Article Synopsis
  • * The analysis of groundwater samples showed a slight alkalinity, with 62% being affected by seawater, and the presence of ions indicated serious saline contamination, as evidenced by various hydrochemical and mineral dissolution indicators.
  • * Health risks were highlighted by elevated total hazard index values for nitrate and fluoride, suggesting that seawater intrusion is increasing over time in certain parts of the study area, particularly along the west coast.

The impact of seawater intrusion from coast to inland terrain in the Cauvery River Basin (CRB) and Uppanar River Basin (URB) was evaluated based on major ion groundwater chemistry. TDS ranges from 229 to 2260 mg/l, and 408 to 3732 mg/l; Na range from 67 to 560 mg/l, and 74 to 1600 mg/l, and Cl range from 120 to 906 mg/l, and 110 to 3260 mg/l for CRB and URB respectively. Piper Diagram, Hydrochemical Facies Evolution Diagram (HFE-D), rock-water interaction (Gibbs Plots), various bivariate plots viz.

Evaluation of groundwater chemistry and its related health hazard risk for humans is a prerequisite remedial measure. The semi-urban region in southern India was selected to measure the groundwater quality to know the human health risk valuation for different age groups of adults and children through oral intake and skin contact with elevated concentrations of fluoride ([Formula: see text]) and nitrate ([Formula: see text]) groundwater. Groundwater samples were collected from the semi-urban region for pre- and post-rainfall periods and resolute its major ion chemistry.

The research objective is to assess the Mahi River basin, morphometric parameters, and structurally controlled morphological terrains about the topsoil grain size index (TGSI), based on satellite data including Landsat 8 OLI/TIRS and SRTM-DEM data, using ArcGIS processing software. According to morphometric analysis, the Mahi River basin has an area of 28,844.2 km and is a drainage basin of the 8 order.

Purpose: Presence of heavy metals in Peenya industries is considered a major environmental and human health risk. The purpose of this research is to determine the concentrations of trace elements in urban industrial soils in north Bengaluru in order to assess the degree of soil pollution and to evaluate environmental and human health risk.

Methods: Twelve soil samples during July-2016 were taken from Peenya industrial sites at different depth viz.

Evaluation of groundwater quality and related health hazards is a prerequisite for taking preventive measures. The rural region of Telangana, India, has been selected for the present study to assess the sources and origins of inferior groundwater quality and to understand the human health risk zones for adults and children due to the consumption of nitrate ([Formula: see text])- and fluoride (F)-contaminated groundwater for drinking purposes. Groundwater samples collected from the study region were determined for various chemical parameters.

The pre-Cambrian chromites ore deposits in Sukinda valley, Jajpur District, Orissa, India, are well known for chromite ore deposits. The exploitation of the ore is carried out through open cast mining method since the last few decades. In the process, the overburden and ore dumps are stored on ground surface, where leaching of chromite and other toxic element takes place particularly during monsoon seasons.

The increasing demand for fresh water has necessitated the exploration for new sources of groundwater, particularly in hard rock terrain, where groundwater is a vital source of fresh water. A fast, cost effective and economical way of exploration is to study and analyze remote sensing data. Interpreted remote sensing data was used to select sites for carrying out surface geophysical investigations.
