ThesisItem Open Access QUALITY ASSESSMENT OF UNDERGROUND DRINKING WATER SOURCES OF AGRICULTURE UNIVERSITY PALAMPUR, HIMACHAL PRADESH(CSKHPKV, Palampur, 2018-07) Meenakshi; Chauhan, Ramesh C.The present investigation was carried out to assess the underground drinking water quality of Agriculture University Palampur, Himachal Pradesh. The physico-chemical characteristics such as temperature, pH, turbidity, conductivity, total solids, total suspended solids, total dissolved solids, alkalinity-P, alkalinity-M, total alkalinity, calcium, magnesium, chloride, fluoride, iron, total nitrate-nitrogen, total phosphate-phosphorous and microbiological characteristics like total coliform were estimated and recorded at four different study sites seasonally from July-2017 to June- 2018. The majority of physico-chemical characteristics showed significant relationships among themselves. The quality parameters i.e. temperature, pH, turbidity, conductivity, total solids, total suspended , total dissolved solids, total alkalinity, calcium, magnesium, chloride, fluoride, total nitrate-nitrogen, phosphate-phosphorous and microbiological characteristics like total coliform were found much below the desirable limit except for iron as per BIS. The iron concentration during study was recorded maximum (1.54 mg/L) in the summer season and minimum (1.4 mg/L) in rainy season which is beyond the permissible limit as per BIS. Although iron has got little concern as a health hazard but is still considered as a nuisance in excessive quantities. The limits of iron in waters are based on aesthetic and taste consideration rather than its physiological effects. Microbiologically also all of the water samples were found free of MPN bacteria. It can, therefore, be concluded that the underground water of university is of very good quality and suitable for drinking purposesThesisItem Open Access Combining ability and heterosis studies involving test crosses of inbred lines in maize (Zea mays L.)(CSKHPKV, Palampur, 1997) Meenakshi; Sharma, J.K.ThesisItem Open Access Studies on microbiological dynamics in an aquaculture ecosystem under mid-hill conditions of North-West Himalayas(CSKHPKV, Palampur, 2004) Meenakshi; Sharma, C.R.
