A study on chemical analysis of drinking water from some communities in Nandyal rural areas of Kurnool district, Andhra pradesh, India

This study consisted of the determination of the trace metal ions and some physiochemical properties in drinking water samples from the neighboring villages of Nandyal region, Kurnool district, where drinking water samples are not treated before it is consumed. The purpose was to ascertain the quality of water from these sources. Samples were taken from ten sampling points and analyzed for the following parameters Fe, Cu, Mn, Zn, Al, pH,EC,NO₃-, SO₄, and F- using the procedure outline in the plain test photometer method. The data showed the variation of the investigated parameters in samples as follows: pH 5.47–7.39, conductivity (EC) 49–1168 μs/cm, turbidity 4.68–73.34JTU, F - 0.54 to 1.29mg/L.NO₃-11.19 to 39.76 mg/L, SO₄2- 41.2 to 73.0 mg/L Cu 1.25 to 2.96 mg/L. Fe 0.08–0.94mg/L, Zn 5–19 mg/L,Mn 0.004–0.016 mg/L and Al 0.07–0.18 mg/L, The concentrations of most of the investigated parameters in the drinking water samples from Nandyal region were within the permissible limits of the World Health Organization drinking water quality guidelines.
