Appraisal of seasonal variations in water quality of river Cauvery using multivariate analysis

Water Science, 2021

The present study determines the water quality (WQ) of river Cauvery and its distributaries in Tiruchirappalli district, Tamil Nadu state, India, through WQ parameters and also using multivariate analysis. The water samples were collected by grab sampling method during the four seasons, namely, winter, summer, southwest, and northeast monsoons of the year 2014-15. The study reveals that total dissolved solids, turbidity, total alkalinity, total hardness, biological oxygen demand, chemical oxygen demand, and total coliform results of river Cauvery and the distributaries exceeded the drinking water standards, which are mainly in summer. Also, the outcomes of principal component analysis and cluster analysis confirmed the high pollution loads in the water samples. It could be caused by the sewage discharges from residential and commercial areas. Moreover, solid wastes dumping and all sorts of cleaning activities were found at all stations. The present study concluded that the water from river Cauvery and its distributaries are not potable directly. With awareness creation and water treatment methods among the consumers, the river system can be conserved for proper usages.

Seasonalvariations in Physico-Chemicalparameters of Ground- Water in Sambadistrict (J&K), India

2016

Water quality is an important criterion for determining the suitability of water for human consumption and for various other uses. In this work various physico-chemical parameters viz. pH, turbidity, total dissolved solids (TDS), electrical conductivity (EC), total alkalinity (TA), total hardness (TH), calcium (Ca2+), magnesium (Mg2+), chloride (Cl''), sodium (Na+), potassium(K+), sulphate (SO/,'), phosphate (PO/,') and fluoride (F-) of samples of groundwater sources of the study area were investigated from April 2011 to March 2012. The results obtained were compared with WHO (1997) and BIS (2012) standards set for drinking water quality. The studied groundwater samples were found suitable for drinking. INTRODUCTION About 71 % of the area of earth is covered with water. Groundwater which is available to us in the form ofbore wells, dug wells and hand pumps is considered the safest and unpolluted source ofdrinking water. Majority ofIndian population depend on groundwa...

ANALYSIS OF WATER QUALITY (CHANGES IN PHYSICO-CHEMICAL PARAMETERS)

International Journal of Current Research, 2016

The present study dealt with assessment of the physico coefficient of vedadri reservoir, Krishna district, AP, India. The physico correlation coefficient were studied and analyzed during ja in water samples of Vedadri in different seasons were observed. The results stated that there was significant seasonal changes in some physico in normal limit showed high significant positive and negative relationship (p<0.01) and also show significant positive and negative relationship (p<0.05).
