A. Indonesia’s Water Supply Problems

Indonesia water resources accounted has for almost 21 percent total water resources in the Asia Pacific region

The availability of clean water in term of quantity tends to decrease due to environmental degradation and pollution.

At least 80 percent of 250 millions Indonesian has no access to piped water

Most of river water quality does not meet drinking water criteria. There is only 21 percent of samples meet the drinking water criteria.

B. How do We Detect Water Pollution

Water pollution is detected in laboratories, where small

samples of water are analyzed for different contaminants.

Living organisms such as fish can also be used for the

detection of water pollution. Changes in their behavior or

growth show us, that the water they live in is polluted.

C. Factors that cause Water Pollution

Human Activities :

Domestic waste56.15 percent of household disposes their domestic waste directly to river body.

Industrial activities Industrial activities wastes water such as small scale industries, agriculture, textile, pulp and paper, petrochemical, mining, and oil and gas

Air PollutionSubstances that pollute the air will pollute water through the water cycle

Natural :

Volcanic activities (i.e.: Sulfur, cold lava dan thermal pollution)

D. Health Impact of Inadequate Water Supply

Disease can spread through polluted water The food chain is damaged Acid rain Marine food sources are contaminated

E. Dealing with Water Pollution (1)

Dealing with water pollution is something that everyone needs to get involved with. Here are a few things you can do to help :

- Learning about the issue - Never throw rubbish away anyhow. - Use water wisely. - Do not throw chemicals, oils, paints and

E. Dealing with Water Pollution (2)

The government had done some programs to solve our country’s water supply problems. Those are:

Clean River programme (PROKASIH) by Ministry of Environment Indonesia (KLH)

Watershed (DAS-Daerah Aliran Sungai) Rehabilitation Programme by Ministry of Public Works Indonesia (PU)

Reforestation of watershed and upstream of the river by the Ministry of Forestry

Conclusion

Water pollution in Indonesia occurred on the rivers,

lakes, sea, and groundwater which caused by degradable

waste and undegradable waste

A better water supply systems provides the foundation of

a prosperous community

Dealing with water pollution is something that everyone,

including governments and local councils, needs to get
