8. At the end of this lecture the student will be able to:
1. Identify the different water sources
2. Describe the advantages and disadvantages of
groundwater
3. Identify surface water sources
4. Describe the importance of rainwater
5. Describe the disadvantage of ocean water

9. Lecture # 1 SOURCES OF WATER
Groundwater(wells and springs)
Surface Water
Rainwater
Ocean Water

10. Disadvantages of groundwater
free from disease causing micro-organism.
can be used without further treatment.
Disadvantages of groundwater
A. It needs pumping unless it comes from a spring
B. It may contain excess amounts of dissolved minerals.
C. It is poor in oxygen content

11. Occurrence of groundwater
perched water
free water
confined water.
Compare between the above

12. Source
From where?
underground
surface

13. Compare between the above
Types of wells
Shallow wells
Deep wells
Artesian wells
Springs
Compare between the above

16. Surface Water includes: rivers, streams, lakes, ponds, etc.
Rainwater :In regions where rainfall is abundant and frequent, rainwater can be a good source of water supply for individual families and for small communities(not in large scale)
Ocean Water r:To make the ocean water fit for these purposes; it must pass through a process known as desalination (a process of removal of salt from water). However, it is too expensive to consider.

17. Review Questions
1-List the types of ground and surface water sources?
2-What is the advantage and disadvantage of groundwater?
3-What is the significance of rainwater?
4. What is the disadvantage of ocean water?

18. Testing Water Quality Water quality parameters often tested are:
Dissolved oxygen
Water temperature pH
Total Ammonia Nitrogen
Nitrite/Nitrate
Alkalinity/Hardness
Salinity
Water test kit
