The objective of this research is to study the Physico-chemical parameters of water by sampling Hand pump, Bore well, Vagu and Cheruvu water of 6 selected sites of Polkampally, Ghanapuram, Kodhandapuram, Mallaiahpallem, Nemalipuram, Pinnavura of Nalgonda district of Telangana, India. The variation of physical and chemical parameters such as temp, pH, TDS, SP and Co3, CaCl2, F, So4, Mg, Na, k, No3 contain were analysed for a period of one year. All parameter were within the permissible limits. From the result it was found that water of Polkampally Vagu was marginal for agriculture and other sources of water was probably safe or it can be used for domestic or irrigation purpose only. Therefore it offers as a significant value to physico-chemical water quality standards.
Physio-chemical parameters; Water quality standards
Ecosystem is known as the lifeline of earth which most significantly uses the water compound. By physical, chemical and biological characteristics we can describe better quality of water. But some correlation is possible among these parameters and the significant one would be useful to indicate quality of water [1-3]. Due to increased human population, industrialization, use of fertilizers in agriculture and man-made activity, the natural aquatic resources are causing heavy and varied pollution in the aquatic environment leading to water quality and depletion of aquatic biota. It is therefore necessary that the quality of drinking water should be checked at regular time interval because due to use of contaminated drinking water, human population suffers from a variety of water borne diseases [3-5]. It is difficult to understand the biological phenomena fully because the chemistry of water reveals much about the metabolism. The ecosystem and explain the general hydro biological relationship. The physico-chemical parameters of water and the dependence of all life process of these factors make it desirable to take as an environment. It is therefore necessary that the quality of drinking water should be checked at regular time of interval, because due to use of contaminated drinking water, human population suffers from varied of water borne diseases. It is difficult to understand the biological phenomena fully because the chemistry of water revels much about the metabolism of the ecosystem and explain the general hydro-biological relationship [6-8].
The present study involves analysis of water quality in terms of physico-chemical parameters of six sites Polkampally, Ghanapuram, Kodhandapuram, Mallaiahpallem, Nemalipuram, Pinnavura of Nalgonda district. It is located in Nalgonda district, Telangana. Water samples of these sites are basically used for domestic and agriculture purpose.
Water sample were collected in polythene bottle from Hand pump, Bore well, Open well, Vagu and Cheruvu from Polkampally, Ghanapuram, Kodhandapuram, Mallaiahpallem, Nemalipuram and Pinnavura of Nalgonda district (Table 1). Water samples were collected and brought into the laboratory for the analysis of various physical and chemical parameters—pH, Conductivity, TDS, Carbonate, Nitrate, Calcium, Magnesium, Sulphate, Chloride, Fluoride, and Sodium. All parameters were within the permissible limits (Table 2).

Table 2: Physical (pH, SP Conductivity & TDS) parameters of Nalgonda district water sample.
In present study, pH value was found between 7.29-8.35. It shows the alkalinity of water sample throughout the periods. The high value of pH is due to the deposition of sewage and agriculture waste. pH value is essential for the growth of aquatic flora [9,10].
The conductivity of water ranges from 529-3070 at 25°C. The correlation between conductivity and physio-chemical parameters were beneficial for understanding the quality of water. It can measure by controlling the conductivity of water by EC meter. The conductivity of water sample was observed by standardized with KCL solution through standard instrument [11-14].
Sodium absorption ratio
In present study the SAR ratio ranges between 1.25-5.53. SAR is an acceptability of water for agriculture purpose. SAR ratio was analysis by the concentration of total solid in the water. If the SAR ratio were higher it is less satisfactory for irrigation. High SAR ratio will damage the quality of soil. Its sodium ratio decreases the calcium and magnesium from the soil .
Total dissolves oxygen
The values of carbonate fluctuate from 0-40 mg/l and 0.00-0.80 ppm. In water sample high pH shows the presence of carbonate if the pH is reduced it shows the conversion of carbonate into bicarbonate. It can be examine with the help of titration by standard HCl using phenolphthalein as indicator.
The values of Chloride 40-560 mg/l and 1.41-15.79 ppm. It is examine by titrate the know value of sample by standardized silver nitrate solution using potassium chromate solution in water (Table 3).

The value of calcium ranges observed between 16-120 mg/l and 0.80-6.00 ppm. It was estimated by titration.
The value of magnesium observed between 5-102 mg/l and 0.40- 8.40 ppm. It was estimated by titration through EDTA standard .
Water quality is dependent on the type of the pollutant added and the nature of mineral found at particular zone of bore well. Monitoring of the water quality of ground water is done by collecting representative water samples and analysis of physico-chemical characteristics of water samples at different locations of Nalgonda district [23,24]. Estimation of water quality index through formulation of appropriate using method and evaluate the quality of different water by statistical analysis by physico-chemical properties. From the result it was found that water of Polkampally Vagu was marginal for agriculture and other sources of water was probably safe or it can be used for domestic or irrigation purpose only. Therefore it offers as a significant value to physicochemical water quality standards.
