Microbiological quality of spring water in the Nature park "Žumberak-Samoborsko gorje"

Rapidne promjene u kvaliteti vode u krškim izvorima tijekom brzog prihranjivanja tj. dotjecanja mikrobiološki zagađenom vodom je vaţna briga opskrbljivaĉima i korisnicima pitke vode. Svrha rada bila je ispitati udovoljavaju li vode iz pet odabranih izvora na području Parka prirode „Žumberak - Samoborsko gorje“ mikrobiološkim standardima prema Pravilniku o zdravstvenoj ispravnosti vode za piće (NN 47/08) te procijeniti stanje izvora in situ mjerenjem osnovnih fizikalno - kemijskih pokazatelja i izdašnosti. Ispitivani su sljedeći izvori: Sitnik, Cerovica, Radina Vas, Liješće, Kordići Žumberački. Analize su provedene dva puta u različitim godišnjim dobima, prvi puta u studenom 2010., a drugi put u veljači 2011. Rezultati mikrobioloških analiza vode sa izvora u studenom pokazuju velika odstupanja u odnosu na MDK propisane Pravilnikom, kao i u usporedbi s rezultatima analiza koje su provedene nekoliko mjeseci kasnije (u veljači).A rapid changes of water quality in karst springs during quick recharge with microbiologically contaminated water is an important concern for drinking water suppliers and users. Purpose of this study was to examine the compatibility of water from five selected springs in Žumberak - Samoborsko gorje Nature Park area with microbiological standards according to regulations about health validity of drinking water (NN 47/08) and to estimate condition of springs by in situ measurements of basic physico – chemical parameters and discharge values. The selected springs were: Sitnik, Cerovica, Radina Vas, Liješće, Kordići Žumberački. Analyses were performed twice, each during different season, the first in November 2010. and the second in February 2011. Results of microbiological analysis of spring waters showed large exceeding in comparison to Maximum Allowable Value stated in the Drinking Water Standards, as well as in comparison with the results of analysis that were conducted several months later (in February)
