Phenol C6H5OH. Parts per billion.
125/10^9
= 1.25 X 10^-7 molecules of phenol
1.25 X 10^-7 molecules C6H5OH (1 mole C6H5OH/6.022 X 10^23)(94.108 grams)
= 1.95 X 10^-29 grams phenol
10^9 molecules H2O (1 mole H2O/6.022 X 10^23)(18.016 grams/1 mole H2O)
2.99 X 10^-14 grams water
1.95 X 10^-29/2.99 X 10^-14 * 100
= 6.52 X 10^-14% phenol mass in water
