- W3013079641 abstract "Microbial water contamination is a serious issue facing developing countries, especially Lebanon. It causes dangerous health risks and diseases such as Cholera. Currently, no real time test is available that can give immediate results about water microbial contamination, but without the need for reagents or high maintenance components. We worked on a new idea that can help in developing such a test to be used for the design of a real time water contamination alert device. The hypothesis we aimed to validate was that light absorbance in bacteria contaminated water sample differs before and after heating. Samples of distilled water were contaminated with cultured E. coli. Light absorbance of wavelength ranging from 205 to 600 nm was measured, using a spectrophotometer, before and after heating to 80 °C. The most promising results showed an average of approximately 15% difference in absorbance (using 550 nm wavelength). These promising results can be used to develop a fully automated device to be put near water springs in order to detect the real-time presence of E. coli as an indicator of biological contamination. A specialized circuit can be designed to control an automated testing device that samples the water and tests it. Contamination test results can be sent via network communication to a remote sensing center for early disaster warning." @default.
