections and the total population served by those connections in Vermont from 1999-2025. System Level Drinking Water Data This table contains water quality testing results for arsenic, atrazine, combined radium (-226 & -228), uranium, di(2-Ethylhexyl) phthalate (DEPH), nitrate, tetrachloroethylene (PCE), trichloroethylene (TCE), total trihalomethane (TTHM), and five haloacetic acids (HAA5) for public water systems in Vermont. Data are available for each public water system and include annual measures for the mean and maximum concentration for each contaminant along with interpretation based on whether the result is: not detected, less than or equal to the maximum contaminant level (MCL), or greater than the MCL. Data are available from 1999-2025.本批数据集表格由卫生部门环境公共卫生追踪（Environmental Public Health Tracking）项目与环境保护部（Department of Environmental Conservation, DEC）饮用水与地下水保护司合作发布。如需查看数据可视化成果，请访问卫生部门官网的追踪项目页面；该官网还提供更详细的元数据文档。 年度结果表 本表格收录佛蒙特州公共供水系统的多项水质检测结果，检测指标包括砷（arsenic）、阿特拉津（atrazine）、复合镭（-226与-228）（combined radium (-226 & -228)）、复合铀（combined uranium）、邻苯二甲酸二(2-乙基己基)酯（di(2-Ethylhexyl) phthalate, DEPH）、硝酸盐（nitrate）、四氯乙烯（tetrachloroethylene, PCE）、三氯乙烯（trichloroethylene, TCE）、总三卤甲烷（total trihalomethane, TTHM）以及5种卤代乙酸（five haloacetic acids, HAA5）。数据按未检出、浓度小于等于最大污染物限值（maximum contaminant level, MCL）、浓度大于最大污染物限值三类，对各分析物的平均浓度与最大浓度进行分类呈现。使用者可查询落入上述各类别的供水系统数量，以及对应供水系统服务的总人口数。本数据集覆盖1999年至2024年。 公共供水使用表 本表格收录1999年至2025年佛蒙特州公共供水系统的总连接户数，以及该类连接所服务的总人口数相关信息。 系统级饮用水数据表 本表格收录佛蒙特州各公共供水系统的多项水质检测结果，检测指标与年度结果表一致，包括砷（arsenic）、阿特拉津（atrazine）、复合镭（-226与-228）（combined radium (-226 & -228)）、铀（uranium）、邻苯二甲酸二(2-乙基己基)酯（di(2-Ethylhexyl) phthalate, DEPH）、硝酸盐（nitrate）、四氯乙烯（tetrachloroethylene, PCE）、三氯乙烯（trichloroethylene, TCE）、总三卤甲烷（total trihalomethane, TTHM）以及5种卤代乙酸（five haloacetic acids, HAA5）。本数据集以单个公共供水系统为统计单位，包含各污染物的年度平均浓度与最大浓度，以及基于检测结果的判定解读：未检出、浓度小于等于最大污染物限值（MCL）或浓度大于MCL。本数据集覆盖1999年至2025年。
