The present invention includes a liquid sanitization device including one or more light emitting diodes (LED) that emit electro-magnetic radiation primarily at two or more distinct wavelengths. These wavelengths should be less than about 300 nm, preferably between about 210 to about 300 nm. The radiation from the light emitting diode or diodes kills or interacts with the DNA or RNA of pathogenic organisms in the liquid to prevent the organisms from reproducing or harming desirable organisms.
