A water sample has been analyzed for phosphate using UVVS method at 662 nm wavelength. The molar absorptivity of the standard phosphate gives a value of 1.03 x 103 L/mol.cm and an average absorbance reading of 0.431 for the water sample. Is the water from where the sample is taken safe for human drinking?
