The US Environmental Protection Agency has wrapped up a major cleanup effort at the Dededo Transfer Station, removing about 31,000 cubic yards of contaminated soil containing heavy metals and PCBs. 

EPA officials say the $14.5 million project — done in partnership with the Guam Environmental Protection Agency — was years in the making.

The 10-acre site, located northwest of Marine Corps Drive and Bartolu Street, had long served as a waste transfer and debris staging area but deteriorated over time, leading to illegal dumping and toxic exposure risks.

EPA Pacific Southwest director Mike Montgomery says the cleanup ensures that “toxins like lead and pcbs do not threaten human health or the environment.”

The project included the removal and safe disposal of contaminated soil, along with the installation of new fencing to prevent future dumping.

EPA began assessing the site in 2019 after GEPA requested federal help, and the cleanup was completed earlier this year.
