Assessment of groundwater vulnerability to nitrate pollution caused by agricultural practices

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...

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...

Spatial assessment of animal manure spreading and groundwater nitrate pollution.

Nitrate concentration in groundwater has frequently been linked to non-point pollution. At the same time the existence of intensive agriculture and extremely intensive livestock activity increases the potential for nitrate pollution in shallow groundwater. Nitrate used in agriculture could cause adverse effects on human and animal health. In order to evaluate the groundwater nitrate pollution, ...

Groundwater Vulnerability to Pollution in Urban Catchments

Groundwater vulnerability to pollution mapping of Ranchi district using GIS

Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The present study demonstrates the integrated approach with GIS and DRASTIC model to derive a groundwater vulnerability to pollution map. The model considers the seven hydrogeological factors [Depth to water table (D), net recharge (R), aquifer media (A), soil media (S...
