Delineation of source water protection areas is the process of defining the area of land in which activities are likely to impact the quality of the drinking water source.Sources of water are divided into three zones. The delineation method is dependent on several factors, depending upon the source type, as described below.
Groundwater:
- Narrative methodology - provides rationale and procedure for delineating wellhead protection areas.
- Tabular summary - provides technical basis for delineation of wellhead protection areas.
Surface water:
- Reservoirs - provides rationale and procedures for delineation of surface water protection areas for reservoirs.
- Rivers and streams - provides rationale and procedures for delineation of surface water protection areas for rivers and streams.
- Ohio River - provides rationale and procedures for delineation of surface water protection areas for the Ohio River.
