Source Water Assessment and Protection Program (SWAPP) Ground Water Areas (Non Federal)

Assessment areas were created for each Public Water Supply (PWS) well to identify potential contamination sources. PWS wells are divided into three categories: 1) noncommunity, 2) community serving populations less than 1,000 persons and 3) community serving populations greater than or equal to 1,000 persons. Assessment areas for noncommunity wells are a 500 ft radius buffer of the well. Assessment areas for community wells serving populations = 1,000 persons are a 1,000 ft radius buffer of the well plus a five year ground water travel time.为每一口公共供水（Public Water Supply, PWS）水井划定评估区域，用于识别潜在污染源。公共供水水井可分为三类：1）非社区型水井；2）服务人口不足1000人的社区型水井；3）服务人口大于或等于1000人的社区型水井。非社区型水井的评估区域为以该水井为中心、半径500英尺的缓冲区域。服务人口等于1000人的社区型水井的评估区域，为以该水井为中心、半径1000英尺的缓冲区域叠加五年地下水运移时间所覆盖的范围。
