Options

A. Reducing eutrophication
B. Sewage and water treatment
C. Radio- active waste treatment
D. Minimizing global warming

Answer

**Step-by-Step Solution:**

1. **Identify the Group**: FOAM stands for Friends of the Arcata Marsh, which is a community organization.

2. **Understand Their Responsibility**: FOAM is responsible for an integrated process that involves managing water quality issues, particularly focusing on reducing eutrophication and treating sewage and wastewater.

3. **Define Integrated Wastewater Treatment**: This process includes various steps to clean water effectively. The first step is conventional sedimentation, where solids settle out of the water.

4. **Additional Treatment Steps**: After sedimentation, the water undergoes filtering and chlorine treatment to eliminate pathogens. However, some dangerous pollutants, like heavy metals, may still remain.

5. **Innovative Solution**: To address the remaining pollutants, biologists created a series of six interconnected marshes over 60 hectares. These marshes are planted with specific plants, algae, and bacteria that can absorb and assimilate the pollutants.

6. **Natural Purification Process**: As water flows through these marshes, it undergoes natural purification, making it cleaner and safer for the environment.

7. **Conclusion**: FOAM plays a crucial role in maintaining and safeguarding this integrated wastewater treatment project, which is essential for the health of the Arcata Marsh ecosystem.

**Final Answer**: FOAM (Friends of the Arcata Marsh) is responsible for the integrated process of sewage and water treatment.
