Guam Waterworks Authority wants $12 million to design an islandwide water treatment master plan for PFAS chemicals and other emerging contaminants.
At a work session with the Consolidated Commission on Utilities Tuesday morning, GWA Assistant General Manager Brett Railey told commissioners the treatment plan is an urgent priority for the agency.
Railey said once the design work is complete, the agency expects to spend "tens of millions millions installing the treatment that’s designed under this project."
"It will definitely be north of $100 million, closer to $200 million," he said.
The project will treat deep wells, reservoirs, booster pump stations and other potentially newly acquired properties on Guam.
The U.S. Environmental Protection Agency has given public water systems a 2029 deadline to implement solutions to reduce PFAS chemicals in the water.
