Ukuncipha kwamanzi angaphansi komhlaba kubangela ukuthi imithombo yome, okuthinta ukukhiqizwa kokudla kanye nokutholakala kwamanzi asekhaya. Ukumba imithombo ejulile kungase kuvimbele ukomiswa kwemithombo—kulabo abakwaziyo ukuyikhokhela nalapho izimo ze-hydrogeologic zikuvumela khona—nokho ukuthi ukubhoboza ukujula kangaki akwaziwa. Lapha, sihlanganisa izigidi ezingu-11.8 zezindawo ezinemithombo yamanzi angaphansi komhlaba, ukujula nezinjongo e-United States yonkana. Sibonisa ukuthi imithombo evamile yakhiwa ngokujulile izikhathi ezingu-1.4 kuya kwezingu-9.2 ngaphezu kokuba yakhiwa ibe ncane kakhulu. Ukujula kwamachibi akutholakali yonke indawo kuzo zonke izindawo lapho amanzi angaphansi komhlaba ehla khona, okusho ukuthi imithombo engashoni isengozini yokoma uma ukuncipha kwamanzi angaphansi komhlaba kuqhubeka. Siphetha ngokuthi ukumbiwa kwemithombo ejulile okusabalele kumelela igebe elingalawuleki lokuncipha kwamanzi angaphansi komhlaba okunqunyelwe izimo zenhlalo-mnotho, i-hydrogeology kanye nekhwalithi yamanzi angaphansi komhlaba. Imithombo yamanzi angaphansi komhlaba e-United States ingaphansi kwengcindezi enkulu kunangaphambili ngenxa yezimo zesomiso kanye nesidingo esikhulayo, kodwa imvelo ebanzi yokumba ukujula ibingakabikwa. Lokhu kuhlaziya kuhlanganisa imithombo yamanzi angaphansi komhlaba ecishe ibe yizigidi eziyi-12 kulo lonke elase-United States ukuze kutholwe ubungozi bamanzi kanye nokusimama.
