Water Pollution Ocean Dumping Ship Pollution -Ships release tons of harmful waste into the ocean.
-Include grey water, sewage, bilge and ballast water. Fish Kill Acid Rain -Contains sulfuric acid or nitric acid.
-Lowers pH in lakes and rivers.
- Marine life die due to acidity.
-Contaminates our drinking water.
-Corrodes water pipes. What is water pollution? Urban Runoff Mercury in Fish Algal Bloom Waste Water Marine Pollution Thermal Pollution Water Crisis Oil Spills 13 largest Oil Spills in History 1. Arabian Gulf/Kuwait

When: March 18, 1967
Where: Scilly Isles, UK
Amount spilled: 25-36 million gallons Water pollution is any chemical, physical or, biological change in the quality of water that has a harmful effect on any living thing that drinks, uses, or lives in it. -Disposal of waste at sea.
-Human created either deliberately or accidentally.
-Accumulates in coastlines
-Plastics in water harm animals. Physical effects of water pollution to the human body Life in the Ocean Affected by Oil Spills Seabirds
Habitat -Mass kill-off of localized fish.
-First sign of environmental stress.
-Oxygen depletion is a main cause. How do you clean up an oil spill? Booms -- Floating barriers placed around the oil or around whatever is leaking the oil. Booms contain the oil so skimmers can collect it.
Skimmers -- Boats, vacuum machines, and oil-absorbent plastic ropes that skim spilled oil from the water's surface after booms have corralled it. The skimmer collects oil into a container so it can be removed.
Chemical dispersant -- Materials that break down the oil into its chemical constituents. This helps disperse the oil and make it less harmful to wildlife and shorelines.
In-situ burning -- Igniting freshly spilled oil while it's still floating on the water. 4. Atlantic Empress Oil Spill
When: July 19, 1979
Where: Off the coast of Trinidad and Tobago
Amount spilled: 90 million gallons How oil Spills Occur when a country is at war
tanker equipment breaks down
terrorists dump oil to get another country's attention
natural disasters (hurricanes) Thermal pollution is the act of altering the temperature of a natural water body, which may be a river, lake or ocean environment. Marine Pollution is Land-based sources (such as agricultural run-off, discharge of nutrients and pesticides and untreated sewage including plastics) account for approximately 80% of marine pollution, globally. Marine habitats worldwide are contaminated with man-made debris. Oil spills remain a concern, though actual spills have decreased steadily for several decades. Children: Every 20 seconds, a child dies from a water-related illness Women: Women spend 200 million hours a day collecting water Water: More than 3x more people lack water than live in the United States Disease: The majority of illness is caused by fecal matter Sanitation: More people have a mobile than a toilet Economic: Lack of community involvement causes 50% of other projects to fail Water scarcity is an abstract concept to many and a stark reality for others. It is the result of myriad environmental, political, economic, and social forces. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. Rain water that runs through impervious surfaces that collects pollutants , which is discharged to rivers lakes and bays. -Due to water pollution fish carry mercury.
-Especially dangerous to pregnant women How to help -Tumors and ulcers.
-Skin disorders due to contact with pollutants.
-Constipation, diarrhea and infections to intestine.
-Dangerous effects on growing fetus in pregnant women.
-Still births, abortions and birth of deformed children.
-'Blue baby' disease - which results in asphyxia
-Reduced activity of immune system.
-Loss of memory and reduced mental sharpness.
-Water borne diseases i.e jaundice, hepatitis, gastroenteritis
-Reduced bone development and muscular development.
-Reduced male fertility.
-Cancer high concentrations of nutrients from agricultural and urban runoff
form over spacialy large areas such as estuaries and coastal waters
limit plant growth
can also be referred to as Red Tides In your yard Decrease impervious surfaces in your home. Use native plants and natural fertilizers. Do not over water plants. At home Recycle and dispose of trash properly Correctly dispose of hazardous household products Use nontoxic household products whenever possible. Your car In your community Recycle used motor oil. Be "green" when washing your car Help identify, report and stop polluters Be an activist. Forced Migration
Bad oxygen and temperature environments will prompt organisms to move away from the area and populate new areas, radically changing the ecosystems in both areas. Some power plants have introduced heat-shock proteins to the discharge to protect some organisms from the changes in temperature. Shorter Plant Life
An increase in water temperature increases the growth rates of aquatic plants, which results in a shorter life for the plants and overpopulation of the species. A rush of warm water can cause an algae bloom that will reduce the oxygen in the water, cause increased plant respiration, and cloud the water. water that has been used in a way that negatively affects its quality; usually containing pollutants
forms of waste water: domestic/industrial/agricultural
black water and grey water
failing Septic systems can also have negative affects
waste water treatment plants play a major role in the recycling of wasted water
