Sažetak
There are numerous freshwater springs within the Nature Park Medvednica. The purpose of this investigation was to determine whether water from selected springs close to popular visitor spots is suitable for drinking at the sampling time. Water samples were collected on 11 December 2016 from the springs Vidovec, Baćun, Bliznec, the spring at the top of the Leustek trail and from the Queen's Well. The number of total heterotrophic bacteria, faecal coliforms, intestinal enterococci and bacteria of the genus Pseudomonas as well as the concentrations of suspended solids and pH of water were determined. The analysis results indicate that water from the springs Vidovec, Baćun and Bliznec was suitable for drinking at the sampling time, whereas water from the spring at the top of the Leustek trail (due to excessive heterotrophic bacteria numbers) and water from the Queen's Well (due to Escherichia coli found in one sample) were unsuitable for drinking at the sampling time. In order to gain a more comprehensive insight regarding the suitability for drinking of water from the investigated springs, a systemic monitoring of water quality should be performed.
