How we matched ZIP 93062: we translate the ZIP to a city and county via the Geonames postal database, then match against service-area cities and counties EPA has on file for each public water system. EPA does not publish authoritative service-area boundary maps for most systems, so there is still some guesswork; large regional authorities (e.g., county-wide water and sewer authorities) are usually filed at the county level even when they serve specific cities. Your water bill names the authoritative utility. Methodology.
