Unutar Parka prirode Medvednica postoje brojni izvori pitke vode. Cilj ovog istraživanja bio je odrediti je li voda iz odabranih izvora uz popularna izletišta u trenutku uzorkovanja pogodna za piće. Uzorci vode sakupljeni su 11. prosinca 2016. iz izvora Vidovec, Baćun, Bliznec, izvora na vrhu Leustekove staze i iz Kraljičinog zdenca. Određen je broj ukupnih heterotrofnih bakterija, fekalnih koliforma, crijevnih enterokoka i bakterija roda Pseudomonas te koncentracija suspendiranih čestica i pH vode. Rezultati analize upućuju da je u trenutku uzorkovanja voda iz izvora Vidovec, Baćun i Bliznec bila pogodna za piće. Voda iz izvora na vrhu Leustekove staze zbog prevelikog broja heterotrofa i voda iz Kraljičinog zdenca zbog jednog nalaza bakterije Escherichia coli u trenutku uzorkovanja nije bila pogodna za piće. Kako bi dobili potpuniju sliku o tome je li voda s istraživanih izvora pogodna za piće potrebno je provesti sustavno praćenje kvalitete vode.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\u27s 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\u27s 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
