This study follows the geochemistry of nitrogen in a Cretaceous and unconfined sedimentary aquifer city Urânia (Brazil) over 20 years. Although sewer network was built 1970s, nitrate contamination problem (>45 mg/L-NO3−) persists to this day. The oldest urbanization areas located north initially used cesspits for wastewater currently present highest concentrations (>120 mg/L-NO3−), with plume reaching deeper portions (up 100 m). is not as dramatic south part city, where including...
Anomalous concentrations of hexavalent chromium have been detected in ground-water the Adamantina Aquifer inat least 54 municipalities located northwestern region State São Paulo, southeast Brazil, occasionallyexceeding permitted limit for human consumption (0.05 mg.L-1). An investigation was conducted municipality Urânia, where highest were regionally. It defined that originof this contamination is natural, since high aquifer sandstones (averageof 221 ppm) and also pyroxenes (6000 ppm), one...
The Pantanal of Nhecolândia, the world's largest and most diversified field tropical lakes, comprises approximately 10,000 which cover an area 24,000 km² vary greatly in salinity, pH, alkalinity, colour, physiography biological activity. hyposaline lakes have variable pHs, low macrophytes phytoplankton densities. saline pHs above 9 or 10, high a density sand beaches. cause diversity these has been open question, we addressed our research. Here propose hybrid process, both geochemical...
Os principais reservatorios de agua abastecimento da Regiao Metropolitana Sao Paulo (RMSP) encontram-se, nos dias atuais (marco 2015), com estoques proximos dos limites baixos, porem em processo leve recuperacao por conta das chuvas verao. Nestes tempos, a imprensa tem publicado diariamente situacao crise hidrica e sociedade mantem-se atonita as noticias variacoes diarias atenta discussoes sobre o racionamento que pode ou nao ocorrer algum momento ao longo 2015.
Teores anômalos e naturais de cromo ocorrem nas águas subterrâneas do Aquífero Adamantina no município Urânia (SP) em uma ampla região oeste Estado São Paulo, algumas vezes ultrapassando o limite potabilidade (0,05 mg.L-1). Visando identificar as possíveis reações geoquímicas que justificam a ocorrência na água subterrânea Urânia, foram realizadas perfurações com coleta amostras contínuas rocha para condução análises mineralógicas químicas, construídos poços monitoramento multiníveis coletas...
The integrated analysis of geophysical loggings for identifying transmissive fractures has had a limited use in Brazil, although large number studies have been conducted so far throughout the world. application those tools gained crescent importance as they are needed characterizing groundwater contamination fractured rock aquifers at great industrial sites worldwide and Brazil. This paper presents data collected by caliper, optical televiewer (OPTV), acoustic (ATV) flowmeter four deep...
Abstract In the Brazilian state of São Paulo, contaminated sites (CSs) constitute threats to health, environment and socioeconomic situation populations. Over past two decades, Environmental Agency Paulo (CETESB) has monitored these known CSs. This paper discusses produced dataset through digitising CETESB reports making them accessible public in English. The on qualitative aspects contamination within registered (e.g., type spread) their management status. data was extracted from using a...
Analises quimicas provenientes de trezentas e tres marcas aguas minerais envasadas brasileiras foram reunidas interpretadas em sua hidrogeoquimica. Este universo representa quase 50% das 672 concessoes lavra validas no pais. Estas sao, geral, baixa mineralizacao (RS<100 mg/L) baixo pH ( ≈ 6,0), fazendo parte sistemas fluxos natureza predominantemente rasa (<70m)e curto tempo trânsito aquifero. Neste contexto, destacam-se as regioes central norte do pais, que sao baixissima (RS<30 mg/L). A...
The management of contaminated areas with multiple sources contamination (megasites) is among the biggest challenges for Brazilian environmental agencies, especially because aquifers in big urban areas, like Sao Paulo Metropolitan Region, are important water human supply purposes. One main reasons that hamper proper problems a lack unified system where all information can be easily integrated into regional studies. To address this problem, method data integration and using Geographic...
The investigation of contaminated areas in fractured aquifers represents a great technical challenge, due to the frequent conditions heterogeneity and anisotropy these environments, which often make it difficult identify predict pathways subsurface contamination. This work aims contribute development this subject, through presentation results an geophysical logging tools straddle packers were used, allowed more suitable hydrogeological conceptual model study area. Two boreholes drilled...
A análise detalhada de estruturas rúpteis é uma ferramenta ainda pouco utilizada no estudo aquíferos fraturados, apesar ser complementar aos dados obtidos em poços e fornecer elementos grande relevância para a elaboração modelos conceituais fluxo água subterrânea. Este trabalho apresenta coletados pedreiras do Complexo Embu, visando elaborar modelo geométrico fraturas granitos gnaisses pré-cambrianos, modo subsídios projeto mais amplo caracterização contaminação por solventes organoclorados...
Por que as aguas subterrâneas sao ‘tao importantes a saude da populacao? No Brasil, abrir uma torneira nao garante obter agua potavel. Embora seja essencial para populacao, atencao publica em saneamento ainda e deficiente. acesso esgoto, o Brasil ocupa 112o lugar entre 200 paises cobertura rede nacional de 83%. Entretanto, este numero esconde deficiencia maior, pois ter sua casa ligada [...]
This study aims to analyze the degree of isolation natural lakes with unusual values salinity and pH in area Pantanal da Nhecolândia, largest field tropical zone planet. process is still poorly understood essential for understanding entire environment. The was measured by electrical conductivity shows great variations. possibility important variability evaporation or precipitation dismissed because are same region flat. Therefore, differences may be associated a present processes, provided...
Three hundred and three labels of bottled mineral water from different sources were collected analyzed in terms their hydrogeochemistry. This total represents almost 50% the 672 operation country. In general, Brazilian waters are low mineralization (TDS<100 mg/L) pH around 6,0, denoting groundwater flow rapid shallow systems (<70m). Waters central northern regions country deserve special mention, once they show an extremely degree (RS<30 mg/L). The main geochemical phenomena determining type...
