Abstract:
Analysis of water quality monitoring technique based on fluorescence and UV LED is discussed. Exposing water sample to ultraviolet light induce fluorescence for detecting human faecal contaminants. Fluorometry identifies
human faecal contamination in open water  bodies. Existing systems make use of manual methods and incandescent filament based
sources combined with narrow-band interference filters. Such systems suffer from problems of stability, bulk, cost and
degradation with time. This paper review some techniques used for monitoring bacterial contaminants in water and also
looked at the feasibility of developing a UV LED fluorescence based device capable of detecting organic contaminants in
water.
