Isikhungo Sokucwaninga Ngezokudla sase-Iowa State University simemezele inhloso yaso yokuxhasa inethiwekhi yezinzwa zekhwalithi yamanzi ukuqapha ukungcoliswa kwamanzi emifuleni nasemifuleni yase-Iowa, naphezu kwemizamo yesishayamthetho yokuvikela inethiwekhi yezinzwa.
Lezi yizindaba ezinhle kubantu base-Iowa abakhathalela ikhwalithi yamanzi futhi abakholelwa ukuthi badinga idatha yokuhlola imizamo kahulumeni yokunciphisa ama-nitrate ne-phosphorus angena emifuleni yamanzi. I-Center for Nutrition Research kanye nomqondisi wayo, uMatt Helmers, bafanelwe udumo ngokungavumeli ezombusazwe ukuthi zibe nomthelela othusayo ocwaningweni lwekhwalithi yamanzi.
“Uhlelo Lolwazi Lwekhwalithi Yamanzi lwase-Iowa luyithuluzi elibalulekile lokuqapha ikhwalithi yamanzi esifundazweni kanye nokulandelela ukusebenza kahle kwamasu okunciphisa izakhamzimba ase-Iowa,” kusho uHelmers ku-imeyili ayithumele ku-Erin Jordan we-The Gazette.
Ivoti leSishayamthetho lokuvikela inethiwekhi laliwumdlalo wezepolitiki ongacabangi kahle. Lo mzamo uholwa yiSen. Ryan Dan Zumbach wesifundazwe, umkhwenyana wakhe ongumnikazi wendawo yokudla enamakhanda angu-11,600 endaweni yamanzi aseBloody Run Creek enyakatho-mpumalanga ye-Iowa. Enye yezinzwa okukhulunywa ngazo yayitholakala endaweni yokudla eBloody Run Creek, umfudlana wezinhlanzi oqokwe njengomzimba wamanzi oqokiwe yi-Iowa Department of Natural Resources.
Ukukhipha imali kuma-sensor kumelela isinyathelo esisobala samaRiphabhulikhi alawula iSishayamthetho sokulawula ulwazi mayelana nenqubekela phambili yokuhlanza amanzi angcolile e-Iowa. Idatha yama-sensor ikhombisa njalo ukuthi indlela yase-Iowa yokuzithandela ngokuphelele yokufeza imigomo echazwe isu lokunciphisa izakhamzimba lesifundazwe ayizange iholele entuthukweni enkulu.
Kodwa-ke, ngisho noma i-Iowa State izibophezele, uxhaso locwaningo olusebenzisa idatha yezinzwa eNyuvesi yase-Iowa luzoncipha. I-UI ithole u-$375,000 kwi-Nutrition Research Center ukuze ihlaziye idatha yezinzwa futhi ilindele ukuthi lelo nani likhuphuke lifike ku-$500,000 ngonyaka wesabelomali olandelayo. Esikhundleni salokho, ngokubamba iqhaza, i-UI izothola u-$295,000 ngonyaka ozayo kanye no-$250,000 ngonyaka olandelayo.
Ngakho-ke, naphezu kokuzibophezela okuhle kwe-Iowa, izishayamthetho zamaRiphabhulikhi ziphumelele ekunciphiseni uxhaso lwezimali zocwaningo. I-Iowa ilahlekelwe. Uhlelo lwezinzwa luphethwe ngabantu base-Iowa, idatha eqoqwe iwulwazi lomphakathi, futhi okutholakele kocwaningo kunikeza isithombe esicacile sokuthi intuthuko encane kangakanani enenjongo eyenziwe ekuhlanzeni amanzi. Lolu daba lubaluleke kakhulu ukuvumela izishayamthetho ukuthi zigcine abantu base-Iowa bengenalwazi ngenxa yobudlelwano babo nezintshisekelo ezinkulu zezolimo.
Singahlinzeka ngezinhlobo ezahlukene zezinzwa zekhwalithi yamanzi njenge-ammonium nitrite, ezingenziwa ngokwezifiso, wamukelekile ukubonisana nathi.
