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??
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.
Government policy
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
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.
