West HagåTñA Beach is a saltwater beach in Guam County, Guam. Across 1,014 bacteria samples collected between 2021 and 2026 at nearby monitoring stations, it earns a Beach Safety Grade of D — Poor.
About 23% of samples at West HagåTñA Beach exceeded the EPA Beach Action Value of 104 CFU/100 mL for Enterococcus — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was frequently crossed here over the monitored period. Bacteria samples frequently exceed the safe-swimming threshold; swimming advisories are common here.
The evidence behind this grade is deep for a beach page: 1,014 results from 2 monitoring stations, spanning 2021 to 2026. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
In the most recent full reporting year, West HagåTñA Beach was under a swimming advisory for about 37% of its monitored beach days — a useful gauge of how often problems recur here beyond any single sample.
