Groundwater Vulnerability to Pollution in Urban Catchments

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...

Providing DRASTIC maps to assess potential vulnerability in Kohnak aquifer using GIS

Nowadays the study of regional groundwater resources, because of draught ,their optimal exploitation,and reducing their pollution is a vital matter. A proper way to prevent the pollution of undergroundwaters is to locate vulnerable spots and to conduct an efficient exploitation of the ground. Using thepresent models is very essential to locate and study about vulnerable spots. For this study, G...

Assessing the vulnerability of groundwater sources to fecal contamination

The Honolulu Board of Water Supply (HBWS) selectively chlorinates half of its groundwater supply to provide drinking water that meets the Total Coliform Rule. The objective of this study was to determine whether the groundwater sources used by HBWS are vulnerable to contamination with fecal matter and would require routine disinfection. Larger volumes (1,000 mL) of samples from groundwater and ...
