Analysis of Water Quality Using Physico-chemical Parameters of Mula-Mutha River, Pune Maharashtra

Abstract

We want to present an extensive work on physico chemical parameters of water samples of Mula river at Pune (Maharashtra). Water samples under investigations were collected from Khadkwasla dam to Sangam Bridge during pre monsoon (April May2016) monsoon (July-August2016) and post monsoon (October-November2016) seasons. The observed values of different physico parameters like pH, DO, BOD, COD, Chloride, Nitrate, Sulphate, Calcium, Magnesium and Hardness, etc. of samples were compared with standard values recommended by world health organization (WHO). The Mula-Mutha River water in Pune had deteriorated in quality. Its biological oxygen demand, an indicator of organic pollution, has risen to over 30 mg/l, more than ten times t permissible limits for bathing. Municipal Corporation is currently supplying water sufficient for the projected population. More water means more sewage, beyond the quantum its sewage treatment plants can treat. As a result there is greater pollution loads discharged in to the Mula-Mutha, two rivers that confluence within city limits and serve to flush away Pune's excreta. All the physico-chemical parameters for pre monsoon, monsoon and post monsoon seasons are within the highest desirable or maximum permissible limit set by WHO except some of the parameters like DO, BOD,COD, chloride, calcium, magnesium and hardness.

The Relationship between water quality and Macrophyte biomass of Kongba River, Manipur, India

“…The present observation finds support with the work of Akumtoshi et al, 2020 in Doyang River, Nagaland. The raised values of D.O during winter season in Site I were due to high photosynthetic rate by phytoplankton during which more CO 2 is utilised and O 2 is released (Jadhav and Jadhav, 2018). The DO level in our study site was found to be higher than the acceptable limits of 5 mg -1 (BIS, 2003).…”

Potential of Vermicompost for Sustainable Crop Production and Soil Health Improvement in Different Cropping Systems

“…Vermicompost application 2.5 t ha -1 increased gram and straw yield of rice significantly and saved up to 50% of recommended NPK fertilizer rates in upland rice (Angadi and Radder, 1996). Earthworms' cast (vermicompost) found to be a better source for enhanced plant growth, dry matter production, productivity and also indicated the possibility of substituting 50 kg N ha -1 from the recommended dose of N (Jadhav et al, 1997)). Thus, vermicompost usage reduced dependence on costly fertilizer input and enhanced net returns from rice produce (Nagaranjan, 1997).…”

Analysis of Physiochemical Parameters and Heavy Metal Pollution in Chenab River and its Tributaries, Jammu &Kashmir

“…Water is the most vital resource required for survival of life forms on earth Mishra et al 2020;Jadhav et al 2020). The freshwater bodies play an integral role in ful lling water demands in industrial, domestic and farming purposes Cahyanto et al 2019;Nguyen etal.2019).…”
