Abstract

In one aspect, an anti-fouling system is described for use with a water quality monitoring sensor that includes a housing with an interior cavity sized for housing a monitoring sensor. The interior cavity also includes multiple ultraviolet light sources disposed within the interior cavity that are able to reduce biota within the interior cavity. in a particular embodiment, the ultraviolet light source are ultravioleta LEDs.
