In the rural areas of Uttarakhand, the surface water, mainly springs and streams, is vital resource of potable water for domestic consumption. The population residing in Uttarakhand relies on surface water for drinking, agriculture, hydropower, and tourism. Springs, locally known as dhara or naula, are the primary water source for many villages, especially in the hilly regions. However, drying springs and declining water quality, particularly during the summer, have caused water shortages, forcing local communities to rely on alternative or more distant sources. The springs are basically groundwater that emerges from an opening and flows on the surface. The environmental factors impacting the water quality include lithostratigraphy, rainfall pattern, and degree of weathering of rocks. Moreover, the growing urbanization and industrialization in the region have put stress on the existing water resources apart from deteriorating the quality of water in the region. The present study focuses on the springs in the Nainital region of Uttarakhand. The water quality of springs has been assessed in the pre-monsoon and post-monsoon periods to ascertain the water quality in the region. The water quality index has been calculated, and it was ascertained that the springs fall in the poor to very poor range. Hence, the water must be treated before consumption.

摘要

In the rural areas of Uttarakhand, the surface water, mainly springs and streams, is vital resource of potable water for domestic consumption. The population residing in Uttarakhand relies on surface water for drinking, agriculture, hydropower, and tourism. Springs, locally known as dhara or naula, are the primary water source for many villages, especially in the hilly regions. However, drying springs and declining water quality, particularly during the summer, have caused water shortages, forcing local communities to rely on alternative or more distant sources. The springs are basically groundwater that emerges from an opening and flows on the surface. The environmental factors impacting the water quality include lithostratigraphy, rainfall pattern, and degree of weathering of rocks. Moreover, the growing urbanization and industrialization in the region have put stress on the existing water resources apart from deteriorating the quality of water in the region. The present study focuses on the springs in the Nainital region of Uttarakhand. The water quality of springs has been assessed in the pre-monsoon and post-monsoon periods to ascertain the water quality in the region. The water quality index has been calculated, and it was ascertained that the springs fall in the poor to very poor range. Hence, the water must be treated before consumption.
