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

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

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

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

Source From where? underground surface

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

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.

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?

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
