DWSAP Program: Guidance
These Source Water Assessment and Protection (DWSAP) Program guidance documents, for CDPH staff and for staff of Local Primacy Agency (LPA) counties, are intended to help in the preparation and review of source water assessments. Water systems or others using these documents are urged to contact their local DHS district office or LPA county if they have specific questions.
Most of the background information on assessment procedures can be found in the DWSAP Program Document (PDF, 1.6MB), prepared by the Department of Health Services, the precursor to CDPH.
Surface Water Sources — Guidance and Forms
Surface water source assessments should be submitted using the TurboSWAP program. This section includes guidance for surface water source assessments. It also includes forms that can be used to prepare assessments for surface water sources, but the use of TurboSWAP is highly encouraged. When the assessment report for a source is completed, a paper copy of the report should be submitted to the local CDPH district office (PDF).

Ground Water Sources Information and Forms
TurboSWAP is available for existing groundwater sources used for drinking water.
These forms are intended to be used for an assessment for a new source, and the forms are structured so that CDPH staff can enter the assessment into TurboSWAP easily. We recommend that those who propose to use these forms contact their district engineer first. When the assessment report for a source is completed, a paper copy of the report should be submitted to the local CDPH district office (PDF).

Small Water Systems — Forms for Ground Water Sources and Surface Water Sources (May 2002)
These Source Water Assessment forms are for small water systems doing assessments for new sources. They are not as complete as those presented elsewhere, because DHS' intention is that the water system will collect the basic data, and the CDPH district or local primacy agency (LPA) will enter the information into TurboSWAP when they issue the permit. This process is more effective and expeditious than teaching small water system personnel all the procedures for source water assessments. When the assessment forms for a source are completed, a paper copy of the forms should be submitted to the local CDPH district office (PDF) or LPA.
