“…In parallel, its moderately high level of occurrence throughout the study area indicates the subsistence of newly rejuvenated groundwater. The ionic dominance trend is similar to that of leachable ions from soils, implying that minerals in the aquifer system have a pedogenic origin (Mohan & Krishnakumar, 2021). The concentration of CO 3 2− ranged from 3.22 to 16.82 (avg.…”

The quality concern of groundwater owing to human activities is mounting at a shocking rate in many of the river basins in Southern India. A study was carried out in this work to determine the quality of groundwater in the Achenkovil River Basin (ARB) in the Southern Western Ghats region of Kerala, India. A total of 25 dug well water samples were collected from the vicinity of aggregate quarries during the pre and post monsoon seasons of 2020–2021. The water quality index has been applied to categorize the water quality, namely, excellent, good, poor, etc. to infer the quality of water to the people and policy makers in the concerned area. The WQI results showed that 12% of the water samples in good and 28% depict in very poor category. The Hill‐Piper Trilinear diagram reveals that the groundwater of the study area falls under Ca2+/Mg2+, and HCO3− and SO42−, Cl−, Mg2+ types. The hydro‐chemistry of the rock‐dominant water type of the quarrying area is inhibited by geogenic‐processes along with the percolation of prevailing quarry leachate and infiltration into the nearby wells. The correlation matrix has been created and analyzed to observe their significant impetus on the assessment of groundwater quality. The overall quality of groundwater systems in the quarrying area, according to the various indices, is not fit for domestic consumption without mandatory quality treatment, but is suitable for irrigation.

Objective: To monitor and provide the first-hand information on the groundwater quality by assessing spatio-temporal variations of physicochemical characteristics and heavy metals in Aizawl, Mizoram, an Indo Burma biodiversity hotspot region. Methods: Physico-chemical characteristics of groundwater were analyzed through standard methodology following American Public Health Association (APHA) while heavy metals were analyzed using Atomic Absorption Spectrophotometer (AAS). Findings: Results revealed that several physico-chemical characteristics were observed within the range of regulatory or prescribed limits, except PO 4 3and N-NH 3 . To this end, the ranges of physico-chemical characteristics such as Total Alkalinity ((TA) 9.25 -250.9 mg/L), Total Hardness ((TH)11-242.5 mg/L), Calcium (2.2-71 mg/L), Phosphate ((PO 4 3-) 0-0.63 mg/L), Ammonia ((N-NH 3 )0.056-1.816 mg/L), Nitrate ((N-NO 2 ) 0.003-0.88 mg/L), and heavy metals, specifically Zinc ((Zn)0.2.196 mg/L) and Iron ((Fe)0-1.162 mg/L) were recorded. The present study provides first-hand information on physico-chemical characteristics, especially heavy metals in groundwater sample of Aizawl which is an integral landscape of Indo Burma biodiversity hotspot. Novelty: Groundwater pollution can be maintained in Aizawl through regular monitoring and application of green chemicals as well as phytoremediation technology to sustain the potable water quality for human well-being/-health.

“…Groundwater characterization, specifically in parts of semi‐arid and arid climate, has been done by many researchers globally (Adimalla & Venkatayogi, 2018; Keesari et al., 2014; Panahi et al., 2021; Wang et al., 2021) that shed light on the impact of intense agricultural practices and excessive groundwater withdrawal. The groundwater characteristics are usually assessed through hydro‐geochemical investigation, statistical analyses, and application of various tools like water quality indices (Mohan & Krishnakumar, 2021b; Rezaei et al., 2020). Since a change in the natural composition may affect the drinking/irrigation water quality, their estimation is crucial (Dass et al., 2001; Resmi et al., 2021).…”

Water quality index (WQI) models are generally used in hydrochemical studies to simplify complex data into single values to reflect the overall quality. In this study, deep groundwater quality in the Chittur and Palakkad Taluks of the Bharathapuzha river basin of Kerala, India, was assessed by employing the WQI method developed by the Canadian Council of Ministers of the Environment (CCME). The assessment of overall water quality is indispensable due to the specific characteristics of the study area, such as geography, climate, over‐drafting, and prevalent agricultural practices. Forty representative samples were collected from the study area for monsoon (MON) and pre‐monsoon (PRM) seasons. The results showed a general increase of contents from MON to PRM. The major cations were spread in the order Ca2+>Na+>Mg2+>K+ and the anions HCO3−>Cl−>CO32− based on their relative abundance. Among various parameters analysed, alkalinity and bicarbonate levels during MON were comparatively high, which is indicative of carbonate weathering, and 90% of the samples failed to meet the World Health Organization (WHO, 2017)/Bureau of Indian Standards (BIS, 2012) drinking water guidelines. The CCME WQI analysis revealed that nearly 50% of the samples during each season represented good and excellent categories. The samples in the poor category comprised 10% in MON and 15% in PRM. The overall WQI exhibited 15% of poor category samples as well. The spatial depiction of CCME WQI classes helped to expose zones of degraded quality in the centre to eastward parts. The spatial and temporal variations of CCME WQI classes and different physicochemical attributes indicated the influence of common factors attributing to the deep groundwater quality. The study also revealed inland salinity at Kolluparamba and Peruvamba stations, where agricultural activities were rampant with poor surface water irrigation.
