Beveik 100 proc. Lietuvos geriamojo vandens gaunama i\u0161 po\u017eemini\u0173 sluoksni\u0173, taigi Lietuva \u2013 viena i\u0161 nedaugelio pasaulio \u0161ali\u0173, galin\u010di\u0173 pasigirti tokiu \u0161variu ir kokybi\u0161ku vandeniu. \u0160is faktas tampa dar svarbesnis \u017einant, kad kai kuriose pasaulio vietose \u0161varus vanduo sunkiai prieinamas arba stipriai u\u017eter\u0161tas, o kai kur jau kyla konflikt\u0173 d\u0117l vandens i\u0161tekli\u0173.

\u201eLietuvoje po\u017eeminis vanduo kaupiasi po\u017eeminiuose sluoksniuose, susiformavusiuose per t\u016bkstantme\u010dius. Geografin\u0117 pad\u0117tis, klimato s\u0105lygos ir geologin\u0117 s\u0105ranga l\u0117m\u0117 palankias s\u0105lygas formuotis \u0161variam po\u017eeminiam vandeniui. Vis d\u0117lto \u0161is i\u0161teklius n\u0117ra begalinis, tod\u0117l b\u016btina j\u012f saugoti\u201c, \u2013 sak\u0117 Hidrogeologijos skyriaus ved\u0117ja Rasa Radien\u0117.

Beje, mokslininkai nustat\u0117, kad seniausias Europoje po\u017eeminis vanduo sl\u016bgso Lietuvoje, 1 100 m gylyje, ir jo am\u017eius yra 1 milijonas 157 t\u016bkstan\u010diai met\u0173.

O ar galite \u012fsivaizduoti vanden\u012f, kuris \u017eem\u0117s gelm\u0117se buvo \u012fkalintas milijardus met\u0173 ir niekada nesiek\u0117 pavir\u0161iaus? Vienas \u012fsp\u016bdingiausi\u0173 atradim\u0173 \u2013 beveik pustre\u010dio kilometro gylyje Kanadoje, Ontarijo provincijoje aptiktas vanduo, kurio am\u017eius siekia apie 2 milijardus met\u0173. \u0160is uolienose \u012fkalintas vanduo yra seniausias iki \u0161iol atrastas vanduo \u017dem\u0117je. Vanduo per vis\u0105 \u0161\u012f laik\u0105 neprasiskverb\u0117 \u012f pavir\u0161i\u0173 ir i\u0161laik\u0117 savo chemin\u0119 sud\u0117t\u012f.

Paleovanduo, dar vadinamas senoviniu vandeniu, yra unikalus gamtos rei\u0161kinys, kai vanduo milijonus ar net milijardus met\u0173 i\u0161b\u016bna izoliuotas po \u017eeme. Jis gali b\u016bti u\u017esikonservav\u0119s uolienose ar ledynuose (toks yra Vostoko e\u017eeras Antarktidoje).
\u012edomu tai, kad po\u017eeminio vandens jud\u0117jimas vyksta itin l\u0117tai \u2013 neretai vos vien\u0105 metr\u0105 per metus. Kod\u0117l? Nes vandeniui tenka keliauti per tankias uolienas ir j\u0173 mikroply\u0161ius bei poras. D\u0117l \u0161ios prie\u017easties vanduo lieka izoliuotas milijonus met\u0173 ir i\u0161laiko unikali\u0105 savo sud\u0117t\u012f, o j\u012f atrad\u0119 mokslininkai gauna ret\u0105 galimyb\u0119 pa\u017evelgti \u012f tolim\u0105j\u0105 \u017dem\u0117s praeit\u012f.
