Quality of groundwater of Samobor's alluvial aquifer : master's thesis

U ovom diplomskom radu predstavljena je kakvoća podzemne vode samoborskoga aluvijalnog vodonosnika. Osim kakvoće, prikazane su simulacije trasiranja čestica unatrag za niske i visoke vode vodocrpilišta Strmec i Šibice. Kakvoća podzemne vode opisana je grafovima napravljenim u Excelu dok dok su simulacije trasiranja napravljene u Visual MODFLOW programu. Dobiveni rezultati ukazuju na loše stanje kakvoće podzemne vode samoborskoga aluvijalnog vodonosnika. Iz simulacija su vidljive trase kretanja čestica te važnost određenih područja i piezometra pri definiranju kakvoće podzemne vode u promatranom razdoblju. Iz usporedbe trasa kretanja čestica i lokacija promatranih piezometra s katastrom onečišćivača istraživanog područja, može se pretpostaviti kako antropogeni utjecaj velikim dijelom narušava kakvoću podzemne vode i ugrožava daljnje crpljenje pitke vode na crpilištima samoborskog aluvijalnog vodonosnika.Abstract: This thesis presents the quality of groundwater of Samobor's alluvial aquifer. Except quality, thesis presents simulations of backword particle tracking for low and high waters of waterwells Strmec and Šibice. The quality of groundwater is described by graphs made in Excel while particle tracking simulations were created in Visual MODFLOW program. The obtained results indicate a poor state of groundwater quality in Samobor's alluvial aquifer. Simulations show visible paths of movement of particles and importance of certain areas and piezometers which define the quality of groundwater in the observed period. From a comparison of the paths of movement of particles and the locations of piezometers with the cadastre of pollutants of the study area, it can be assumed that the anthropogenic influence has a large impact in destroying the quality of groundwater and threatens further pumping of drinking water in waterwells of Samobor's alluvial aquifer
