The mathematical modelling of total nitrogen contamination transport via groundwater from a sugar factory in Eskisehir, Turkey
In this study, mathematical modelling of the total nitrogen contamination transport in a porous medium was evaluated in order to determine the potential groundwater pollution caused by a sugar factory in the Eskisehir region of Turkey. Analytical solutions of mathematical modelling were performed to show graphically the distributions of contaminant concentrations. Multiflow computer programming ...

Investigation of contaminant transport in groundwater from the tailings pond of uranium mine: a case study
The present study investigates the spreading of radioactive materials through groundwater by developing a groundwater contaminant transport model. The model was analysed in the steady state, and was then applied in the transient state to predict the spreading of uranium and its daughter product in the region. The model was verified using the simulated and measured velocity of groundwater. It was ...

Integrated fuzzy framework to incorporate uncertainty in risk management
Integrated Fuzzy Relation Analysis (IFRA) model is proposed for risk assessment involving multiple criteria. The model is an integrated view on uncertainty techniques based on multi-valued mappings, fuzzy relations and fuzzy analytical hierarchical process. Integration of system simulation and risk analysis using fuzzy approach allowed incorporating system modelling uncertainty and subjective ...

New Jersey Uses GIS, EQuIS to Collect Site Remediation Data
Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the evaluation ...

State-wide collection of site remediation data in support of environmental quality objectives
Geographic Information Systems (GIS) hold great potential as a tool for managing environmental site remediation data. While noting the location of contaminated sites in GIS is commonplace, GIS has played only a minor role in review and analysis of chemical data gathered during an investigation or monitoring activity. The New Jersey Department of Environmental Protection Site Remediation Branch ...

Estimating contaminant-flushing rates for heterogeneous aquifers
Groundwater remediation evaluations typically include cleanup time projections. Current batch flushing-rate equations and analytical models often used to estimate groundwater cleanup rates typically underestimate cleanup times, with a major factor the flawed assumption of aquifer homogeneity. Numerical modelling of groundwater flow and contaminant transport is a time-intensive and costly ...

The Influence of an Integrated Remedial System on Groundwater Hydrology
ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...

Evaluating Cleanup at Hamilton Army Airfield Using EQuIS and ArcGIS
The Sacramento District, US Army Corps of Engineers, is implementing EarthSoft's EQuIS and ArcGIS for better management, analysis, and response to landfill remedial activities being conducted at the former Hamilton Army Airfield. This former Air Force Base located four miles south of the city of Novato, on San Pablo Bay, in Marin County, California, is undergoing environmental clean-up as it is ...
