Answer 1

Hint: David R. Couch founded Friends of the Arcata Marsh (FOAM) in 1987. It is a non-profit organization. The purpose of the FOAM (Friends of the Arcata Marsh) is to increase awareness and stimulate understanding of the Arcata Marsh Wildlife Sanctuary.

Complete answer:
The citizen group called ‘Friends of Arcata Marsh’(FOAM) belongs to the country U.S.A.(United States of America). It also looks after Arcata's (the city) integrated wastewater treatment system, the surrounding watersheds and bay, and their link with the earth's water cycle. FOAM also provides its information to the public.

Additional Information: -In Arcata, an innovative sewer water treatment is employed to clean the wastewater of the city in two stages:
Conventional stage:
-The primary treatment of wastewater is done through sedimentation. In this, the heavy solid wastes settle down.
-Then the water is filtered and disinfected. The disinfectant commonly used is chlorine.
Innovative: The innovative stage is used to remove very harmful pollutants like dissolved heavy metals, pesticides, etc. It involves the following steps:
-After sedimentation, filtration, and chlorination, the water is passed through a series of six marshes created over 60 hectares of marshland. The marshes are covered with appropriate fungi, algae, and plants are grown.
-The fungi, algae, and plants help in the neutralization and assimilation of pollutants present in the water when they pass from polluted areas. Thus, water is purified naturally.
So, the correct answer is, ‘U.S.A.’

Note: The Board of Directors containing twelve members as well as a president, vice president, and treasurer governs Friends of the Arcata Marsh. The local community members also constitute the Board of Directors. Students from Humboldt State University often serve as a member of the board.
