Nhieu Loc Canal

• Water pollution can also significantly increase the rate of algal blooms. These blooms create massive fish die-offs as the oxygen in water gets depleted and the fish suffocate. Fish can also be killed when excessive algae get caught in their gills.

• Temperature of water increase, causing emigration of fish, thus create an ecological dead zone.

How to Clean Up Our Water?

CITIZEN

1. Decrease impervious surfaces around your home.

2. Use native plants and natural fertilizers

3. Don't over-water lawns and gardens.

4. Recycle and dispose of all trash properly.

5. Correctly dispose of hazardous household products

CITIZEN

6. Use nontoxic household products whenever possible

7. Recycle used motor oil

8. Be "green" when washing your car

9. Help identify, report and stop polluters

10. Be an activist. Educate yourself about water issues in your community.

GOVERNMENT

• Conserve water. Turn off the tap when water isn't necessary and try to take shorter showers if possible.

• This not only helps prevent water shortages, but reduces the amount of contaminated water that needs treatment.

GOVERNMENT

• Don't throw litter into sinks and toilets. Paints, oils and other similar items should be disposed of in the trash.

• Help clean up litter in water-filled areas. This includes beaches, lakes, oceans. Make sure it is safe to collect the litter and put it in a nearby dustbin.

GOVERNMENT

• Contain and compost yard waste. Yard waste that sits around can easily wash into storm drains when it rains.

• Even if the waste doesn't contain chemicals such as herbicides and pesticides, the introduction of large quantities of sticks, leaves, and grass clippings can overwhelm waterways with unhealthy quantities of nutrients.

GOVERNMENT

• Compost yard wastes. Your compost should be contained in a bin or barrel to prevent the materials from being washed away. Some municipalities provide these for free or at low cost.

GOVERNMENT

• Use a mulching mower instead of bagging grass clippings. Mulching mowers add a natural layer of compost to your lawn and you don't have to deal with disposal of grass clippings.

GOVERNMENT

• Dispose of yard and grass clippings properly. If you don't compost or have yard wastes that you can't compost, contact your local waste management or environmental protection agency to determine how to dispose them.
