INTEGRATED AQUIFER VULNERABILITY ASSESSMENT OF NITRATE CONTAMINATION IN CENTRAL INDIANA
… groundwater management plans is assessment of aquifer risk using computational models. Groundwater modeling with a geographic information system (GIS) for efficient groundwater management can provide maps of regions where groundwater is contaminated or may be vulnerable and also can help select …

Assessing Aquifer Vulnerability to Seawater Intrusion : Application of the GALDIT-Index to the Emilia-Romagna Coastline.
Saltwater intrusion (SWI) in coastal aquifers due to excessive groundwater withdrawals (for civil, agricultural and industrial purposes) has become a major concern affecting a large number of coastal aquifers worldwide. This trend is expected to grow in the very near future due to the expected …

The Use of Radionuclides to Identify Vulnerable Fractured and Karst Bedrock Aquifers in Eastern Ontario
… vulnerable fractured and karst bedrock aquifers using geologic and geochemical data. A novel methodology is presented that evaluates ¹³⁷Cs and ²¹⁰Pbₑₓ as local indicators of groundwater vulnerability. The method is designed to determine the vulnerability of a specific well. Suspended …

Evaluating Sources of Arsenic in Groundwater in Virginia using a Logistic Regression Model
For this study, I have constructed a logistic regression model, using existing datasets of environmental parameters to predict the probability of As concentrations above 5 parts per billion (ppb) in Virginia groundwater and to evaluate if geologic or other characteristics are linked to elevated As …

Adjustment of DRASTIC vulnerability index to assess groundwater vulnerability for nitrate pollution using the advection diffusion cell
This study aims to estimate aquifer vulnerability by applying the standard DRASTIC index as well as utilizing the Emission-Transmission-Immission (ETI) concept to assess the groundwater vulnerability to groundwater contamination by nitrate in a part of the Venlo Block (German name: Venloer Scholle) …
