This slide presentation outlines a joint research effort between the University of Alberta and PWN to study the ultraviolet (UV) inactivation of protozoa, viruses and bacterial spores. Topics covered include: UV disinfection collimated beam and small scale pilot experiments; UV inactivation of micro-organisms with 120 mJ/cm<sup>2</sup>,PWN pilot plant experiments; in vivo reactivation of G. murisafter medium pressure UV; surface water treatment based on breakpoint chlorination and GAC filtration; emerging organic contaminants; atrazine degradation and bromate formation in synthetic water; NDMA degradation by UV photolysis; relative degradation by UV photolysis and UV/H<sub>2</sub>O<sub>2</sub> oxidation in pretreated IJssel lake water; bromacil and atrazine degradation by UV photolysis, UV pilot plant experiments; bromacil degradation by UV/H<sub>2</sub>O<sub>2</sub> treatmentcombined effect UV photolysis and hydroxyl radical oxidation; atrazine degradation by UV/H<sub>2</sub>O<sub>2</sub> treatment combined effect UV photolysis and hydroxyl radical oxidation; UV and H<sub>2</sub>O<sub>2</sub> dose required for 80% atrazine destruction,collimated beam experiments; atrazine degradation by UV/H<sub>2</sub>O<sub>2</sub> treatment pilot plant experiments; emerging organic contaminants; microcystine degradation by UV photolysis andUV/H<sub>2</sub>O<sub>2</sub> oxidation; pharmaceutical degradation by UV/H<sub>2</sub>O<sub>2</sub> oxidation UV dose 600 mJ/cm<sup>2</sup>, H<sub>2</sub>O<sub>2</sub> dose 6 g/m<sup>3</sup>; and, conclusions on UV/H<sub>2</sub>O<sub>2</sub> treatmentfor organic contaminant control and UV disinfection and UV/H<sub>2</sub>O<sub>2</sub> treatment.
