Sažetak
This study shows the results of research on the chemical and microbiological quality of drinking water samples from farms in the area of northwest Croatia. A total of 120 samples of water from different farms (65 chicken broiler and laying hen farms, 45 cattle farms, and 10 swine farms) that were collected throughout 2016 and spring 2017 were analyzed. A basic microbiological analysis was performed using the following parameters: total coliforms, Escherichia coli, intestinal enterococci, colony count at 36 °C and 22 °C, Clostridium perfringens and Pseudomonas aeruginosa. A physicochemical analysis was conducted using the following parameters: taste, odor, color, pH, hardness, free chlorine, chlorides, sulfates, nitrites, nitrates, sodium, ammonium, potassium, magnesium, calcium, iron and consumption of KMnO4. Of the 120 analyzed samples, 40.0% were microbiologically unsuitable and 37.5% were chemically unsuitable under Croatian water quality regulations (Official Gazette (OG) 125/2013, 141/2013, 128/2015). The analysis of the water supply on farms in northwest Croatia reveals a high percentage (58.3%) of chemically and/or microbiologically unsuitable water samples. Alloftheunsuitablesamplescamefromwells, and it may be concluded that it is necessary to conduct more water quality controls, appropriate surveillance and disinfection on a regular basis.
