Water Day1992March 22

by Monica EhlermannWater 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.

TOP WAYS OF POLLUTION.

Ocean Dumping•Disposal of waste at sea.•Human created either

deliberately or accidentally.•Accumulates in coastlines• Plastics in water harm animals.

Ship pollution• Ships release tons of harmful

waste into the ocean.• Include grey water, sewage, bilge

and ballast water.

Fish kill•Mass kill-off of localized fish.

• First sign of environmental stress.•Oxygen depletion is a main

cause.

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.

Urban runoffRain water that runs through impervious surfaces that collects pollutants , which is discharged to rivers lakes and bays.

Mercury in fish•Due to water pollution fish carry

mercury.• Especially dangerous to pregnant

women

Algal BloomHigh concentrations of nutrients from agricultural and urban runoffform over specially large areas such as estuaries and coastal waterslimit plant growth can also be referred to as Red Tides

Wastewater

Water that has been used in a way that negatively affects its quality; usually containing pollutants forms of waste water: domestic/industrial/agriculturalBlack water and grey waterFailing Septic systems can also have negative affectswaste water treatment plants play a major role in the recycling of wasted water.

Oil Spills bY aDRIANA COTTO

How do you clean up an oil spillBooms

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.

How oil spills occur• When a country is at war• Tanker equipment breaks down• Terrorists dump oil to get another country's

attention • Illegal dumpers • Natural disasters (hurricanes)

Marine Pollution pBy. Rodrigo Perez

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.

THERMAL POLLUTION.

Thermal pollution is the act of altering the temperature of a natural water body, which may be a river, lake or ocean environment.

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 CRISIS.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.

Children Every 20 seconds, a child dies from a water-related illness

WomenWomen spend 200 million hours a day collecting water

DiseaseFecal matter causes the majority of illness

WaterMore than 3x more people lack water than live in the

United States

SanitationMore people have a mobile than a toilet

EconomicLack of community involvement causes 50% of other

projects to failWhile nearly 70 percent of the world is covered by water,

only 2.5 percent of it is fresh.
