Well Head Protection Areas for Public Non-Community Water Supply Wells in New Jersey

A Well Head Protection Area for a Public Non-Community Water Supply Well (PNCWS) in New Jersey is a map area calculated around a Public Non-Community Water Supply well that delineates the horizontal extent of ground water captured by a well pumping at a specific rate over a two-, five-, and twelve-year period. GIS coverages are produced for each PNCWS well and for the set of all PNCWS wells in each county and for the state. The individual, county and state coverages are prepared for distribution as uncompressed ARC/INFO export files. The export files are combined with parameter-reference files for each county in compressed 'zip' files for delivery over the Internet. Public Non-Community Water Supply Well Head Protection Area downloads therefore include line and polygon GIS coverages with associated database files, and parameter-reference files for data documentation. The documentation files are ASCII text files having the 'txt' extension. WHPA delineation methods are described in "Guidelines for Delineation of Well Head Protection Areas in New Jersey" available as a download at www.nj.gov/dep/njgs/whpaguide.pdf.新泽西州公共非社区供水井（Public Non-Community Water Supply Well, PNCWS）的井头保护区（Well Head Protection Area, WHPA）是围绕该类供水井划定的地图区域，用于勾勒特定抽水量的水井在2年、5年及12年周期内所捕获的地下水的水平波及范围。本数据集为每一口公共非社区供水井、各县域内的全部公共非社区供水井集合及全州范围生成GIS覆盖数据。针对单井、县域及全州的GIS覆盖数据均以未压缩的ARC/INFO导出文件形式进行分发。上述导出文件将与各郡的参数参考文件一同打包为压缩ZIP文件，以供互联网传输下载。公共非社区供水井井头保护区的下载包包含带关联数据库文件的线要素与面要素GIS覆盖数据，以及用于数据文档说明的参数参考文件。此类文档文件为扩展名为.txt的ASCII文本文件。井头保护区的划定方法详见《新泽西州井头保护区划定指南》（"Guidelines for Delineation of Well Head Protection Areas in New Jersey"），可通过网址www.nj.gov/dep/njgs/whpaguide.pdf下载获取。
