A Bacia Sedimentar do Paraná tem posição de destaque, em nível nacional, com relação a sua potencialidade para recursos hídricos, por abrigar várias unidades produtoras, com ênfase no Sistema Aqüífero Guarani (SAG). O presente estudo representa uma aplicação do método de análise de bacias para caracterização dos sistemas aqüíferos Botucatu, Serra Geral, Caiuá e Bauru, todos de idade mesozóica, no Planalto Ocidental Paulista. Com base na integração de informações provenientes de poços tubulares profundos, mapas estruturais, mapas e seções estratigráficas, foi possível apontar áreas favoráveis a execução de projetos para exploração de água subterrânea, de acordo com as características geológicas de cada área identificada nesta província geomorfológica do território paulista. Palavras-chave: Bacia Sedimentar do Paraná; Sistema Aqüífero Guarani; Planalto Ocidental Paulista; Exploração de Água Subterrânea.

This work evaluated the natural and anthropogenic influences on the quality of groundwater from public supply wells in the urban area of Marília, São Paulo State. Sixteen sampling points were established in the Adamantina Aquifer, Bauru Aquifer System, analyzing the following parameters: electrical conductivity, temperature, pH, total suspended solids, HCO3 - , PO4 3-, SO4 2-, Cl- , F- , N-NO3 - , Ca2+, Na+ , K+ , Mg2+, Si4+, Fe3+ and Al3+. The results indicated that the groundwater in the urban area of Marília has a slightly acid pH and low conductivity, with the ionic composition presenting a low cation and anion concentration and is classified as soft water and calciumbicarbonated water. Natural sources of elements/compounds can be attributed to the dissolution of carbonates during the water/rock interaction, controlling pH, alkalinity and electrical conductivity, and hydrolysis of other mineral constituents of sedimentary rocks from Adamantina Formation, with the exception of quartz. High concentrations of N-NO3 - found in some public supply wells in urban Marilia were due to sewage.

The use of geophysical methods in the analysis and mapping of likely contamination plumes has shown a huge value in the development of researches related to environmental issues. Among the main geophysical methods applied to this purpose, the geoelectrical methods stand out, being based on the use of electric and electromagnetic fields. The electromagnetic method (EM) uses physical environment responses created by electromagnetic field propagation, consisting of an alternated electric output and a magnetization force, used to obtain the electric conductivity (σ) of the subsurface materials. It has a broad application in the mineral exploration and prospection, and its use has been also efficient in environmental researches. By the electromagnetic method, this work examined and mapped possible contaminations created by cemetery leachate in the Saudade's Cemetery, located in the city of Monte Alto, Sao Paulo, where sedimentary rocks of the Bauru Group are exposed. Cemetery leachate is a putrefactive liquid, generated from the decomposition of organic matter, which contains substances that can contaminate soil and groundwater. Results achieved in this work show that the use of the electromagnetic method is an important indirect tool in the investigation of environmental contaminations in areas with highly contrasting physical properties

The collection of prices for basic goods supply is very important for the population, based on the collection and processing of these data the CLI (Cost Living Index) is calculated among others, helping consumers to shop more rationally and with a clearer view of each product impact of each product on their household budget, not only food, but also cleaning products and personal hygiene ones. Nowadays, the project of collection of prices for basic goods supply is conducted weekly in Botucatu - SP through a spreadsheet. The aim of this work was to develop a software which utilized mobile devices in the data collection and storage phase, concerning the basic goods supply in Botucatu -SP. This was created in order to eliminate the need of taking notes in paper spreadsheets, increasing efficiency and accelerating the data processing. This work utilized the world of mobile technology and development tools, through the platform".NET" - Compact Framework and programming language Visual Basic".NET" was used in the handheld phase, enabling to develop a system using techniques of object oriented programming, with higher speed and reliability in the codes writing. A HP Pavilion dv3 personal computer and an Eten glofish x500+ handheld computer were used. At the end of the software development, collection, data storing and processing in a report, the phase of in loco paper spreadsheets were eliminated and it was possible to verify that the whole process was faster, more consistent, safer, more efficient and the data were more available.
