NEWS: Guam EPA Recognizes Radon Action Month, completes new radon lab installation

January 23, 2018 (Tiyan, Guam) — The Guam Environmental Protection Agency (Guam EPA) has completed the installation of its new radon testing laboratory. The lab features the latest in radon detection technology married with sustainable software and hardware enhancements that will bring Guam’s radon testing capability to the forefront and on par with our national counterparts. Proficiency performance testing and calibration for the lab have been completed this month with the assistance of Dr. James F. Burkhart, physics professor at the University of Colorado, Colorado Springs, Colorado and director of the Western Regional Radon Training Center established by the U.S. Environmental Protection Agency. Guam EPA looks to obtain certification for the agency radon lab in March.

Radon is a radioactive, tasteless, colorless and odorless gas that forms from the natural decay of certain elements in rocks and soil. As a result of this decay, radon gas is emitted into the atmosphere and can seep into home and office buildings. Radon is classified as a carcinogen and long-term radon exposure has been linked to lung cancer. Radon levels are measured in “picoCuries per liter (pCie/L)” and the action level for mitigation in your home or office is 4pCie/L of air.

“Radon Action Month” is traditionally recognized in January. This year, Guam EPA acknowledged Radon Action Month with a proclamation signing ceremony with Lieutenant Governor Ray Tenorio at the Governor’s Complex in Adelup on January 23, 2018. Radon Action Month is a national campaign that aims to raise awareness about the dangers of radon in the home and office and how mitigation techniques can be implemented to reduce the amount of radon exposure. According to the USEPA and the Surgeon General’s Office, radon is the second leading cause of lung cancer in the United States, just behind tobacco smoking. Statistics show that radon related lung cancer claims some 24,000 lives annually – claiming more lives than drunk driving and drowning.

Guam EPA Administrator Walter S. Leon Guerrero stated, “Previous studies conducted by our agency have shown that radon is problem on Guam and that testing your home or office is the only way to determine radon levels.” Leon Guerrero also adds, “We are pleased to be working with USEPA’s Indoor Radon Program and we are grateful for the funding that Guam EPA has received through our consolidated grant to outfit our lab. We look to continue to enhance our service to the public through this lab.” Additional support for the Guam EPA’s radon lab has also come by way of a memorandum of agreement between the agency and the University of Guam. Testing for radon in your home or office is easy and inexpensive and should be done at least once every five years. The type of mitigation that is required to reduce radon exposure in the home or office depends on the current radon level in the structure.

Guam EPA is conducting beta testing and staff development in order to ensure efficiency for residents who wish to have the agency test their homes for radon. Guam EPA will inform the residential community when the service will be available once the outreach phase is finalized.

NEWS: Guam EPA reports 32.34% recycling rate – up 3.34 points

15 November 2017

November 15, 2017 (Tiyan, Guam) — The Guam Environmental Protection Agency (Guam EPA) reports a 32.34% recycling rate for all eligible discarded materials in calendar year 2016. This represents an increase of 3.34 percentage points to last year’s reported recycling rate of 29%. Data collection for the recycling rate has been analyzed and calculated based on reported figures from our island’s permitted waste disposal and recycling facilities since 2011. Guam EPA first reported a recycling rate of 17.85% in 2012, representing over 29,000 tons. Discarded materials that are ineligible for data collection towards the recycling rate include: construction and demolition debris, bio-solids and vehicles.

Guam EPA has historically released the island’s recycling rate on “America Recycles Day.” This year, Guam EPA celebrated America Recycles Days with a proclamation signing ceremony with Lieutenant Governor Ray Tenorio at the Governor’s Complex in Adelup. America Recycles Day is a national campaign that aims to raise awareness about the benefits of recycling and buying products made with recycled materials. According to the United States Environmental Protection Agency, the national recycling rate in the United States is 34%.

Guam EPA Administrator Walter S. Leon Guerrero stated, “In recognition of America Recycles Day, our agency is pleased to report that over 47,000 tons of waste has either been recycled or mulched and composted and will never find a way into our landfill.” Discarded materials that are eligible for data collection include: cardboard, mixed paper, e-waste, ferrous and nonferrous metals, tires, automotive batteries, plastics, mulched and composted material. Leon Guerrero also adds, “With this rising trend in materials that are recycled or reused, Guam is on a great path towards our goal of the zero waste.”

Guam EPA has observed that some factors can affect our island’s recycling rate. Global market value on certain recyclables can adversely impact the export on certain recyclable commodities. Positive contributions towards the recycling rate include promoting awareness in promoting reduction in the waste stream in the community through public and private sector involvement, active participation with our youth groups in the collection of discarded materials around the island and curbside recycling programs.

This year’s statistics revealed significant increases in the following categories:
