Qualidade da Água da Lagoa do Parque Sólon de Lucena

Abstract

Population growth has provided an increase in demand for the use of water resources, and this is characterized as one of the main factors responsible for the pollution of water bodies. The Sólon de Lucena Park, which is known by the population as a lagoon and is located in the capital of Paraíba, João Pessoa, is an area of importance, as it is considered a municipal historical symbol. Eutrophication is recognized as one of the most important water quality problems today. Phosphorus is seen as an important pollutant of aquatic environments, especially in surface waters, in large concentrations of phosphorus in water there is favoring the growth of algae and macrophytes that in the future may interfere with the use of water. Its relevance is due to the fact that phosphorus is an essential nutrient for plant growth in, in water bodies, in most cases it is the limiting factor of this process, that is, available phosphorus is one of the factors that are most important in regulating of the efficiency of the system. The Water Quality Index (WQI) is a methodology that is used to evaluate the quality of raw water based on physical, chemical and biological characteristics, classifying them based on established quality parameters. In this study, the Trophic State Index (TSI) will be calculated based on the phosphorus values, using the methodology of LAMPARELLI (2004) and the WQI will be calculated based on the CETESB/ANA method.
