Physicochemical quality monitoring of groundwater for drinking purposes in rural Ujjain, Central India: findings of a 2-year longitudinal study

Rampant use of groundwater for drinking purposes in several parts of the world has raised the concern over its quality. Owing to increasing population, overuse, and pollution of surface water sources, the use of groundwater has increased to considerable extent. Despite this, little attention is paid towards the monitoring of groundwater resources to assess their suitability for drinking purposes. To assess the groundwater quality in rural areas of Ujjain District of Madhya Pradesh, India, in order to check its suitability for drinking purpose, water quality analysis was done at seven time points during the two study years in six villages of Ujjain District, Central India. A total of 868 groundwater samples from 124 households were collected, and standard analytical methods were employed for analysis. Overall groundwater quality of the area is good and qualified for drinking. However, occurrence of high amount of dissolved solids (> 800 mg/L) and hardness (> 400 mg/L) is the issue of concern, as long-term use of such water might result in variety of health ailments, such as kidney stones and atopic dermatitis in children. Regular monitoring and long-term surveillance of drinking water sources are necessary to keep track of the changes occurring in the system.

Automated summary

Groundwater is widely used for drinking purposes, and concerns should be raised about high levels of dissolved solids and hardness. Regular monitoring is necessary to prevent long-term health issues.
