The course provides basic tools to understand the needs and importance to assess water quality. This will be based on the hydrological cycle of water and the possible sources of contaminantion. The key issue is to understand water quality in the broad context of integrated water resources management.

The present course aims to achieve the following learning outcomes:

• Familiarize students with the three main classes of water pollutants and their widespread relevance, in particular why are arsenic, bacteria, fluoride and uranium called the ‚four killers‘?

• Recall the basic principles of water chemistry used in water treatment, including their limitations,

• Insist on the need to avoid using harmful disinfection agents by non-skilled persons. In particular, the evidence that chlorination is not an appropriate approach for decentralized systems.

• Recall the main types of chemical reactions and their application water treatment while insisting that physical methods are unavoidable for safe drinking water.

• Discuss business opportunities based on Water Quality (e.g. creating laboratories, consultancy).

• Develop a sense of critical thinking about available analysis report of water samples based on the Principle of Electroneutrality.

• Overall, students are empowered to overcome the major flaws of the modern African education system and become competent partners in discussing the importance of Clean Water for Public Health in a holistic manner.

The Learning Outcomes as per PAUWES syllabus will be achieved the better, the more the lectures are interactive. So please, participate with comments, questions, and remarks. In this way, we will better link individual issues to the overall picture!
