The study report is discusses about the analysis of various physicochemical
parameters of salinity, TSS, TDS, DO, BOD, turbidity, pH, temperature, alkalinity, hardness and dissolved nutrients of surface water and sediments collected from different points (5 stations) of
Karamana River were measured during March and July 2009. The highest temperature
(31.0ºC) noticed during premonsoon
period and no influence of salinity. In the monsoon
period, high DO ranges (5.4mg/L) noticed in the water of Karamana River. High BOD
observed at Thiruvallam indicated the influence of effluents in these stations. TSS 17mg/L at Manakatukadavu to 40mg/L at Thiruvallam during premonsoon
and 24mg/L at Manakatukadavu to 60 mg/L at Pallichal during monsoon. TDS in water samples increased from 56mg/L at station 1 to 28mg/L at station 5 during premonsoon and from 41mg/L at station 1 to 112mg/L at station 5 the high TDS might be due to the influence of seawater. Total alkalinity observed in the present study is well within the prescribed standards of drinking water (>1 20mg/L). High hardness 12 mg/L) noticed at Karamana near Siva temple during premonsoon
period. Total Iron concentrations is high as 1.08 to 2.52mg/L in premonsoon
and 1.51 to 2.24mg/L during monsoon recorded at station 5 might be due to the
high rate of surface runoff in waters. Total phosphate value (2.562.19mg/ kg) at Pallichal showed the deposition of nutrients during monsoon season. The distribution of heterotrophic population was highly fluctuating daring the study and the high counts (417cfu/ml to 524dfu/ml) during monsoon at Mankattukadavu and Kundamankkadavu.

    ABSTRACT: - Water is a valued natural resource for the existence of all living organisms. Indian rivers are polluted due to the discharge of untreated sewage and industrial effluents. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution of Kaushalya River in Parwanoo. The water quality was studied quarterly at two sites at upstream and downstream regions during 2011 in the months of January, April, July and October. Physico-chemical and microbiological analyzed. Also the correlation coefficients between parameters of river water samples were parameters of the samples were measured, moreover, possible sources of contamination were determined. Most of the parameters analysed for Kaushalya river were in acceptable range except COD, Alkalinity, Hardness, Total Coliform and Faecal Coliform which showed human, animal and agricultural activities as the main sources of pollution. Trace metal and pesticides levels were low suggesting low contamination of the river by industrial wastes and toxics. However due to presence of a water treatment plant in the village Kamli from where the water of Kaushalya river is supplied to different sectors of Parwanoo, the river is suitable for drinking, bathing, recreation, irrigation and industrial uses, etc. Thus the overall water quality of the study site remained within the safe limits throughout the study period. Though the river is safe, still some of the conservation and management plans are proposed to reduce the sewage and the agricultural impacts on the river.
