A BRIEF REFERENCE ABOUT FRESH AND SALT WATER WORLDWIDE AND IN CUBA

Abstract

Though many water testing have been produced worldwide and in Cuba, there are not yet deep studies of how fresh and salt water behave and how they can be compared according to some chemical parameters. This kind of study is very useful to characterize the quality of water in some regions of Cuba where human activity is frequently present. This paper becomes a starting point of a series of water testing that will be carried out after analyzing the situation of water quality and the implication this water has to human health and socioeconomic activity. The objective of this work is to reveal the potentials, weaknesses about fresh and salt water worldwide and specifically in Cuba. To meet this goal, the authors have confirmed their criteria through a practical experiment based on 5 indicators: Dissolved Oxygen, water temperature, pH, Phosphates and Nitrates. This comparison has been the base for determining which are the main causes that have provoked water disruption in some lakes, rivers, dams and several beaches. In this research several University students have participated, whose activity and reflection have been part of their outdoor formation and the permanent link between school and community.
