Abstract

The present study was carried out at Rispana River milli watershed located in Uttarakhand state.Rispana is a one of the important river in Dehradun city. The River is situated between latitude 30° 29' 15" Nand longitude to 78° 06' 98" E used in Toposheets Nos. 53-J3,53-J4 used map which provides information all topographical features. Rispana River flows starting from Mussoorie and passing through Dehradun. It is three stream order river basin.Total catchment area and Drainage length of Rispana river basin is 58.09 km2 and 130.19 km with elevations ranging from 2249 to 565 m. Its Rispana river basin main stream top to bottom total length is 12.547 km. The study area I 2different location selectedto collect the surface water sampling and 12 different location are divided 4 River sampling site.Total 180 surface water sampling from 12 different location where collected. Analysis of water quality parameters i.e physical-chemical, microbiological, major element and heavy metales was carried out and compared with BIS standard 2012. According to BIS STANDARD IS 10500: 2012 find the water quality Acceptable limit and Permissible limit. To identify use of water either Drinking purpose or not.12 location sample were also collected from divided 4 River sites. To identification different location waste water source are contaminated to main River, I sites are — (Landour Bazar, WHS Pump House, WHS Landour Bazar and WHS Rispana) Urbanization of the area to discharge of house hold waste water into the River. II sites are — (Mossy FalI,Jharipani FaIl,Shikhar Fall and Rajpur Canal Diversion) it's a fall (water body) and downstream side of first sites. III sites (Rispana River oppLuxuriaes Farm) of Rispana River slums area unauthorized colonies. IV sites-(Rispana Tail, Rispana up-Stream STP and Rispana STP) end point of river basin and it's a house hold, dairy and sewage treatment plants, solid-liquid waste are dumped in the River. The water quality is alkaline in nature, average pH is 7.1. The presence of microbiological parameter like E-coli, the maximum is 2419.610.0 MPN/100 ml and minimum is 6751425.7 MPN/100 ml. Total coliform present maximum is 2419.610.0 MPN/100 ml and minimum is 16111.5 MPN/100 ml. An average concentration of microbiological parameter is 2419.610.0 MPN/100 ml of water.The major element like cation and anion are in higher concentrations in II, III and IV site. In some locations, maximum heavy metal concentrations of iron is 3.011.7 mg/l and minimum is 0.1+0.0 mg/l, manganese maximum is 0.9+0.2 mg/1 and minimum is 0.110.0 mg/l, silica maximum is11.5±1.5 mg/1 and minimum is 3.9+0.3 mg/1, lead maximum is 0.0210.02 mg/l and minimum is0.01+0.01 mg/l, cadmium maximum is 0.00310.001 mg/1 and minimum is 0.00110.001 mg/i. In all location, higher concentration of arsenic was found to be maximum 0.00610.003 mg/l and minimum 0.001+0.001 mg/l. The presence of Aluminum maximum is 16.310.0 mg/1 and minimum is 0.110.01 mg/I.The study is find out River water harmful to drinking purpose of human health.
