Ma nā puʻu ʻōwili o Crestview Valley, ua ulu maikaʻi kahi mahiʻai ʻohana i kapa ʻia ʻo Green Pastures ma lalo o nā lima akahele o ka mahiʻai ʻelemakule, ʻo David Thompson, a me kāna kaikamahine, ʻo Emily. Ua ulu lākou i nā mea kanu ikaika o ka kulina, ka soybeans, a me nā ʻano mea kanu like ʻole, akā e like me nā mahiʻai he nui, ua hakakā lākou me nā mana wānana ʻole o ke kūlohelohe. ʻO nā mea ʻino, nā maloʻo, a me ke aniau wānana ʻole nā pilikia i kū pinepine iā lākou. Eia naʻe, ʻo ke ʻano o kā lākou lako wai ka mea i hopohopo nui iā lākou.
ʻO Crestview Valley kahi home o kahi loko mālie i hānai ʻia e kahi kahawai liʻiliʻi, ʻo ia ke koko ola no Green Pastures. No ka mālama ʻana i ke olakino o kā lākou mau mea kanu, ua ʻike ʻo David he mea nui ka mālama ʻana i ke kiʻekiʻe o ka wai, akā ʻaʻohe ona ala hilinaʻi e ana i nā pae oxygen i hoʻoheheʻe ʻia i loko o ka loko. ʻO nā mea ʻawahia mai ka ʻāina mahiʻai a puni a me nā hopena o ka loli o ke aniau ua hoʻoweliweli i ko lākou wai, ka mea i hoʻopilikia pololei i kā lākou hua. Me ka huhū a me ka hopohopo e pili ana i ke olakino o kā lākou mau mea kanu, ua hoʻohana pinepine ʻo David i nā hola e hoʻāʻo nei e nānā i ka maikaʻi o ka wai ma ke kuhi ʻana.
I kekahi awakea lā, ua holo mai ʻo Emily i luna o ka puʻu, me ka pīhoihoi e pālahalaha ana mai kona helehelena. "E Pāpā, ua lohe au e pili ana i kēia mau mea ʻike oxygen hoʻoheheʻe optical hou! Manaʻo ʻia lākou e lilo i mea hoʻololi pāʻani no nā mahiʻai e like me mākou!"
Me ka hoihoi akā kānalua, ua hoʻolohe ʻo David iā Emily e wehewehe ana i ke ʻano o ka hana ʻana o kēia mau mea ʻike. ʻAʻole e like me nā hoʻokolohua kemika kuʻuna i hāʻawi i nā hopena lohi a me ka ʻike loea e pono ai, ua hāʻawi nā mea ʻike oxygen hoʻoheheʻe optical i nā heluhelu koke a mau. Ua hoʻohana lākou i ka ʻenehana holomua e ana i ka mālamalama i omo ʻia e nā molekala oxygen i loko o ka wai, e hāʻawi ana i ka ʻikepili manawa maoli o nā mahiʻai e pili ana i ka maikaʻi o ko lākou wai. Paipai ʻia e kēia ʻike, ua hoʻoholo lākou e hoʻopukapuka i kahi mea ʻike.
He ʻIke Hoʻololi
Me ka mea ʻike oxygen hoʻoheheʻe optical i hoʻokomo ʻia ma kahi kokoke i ka loko, ua nānā ʻo Emily i ka ʻikepili ma kāna kelepona akamai. I ka lā mua loa, ua ʻike lākou ua haʻahaʻa nā pae oxygen hoʻoheheʻe ma mua o ke kūpono. Me kēia ʻike, ua hana wikiwiki ʻo Emily lāua ʻo David, me ka hoʻohui ʻana i nā aerators i ka loko. I loko o kekahi mau lā, ua hōʻike ka mea ʻike i ka piʻi ʻana o nā pae oxygen.
I ko lākou nānā ʻana i ka wai i nā pule ma hope mai, ua kōkua ka mea ʻike iā lākou e ʻike i nā ʻano a me nā loli o ke kau. I ka hopena o ke kauwela, i ka wā i hoʻomaka ai ka wai e mahana, ua ʻike lākou i ka emi ʻana o ka oxygen i hoʻoheheʻe ʻia. Ua hoʻoikaika kēia iā lākou e hoʻokomo i nā mea kanu malu a puni ka loko e hoʻomaʻalili i ka wai, e hana ana i kahi nohona olakino no ke ola wai a me ka hōʻoia ʻana ua loaʻa i kā lākou mau mea kanu ka maikaʻi o ka wai.
Nā ʻOhi Nui
Ua ʻike maopopo ʻia nā pono maoli o ka sensor i ka wā ʻohiʻohi. Ua ulu nui nā mea kanu e like me ka wā ma mua, me nā ʻōmaʻomaʻo momona e kū kiʻekiʻe ana i ke kua o ke awāwa. Ua ʻohi ʻo David lāua ʻo Emily i kā lāua hua maikaʻi loa i nā makahiki—ka kulina ikaika a olakino a me nā mea kanu olaola i hoʻāla i ka hauʻoli ma ka mākeke mahiʻai kūloko. Ua hoʻokokoke aku nā mahiʻai mai nā mahina ʻai kokoke iā lāua e aʻo i kā lāua mea huna.
"ʻO ke ʻano o ka wai! Pili ia i ka oxygen i loko o ka wai," wahi a Emily me ka haʻaheo. "Me kā mākou sensor oxygen hoʻoheheʻe optical, hiki iā mākou ke pane koke i nā loli. Ua kōkua ia iā mākou e mālama i kahi ʻōnaehana olaola."
I ka laha ʻana o ka lono ma ke awāwa ʻo Crestview, ua hoʻomaka ka poʻe mahiʻai e apo i ka ʻenehana. Ua loaʻa i ke kaiāulu kahi ʻōnaehana kākoʻo hou kahi i kaʻana like ai lākou i ka ʻikepili a me nā hana maikaʻi loa. Ua hana lākou i kahi pūnaewele kūhelu ʻole e kūkākūkā i ka maikaʻi o ka wai a me kona hopena hiki ʻole ke hōʻole ʻia i ke olakino o nā mea kanu. ʻAʻole lākou e hakakā wale ana i kā lākou mau hakakā; akā, he ʻāpana lākou o kahi neʻe nui i ka hoʻomau a me ke kūpaʻa.
He Wā e Hiki Mai Ana
I kekahi mau mahina ma hope mai, i ka huli ʻana o nā kau a me ka hoʻomākaukau ʻana o ka mahiʻai no ka hoʻoilo, ua noʻonoʻo ʻo David i ka mamao o kā lākou hele ʻana. ʻAʻole wale ka mea ʻike oxygen hoʻoheheʻe ʻia i hoʻololi i kā lākou hana mahiʻai akā ua hoʻokumu pū i nā pilina mau loa i loko o ko lākou kaiāulu. ʻOi aku lākou ma mua o ka mahiʻai i kēia manawa; he mau kahu mālama lākou o ke kaiapuni, i hoʻohiki ʻia e pale i ko lākou wai, nā mea kanu, a me ka ʻāina a lākou i aloha ai.
Me ka haʻaheo, ua ʻākoakoa ʻo David lāua ʻo Emily ma ka lihi o ka loko, e nānā ana i ka napoʻo ʻana o ka lā ma luna o nā wai olaola. Ua ola ka lewa me nā leo o ke kūlohelohe, a ua kū ikaika nā mea kanu ma nā mahina ʻai ma hope o lākou. Ua ʻike lākou ua lawe lākou i nā ʻanuʻu koʻikoʻi i kahi wā e hiki mai ana—kahi e alakaʻi ai ka wai olakino i nā mea kanu olakino, e hōʻoiaʻiʻo ana i ke ola lōʻihi o kā lākou mahiʻai no nā hanauna e hiki mai ana.
I ko lāua kū pū ʻana, ua minoʻaka ʻo Emily i kona makuakāne, "ʻO wai ka mea i ʻike e hiki i kahi mea ʻike liʻiliʻi ke hana i kahi ʻokoʻa nui?"
"I kekahi manawa, ʻo nā hoʻonā maʻalahi loa ka mana nui loa. Pono mākou e mākaukau e apo iā lākou," i pane aku ai ʻo Dāvida, e nānā ana i ka ʻāina e ulu nui ana me ka manaʻolana no ka wā e hiki mai ana.
No ka ʻike hou aku e pili ana i ka sensor maikaʻi o ka wai,
