U.S. EPA National Priorities List (NPL) Sites Point Data with CIESIN Modifications, Version 2

The U.S. Environmental Protection Agency (EPA) National Priorities List (NPL) Sites Point Data with CIESIN Modifications, Version 2 is a modified version of the 2014 EPA NPL list. It includes all the sites that are proposed, currently on, or deleted from the Final NPL as of February 27, 2014. CIESIN has fixed eleven of the original coordinates by correcting latitude or longitude coordinates. It contains the point locations, including the eleven corrections, for 1,747 U.S. hazardous waste sites on the National Priorities List (NPL) of EPA's Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) for the fifty states, Puerto Rico, and 4 other territorial areas plus the now independent Palau, Federated States of Micronesia. The sites in CERCLIS are also known as Superfund Sites. The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation.

美国环境保护署（EPA）国家优先清单（NPL）点位数据，经CIESIN修改版，版本2，是对2014年EPA国家优先清单的修订版。该数据集包含了截至2014年2月27日被提出、正在实施或已从最终国家优先清单中删除的所有点位。CIESIN对原始坐标进行了修正，共校正了11个坐标点。数据集包含包括这11个校正点在内的1,747个美国危险废物点位，这些点位位于EPA综合环境响应、赔偿和责任信息系统（CERCLIS）的国家优先清单上，覆盖了五十个州、波多黎各以及4个其他领土区域，还包括现已成为独立国家的帕劳和密克罗尼西亚联邦。CERCLIS中的点位也被称为超级基金场地。国家优先清单的主要目的是指导EPA确定哪些场地需要进一步的调查。
