Abstract
Abstract: Different Physico-chemical parameters of Kanekal tank water, Kanekal were estimated from October 2012 to September 2014 to assess its quality. The different parameters like Temperature, pH, TDS, conductivity, salinity, dissolved oxygen, turbidity, alkalinity, free carbon dioxide, chloride, total hardness, calcium, magnesium, phosphates, sulphates, silicates, nitrites, nitrates, BOD and COD were carried out by standard methods. These parameters showed either positive or negative correlation between each other. The analysis revels these parameters are interrelated with each other. From the data it can be said that water of this tank is partially contaminated with human faeces, domestic sewage etc. Hence it is not good quality for culture of fish as well as drinking for animals.Keywords –Kanekal Tank, water quality, Physico-chemical parameters, BOD, COD
Highlights
One of the most vital parts of ecosystems is lakes
Bodies lower manair reservoir of Karimnagar district (Thirupathaiah et al, 2012), some selected freshwater fish ponds in Warangal area (Sandhya and Benarjee, 2016) investigation from our laboratory have shown that Singanamala tank and Dharmavaram tank in district of Anantapuramu have been affected and to the extent that water quality has deteriorated for human beings (Venkataramanaiah et al, 2017)
Temperature showed significant positive correlation with turbidity,total dissolved solids (TDS), carbon dioxide, chlorides, silicates, and sulfates and negative correlation with conductivity, total hardness, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), salinity, alkalinity, calcium, magnesium, phosphates, nitrates, and nitrites [Tables 1 and 2].The temperature of water bodies varies with seasons
Summary
One of the most vital parts of ecosystems is lakes. It provides important habitat and food resources to the diverse aquatic life (Kini et al, 2016). This is an important freshwater tank in Anantapuramu district It is a perennial tank into which water flow from Tungabhadra dam. This tank is used for culture of fish and this water is used for irrigation of different crops of this area. Bodies lower manair reservoir of Karimnagar district (Thirupathaiah et al, 2012), some selected freshwater fish ponds in Warangal area (Sandhya and Benarjee, 2016) investigation from our laboratory have shown that Singanamala tank and Dharmavaram tank in district of Anantapuramu have been affected and to the extent that water quality has deteriorated for human beings (Venkataramanaiah et al, 2017). In view of the above, the present study revels with the assessment of physicochemical characteristics of freshwater tank situated at Kanekal,Anantapuramu district
