Article Synopsis
- Groundwater quality is critical for health and agriculture but is often overlooked, leading to contamination, particularly in Kerala, India, where 62% of the population depends on it from millions of open wells.
- This study uses machine learning techniques like random forest and others to analyze groundwater quality across Kerala, recognizing varying quality levels and validating them with spatial diagrams.
- The findings reveal that 7.4% of the state has poor-quality groundwater, endangering around 0.59 million people, highlighting the need for sustainable groundwater management and addressing public health risks.
Article Synopsis
- Nitrate-contaminated groundwater poses health risks, especially for children, and a study in Kerala, India assessed nitrate levels and potential health impacts in 2010 and 2018.
- The study analyzed data from 324 wells, revealing increasing nitrate concentrations over time and significant spatial variability, with the highest levels remaining consistent across the years.
- Health risk assessments indicated a notable rise in non-carcinogenic risks for both females and children from 2010 to 2018, highlighting the urgent need for improved water quality management in affected areas.
Evaluation of aquifer potential is essential, as the potable water demand has increased globally over the last few decades. The present study delineated different zones of groundwater potential and groundwater quality of the Kallada River basin (KRB) in southern India, using geo-environmental and hydrogeochemical parameters, respectively. Geo-environmental variables considered include relative relief, land use/land cover, drainage density, slope angle, geomorphology, and geology, while hydrogeochemical parameters include pH, electrical conductivity (EC), Cl, Fe, and Al concentrations.
