WaterWeb - WHPA 300ft Buffer

The Oklahoma Wellhead Protection program is part of a federal program geared to improving drinking water quality by protecting the sources of drinking water. The goal of Oklahoma’s Wellhead Protection program is to minimize the risk of pollution by limiting activities on the land around public water supply wells that might cause pollution. This layer has been generated by drawing 300 ft buffers around the 2014 Public Water Supply Well GIS layer. DEQ rules state that public drinking water wells are not to be located within 300 feet horizontally from any existing or potential source of pollution (OAC 252:626-7-4 3C). This layer is an example of a calculated fixed radius. You should additionally look at the “Wellhead Protection Areas (WHPAs)” GIS layer, that layer was generated by a Numerical Flow/Flow-and-Transport Computer Model. The buffers generated by the computer model show the potential movement of water and/or contaminates around a potential public water source. The “Wellhead Protection Area (WHPAs)” layer should be used if a modeled WHPA has been generated for the public water supply well of interest.俄克拉荷马州井口保护计划（Oklahoma Wellhead Protection Program）隶属于一项旨在通过保护饮用水水源以提升饮用水水质的联邦计划。该计划的目标是通过限制公共供水井周边土地上可能引发污染的各类活动，最大程度降低污染风险。本图层通过对2014年公共供水井地理信息系统（GIS）图层创建300英尺缓冲区生成。俄克拉荷马州环境质量部（DEQ）的规章规定，公共饮用水井不得与任何现有或潜在污染源保持水平距离小于300英尺（OAC 252:626-7-4 3C）。本图层为计算得到的固定半径缓冲区的示例。您还需参考"Wellhead Protection Areas (WHPAs)"地理信息系统图层，该图层由数值流/流场与输运计算机模型生成。该计算机模型生成的缓冲区可展示潜在公共水源周边水体及/或污染物的潜在运移路径。若针对目标公共供水井已生成建模后的井口保护区，则应采用"Wellhead Protection Area (WHPAs)"图层。
