Natural organic matter (NOM) is known to be present in all natural water systems. Due to the different characteristics of surface and ground waters, the photocatalytic degradation efficiency of NOMdepends on several inhibiting and enhancing factors. The presence of hardness causing divalent cations (Ca 2+ , Mg 2+ , Fe 2+ /Fe 3+ ) as well as the accompanying common anions (e.g. Cl - , NO 3  -  ,SO 4  2-  and HCO 3  - /CO 3  2- ) have considerable effects on the degradation kinetics as expressed by DOC (dissolved organic carbon) and UV 254  (UV absorbance at 254 nm). Ternary systems formed through cation bridging of NOM displayed different adsorptive properties onto TiO 2  revealing an enhancement in removal rates. Presence of common anions as Cl - , NO 3  -  and SO 4  2-  exerted significant effects compared to the inhibitory effects due to the presence of pH dependent HCO 3  - /CO 3  2-  system. Carbonate species strictly altered the degradation efficiency possibly through the direct and competitive reactions with hydroxyl radicals. Comparative evaluations of the respective outcomes of the source dependent water quality parameters are discussed.
