The nitrates content in waters for human consumption cannot exceed 10ppm 5m/v). Can be authorised for drinking a water containing 0.015 g of nitrates per litre?

My calculation shows xxx ppm. Hence not authorized unless you bend the rules a bit.

My calculation:
0.015g=0.015*1000=15mg
therefor 15mg/l=15ppm
so the water can not be authorised but don't know if am right with the solution
