water is one of the primary resources to sustain human life. the quality of good water and air are important factors to protect human health and the environment. the impact of container material on stored water quality is investigated in this study. the objective of this research is to compare the performance of a polyethylene (plastic) container to that of a bioplastic container over a period of 32 days. water quality parameters analyzed were temperature, acidity (ph), turbidity and dissolved oxygen (do). both container types met the water quality requirements for safe drinking water, but the bioplastic container performed better over polyethylene. bioplastic materials have the added sustainable benefit of being made from natural components that result in less harm to the environment both in production and degradability.
