American Samoa Water Systems by Source Type

Source-type hubs separate systems that rely primarily on underground aquifers from systems that rely on rivers, lakes, and reservoirs. This supports cleaner comparison neighborhoods for source-specific risk context.

Ground Water Systems

Systems that draw primarily from underground aquifers. Ground water systems face distinct risk profiles including well field maintenance, aquifer depletion, and contamination vulnerability from surface activities.

Surface Water Systems

Systems that draw primarily from rivers, lakes, or reservoirs. Surface water systems face treatment complexity, seasonal variability, watershed protection demands, and exposure to drought and climate patterns.
