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

Abstract Because water serves as vehicles in the transmission of many pathogens‚ coliforms are commonly used as indicators to monitor the quality of water. I hypothesized that Lake Thoreau would have more fecal coliforms because it is a more stagnant environment meaning more animals can stop their and release their feces‚ and also the animals that reside there continue to reproduce‚ leaving no exit for their excretions. By using the MPN test‚ I was able to detect the coliforms from the fermentation
