Abstract

Oko 50% teritorija Republike Hrvatske je s hidrogeološkog stanovišta okarakterizirano kao krš. Zbog izrazito neravnomjerne raspodjele provodnika kroz koje voda protječe u kršu, modeliranje toka i pronosa zagađivala je izrazito složeno. Pojava zagađivala u krškim vodonosnicima može biti posljedica pojačane poljoprivredne djelatnosti, propusnih septičkih jama, otpadnih voda naselja i industrije kao i nekih drugih izvora zagađivala. Zagađenja pridonose smanjenju količina vode prikladne za potrebe vodoopskrbe. Kako bi se spriječilo širenje oblaka zagađenja, provode se istraživanja s ciljem određivanja položaja izvora zagađenja i njegovog saniranja in situ. U tu svrhu, sve češće se koriste i numerički modeli koji su zasnovani na obradi rezultata hidrogeoloških mjerenja prilikom probnih crpljenja iz zdenaca. U ovom radu je prikazan test integralnog probnog crpljenja primijenjen na lokaciji Bokanjac – Poličnik, koji je proveden u sklopu cjelovitog hidrogeološkog istraživanja vodonosnika. Test se sastoji od dugotrajnog crpljenja, mjerenja razine podzemne vode i istovremenog sistematičnog uzimanja uzoraka zahvaćene vode na kojima se provode odgovarajuće kemijske analize.

Abstract (english)

About 50% of the territory of the Republic of Croatia is from the hydrogeological point of view characterized as karst. Conductors in the karst are very irregularly distributed and this is the reason why the flow and transport modelling is extremely complex and unreliable. The occurrence of pollutants in karst aquifers may be the result of increased agricultural activity, permeable septic tanks, wastewater from settlements and industry, as well as some other sources of pollutants. Pollution contributes to reducing the amount of water suitable for water supply needs. In order to prevent the spread of pollution, research is being conducted with the aim of determining the position of the pollution source and its remediation in situ. In this context, numerical models which process the results of hydrogeological measurements collected during pumping tests on exploitation wells are increasingly used. This paper presents an integral test pumping test applied at the Bokanjac - Poličnik site, which was conducted as part of a comprehensive hydrogeological survey of aquifers. The test consists of long-term pumping, measurements of groundwater level and simultaneous systematic sampling of captured water on which appropriate chemical analyzes are performed.
