ThesisItem Open Access ASSESSMENT OF WATER QUALITY AND ITS RELATIONSHIP WITH HUMAN HEALTH IN SOLAN DISTRICT OF HIMACHAL PRADESH(UHF,NAUNI, 2019-05) SINGH, AJAY KUMAR; BHARDWAJ, S KABSTRACT The present investigation entitled “Assessment of water quality and its relationship with human health in Solan district of Himachal Pradesh” was conducted in the year 2017 and 2018 to determine water sanitation and hygiene, diarrhoeal disease, water quality status and its relationship with human health. The study indicated streams as the major water source used for drinking purpose. The practices like washing of farm produce, grazing of animals, dumping of wastes, washing of clothes and open defecation around the water sources have been noticed as the cause of contamination. Solan district has been observed to be prone to the incidence of diarrhoeal disease as evinced by 1353-23791 cases annually. Consequently, the water quality assessment was hypothesized. To conduct the study, the district was divided into seven very high and one low disease burden regions. To assess the seasonal variation the two seasons namely monsoon and post monsoon were selected. Accordingly physical and chemical water quality parameters were assessed by arranging field study in Randomized Block Design (factorial) by taking 16 treatments which were replicated ten times. Out of these, the first five most preferably used water sources from each region, were further selected for the microbiological assessment of the water. The study pointed out that the physical-chemical parameters of the drinking water sources of disease burden regions were within the permissible limits prescribed by BIS and ICMR except for turbidity, BOD and trace elements trace elements like Pb, Hg and Cr. The turbidity, BOD and the contents of Pb, Hg and Cr were in the range of 2.20 - 6.60 mg l-1, 11.00 - 22.52 mg l-1, 0.15 - 0.43 mg l-1), 0.002 to 0.029 mg l-1 and 0.04 - 0.09 mg l-1 respectively. The water quality index computed by considering nine quality parameters indicated that majority of the hand pumps i.e. 62.5% are having good water quality followed by 25% of the bore wells and 35.29% protected springs. The disease burden regions of Solan were having total coliforms in the range of 5-30 MPN per 100 ml water indicating the presence of enteric pathogens. The genus Raoutella was identified as the main fecal indicator organism from contaminated samples. The deterioration of water quality was more in the monsoon season and in the regions having the presence of industries. The positive correlation of contaminated water with diarrhoea during monsoon (r = 0.88) and post monsoon season (r = 0.74) indicated towards unsafe environmental conditions which need to be looked into for maintaining water sanitation and hygiene in the region for sustainable human health management.ThesisItem Open Access STUDY OF THE EFFECT OF FOLIAR SPRAY OF ZINC AND BORON UNDER VARIOUS LEVLES OF NITROGEN AND PHOSPHORUS ON THE GROWTH AND LEAF CONTENTS OF ONE YEAR OLD NAGPUR SANTARA CITRUS RETICULATA(JNKVV,JABALPUR, 1968) SINGH, AJAY KUMAR; JYOTISHI, R.P.
