Utah DDW Groundwater Source Protection Zones

These data represent Drinking Water Source Protection (DWSP) zones for groundwater sources operated by Public Water Systems (PWS) in Utah. These zones have been delineated by PWS to comply with the requirements of Utah Administrative Code (UAC) Rule R309-600. The protection zones are submitted to the Utah Division of Drinking Water as part of Drinking Water Source Protection plans. Base maps are required to be at a scale of 1:24,000. Many zones have been manually digitized from paper maps at a scale of 1:24,000. Zone 1 = 100-feet radius around the source Zone 2 = 250-day groundwater time-of-travel Zone 3 = 3-year groundwater time-of-travel Zone 4 = 15-year groundwater time-of-travel

本数据集涵盖犹他州由公共供水系统（Public Water Systems, PWS）运营的地下水水源饮用水水源保护（Drinking Water Source Protection, DWSP）分区。上述保护分区由各公共供水系统划定，以满足犹他州行政法规（Utah Administrative Code, UAC）R309-600号规章的相关要求。该类保护分区已作为饮用水水源保护计划的组成部分，提交至犹他州饮用水管理部门。底图的法定比例尺为1:24000，多数保护分区系按照该比例尺从纸质地图手动数字化得到。其中，1区为水源周边半径100英尺的范围，2区为地下水运移时长250天的区域，3区为地下水运移时长3年的区域，4区为地下水运移时长15年的区域。
