Transcript of Water Pollution

What is Water Pollution ?
Water pollution : is the contamination of water bodies with harmful compounds
Human Waste

-When toxic substances enter a body of water, they will be dissolved, become suspended in water or get deposited on the bed of the water body.

-The resulting water pollution causes the quality of the water to deteriorate and affects aquatic ecosystems.

-Such water, which ultimately ends up in our households, is often highly contaminated and can carry disease-causing microbes.

3 solutions to stop water pollution :
Effect on Animals
Toxic Materials causes animals to have
Behavior abnormalities
SUch As :
Reproductive changes

Water Pollution

Solution #1 : Beach Clean-Ups

Have regular beach cleanings to reduce trash on beach surface
Have lots of trash cans around beaches for easy access to dispose of waste
Have signs encouraging to throwaway your waste
This picture demonstrates the teaching of beach
clean-ups to younger audiences in Orange count7y.

This picture explains the trash pollution on the surface of OC Beaches.

This is the before and after effect of a beach clean-up.

Solution #2: Recycle
Recycling reduces waste going into oceans
Encourage recycling programs and have more recycling bins around beaches and in homes
Teach younger children to recycling in order to reduce the deaths of sea animal
Picture shows recycle bins in our local beaches that we could us to improve the habit of recycling.

Picture shows a possible ways to recycle plastic bottle in beaches instead of throwing them away.

Picture demonstrates the negativity that sea animals have against waste going into beaches and prefer to have them recycled.

Solution #3: Chemical disposals
Picture shows the possible before and after effect of chemicals in local water disposed in the ocean .

This pictures shows a recent oil spill at an Orange County Beach and the effect it caused.

Chemicals are released in oceans that can cause major side effects in humans and sea animals
Have a facility that allow chemical workshop to dispose of waste
Ban the allowance of chemical waste into sewers
Contain oil spills around local beaches

Beach Clean-ups
Chemical Disposal
CAUSE #1: Agriculture Waste
pesticides can cause water pollution and poison aquatic life. Subsequently, birds, humans and other animals may be poisoned if they eat infected fish.
Animal waste can also cause water pollution, because rain washes it to the lakes and oceans
Fertilizer also affects water, because of the multiple chemicals in it

oils- do not dissolve in water instead forms a layer on water surface and stops marine plants from receiving enough light
Metals and solvents from industrial work can pollute rivers and lakes
Petroleum is another form of chemical pollutant that usually contaminates water through oil spills when a ship ruptures. Oil spills usually have only a loCalised affect on wildlife but can spread for miles. The oil can cause the death of many fish and stick to the feathers of seabirds causing them to lose the ability to fly.

Each time the air is polluted with sulfur dioxide and nitrogen oxide, they mix with water particles in the air and form a toxic substance, which falls as acid rain and is washed into water bodies
The result is that, water bodies get contaminated affecting animals and water organism

This picture shows all the different ways agriculture has an effect on the worlds WATER pollution
human waste

As you can see by the graph sewage has the highest percentage in pollutants entering the oceans. Followed by farm (Agriculture)

SEWAGE refers to liquid wastes containing a mixture of human feces and waste water from non-industrial human activities such as bathing, washing, and cleaning
IN MANY COUNTRIES sewage is dumped into local waterways (UNTREATED SEWAGE)
Untreated sewage poses a major risk to human health, IT also destroys aquatic ecosystems
SEWAGE PIPES rust and begin to leak, contamiNATING the soils, and the liquids WHICH THEN end up in many nearby water bodies
Effect on Humans
Effects of water pollution
Effects on animals
effects on humans
effects on Human Waste


Cause #4: Human Waste

-Without proper hand-washing and restroom facilities, people face sanitation issues that may lead to illness which is carried through in our water
-Residential waste (household), which became one of the causes water pollution due by human activity itself.
-Water pollution is human activity which then creates waste (garbage) residential or household waste.
