Although the quality of upstream river water is generally good‚ the downstream sections of major rivers reveal poor water quality‚ and most of the lakes and canals in urban areas have become sewage sinks.

Page 2 Abstract Moringa seeds are known to contain an antimicrobial substance‚ which gets rid of microorganisms that suppresses growth. This investigatory project aims to prove that Moringa seeds can be used to purify contaminated water. The benefits of this investigatory project is that the purified water may be used in our everyday lives‚ may help in the preservation of water‚ fewer expenses would occur and adds knowledge towards the purification of water. In this experiment‚ Moringa seeds‚ a
