Screening uses physical barriers to remove large flotables.

This is the correct answer. Flotation uses air bubbles to make flotables rise to the surface.

Skimming uses a mechanical device to collect flotables from the water surface.

This method is used for organic flotables.

Urban runoff can carry a variety of flotables.

Industrial discharge can contain flotables.

Agricultural activities can contribute to floatable materials.

This is the correct answer. Deep ocean currents are not a major source of flotables.

Here is a sample floatable management plan, focusing on the example of the small lake:

Sources of flotables:

• Littering: People may be discarding plastic bottles and other trash near the lake.
• Windblown debris: Leaves and other plant matter can be blown into the lake from surrounding areas.
• Animal activity: Wild animals and domestic pets may contribute animal waste to the lake.
• Runoff: Stormwater runoff from nearby roads and parking lots can carry plastic debris and other flotables.

Removal methods:

• Skimming: Use a mechanical skimmer to collect plastic bottles, leaves, and other larger flotables from the water surface.
• Nets and rakes: Manually remove floating debris using nets or rakes.
• Trash bins: Place trash bins at strategic locations around the lake to encourage responsible waste disposal.

Prevention strategies:

• Public education: Conduct awareness campaigns to educate the community about the importance of reducing floatable debris and proper waste disposal.
• Stormwater management: Implement stormwater management measures to prevent runoff from carrying pollutants and flotables into the lake.
• Litter patrols: Organize regular litter patrols to collect trash from the lake and surrounding areas.
• Wildlife management: Implement strategies to manage wildlife populations and minimize animal waste entering the lake.

Public awareness:

• Community events: Organize lake clean-up events involving local residents and volunteers.
• Signage: Place signs around the lake reminding people to dispose of trash properly and avoid littering.
• Social media: Use social media platforms to share information about floatable management and promote responsible lake use.

This plan outlines a comprehensive approach to addressing the floatable issue in the lake. It involves identifying sources, implementing appropriate removal methods, taking preventative steps, and fostering public engagement for a cleaner and healthier lake environment.
