Several natural indicators of radial well ageing at the Belgrade Groundwater Source, part 1
Over time, the radial collector wells of the Belgrade Groundwater Source, located in the alluvial sediments of the Sava River, exhibit a decline in discharge and a reduction in operating efficiency due to well ageing. An increase in hydraulic losses at the lateral screens, due to chemical and biochemical clogging, has been identified as the primary cause. Certain hydrogeological, hydrochemical ...

Surveying for 600-Meter-Deep Groundwater in Kenya - Case Study
The importance of groundwater can’t be overstated. It’s crucial for life across the globe, and, in the developing world, access to groundwater is at a premium. However, with resistivity imaging groundwater exploration techniques, even when you’re in one of the driest locations on Earth, deep groundwater is possible to locate. In 2006, our client, the Engineers Brigade of the ...

Spatio-temporal variation of groundwater contamination using IEA-UEF in urban areas of Jilin City, North-eastern China
Groundwater monitoring wells located in urban areas of Jilin City were sampled from 1980 to 2009 for eight groundwater quality parameters: pH, SO42−, Cl−, NO3−-N, NO2− -N, NH4+-N, F−, and total hardness (TH). The data were analysed by a universal exponential formula based on an immune evolutionary algorithm, and later mapped with the Kriging interpolation method. The primary objectives were ...

Searching for Potential Unmarked Graves Near San Antonio, Texas - Case Study
Our client, Terracon, used AGI tools and software in order to identify whether or not there were unmarked graves near a family cemetery and a known historical site for homesteaders near San Antonio, Texas. Process Our client was interested in mapping an area being developed near a cemetery that dated back to 1899. The client used the SuperSting R8/IP, the SwitchBox 112, and 112 electrodes ...

Georgetown Water Treatment Plant
Georgetown, in the Town of Halton Hills, is supplied by nine groundwater wells located in four well fields. The Region of Halton has received many colored water complaints from customers over the past several years. In order to ensure high quality water to the customers in Georgetown, the Region of Halton retained XCG Consultants to complete two projects. The projects included a study to identify ...

Self-organizing map clustering technique for ANN-based spatiotemporal modeling of groundwater quality parameters
The present study integrates co-kriging as spatial estimator and self-organizing map (SOM) as clustering technique to identify spatially homogeneous clusters of groundwater quality data and to choose the most effective input data for feed-forward neural network (FFNN) model to simulate electrical conductivity (EC) and total dissolved solids (TDS) of groundwater. The methodology is presented ...

Construction Aggregate Mining: Sand and Gravel - Case Study
In 1995, we helped a company locate sand and gravel volumes in San Marcos, Texas. This material can be mined and sold for construction purposes. Process The Sting R1 with 47 Dual-Mode Swift electrodes was spaced three meters apart. Two parallel lines were collected eight meters apart to identify conductive silt/clay/shale and resistive sand/gravel areas. Results Sand and gravel zones and ...

Feasibility study of in-situ bioremediation for nitrobenzene-contaminated groundwater
Although many studies have simulated in-situ bioremediation of contaminated groundwater, most of them have not considered hydrochemical conditions and indigenous microorganisms, thus potentially rendering results inapplicable to actual in-situ groundwater bioremediation projects. This study focused on a nitrobenzene-contaminated groundwater site located in Jilin City, China. The actual ...

Groundwater and stream E. coli concentrations in coastal plain watersheds served by onsite wastewater and a municipal sewer treatment system
The goal of this study was to determine if onsite wastewater treatment systems (OWS) were influencing groundwater and surface water Escherichia coli concentrations in a coastal plain watershed. Piezometers for groundwater monitoring were installed at four residences served by OWS and five residences served by a municipal wastewater treatment system (MWS). The residences were located in two ...

EQuIS milestone
EQuIS now contains over 15 million chemical/physical discrete monitoring results after the recent completion of the EDMS (Closed Landfills) database migration. Growth for other MPCA Remediation and Solid Waste programs will depend on the rate that labs and contractors adopt the new standard lab and field EDD submittal formats and on associated location establishment. Groundwater and surface water ...

Locating Groundwater Wells for Fracking Operations in West Texas - Case Study
In June 2014, our clients used AGI resistivity imaging tools to successfully locate a 125-gallon-per-minute groundwater well in West Texas as well as geohazards that could, if left unlocated, cause significant damage to property and increase costs. Process Our clients used the SuperSting R8 Wi-Fi with a SwitchBox 112, passive cables spaced at six meters apart, and a dipole-dipole and strong ...

The Use Of Innovative Groundwater Seepage Detection Techniques - Case Study
INTRODUCTION Groundwater seepage can exacerbate environmental pollution through contaminant transport, pose a threat to dam safety and can also be associated with valuable mineral deposits. Dam safety, environmental remedial works and mineral location normally involve comparatively expensive techniques, but, if the extent and location of groundwater seepage can be accurately predicted, then the ...

Incorporating site-specific analytical data and machine learning to predict environmental site conditions
EnviMetric makes intelligent predictions about the extent of groundwater contamination even when there is no available analytical data regarding contaminant concentrations. Factors such as the site location, release type, property use, and geologic setting are very predictive of how large a groundwater plume will be. EnviMetric uses all this available information to make data-based predictions ...
