—The objective of this study was the river water
quality assessment of Loimata o Apaula (LoA) watershed
catchment in Samoa. River water samples from upstream and
downstream are were collected and analyzed for heavy metals
and nitrates/phosphorus. Among various heavy metals examined
lead in upstream river water was higher than in downstream.
Similarly to cyanide and nitrate concentration were higher in
upstream than downstream with some concentration below the
permissible maximum concentration of environment quality
