拟议的加州饮用水源评估和保护计划（DWSAPP）将要求提交该州所有饮用水源的水源评估。评估必须包括水源周围保护区和区域的划定、区域和区域内可能的污染活动（PCA）清单，以及量化水源对污染易感性的脆弱性分析。旧金山公共事业委员会（SFPUC）是由于卫生调查中过去的工作而为DWSAP准备的。保护区由流域边界明确定义，“区域”可由Hetch-Hetchy水库周围300英尺的区域表示，该区域受《联邦耙耙法》卫生规定的保护，以及联邦土地上水体周围100英尺的区域，通常不鼓励或禁止露营。 PCA清单类似于SFPUC优先清单，该清单已作为流域卫生调查的一部分每年进行汇编和更新。地理信息系统（GIS）将用于显示保护区和地带、PCA的位置，以及由此产生的流域易受影响区域。包括表格、数字。

The proposed California Drinking Water Source Assessment and Protection Program (DWSAPP) will require submission of a source water assessment for all drinking water sources in the state. The assessment must include delineation of protection areas and zones around the water source, an inventory of possible contaminating activities (PCAs) within the areas and zones, and a vulnerability analysis that quantifies the susceptibility of the source to contamination. The San Francisco Public Utilities Commission (SFPUC) is prepared for the DWSAPP due to the past work conducted during the sanitary surveys. Protection areas have been clearly defined by watershed boundaries, and "zones" may be represented by the 300 foot zone around the Hetch Hetchy Reservoirthat is protected by sanitary provisions in the federal Raker Act, and the 100 foot zone around water bodies on federal lands where camping is typically discouraged or prohibited. The inventory of PCAs is similar to SFPUC priority lists that are already compiled and updated annually as part of the watershed sanitary survey. Geographic information systems (GIS) will be used to show protection areas and zones, locations of PCAs, and resulting areas of susceptibility in the watershed. Includes tables, figures.
