Ka aromatawaihia te kounga o te wai awa e te Tari Taiao mā te kaupapa Aromatawai Kounga Whānui (GQA), ā, he mea nui kia whakahaeretia ngā matū kino pea i roto i te awa. He matūkai nui te haukini mō ngā tipu me ngā rimurimu e noho ana i roto i te wai awa. Heoi, ina huri te pāmahana o te awa, ka huri te haukini kua whakakōkīhia hei hau haukini kāore i te whakakōkīhia. He mea whakamate tēnei ki ngā ika me ētahi atu mea ora i roto i te awa, nō reira he mea nui kia aroturuki tonu i ngā taumata haukini.
He mea nui anō hoki te kounga o te wai mō ngā whare rongoā wai e whakamahi ana i te wai awa hei pūtake. Ka raru pea te tukanga patu huakita i te nui o te haukini i roto i te wai. Mā te ine angitu i ngā taumata haukini i roto i te wai awa i te tomokanga o te whare rongoā wai, ka taea e te whakahaere te tiaki i te putanga o te tomokanga. I ētahi whakamahinga, ka taea te kati i te tomokanga ina tae ngā taumata haukini ki ngā taumata tino teitei.
He utu nui, he uaua hoki ngā tikanga aroturuki haukini o nāianei, he whakamahi i ngā irahiko whiriwhiri-katote me ngā matū utu nui, he paitini, he uaua hoki ki te whakahaere. Kāore hoki ēnei aroturuki i te motuhake, ā, me whakatikatika tonu kia urutau ki ngā hiahia rerekē, pērā i te maimoatanga wai para, te maimoatanga wai inu me te ine i ngā taumata haukini i roto i te wai awa. Ko ngā irahiko whiriwhiri-katote me whakatikatika i ia rā me ngā matū.
Ka karohia e te aroturuki haukini HONDE ngā wero o ngā aroturuki haukini tuku iho mā te whakamahi i tētahi huarahi tino ahurei. Ka hurihia te haukini hei matū monochloramine pumau i te kukū e ōrite ana ki te taumata haukini taketake. Kātahi ka inehia te kukū chloramine mā te whakamahi i tētahi pūoko membrane polarographic me tētahi urupare raina whiriwhiri ki te chloramine. Mā te matū tauhohenga ka tino pai te aro o te aroturuki ahakoa i ngā taumata haukini tino iti (ppb).
He māmā noa iho te matū matū, he iti te utu, ā, he iti hoki te tere whakamahinga. Nō reira, he tino iti te utu o te mana pupuri.
Kei te whakamahi kē ngā kamupene wai nunui o te UK me ētahi taiwhanga kua whakamanahia e te Environment Agence i ngā aroturuki HONDE hei aroturuki tika i ngā taumata haukini i roto i te wai awa. Mā tēnei pūnaha haukini hou mai i Analytica Technologies ka taea e ngā kaiwhakamahi te whakamahi i tētahi aroturuki he māmā ki te whakahaere, he iti te utu ki te hoko, he iti te whakahaere, ā, kāore he pokanoa ki te ine.
