A Graduated Approach in the Abolition of Waterborne Diseases in Drinking Water Using an Indicator Based Approach and Nano Based Biosensors: A Review

Abstract

The detection of pathogens continues to be a challenge in this present day despite the advancement in technology. The emergence of waterborne diseases is of great importance and their rapid detection and identification in water is of utmost importance. Water quality indicators and pathogen detection in environmental water samples is significant for maintaining safe drinking water. Traditional methods like the culture-based methods are laborious, time consuming and yield false-positive results. Hence, a lot of research has been put in developing rapid detection methods and quantifying water pathogens in water. These methods include the use of water quality indicators as early warning systems and nano material based biosensor detection methods. The review highlights “the state of the art” method for monitoring and detecting waterborne pathogens. The review summarizes the microbiological water quality indicators and biosensor based methods. These methods are time effective, sensitive, specific and therefore important in the diagnosis and prevention of waterborne diseases.

Keywords: Waterborne Diseases, Biosensor based methods, Water quality indicators , Pathogens.
