Water quality assessment of Majhiaon block of Garwa district in Jharkhand with special focus on fluoride analysis

Abstract

Fluoride in groundwater is known to contaminate the water sources globally. Jharkhand, one of the states in the eastern part of India, is known to have excessive fluoride content in groundwater sources. The present work involves assessment of water quality with special reference to fluoride in Majhiaon block of Garwa district in Jharkhand. Iron, nitrate and arsenic were also tested for the water samples collected from site. Eight hundred forty samples were tested for fluoride on site using colourimetry method, and one tenth of the samples were brought to laboratory for iron, nitrate, arsenic and fluoride analysis. Results show that 402 samples were having fluoride above permissible limit. Iron and nitrate were found to be beyond permissible limits in 302 and 286 water samples, respectively. More than 50% of samples collected from school had fluoride levels above permissible limits. Arsenic was well within the limits. However, few samples shown were excessive of iron and nitrate.

Groundwater hydrochemistry and consumption patterns in Chandwara community development block of Jharkhand state in India

“…As per Singh et al (2012), F − levels were < 1.0 mg l −1 in most of the samples collected from Dumka and Jamtara Districts in Jharkhand state. Some other districts also in the state have areas where groundwater F − is above the permissible level of BIS ( 2012) (Kumari and Pathak, 2014;Avishek et al 2010;Patolia and Sinha, 2017).…”

Groundwater Quality

“…The chemical analysis showed that groundwater of Kaithal district in Haryana was hard, alkaline and saline, but it was still within safe limits for domestic use (Goyal, 2010). The Over 50% of the samples contained fluoride higher than the permissible limit (Avishek et al, 2010). Up to 7.85 mg/L Fconcentrations were detected in groundwater near Nagar Parkar Town, Pakistan (Naseem et al, 2010).…”

Integrated Framework for Identification of Polluted Zones in Coastal Areas of Thiruvallur District of Tamil Nadu (India)

“…Most water quality indices rely on normalizing or standardizing, data parameter by parameter according to expected concentrations and some interpretation of 'good' versus 'bad' concentrations (Jacintha et al, 2016). Parameters are often then weighted according to their perceived importance to overall water quality and the index is calculated as the weighted average of all observations of interest (Avishek et al, 2010;Saeedi et al, 2010). The index is a numerical standardized value of evaluation on a certain matter which is in composite form.…”
