Abstract: The aim of this paper was to study and assess the quality of water obtained from own drilled wells in cattle and sheep farms, situated in an area with strong anthropogenic impact, as a natural resource and as a resource for the watering of animals, on basic organoleptic, physico-chemical and microbiological in54 СЕЛСКОСТОПАНСКА АКАДЕМИЯ●ЖИВОТНОВЪДНИ НАУКИ, LII, 1/2015 dices. It was found that the quality of water: a) as a natural resource, is defined in “good” quality in terms of the studied physico-chemical parameters: pH, conductivity, total hardness, Ca, Mg, oxidizability, NH4+, NO2-, NO3-, SO42-, PO43-, Cl-, Mn, Fe, Zn, Pb and Cd; b) meets the stipulated norms for the watering of livestock on all organoleptic (taste, smell, transparency, color) and on part of the physico-chemical (pH, conductivity, total hardness, Ca, Mg, Mn, SO4
2-, Cl-, Mn, Fe , Zn, Pb and Cd), and sanitary-hygiene (total number of microorganisms in water of well in cattle farm) indicators; c) does not match the quality standard for water for drinking purposes on content of NH4 + and PO4
3- in water of well at cattle farm; on content of NH4+, NO2-, NO3-, PO43- and total number of microorganisms in water of well at sheep farm; on values of number of coliforms in the water of wells at two farms; d) assessed on simultaneously presence of nitrates and nitrites in water, satisfies regulatory requirements (C≤1 mg/l) for water of well at cattle farms throughout the studied period, and for water of well at sheep farm - in 3 of the 5 months of the experimental period.
