Water Quality - Integrated List Non-Attaining Streams

This layer shows only non-attaining segments of the Integrated List. The Streams Integrated List represents stream assessments in an integrated format for the Clean Water Act Section 305(b) reporting and Section 303(d) listing. Streams are bodies of flowing surface water that collectively form a network that drains a catchment or basin. PA DEP protects 4 stream water uses: aquatic life, fish consumption, potable water supply, and recreation. The 305(b) layers represents stream segments that have been evaluated for attainment of those uses. If a stream segment is not attaining any one of its 4 uses, it is considered impaired. · Aquatic Life use attainment - The integrity reflected in any component of the biological community. (i.e. fish or fish food organisms) · Fish Consumption use attainment - The risk posed to people by the consumption of aquatic organisms (ex. fish, shellfish, frogs, turtles, crayfish, etc.) · Recreational use attainment - The risk associated with human recreation activities in or on a water body. (i.e. exposure to bacteria and other disease causing organisms through water contact recreation like swimming or water skiing) · Potable Water Supply use attainment - The risk posed to people by the ingestion of drinking water Segments that have appeared on an approved Category 5 Integrated Listing are the entries labeled as approved. Integrated Lists are submitted for approval every other year. Segments entered subsequent to the latest approved Category 5 listing are labeled tentative. After appearing on an approved listing, the tentative entries move to approved. The Stream Integrated List is provided as two separate layers determined if the stream is attaining or not attaining its designated uses. DEP Streams Integrated List layer is maintained by the PADEP Office of Water Management, Bureau of Water Supply & Wastewater Management, Water Quality Assessment and Standards Division. The layer is based on the High Resolution National Hydrography Dataset (NHD). Additional update information is provided by Bureau of Watershed Management, Water Use Planning Division.本图层仅展示综合清单（Integrated List）中未达标的河段。溪流综合清单（Streams Integrated List）以整合格式呈现溪流评估成果，用于支撑《清洁水法》（Clean Water Act）第305(b)条报告编制及第303(d)条名录收录。溪流指汇集成网络、用于排泄流域或盆地的流动地表水体。宾夕法尼亚州环境质量部（PA DEP）共划定并保护4类溪流水体指定用途：水生生物生存、鱼类消费、饮用水供应及休闲娱乐。第305(b)条图层对应已针对上述4类用途完成达标评估的河段。若某河段无法满足任意一类指定用途，则被认定为受损河段。 - 水生生物生存用途达标情况：指生物群落任一组成部分的完整性（例如鱼类或鱼类饵料生物）。 - 鱼类消费用途达标情况：指食用水生生物（如鱼类、贝类、青蛙、海龟、小龙虾等）对人体造成的健康风险。 - 休闲娱乐用途达标情况：指在水体中或水体周边开展人类休闲活动所伴随的健康风险（例如通过游泳、滑水等水体接触类休闲活动接触细菌及其他致病微生物的风险）。 - 饮用水供应用途达标情况：指饮用该水体对人体造成的健康风险。 已纳入经批准的第5类综合清单的河段，标注为"已核准"条目。综合清单每两年提交一次审批。在最新获批的第5类清单之后新增的河段，标注为"暂定"条目。暂存条目经核准列入正式清单后，将转为"已核准"状态。 溪流综合清单分为两个独立图层，分别对应河段达标与未达标的情形。本溪流综合清单图层由宾夕法尼亚州环境质量部（PA DEP）水资源管理办公室、供水与废水管理局、水质评估与标准司维护。本图层基于高分辨率国家水文数据集（High Resolution National Hydrography Dataset, NHD）制作。流域管理局、水资源规划司提供了额外的更新信息。
