Abstract

Zadatak ovog rada bio je ocijeniti kakvoću podzemne vode na priljevnom području
planiranog vodocrpilišta Črnkovec. Razlog tomu istraživanju leži u činjenici da se podzemna voda toga područja planira iskoristiti za potrebe vodoopskrbe. Podaci potrebni za ocjenu kakvoće prikupljeni su od strane Zavoda za javno zdravstvo nakon čega je uslijedila
usporedba prikupljenih kemijskih analiza u odnosu na maksimalne dozvoljene koncentracije
(MDK). Na osnovi rezultata istraživanja izdvojeno je sedam (7) `kritičnih` parametara iz
sedam piezometara koji prelaze MDK u razdoblju 2008-2012. godine. Piezometri su smješteni
na području Kosnice i Velike Gorice, a izdvojeni parametri su: mikrobiološki pokazatelji -
ukupni koliformi (1), broj kolonija pri 37 stupnjeva Celzijusa (2) i broj kolonija pri 22 stupnja Celzijusa (3), te kemijski pokazatelji - amonij (4), mangan (5), pesticidi - ukupni pesticidi (6) i željezo (7). Najviše
zagađenja dolazi iz nepostojeće i/ili nesanirane podzemne kanalizacijske mreže,
poljoprivredne aktivnosti, divljih odlagališta i uopće velike koncentracije stanovništva. Prema
Uredbi o standardu kakvoće voda (NN 73/13) može se zaključiti da je kakvoća podzemne
vode uvjetno dobrog kemijskog sastava. Također, bitno je pristupiti postupcima sanacije ili
pročišćavanja u svrhu smanjenja zagađenja.

Abstract: The aim of this study was to evaluate the quality of groundwater in the inflow area of the
planned water well Črnkovec. The reason for this study lies in the fact that the groundwater of
that area is planned to be used for water supply purposes. The data required for quality
assessment were collected by the Institute of Public Health followed by a comparison of the
collected chemical analysis in relation to the maximum permissible concentracion (MPC).
Based on the results of the research it has been allocated seven (7) `critical` parameters from
seven piezometers exceeding MPC in the period of 2008-2012. Piezometers are located in the
area of Kosnica and Velika Gorica, and separate parameters are: the microbiological
parameters – total califorms (1), the number of colonies at 37 degrees Celsius (2) and the number of
colonies at 22 degrees Celsius (3), and chemical parameters – ammonium (4), manganese (5), pesticides –
total pesticides (6) and iron (7). The most pollution comes from non-existent and/or nonrepaired
underground sewer network, agricultural activities, illegal dumping and even large
concentracions of population. According to the Regulation on water quality standards (NN
73/13) it can be concluded that the quality of groundwater conditionally has good chemical
composition. Also, it is important to access the methods of rehabilitation or purification in
order to reduce pollution
