Step-by-step explanation

Parameters                           Maximum prescribed concentration in  drinking water                                                                        

Iron                                         0.2 ppm

Fluroide                                  1.5 ppm

Lead                                        50 ppb

Nitrate                                     50 ppm

Hence the concentration of nitrate in a given
water sample exceeds from the upper limit as
given above.
