Water Quality and Pollution Assessment

The increase in population, coupled with disorderly urbanization processes, is responsible for much of the pollution of water bodies.The beaches of Mosqueiro Island (Belem, PA) provide one of the main leisure options of the local population and therefore they deserve special attention.This study evaluates water quality through the use of a water quality index and trophic state.The data obtained included abiotic parameters, chlorophyll a, and total/ fecal coliforms.The data showed the influence of seasonality and tide on water quality, especially during less rainy periods, which was reinforced by the analysis of principal components.The results of the water quality index were close among the two previous period studies.The trophic state index showed that the environment is not eutrophic.This information provides local managers a current analysis of water conditions in the study area.
