Dungca's Beach, East HagåTñA Bay is a saltwater beach in Guam County, Guam. Across 2,009 bacteria samples collected between 2021 and 2026 at nearby monitoring stations, it earns a Beach Safety Grade of C — Fair.
About 9% of samples at Dungca's Beach, East HagåTñA Bay exceeded the EPA Beach Action Value of 104 CFU/100 mL for Enterococcus — the threshold at which water managers typically post a swimming advisory.

The evidence behind this grade is deep for a beach page: 2,009 results from 5 monitoring stations, spanning 2021 to 2026. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
