Guam EPA Weekly Beach Report: 13 Advisories, 1 Closed


Guam – The Guam EPA weekly Beach Report lists Advisories on 13 beaches and the same beach remains closed.


The Recreational Waters Pollution Report is compiled by Guam EPA’s Environmental Monitoring and Analytical Services Division.

Advisories are based on an instantaneous standard of not greater than 104 enterococci/100 ml and a geometric mean standard of not greater than 35 enterococci/100 ml.

Swimming, fishing or playing in unsafe waters may result in minor illnesses such as sore throats or diarrhea. It might also result in more serious illnesses such as meningitis, encephalitis, or severe gastroenteritis. Children, the elderly and people with weakened immune systems have a greater chance of getting sick when they come in contact with contaminated water.

No weekly testing is done on West Hagåtña Bay, but it remains closed, as it has been for years, because GWA, on occasion, uses an old, fractured, outfall pipe to dispose of sewage  from the Hagåtña Sewage Treatment Plant. When that happens, some of the sewage can leak inside the reef and pollute the waters and beaches in the area including the Hagåtña Boat Basin & Channel and the West Hagåtña Beach Park.

Since 1974, Guam EPA has performed this community service weekly. The Environmental Monitoring and Analytical Services Division takes water samples of 42 recreational beaches every Thursday [ adjustments are made during official holidays] and analyzes the samples for concentrations of the enterococcus bacteria indicator.

Questions about the Recreational Waters Pollution Report should be directed to the Guam EPA Monitoring Section at 475-1656/8.
