20.500.12556/RUL-164561 Poskus ocene kakovosti podtalnice v vodonosniku ob Mislinji A test case of assessing of groundwater quality in the Mislinja aquifer Vodonosnik ob Mislinji zaradi majhne izdatnosti in dejstva, da se ne uporablja za vodooskrbo, ni vključen v redni državni monitoring kakovosti podzemnih voda. V članku na primeru devetih vzorčnih mest (zasebnih vodnjakov in vrtin) analiziramo vrednosti osnovnih fizikalno-kemijskih parametrov vode, na podlagi katerih preliminarno ocenjujemo njeno kakovost. Ugotavljamo, da se v podtalnici odražajo antropogeni vplivi, ki so izrazitejši v bližini območij strnjene kmetijske obdelave ter ob večjih naseljih. Pri večini vzorcev so prisotne povišane vrednosti nitratov in kloridov, pri nekaterih pa se v višjih koncentracijah pojavljajo tudi druga merjena onesnažila. Glede na aktualni Pravilnik o pitni vodi je kar pet od devetih vzorcev neustreznih, oziroma zgolj pogojno ustreznih, kar pomeni, da je podtalnica v vodonosniku ob Mislinji morda že preveč onesnažena, da bi nanjo lahko računali kot na možni rezervni vodni vir za vodooskrbo. The Mislinja aquifer is not included in regular national groundwater quality monitoring due to its low yield and the fact that it is not used for water supply. For this paper, nine sampling sites (private wells and boreholes) were used to analyse the basic physico-chemical parameters of the water, serving as a basis for a preliminary assessment of water quality. We found that the groundwater reflects anthropogenic influences, which are more pronounced in the vicinity of areas of concentrated agricultural activity and in the vicinity of large settlements. Most samples show elevated levels of nitrates and chlorides, while some samples also show elevated levels of other measured pollutants. According to the current Rules on drinking water, five out of nine samples are unsuitable or only conditionally suitable, which means that the groundwater in the Mislinja aquifer may already be too polluted to be considered as a possible backup source for water supply. hidrogeografija podtalnica vodni viri varstvo okolja kakovost voda Slovenija Mislinja hydrogeography groundwater groundwater quality environmental protection Slovenia true false false Slovenski jezik Angleški jezik Neznano 2024-10-30 13:55:50 2024-10-30 13:55:55 2024-11-22 14:54:50 0000-00-00 00:00:00 2022 0 0 Str. 5-56 [Št.] 57 2022 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 556:502/504(497.4Mislinja) 0354-0596 10.4312/dela.57.5-56 142234627 https://journals.uni-lj.si/Dela/article/view/12282/10984 1 fc143ff8-96bd-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195082 https://journals.uni-lj.si/Dela/article/view/12282/10985 1 fc3681ef-96bd-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195083 Breznik,+Trobec.pdf Breznik,+Trobec.pdf 1 EB77A12D2105AAF9E1EEF8B85681D3C8 1296770a4d1e203ae2c661bedd15692fea17a037265ce890d6ceaa1c0760d450 0c406eb6-96be-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195084 Filozofska fakulteta Dela 0 0 0
