“…The contamination of the aquifer depends on factors like the depth to the aquifer, concentration of contaminants, and permeability of subsurface layers, geological setting and the direction of groundwater flow (11)(12)(13) . In determining the quality of groundwater, the geochemical or biogeochemical mineral composition of aquifer rocks and groundwater flow are considered.…”

Aim/objectives: This research is geared towards integrating Vertical Electrical Soundings (VES) and Electrical Resistivity Tomography (ERT) profiles constrained with geoelectric sections and borehole logs to assess the vulnerability of the aquifer units employing Aquifer Vulnerability Indexing (AVI) method. Method: The dataset used in this study comprises of fifty VES, five ERT profiles surveyed in parts of Enugu north in Enugu state, two geoelectric sections and three borehole logs. The computer and manual interpretation of VES resistivity data using WinResist software gave values of resistivity, depth and thickness of each geoelectric layer using half current electrode spacing of 1.0 to 450.0 m and maximum current electrode spacing of 900 m. 2D imaging data from the measured field resistance values were processed using RES2DINV×32 version 3.71.115 software. The geoelectrical sections show the variation of resistivities with depth along transcent lines. The geohydraulic parameters were also estimated. Finding: Interpreted VES data revealed five to six geoelectric layers and fundamental parameters generated were used to estimate the values of hydraulic conductivity (σ) and hydraulic resistance (C) of the covering layers ranging from 0.010 to 0.769 mday −1 and 40.47 to 8292.0 day −1 respectively. This research revealed high hydraulic conductivity in the western part implying good groundwater potential with moderate to high protective capacity while areas with low hydraulic conductivity correspond to areas with high resistivity indicating little or no pore space and total devoid of water. The hydraulic resistance quantifies groundwater vulnerability using AVI and reveals that the area of study is characterized by low to high AVI with moderate AVI dominanting. Originality and novelty: The estimated geohydraulic properties from resistivity data and their spatial spread are promising and could increase the depth of knowledge on groundwater vulnerability within and around the study area.

“…This possibly indicates much higher contamination of groundwater in that area, as the water rich in electrolytes has much smaller electric resistance than pure water. This phenomenon was used by other researchers to study for example the extension of the leachate contamination plume area [24]. VES survey also indicated the presence of clay lens in SP-1050 (area with very low resistivity Pa = 8 Ω·m).…”

Ocena oddziaływania lagun osadowych na jakość środowiska wodnego w ich otoczeniuThe main goal of this research was to determine the impact of sludge lagoons collecting sewage sludge from the wastewater treatment plant in Almaty (Kazachstan), on groundwater and surface water quality. After geophysical examination of the study area (including Vertical Electroresistivity Survey and Seismic Survey), there were set three sampling points for examination of groundwater quality, and 2 points for sampling water from the river Almatynka Bol'shaya, winding 250÷500 meters from the borders of lagoons. The results obtained from the analysis of collected samples showed high concentrations of Fe, Mn, Zn, PO4 ions and other compounds in groundwater in the vicinity of sludge lagoons. It was also found that in the river section downstream sludge lagoons there were higher concentrations of heavy metals and other contaminants, than in the river section upstream.

“…Para garantir a adequada gestão dos resíduos, a Lei 12.305, de 2010, que instituiu a Política Nacional dos Resíduos Sólidos (PNRS), impôs a destinação final ambientalmente adequada para os rejeitos em aterros sanitários (BRASIL, 2010). No entanto, as áreas de disposição de resíduos são fontes potenciais de contaminação do meio ambiente, necessitando de monitoramento contínuo, mesmo quando construídas e operadas seguindo normatizações (LOPES et al, 2012).…”

A disposição nal dos resíduos sólidos urbanos deve ser realizada em aterros sanitários e, para analisar a operação desses aterros, a Companhia Ambiental do Estado de São Paulo desenvolveu o Índice de Qualidade de Aterro de Resíduos que, com um check list, avalia as características locacionais, operacionais e estruturais. O presente estudo teve como objetivo adaptar a metodologia às leis ambientais do Paraná e aplicar o índice no aterro municipal de Francisco Beltrão. Os dados foram coletados in loco, registrando-os por meio de fotogra as e por entrevistas semiestruturadas aplicadas aos funcionários do aterro. Além do levantamento da documentação do aterro junto à Secretaria Municipal de Meio Ambiente, as características físicas foram mensuradas em Sistema de Informação Geográ ca. O aterro foi enquadrado como inadequado, com o índice 5,2. Portanto, são necessárias adequações, sobretudo nos parâmetros que obtiveram menor pontuação, como a cobertura diária dos resíduos, a drenagem e o tratamento do chorume.
