Friends of the Arcata Marsh (FOAM) is a non-profit
organization which for the last twenty years has advanced
knowledge and educated the public about treatment and
reuse of wastewater. The purpose of the FOAM is to
stimulate understanding of the Arcata Marsh and Wildlife
Sanctuary, its relationship with Arcata's integrated
wastewater treatment system, the surrounding watersheds
and bay, and their link with the earth's water cycle.
