The aim of the study was to investigate and assess the quality of water, obtained from own well source at a poultry farm - with capacity 13 350 hens and turkeys, situated in rural area in South Bulgaria, on the basis of organoleptic - smell, color, visibility, taste, physical - temperature and chemical - pH, permanganate oxidation, hardness, chlorides, ammonia, nitrates, nitrites indices. It was found that the quality of water corresponded to the norms concerning the organoleptic - smell – 0 ball, norm up to 2 ball; color - 5°, norm up to 15°; visibility - over 60 cm thickness of water plast, norm at least 30 cm; taste - no flavor, norm no flavor, physical - temperature – 13.5-16.8 oC, norm 6-16 oC and chemical - pH 6.80÷7.15, norm 6.5-9.5; oxidizability 0.24÷0.72 mg O /l, norm up to 5.0 2 mg O /l; hardness 6.49÷7.55 mg Σqv/l, norm up to 12.0 mg Σqv/l; chlorides 162.0÷197.0 mg/l, norm up to 250.0 mg/l and nitrites 0.0÷0.021 mg/l, norm up to 2 0.5 mg/l indices. The most significant deviation from quality standards were observed regarding the concentration of ammonia - 0.01÷0.6, norm up to 0.5 mg/l and nitrates - 58.0÷110.0 mg/l, norm up to 50.0 mg/l.
