Hidrokemijski laboratorij Zavoda za hidrogeologiju i in\u017eenjersku geologiju Hrvatskog geolo\u0161kog instituta formiran je u drugoj polovici 90-tih godina pro\u0161log stolje\u0107a. U laboratoriju se mjere fizikalni, fizikalno-kemijski i kemijski parametri te omjeri stabilnih izotopa kisika-18 (d18<\/sup>O) i deuterija (dD) u uzorcima podzemne vode, rijeka, jezera i ki\u0161nice.<\/p>\n

U svijetu postoji dugogodi\u0161nja praksa kori\u0161tenja hidrokemijskih metoda koje uklju\u010duju mjerenje fizikalnih, fizikalno-kemijskih i kemijskih pokazatelja za rje\u0161avanje hidrogeolo\u0161kih i ekolo\u0161kih problema. Mjerenjem sadr\u017eaja prirodnih stabilnih i radioaktivnih izotopa u kombinaciji s rezultatima hidrokemijskih mjerenja rje\u0161ava se problematika porijekla podzemne vode, mije\u0161anja razli\u010ditih voda, utjecaja povr\u0161inskih voda na podzemne vode, utvr\u0111ivanje geokemijskih procesa koje se odvijaju u vodonosniku i koji utje\u010du na kakvo\u0107u podzemne i povr\u0161inske vode.<\/p>\n

Pomo\u0107u prirodnih obilje\u017eiva\u010da (trasera), me\u0111u kojima se isti\u010de izotopni sastav vode, mogu\u0107e je, izme\u0111u ostaloga, odrediti vrijeme zadr\u017eavanja vode u podzemlju. Osim prirodnih obilje\u017eiva\u010da, za odre\u0111ivanje smjera i brzine te\u010denja podzemne vode koriste se umjetni obilje\u017eiva\u010di (naj\u010de\u0161\u0107e boje) kao \u0161to su npr. Na-flourescein i naftionat.<\/p>\n
