资源简介：

Connecticut 303(d) Impaired Waters 2014 is a subset of Connecticut 305(b) Assessed Waters 2014. If any one of the assigned designated uses is categorized as NOT Supporting, the assessed waterbody is included in this subset and is considered impaired. Additional information about Integrated Water Quality reporting is available on the CT DEEP website, <a href='https://portal.ct.gov/DEEP/Water/Water-Quality/Water-Quality-305b-Report-to-Congress' style='color:rgb(0, 121, 193); text-decoration-line:none; font-family:inherit;' rel='nofollow ugc'>Integrated Water Quality Report</a> page. Connecticut 305(b) Assessed Waters files includes rivers, lakes and estuaries that have been assessed in compliance with Sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.This assessment is based on information collected and compiled prior to 2014. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this information geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish harvesting, and drinking water supply.

康涅狄格州2014年《清洁水法》第303(d)条受损水体，是康涅狄格州2014年《清洁水法》第305(b)条评估水体的子集。若任意一项指定用途被归类为“不支持达标”，则该评估水体将被纳入此子集，并被认定为受损水体。有关综合水质报告的更多信息，可访问康涅狄格州能源与环境保护部（CT DEEP）官网的<a href='https://portal.ct.gov/DEEP/Water/Water-Quality/Water-Quality-305b-Report-to-Congress' style='color:rgb(0, 121, 193); text-decoration-line:none; font-family:inherit;' rel='nofollow ugc'>综合水质报告</a>页面。康涅狄格州2014年《清洁水法》第305(b)条评估水体数据集涵盖了依据联邦《清洁水法》第305(b)与303(d)条完成合规评估的河流、湖泊及河口。《清洁水法》第305(b)条要求各州对辖区内水体开展监测、评估，并汇报其水质是否达到州水质标准所设定的各项指定用途要求。第303(d)条则要求各州从上述评估清单中筛选出未达水质标准的水体子集，并为每一处受损水体分配日最大负荷总量（Total Maximum Daily Load，简称TMDL）优先级排名。本次评估基于2014年之前收集并汇编的信息，仅反映特定时间点的水体状况，不代表当前实际水质情况。根据水体类型（河流、湖泊或河口），该数据集将以地理维度展示各项指定用途的达标与未达标状态——包括水生生物、海洋水生生物、娱乐用水、鱼类消费、贝类养殖以及饮用水供应——具体分为完全达标、未达标、未评估三类。
