A Study of Ground Water Quality for Irrigation Purposes in SIDCUL-Rudrapur of Udham Singh Nagar District, Uttarakhand

摘要

The present study was conducted to study suitability of ground water for irrigation purposes. The water samples for the physico-chemical analysis were collected from the deep and shallow hand pumps of the 24 locations of SIDCUL (State Industrial Development Corporation Uttarakhand Limited) near Rudrapur of Udham Singh Nagar district, Uttarakhand to analyzed for Mg:Ca ratio, Percent Na, Exchangeable sodium percentage (ESP), Sodium absorption ratio (SAR) and Soluble sodium percentage (SSP). The categorization of the ground water for irrigation was studied with the help of standard criteria. The study revealed that two out of 24 water samples were found under C3 class of salinity which implied that the water from these places was highly saline. One outof 24 and two out of 24 were found unsuitable on the basis of percent sodium and under permissible category on the basis of electrical conductivity. Two out of 24 were found to have slight to moderate effect on availability of water to crops on the basis of salinity and Nine out of 24 water samples were having no toxicity effect while other sampleswere having slight to moderate effect of ion toxicity on the basis of SAR ratio.
