Ko te pikinga ake o te hiahia mō te wai ma kei te take i te korenga o te wai puta noa i te ao. I te mea kei te piki haere tonu te taupori, me te heke haere o te tangata ki ngā tāone nui, he maha ngā wero e pā ana ki ngā ratonga wai e pā ana ki ā rātou mahi tuku wai me te maimoatanga. Kāore e taea te wareware i te whakahaere wai ā-rohe, nā te mea e whakatau ana te Kotahitanga o ngā Whenua o te Ao ko ngā tāone nui te take o te 12% o ngā tangohanga wai māori katoa. [1] Haunga te pikinga ake o te hiahia mō te wai, kei te raru ngā ratonga wai ki te whai i ngā ture hou e pā ana ki te whakamahinga wai, ngā paerewa maimoatanga wai para, me ngā mahi pumau, me te aro atu ki ngā hanganga tawhito me te iti o te pūtea.
He maha hoki ngā ahumahi e pāngia ana e te korenga o te wai. He maha ngā wā ka whakamahia te wai i roto i ngā tukanga hangahanga hei whakamatao me te horoi, ā, me tukatuka te wai para i puta mai i mua i te whakamahinga anō, i te tukunga rānei ki te taiao. He tino uaua ki te tango i ētahi poke, pērā i ngā matūriki hinu angiangi, ā, ka hanga pea he toenga e hiahia ana kia rongoatia motuhake. Me whai hua te utu o ngā tikanga maimoatanga wai para ahumahi, ā, me kaha ki te rongoā i ngā rahinga nui o te wai para i ngā pāmahana me ngā taumata pH rerekē.
He wāhanga nui te whakatutukitanga o te tātari whai hua teitei ki te whakawhanake i te whakatupuranga hou o ngā otinga maimoatanga wai. He tikanga maimoatanga tino whai hua, he penapena pūngao hoki ngā kiriuhi tātari matatau, ā, kei te whakawhanake tonu ngā kaihanga i ngā hangarau hou hei whakatutuki i ngā hiahia o ngā whare ahumahi me ngā whare ā-tāone, me te noho whakamua i te taiao ture e huri haere ana mō te tiaki me te whakamahi anō i te wai.
Ka pāngia te tuku wai me te kounga o te wai e te huringa āhuarangi. Ka taea e ngā awha nui me ngā waipuke te kino i ngā tuku wai, ka piki ake te horapa o ngā poke, ā, ka taea e te pikinga o ngā taumata o te moana te arahi ki te pikinga o te urunga mai o te wai tote. Kei te whakaitihia te wai e wātea ana e te tauraki roa, ā, he maha ngā whenua o te Hauāuru, tae atu ki a Arizona, California me Nevada, e whakatakoto ana i ngā here tiaki taiao nā te korenga o te wai i te Colorado River Basin.
Me whakapai ake me te haumi hoki ngā hanganga wai. I roto i tana rangahau hou mō ngā hiahia mō ngā rohe wai ma, i kitea e te Tari Tiaki Taiao o Amerika (EPA) e $630 piriona te moni e hiahiatia ana mō ngā tau 20 e whai ake nei hei whakarato i te wai ma e ranea ana, me te 55% o taua pūtea e hiahiatia ana mō ngā hanganga wai para. [2] Ko ētahi o ēnei whakaritenga i ahu mai i ngā paerewa maimoatanga wai hou, tae atu ki te Ture Wai Inu Haumaru me te ture e whakatakoto ana i ngā taumata mōrahi o ngā matū pēnei i te hauota me te whākōkī. He mea nui te tukanga tātari whai hua hei tango i ēnei poke me te whakarato i tētahi puna wai haumaru, ma hoki.
Kāore ngā ture PFAS e pā noa ki ngā paerewa tuku wai, engari ka pā tika hoki ki te hangarau tātari. Nā te mea he pakari ngā matū whai fluorinated, kua noho hei rauemi noa i roto i ētahi kiriuhi, pērā i te polytetrafluoroethylene (PTFE). Me whakawhanake e ngā kaihanga tātari kiriuhi ētahi atu rauemi kāore i roto he PTFE, he matū PFAS rānei hei whakatutuki i ngā whakaritenga ture hou.
I te mea he nui ake ngā pakihi me ngā kāwanatanga e whakamahi ana i ngā kaupapa ESG kaha ake, ka noho ko te whakaiti i ngā tukunga hau kati kōtuhi hei kaupapa matua. Ko te whakaputa hiko tētahi o ngā pūtake nui o ngā tukunga, ā, ko te whakaiti i te whakapaunga pūngao whānui he huarahi nui hei whakatutuki i ngā whāinga whanaketanga tauwhiro.
E ai ki te pūrongo a te Environmental Protection Agency, ko ngā whare horoi wai inu me ngā whare horoi wai para te nuinga o te wā e whakamahi ana i te pūngao i roto i ngā kaunihera, e 30 ki te 40 ōrau o te whakamahinga pūngao katoa. [3] Kei roto i ngā rōpū rauemi wai, pērā i te American Water Alliance, ngā ratonga wai e whakapau kaha ana ki te whakaiti i ngā tukunga hau kati kōtuhi i roto i te rāngai wai mā roto i ngā rautaki whakaiti i te huringa āhuarangi me te whakahaere wai pumau. Mō ngā kaihanga tātari membrane, he mea nui te whai huatanga o te pūngao ina whakamahi ana i tētahi hangarau hou.
Ka taea e mātou te whakarato i ngā momo pūoko hei aroturuki i ngā tawhā rerekē o te kounga wai.
He mea hanga tēnei pūoko tirotiro ki te rauemi PTFE (Teflon), he ātete ki te waikura, ā, ka taea te whakamahi i roto i te wai moana, i te ahumoana me ngā wai he pH teitei me te waikura kaha.
