Drastic method to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas

modification of drastic model to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas

drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...

Agricultural Impact on Groundwater Vulnerability to Nitrate in Northern Croatia

Th ere is noticeable negative impact on soil and water quality caused by nutrient leaching, especially nitrate. Five regions in Croatia are preliminary delineated as nitrate vulnerable zones, including potentially vulnerable zones (PVZ) and vulnerable zones (VZ), one of them being Varaždin County. Agricultural land spreads on 59% of its total area. Th e survey was carried out to analyze two ava...

Assessing the groundwater vulnerability to pollution using DRASTIC and SINTACS models, case study: Evan Plain, south west of Iran

Optimization of DRASTIC method by artificial neural network, nitrate vulnerability index, and composite DRASTIC models to assess groundwater vulnerability for unconfined aquifer of Shiraz Plain, Iran

BACKGROUND Extensive human activities and unplanned land uses have put groundwater resources of Shiraz plain at a high risk of nitrate pollution, causing several environmental and human health issues. To address these issues, water resources managers utilize groundwater vulnerability assessment and determination of protection. This study aimed to prepare the vulnerability maps of Shiraz aquifer...
