Whakarāpopototia te tuhinga:  I kaukau tētahi kaitautoko wai ma i te rā o te Ao i te awa poke o Gowanus Canal o New York City, he wāhi i tohua e te kāwanatanga ā-rohe he tino poke, engari i mutu i te haurua. I mau a Christopher Swain i tētahi kākahu paruru kowhai i a ia e eke ana ki runga i tētahi taiepa, ā, ka uru ki te wai i te 2pm o te Wenerei i Brooklyn, engari i oti i a ia te rua tuatoru o te maile o te awa 1.8-mile. I kaukau ia mo te haora ki roto i te awa hei akiaki i te horoi taiao i te mutunga ka hinga ki te poke o te wai na te mea ko te wheako he rite ki te'rere' i roto i te peera paru. Ko Christopher Swain, he kaitohutohu wai ma, i eke ki te kaukau 1.8-maero i roto i te Gowanus Canal paitini, kua tohua hei tino poke e te Tari Tiaki Taiao, ki te akiaki i tana horoi. Ko te kaikawe, i mutu i te rua tuatoru o te maero ki te kaukau, ka whakakorikori i te waikawa hydrogen peroxide kia kore ai te wai poke e uru ki raro i tona kaki. I kii a Swain, i kaukau i mua i nga awa o Hudson me Columbia, me tere te horoi i te Gowanus Canal, i tapaina hei waahi Superfund e te EPA. 'Ko te mea pea te nekehanga haumaru i tenei wa,' i kii ia, e ai ki a Reuters, engari i oati ki te kaukau i te awa katoa i tetahi ra. 'Kei te hiahia au ki te whakamārama, kaore he tangata e ki mai ki ahau kia mutu,' ka haere tonu a Swain, a ka mea ko te ahua o te rangi kino i whai wāhi ki tana whakatau. Ka mea te kaitohutohu, 'Kāore i te haumaru te kaukau ki reira,' e ai ki a Gothamist. I kii ia ko te reka o te wai 'Pērā ki te paru, te poaka, te tarutaru, te horoi me te penehi'. Ko te awa o te rau tau 19 he huarahi waka nui, engari i tenei wa kua poke i nga tukunga ahumahi me te waipuke, na te ture, me horoi. E ai ki te Tari Tiaki Taiao a te kāwanatanga, kei roto i ngā poke ko ngā PCB, i rāhuitia i te US i te tau 1979. I whakatupato ia ki a Swain kia kaua e kaukau, i te tuku korero i runga i tana kaute Twitter e kii ana 'ka tino taunakihia te kaukau' i roto i te waahanga wai. I tukuna e te tari he aratohu i te tau 2011 e kii ana ko nga tangata...
I whakakakahu a Christopher Swain i te kākahu paruru ki te kaukau i roto i te Gowanus Canal. Ko te awa o Brooklyn he wāhi rongonui mo te ururua ahumahi paitini. Tata ki te 377 miriona karetao o te wai ururua maroke i ringihia i ia tau. I mutu a Swain i te rua hautoru o te maero ki te haerenga 1.8-maero, a ka mea he rite ki te'rere ki roto i te peera paru' I whakamakuku te kaiwaiata i te waikura, ā, he pire motuhake i te ringa hei whawhai ki te wai poke e uru ana ki roto i tōna tinana, ā, ka mate ai ia. I akiaki ia kia tere ake te horoi i te awa, i whakaritea mo te whakakorenga i te tau 2017.
