INTRODUCTION

Global warming is the rise in the average temperature of

Earth's atmosphere and oceans since the late 19th

century and its projected continuation. Since the early

20th century, Earth's mean surface temperature has

increased by about 0.8 °C (1.4 °F) since 1980.

scientists are more than 90% certain that it is primarily

caused by increasing concentrations of greenhouse gases

produced by human activities such as the burning of fossil

fuels and deforestation.global warming is causing rising

sea levels that occurred as the ice melted in the north.

and this is causing salt water intrusion.

What is salt water intrusion??

Page 5: Saltwater intrusion

salt water intrusion is the intrusion of salt water

over freshwater aquifers in the ground. Usually it

happen in the area that near with sea and this

could affect human activity and wildlife that

depend on fresh water in the area.

Cause of saltwater intrusion

Rising of sea water level

sea level rise caused by global warming has become a root cause, pressure from the increase in the

quantity of saltwater that many will try to enter the fresh water aquifer

high consumption of fresh water

Excessive consumption of fresh water caused a shortage of freshwater in that area and cause the waters

invaded by salt water.

oil drilling

Oil ring usually use oil pipeline under the ground to deliver oil from drilling site to storage tanks on the

beach,as the result and the more easy to salt water to insult the freshwater.

lack of rain

lack of rain causes replacement of fresh water consumption was slow while the uses are increased.in this

case it will reduce the amout of fresh water in the ground and it will be replace by sea water.

Agriculture

Agriculture is human activity that require lot amout of fresh water,it will not suitable at area that near the

sea.

Pumping

Pumping of fresh water from an aquifer reduces the water pressure and intensifies the effect, drawing salt

water into new areas.When freshwater levels drop, saltwater intrusion can proceed inland, reaching the

pumped well

Lack of knowledge

human greed for money and lack of knowledge caused us to be blind to the importance of to keep our only

living place..motherearth!!

solution build a large pool area that has been in the insult by

salt water and channeled the sea water back to the ocean, by the action the pressure of salt water near the fresh water aquifer will be reduced.

Build a pum at the area that has been insult by the salt water,pum the saltwater and channeled it back to the sea,by this action the pressure of salt water also will be reduced.

Reduced a construstion that disturb a fresh water aquaifer.

Reduced waste of fresh water near the high risk area.

Supply water from another location.

Build more catchment area

Actknowledge people about the global warming.

Effect of saltwater

intrusion The result is that when the freshwater aquifer

becomes contaminated with saltwater.

Human daily activity

Industry

Forest ecosystem

Wildlife

Everything that depent on fresh water

Page 11: Saltwater intrusion

Conclusion- This kind of pollution is less awareness of the

public. all parties, including individual organs and

even the government should care about this

problem and should take early steps to preserve

our living space only being contaminated.

- teaching about maintaining awareness of

pollution should be emphasized at all age groups.

-Groundwater is a natural resource we need to

preserve as large contribution in our daily lives.
