DWSAP Program: Guidance
These Source Water Assessment and Protection (DWSAP) Program guidance documents, for DDW 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 DDW 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 DDW.
Surface Water Sources — Guidance and Forms
This section includes guidance for surface water source assessments. It also includes forms that can be used to prepare assessments for surface water sources. When the assessment report for a source is completed, a paper copy of the report should be submitted to the local DDW district offices.

- Assessments for Surface Water Sources — Guidance (PDF) (August 18, 2000)
- Surface Water Assessment Forms (PDF)
- Surface Water Physical Barrier Effectiveness Form (Word)
- Surface Water Source Data Sheet (Excel)
- Surface Water Vulnerability Ranking Spreadsheet (Excel)
- Surface Water Vulnerability Ranking Instructions (Word)
Ground Water Sources Information and Forms
These forms are intended to be used for an assessment for a new groundwater source or groundwater source that have been rehabilitated and in need of a reassessment. 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 DDW district offices

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 DDW's intention is that the water system will collect the basic data, and the DDW district or local primacy agency (LPA) will enter the information into main assessment forms 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 DDW district offices or LPA.
