TITLE:

SUMMARY:

Water bodies are fundamental for the well-being of the population, especially regarding the water need of the human body, as well as other biotic individuals. The PIJ watershed (Peruípe, Itanhém and Jucuruçu) bathes the extreme south of Bahia, with the Itanhém River being the most extensive water body, also called the Alcobaça River, whose source is located in the State of Minas Gerais and its mouth in the municipality of Alcobaça/BA. The use and occupation of the soil is crucial for the maintenance or alteration of the physical and chemical properties of the water, being the human action the main agent of degradation, interfering in the bathing of the water bodies. The objective of the present work was to determine the Water Quality Index - WQI, in a stretch of the Itanhém river, between the municipalities of Teixeira de Freitas and Alcobaça, in its temporal and spatial variations, as well as its framing in line with the CONAMA Resolution No. 357/2005. For this purpose, samples were collected at seven strategically chosen points, according to possible sources of pollution and contamination, and the physical-chemical variables necessary to obtain the WQI were identified (pH, turbidity, electrical conductivity, total dissolved solids, salinity, temperature, dissolved oxygen, total phosphorus and total nitrogen) and microbiological (total and thermotolerant coliforms), following the analytical methods described in the Standard Methods for Examination of Water and Wastewater, adapted by CETESB. Furthermore, the classification of images in the area of direct influence (buffer) of the sampled points was carried out to obtain the characterization regarding the use and occupation of the soil, inferring its relationship with the quality of the analyzed water body. With the values of the physical-chemical variables, the Water Quality Index is obtained, as well as the water situation and its bathing properties. The results will be published through articles, as well as made available to Public Management Bodies, in order to guide actions in relation to water resources and sanitation.
