Simposio: Contamination and restauration of aquifers
(Universidad Autónoma del Estado de México, 2014)
Modeling of hydrochemistry evolution in carbonatic–siliciclastic aquifer system in coastal environment
(2021-08-01)
Coastal regions are quite populous, causing coastal aquifers to be overexploited, due to which contamination of these aquifers is observed. The municipality of Belém, located on the eastern edge of the Amazon Forest, is ...
Nitrates in groundwater of the state of São PauloNitrato em águas subterrâneas do estado de São Paulo
(2019-01-01)
As groundwater consumption increases, its quality and consequently its potability are proportionally affected. Nitrates stand out among the agents that contribute to the loss of groundwater potability, as they are the most ...
DC resistivity investigation in a fractured aquifer system contaminated by leachate from an old dump
(Inst Geophysics Unam, 2017-10-01)
The dumps are areas of final disposal of solid wastes directly into the soil, with no technical criteria or collecting systems of gases or liquids. A large part of Brazilian municipalities have used this extreme damaging ...

Electrical resistivity tomography (ERT) applied in the detection of inorganic contaminants in suspended aquifer in Leme city (Brazil)
(2017-01-01)
The assessment of contamination caused by improper disposal of solid waste involves integrated analysis of the physical environment, which shall range from the location of the pollutant source, flow paths and accumulation ...
Detection of groundwater and soil contamination by hydrocarbons using radon as a tracer
(2015-04-01)
Subsurface contamination with hydrocarbons as non-aqueous phase liquid (NAPL) is one of the most common environmental impact associated with fuel leak in gas station areas and can represent a health human problem due to ...
Using surface downhole ERT for detecting contaminants in deep aquifers due to the exploitation of oil reservoirs
(European Association of Geoscientists & Engineers, 2018-02)
The exploitation of a hydrocarbon reservoir, whether conventional or unconventional, may cause environmental damages. Even though sink wells used by oil companies are located much deeper than aquifers, they may eventually ...
Análise de metais pesados no Sistema Aquífero Bauru em Mato Grosso do Sul
(2017-01-01)
Heavy metals are contaminants of great concern in the aquifers due to their toxicity at certain concentration and difficult remediation. This study aimed to analyze the concentrations of Cu, Cr, Fe, Mn and Zn present in ...
SDR: A new method to assess the natural vulnerability to contamination of granular unconfined aquifersSDR: Um novo método para avaliar a vulnerabilidade natural à contaminação de aquíferos livres granulares
(2019-01-01)
In view of increase in the number of contaminated areas, which compromise the groundwater quality and constitute risks to human health, it is essential to establish instruments for land use planning and management, aiming ...
