Rangahau ā-Motu mō te Tango Matūkai me ngā Hangarau Tuarua
Kei te tirotirohia e te EPA ngā huarahi whai hua, whai hua hoki mō te tango matūkai i ngā wāhi maimoatanga tūmatanui (POTW). Hei wāhanga o te rangahau ā-motu, i whakahaerehia e te tari tētahi rangahau o ngā POTW i waenga i te tau 2019 ki te 2021.

Kua tāpirihia e ētahi POTW he tukanga maimoatanga hou hei tango i ngā matūkai, engari kāore pea ēnei whakapainga e taea te utu, e hiahiatia rānei mō ngā whare katoa. Kei te āwhina tēnei rangahau i te EPA ki te ako mō ētahi atu huarahi e whakaitihia ai e ngā POTW ā rātou tukunga matūkai, me te arotau i ngā mahi whakahaere me te tiaki, me te kore e nui ngā whakapaunga whakapaipai. E toru ngā whāinga matua o te rangahau:

Tikina ngā raraunga ā-motu mō te tango i ngā matūkai.
Whakatenatenahia te whakapai ake i te mahi POTW me te iti ake o te utu.
Whakaratohia he wāhi whakawhitiwhiti kōrero mō ngā kaipupuri hea ki te whakapuaki i ngā tikanga pai.
Ngā Painga ki ngā POTW
Ka puta i te rangahau ēnei āhuatanga:
Āwhina i ngā POTW ki te arotau i te tango matūkai mā te whakarato i ngā mōhiohio mahi me te whai huatanga mai i ngā momo POTW rite kua tutuki kē i ngā huarahi angitu, utu-whai hua hoki ki te tango matūkai.
Hei rauemi raraunga hou nui puta noa i te motu mō te tango matūkai hei āwhina i ngā kaipupuri whakaaro ki te aromatawai me te whakawhanake i ngā uara whakaiti matūkai ka taea.
Whakaratohia he pātengi raraunga whai kiko mō te mahi tango matūkai mā ngā POTW, ngā kawanatanga, ngā kairangahau mātauranga, me ētahi atu rōpū whai pānga.
Kua kite kē ngā POTW i ngā painga o te arotautanga iti te utu. I te tau 2012, ka tīmata te Tari Kounga Taiao o Montana ki te whakangungu i ngā kaimahi POTW i te kawanatanga mō te tango me te arotautanga o ngā matūkai. Nā ngā POTW i whai wāhi katoa ā rātou kaimahi ki te tukanga arotautanga i tino whakaiti i ā rātou tukunga matūkai.

Kua Oti te Tango Matūkai puta noa i te Motu
Ko ngā hua tuatahi o te pātai tātari e āwhina ana ki te whakaatu i tētahi āhuatanga nui o te Rangahau ā-Motu: ka taea te tango i ngā matūkai pai ake e ngā momo POTW katoa. E whakaatu ana ngā hua o te rangahau tae noa ki tēnei wā neke atu i te 1,000 ngā POTW me ngā momo maimoatanga koiora rerekē (tae atu ki ngā hangarau maimoatanga tuku iho me ngā hangarau maimoatanga matatau) ka taea te whakatutuki i te hauota katoa o te parahanga o te 8 mg/L me te whākawa katoa o te 1 mg/L. Kei roto i te pikitia i raro nei ngā POTW me te taupori e mahi ana ki te 750 tāngata neke atu rānei, me te kaha rere hoahoa o te 1 miriona karani ia rā neke atu rānei.
