DISTRIBUTION AND OCCURRENCE OF CHEMICAL CONTAMINANTS IN THE SELECTED DRINKING WATER SUPPLY IN SAMOA

This study provides baseline water quality information on the distribution and occurrence of possible chemical pollutants in a Samoan drinking water source. Nitrate, chlorides, fluorides, lead, and copper levels were measured in water samples. Lead concentrations ranged from 0.24 mg/L to 0.29 mg/L, chloride concentrations from 10 mg/L to 15 mg/L, fluoride concentrations from 0.30 mg/L to 0.59 mg/L, nitrate concentrations from 1.10 mg/L to 1.90 mg/L, and nitrate concentrations from 0.19 mg/L to 0.39 mg/L. (copper). Except for lead, all quantities were below the permitted maximum concentration set by the World Health Organization (WHO).
