The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...

Onsite wastewater treatment systems (OWTS), or septic systems, can be a significant source of nitrates in groundwater and surface water. The adverse effects that nitrates have on human and environmental health have given rise to the need to estimate the actual or potential level of nitrate contamination. With the goal of reducing data collection and preparation costs, and decreasing the time re...

Over the past 30 years, tubewells have become a ubiquitous source of potable groundwater in South Asia. Considered safer than surface water, groundwater naturally contains minerals that may impact human health; however, few data exist on tubewell water mineral content or its association with human nutritional or health conditions. We surveyed iron concentration in tubewell water across a 435 km...

To demonstrate the capabilities of Geographic Information System (GIS) techniques and numerical modeling for groundwater resources development in arid areas, specifically for the demarcation of suitable sites for the artificial recharge of groundwater aquifers, a study was carried out in the Maknassy basin, which is located in Central Tunisia. Thematic maps were prepared using a Hydrogeological...

The main objective of the present study is to investigate the hydrogeology of the Jalakandapuram sub – basin, groundwater potential and quality of groundwater for domestic, industrial and agricultural purposes. Jalakandapuram ( Latitudes 11° 35‟30‟‟N to 11°46‟25‟‟N and Longitudes 77°48‟30‟‟ E to 78°2‟E) Subbasin is one among the four subbasins of the Sarabanga minor basins which comes under the...

Increasing pressure on water supply worldwide, especially in arid areas, has resulted in groundwater overexploitation and contamination, and subsequent deterioration of the groundwater quality and threats to public health. Environmental risk assessment of regional groundwater is an important tool for groundwater protection. This study presents a new approach for assessing the environmental risk...

Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...
