JIC Recovery Release No. 27 - DPHSS Cautions Against Standing Water; GPA Update; GSWA Update

DPHSS Cautions Against Standing Water:

The Department of Public Health and Social Services (DPHSS) encourages the public to inspect the premises around their homes and businesses for standing water where mosquitoes may breed. Heavy rainfall may create conditions suitable for increased mosquito breeding, particularly the Aedes mosquito which breeds in containers. Debris strewn by the storm may be collecting water and breeding this mosquito. Aedes mosquitoes are known transmitters of Dengue Fever and Chikungunya virus, and while these two mosquito-borne diseases are not currently found on Guam, they can be imported and spread by Aedes. Neighboring islands in the Pacific, and Asia, frequently endure outbreaks of mosquito-borne diseases.


Take these steps to limit mosquito breeding sites at your home or business:

  • Clean all debris, especially those that can hold water.

  • Dispose of loose tires.

  • Clean pet water dishes regularly.

  • Clean, empty, and properly screen or cover containers used to store water.

  • Clear roof gutters of debris.

  • Properly dispose of all bottles, cans, buckets and other containers that can collect and hold water.

  • Plug tree holes.

  • Repair leaky outdoor faucets so as not to create standing water.

  • Change the water frequently in flower vases and other containers that routinely contain water.


The public is also advised to wear light-colored, loose-fitting clothing during outdoor activities as mosquitoes are attracted to dark colors.  When practical, wear long-sleeves and pants when going outdoors. Decrease your risk of mosquito bites by properly applying mosquito repellents containing 20% - 30% DEET as the active ingredient on exposed skin and clothing.

GPA Update:

The Guam Power Authority (GPA) advises the community of the proper use of generators during a power outage. If installed and operated correctly, use of standby or portable electric generators poses little danger, but improper installation or use could be dangerous and even deadly. Follow the directions from the operator’s manual supplied with the generator. Incorrect generator use can lead to carbon monoxide (CO) poisoning, electric shock or electrocution and fire. 


GPA provides the following tips for the safe operation of and use of generators: 

Connecting the Generator

  • Never try to power house/building wiring by plugging the generator into a wall outlet, a practice known as "back feeding". It can lead to electrocution of utility workers or neighbors served by the same utility transformer. The only safe way to connect a generator to a house/building wiring is to have a qualified electrician install a power transfer switch.  

  • Use proper extension cords. Use only safety-tested, shop-type electrical cords designed and rated for heavier, outdoor use to connect appliances.  

  • Protect your appliances. Turn off or unplug all appliances and lights before you begin operating the portable generator. Once the generator is running, turn your appliances and lights on one at a time to avoid overloading the unit. 

Placement of Generator: 

  • Never use a portable generator indoors – If you or someone starts to feel sick, dizzy or weak while using a generator, move to fresh air right away, do not delay.  

  • Place the generator in a dry, outside location.  

  • Place the generator away from windows, doors, and vents that could allow CO to come indoors.  

  • To avoid electrocution, keep the generator dry. Do not use it in rain or wet conditions. Always operate generators on a dry surface under an open canopy-like structure. Make sure your hands are dry before touching the generator. 

Use and Storage of Generator Fuel:

  • Turn the generator off and let it cool before refueling. Gasoline spilled on hot engine parts could ignite.

  • Store fuel in an approved safety can outside of living areas, preferably in a locked area or other protected area.  

  • If you spill fuel or do not seal the container properly, invisible vapors can travel along the ground and be ignited by arcs from electric switches in the appliance.  

  • Use the type of fuel recommended in the generator instructions or on its label. 

Shutting down the Generator:

  • Before shutting down a generator, turn off and unplug all appliances and equipment being powered by the generator. 


Damaged Weatherheads and other Electrical Components 

While restoration is ongoing, customers are advised to conduct their own home and property assessment of weatherhead and electrical components, taking necessary steps to repair damages caused by Typhoon Mawar. 


Frequently Asked Question:  My weatherhead and/or electrical components (meter box, service entrance conduit & cable, riser) are damaged. What should I do? These components are the customer’s responsibility. 

  1. Account holder or authorized person visits any of GPA’s Customer Service lobbies and requests for a work clearance. A GPA representative will issue a work clearance and a GPA Electrical Inspection Report form. 

  2. GPA crew will schedule removal of the service line and meter. Once removed, customers can hire and schedule contractor/master electrician to make repairs. A list of licensed master electricians is available on the Guam Contractors License Board website at http://clb.guam.gov/index.php/contractors-listing/.

  3. Upon completion of repairs, the master electrician must print name, sign and include ME license number on GPA’s Electrical Inspection Report form. Please contact GPA Customer Service at (671) 647-5787/88/89 or email customersfirst@gpagwa.com, informing representatives of the completed work.

  4. Customers will be contacted once meter installation and service line reconnection is scheduled. Customers must present an Electrical Inspection Report to GPA crew upon arrival.

GSWA Update:

Since resuming collections on Monday, May 29, 2023, the Guam Solid Waste Authority (GSWA) has collected over 771 tons of trash. This significant increase in waste requires additional time and resources to ensure proper disposal.


Residents who are normally serviced on Thursday will be serviced on Friday, June 2, 2023. GSWA requests everyone’s cooperation in leaving their trash curbside if it has not yet been collected, as GSWA continues to address all pending collections as quickly and efficiently as possible, to all residents in single-family homes and apartments with four (4) units or less, including those who are not registered customers of GSWA.
