Water system maps

Each state's systems drawn on their EPA service area boundaries and shaded by the most recent loss figure each one filed.

By state

The shading bands are fifths of that state's own distribution. They are not a national scale: the regulators in this corpus measure different quantities, and a figure from one state does not compare to a figure from another.

← The water loss index — every system in the corpus, by state.

"Water loss" is at least three different quantities depending on the jurisdiction, and nothing here supports a comparison between states.
