Nyob ntawm nws permeability, cov dej tuaj yeem nce dej ntawm tus nqi ntawm 50 feet hauv ib xyoos mus rau 50 ntiv tes hauv ib puas xyoo. Lawv muaj ob qho tib si recharge thiab tso tawm tsam. Ib cheeb tsam recharge feem ntau tshwm sim ntawm qhov siab siab qhov twg los nag, snowmelt, pas dej los yog dej ntws ntws mus rau hauv av. ntxiv tus dej hiav txwv.
Kuj nug, aquifers puas vau?
Feem ntau ntawm cov ntiaj chaw muaj dej tshiab nyob hauv av. Aquifers khaws dej zoo li daim txhuam cev, tuav nws hauv qhov chaw nruab nrab ntawm pob zeb, xuab zeb, pob zeb thiab av nplaum. Tam sim no dej ntau tau nqus los ntawm qee qhov cov dej hais tias cov underground chaw yog kev sib tsoo thiab qhov chaw ntawm lub ntiaj teb tau hloov mus tas li.
Cov aquifers puas tuaj yeem muab ntxiv?

AFC poob qis vim qhov tso zis ntau ntxiv vim muaj kev sib kis. Tus nqi ruaj khov yog kis mus rau ntau dua thiab ntau dua units ntawm cov khoom tso tawm raws li cov zis ntau ntxiv. AVC nce raws li cov zis nce vim qhov txo qis rov qab los. Vim qhov txo qis rov qab mus rau kev ua haujlwm, nws raug nqi ntau dua los tsim txhua chav ntxiv ntawm cov zis
