“…Studies across different regions of Andhra Pradesh have revealed varying levels of fluoride in different hydrogeological conditions. The results revealed in this study show substantial variations in fluoride concentrations across the varying water sources which are in line with other parts of the Andhra Pradesh [19,21,22,35]. These findings hold significance not only at a local level but also within the broader regional context of water quality and public health.…”

“…The average F − content of unsafe groundwater was more than 2.5 mg/L (except 2015 because of less data points) across the mentioned years with maximum range 3.8 to 5.4 mg/L from 2014 to 2018 (excluding 2015). The existing groundwater fluoride concentration lies within the range of 0.3 to 12.9 mg/L based on reported studies [19][20][21][22][23].…”

There has been a growing concern over the occurrence of fluoride (F−) in groundwater and the impact of F− exposure on human health issues over the past decades. So, this study conducted a regional–scale assessment of the occurrence and trend of groundwater F− distribution [2014–2018] integrated with locally field–based investigations on F− exposure to a few selected families (10 households and 35 respondents) and reason behind their consumption of F− containing water (n = 18). In the local study, water samples were collected from multiple sources around the selected households by dividing them into consumptive and non–consumptive use. Results revealed that across the state of Andhra Pradesh, the occurrence of F− is more than the permissible limit in groundwater, and it has been increasing over the years (2014–2018) (average SD is 0.55), and the local study showed that the groundwater had an average of 1.5 mg/L F−, while other sourced water had an average of <1 mg/L F−. Most interestingly, nine families are consuming non–F− containing water (<0.52 mg F−/day) which is commercially available, while only one family is consuming F− containing groundwater and being exposed to >3 mg F−/day. This disparity in fluoride exposure is dependent on economic stability and health exposure policies.

Coal is a dirty fuel contaminated with F − and other elements. Several million tons of coal are burnt in Korba basin, central India to generate electricity with pouring fluorine and other elements into the environment. The water is contaminated with F − and other chemicals beyond the permissible limits. The contaminated water is consumed by the human and animals by excreting the balanced toxicants through the stool and urine. Several folds higher concentration of F − in urine (44 mg/L) and stool (266 mg/kg) samples of the cattle are observed. The prevalence of fluorosis diseases in cattle of the Korba basin is reported.

“…Nearly 80% of all the nitrogen added to the atmosphere accounts for the development of agriculture and livestock. Agricultural practices, septic tank leakage, unlined drainage and sewerage pipes, domestic sewage, leaching from indiscriminate disposal of animal waste can result in higher nitrate concentrations (Reddy et al 2013, Datta et al 1996Sunitha et al 2012a, b, c). The majority of people in this area depend for their livelihood on farming practices, the use of fertilizers for crop yields may be the main contributing factor for high nitrate concentrations.…”

Fifty groundwater samples were obtained pre and post-monsoon seasons in parts of hard rock terrain in Andhra Pradesh, South India, in order to assess the drinking water quality. PIG values of groundwater samples ranged from 0.95–1.53 and 0.83–1.28 during pre and post-monsoon seasons. PIG values are slightly higher in the pre-monsoon season when compared to the post-monsoon season. In the pre monsoon season, 96% of the groundwater samples showed insignificant pollution class (< 1), 4% of the groundwater samples are low pollution (1–1.5). 82% of the groundwater samples showed insignificant pollution status (< 1), 18% of the groundwater samples fall under the low pollution (1–1.5), is noticed in post-monsoon season, respectively. WQI values of groundwater samples ranged from 108.5–204 mg/L and 112.6–170 mg/L during pre and post-monsoon seasons; its shows that 100% are very poor for drinking purpose. Piper diagram reveals that groundwater is majorly mixed Ca2+-Mg2+-Cl−, Ca2+-Mg2+-Cl−-SO42−, Na+-K+-Cl−- SO42− type in this region. The Gibbs plot indicates that groundwater samples fall within the field of rock dominance. Through applying GIS techniques, the spatial distribution of groundwater quality analysis reveals that most of the groundwater samples do not comply drinking water quality standards and water needs to be prior treatment before consumption.
