Assessment on the impact of mining and industrial activities in groundwater quality in Chandrapur, Maharashtra through remote sensing and GIS applications

This study evaluated the quality of groundwater in Chandrapur
Taluka, Maharashtra, using geospatial techniques and data from
2014 and 2018. The study assessed various water quality parameters
such as chloride, fluoride, pH, residual sodium carbonate (RSC) and
sodium adsorption ratio (SAR). The findings showed that chloride
concentrations were mostly within acceptable limits, but there
was a slight increase in areas near mining and industrial sites,
which was statistically significant (p < 0.05). Fluoride levels were
generally within permissible bounds, but there was a noticeable
increase near industrial areas in 2018 compared to 2014, which
was statistically significant (p < 0.05) and raised environmental
concerns. Variations in pH values were also observed, which could
impact aquatic ecosystems, with a decrease noted from 2014 to 2018.
RSC levels were higher near mining and industrial zones in 2018,
exceeding recommended limits, indicating a potential threat to
water quality. SAR levels in 2018 were higher, potentially impacting
agriculture, but still within acceptable limits. Sulphate levels showed
a reduction from 2014 to 2018. These comprehensive findings
highlight the specific impacts of mining and industrial activities on
groundwater quality and raise broader scientific questions. They can
be used to develop evidence-based policies for effective mitigation
measures and engage a wider readership.
