The drinking water supply management area for a surface water intake (DWSMA-SW) is the surface and subsurface area surrounding a public water supply intake that contains the scientifically calculated surface water protection area and is managed by the entity identified in a surface water protection plan. The boundaries of a DWSMA-SW are delineated by identifiable physical features, landmarks or political and administrative boundaries. Each delineation includes Priority Areas A & B. Priority Area A is delineated starting with an 8-hour time of travel and is intended to manage contaminants that could present an acute (immediate) health concern to water users; Priority Area B is a larger area delineated to manage contaminants that could cause longer-term health effects at lower levels. Priority A and B areas have not been completed for all DWSMA-SW systems. This layer includes A and B areas for Minneapolis, St. Paul and St. Cloud and only.
