Ubushakashatsi bushya bufatanije n’abashakashatsi ba Virginia Tech bugaragaza ibibazo bijyanye n’ibicuruzwa bimwe na bimwe bikozwe mu muringa muri sisitemu yo gukoresha amazi bishobora gutera amazi menshi mu mazi, ndetse no mu nyubako nshya - kandi byerekana ko ibibazo nk'ibi bishobora kutamenyekana.

Isasu nicyuma kiremereye gishobora kwangiza imitsi niterambere ryubwonko, kandi ni bibi cyane kubagore batwite, impinja nabana.

Ubushakashatsi bwasohotse mu kinyamakuru cyo mu Gushyingo 2010 cy’ikinyamakuru cy’Abanyamerika gishinzwe imirimo y’amazi, ni ibisubizo by’ubushakashatsi bwakozwe hagati ya kaminuza ya Carolina y'Amajyaruguru kuri Chapel Hill na Virginia Tech.

Ubushakashatsi bwakozwe na Carolyn Elfland, umuyobozi wungirije wungirije ushinzwe serivisi z’ikigo kuri Chapel Hill, hamwe na Marc Edwards, umwarimu wa Charles Lunsford ushinzwe ubwubatsi, na Paolo Scardina, umwungirije wungirije ushinzwe imyitozo, haba mu ishami rya Virginia Tech Charles E. Via Department. y'ubwubatsi bwa gisivili n'ibidukikije.

Ubufatanye bwatangiye mu ntangiriro za 2007, ubwo Chapel Hill yavumburaga amazi menshi mu nyubako nshya agasaba Virginia Tech gufasha mu gusuzuma no gukemura ikibazo. Iri tsinda ryateguye porotokoro isukuye, igamije kureba niba mbere y’inyubako zikorwa, robine nshya n’amasoko y’amazi byujuje icyerekezo cy’ikigo gishinzwe kurengera ibidukikije n’itegeko ry’umuringa bitarenze mikoro 15 ya litiro y'amazi, cyangwa ibice 15 kuri miliyari.

Abashakashatsi bemeje kandi ko guhindura ibikoresho byo gukoresha amazi byujuje ibisabwa bisabwa n'amategeko ya Californiya, bikaba bitoroshye kuruta amategeko ya leta, bitazakemura ikibazo.

Hagati mu mwaka wa 2008, ikibazo gikomeye kidasanzwe cyavutse n'amasoko abiri yo kunywa mu nyubako nini ya laboratoire, imwe muri yo ikaba yari ifite urwego rurenga ibice 300 kuri miliyari. Kugerageza gusubiramo inshuro nyinshi mumezi menshi no gukoresha ingamba zisanzwe zo gukosora ntibyatsinzwe.

Ikibazo amaherezo cyashakishijwe isoko muri sisitemu yo kuvoma inyubako hejuru yisoko y'amazi. Impamvu yari ubwoko bwihariye bwumupira wumupira kandi ikibazo cyarazimiye iyo valve yakuweho. Nyuma yaho wasangaga zifite 18% ziyobowe nuburemere hejuru yimbere ihuza amazi yo kunywa. Nyuma igeragezwa ryerekanye ko indiba zizajya ziyobora kurwego rwo hejuru ya EPA mumezi.

Iyi mibande yafatwaga nk'amategeko, kubera ko impuzandengo yazo muri rusange yari munsi ya 8 ku ijana byemewe n'amategeko, kandi byashyizwe ku rutonde ko byujuje ubuziranenge bwa National Sanitation Foundation International, uruganda rukora ibikoresho byo gukoresha amazi mu rwego rw’igihugu. Mugihe haribindi byagaragaye neza mubikoresho byumuringa nka robine nisoko yamazi kumpera yumurongo wamazi utemba biganisha kumazi, iki kibazo ni ubwambere igikoresho kizamuka mumurongo w'amazi byagaragaye ko kiva murwego rushimishije rwa biganisha ku mazi yo kunywa yageze kuri robine.

Yagenzuye ubushakashatsi bwakozwe na Edwards, bwagaragaje impungenge zijyanye no gupima ubuziranenge bwakoreshejwe mu kwemeza ibikoresho bikozwe mu muringa kugira ngo bikoreshwe muri sisitemu yo gukoresha amazi. Mu gusubiza icyo gikorwa, Ikigo cy’igihugu gishinzwe isuku cyashyize mu bikorwa ingingo zikomeye, zizatangira gukurikizwa mu 2012. Icyakora, aya mahame akomeye agaragaza amahame ya Californiya, kandi uburambe bw’itsinda ry’ubushakashatsi bwa Chapel Hill-Virginia Tech bwerekana ko bishoboka ko na bo bakiriho. abanditsi bavuze.

Edwards, yiswe Mugenzi wa MacArthur mu 2007, yavuze ko uru rubanza rwagaragaje impungenge zishingiye ku bikoresho byo mu rwego rwo hejuru mu bikoresho bimwe na bimwe bikozwe mu muringa, ndetse hakenewe uburyo bwo gukumira ishyirwaho ry’ibicuruzwa bifite inenge mu iyubakwa rishya.

Ati: "Urwego rw'isasu rwagaragaye muri UNC rwarenze izwiho gutera umuvuduko mwinshi w'amaraso ku bana, nk'uko byashyizweho n'ikigo gishinzwe kurwanya indwara, ndetse n'inzego zitera uburozi bukabije bwa sisitemu yashyizweho na komisiyo ishinzwe umutekano ku bicuruzwa." "Igishimishije ni uko inzira za UNC zafashe iki kibazo mbere yuko umuntu uwo ari we wese ashobora guhura n’amazi menshi mu mazi, ariko mu bindi bihe byinshi ikibazo nticyamenyekana. Kuba hari ibicuruzwa bifite inenge, byashyizwe ku rutonde nk’umutekano, byashoboraga gushyirwa mu mashuri no ku bana. bigo no kugirira nabi abana birababaje cyane"

Elfland ya Chapel Hill yavuze ko isukari nyinshi mu mazi yagaragaye bwa mbere nk'ikibazo mu gihe cy'ingoma y'Abaroma, kandi ko kugurisha amasasu hamwe n'imiyoboro y'isasu bitemewe mu myaka mirongo.

Ati: "Abantu bafite uburenganzira bwo kwitega ko amazi yo kunywa mu nyubako nshya atazanduzwa n’isasu, kandi ba nyir'inyubako ntibagomba gushyiramo ingufu n’amafaranga UNC ikora kugira ngo ibyo byifuzo bigerweho". iki ni ikibazo gikomeye cyo kunanirwa kugenzura."

Ubushakashatsi bwikipe ya Chapel Hill-Virginia Tech bwerekanye ko igiciro kinini cyibikoresho "biganisha ku buntu" byarangira bizigamye amafaranga. Elfland yavuze ko Chapel Hill isanzwe mbere yo gutwarwa na protocole yongeraho $ 49 kugeza $ 91, cyangwa hagati ya 24% kugeza 45%, kubiciro bya buri kintu. Igiciro cyose cyo gushakisha no gusimbuza valve ifite ibibazo muri sisitemu yo gukoresha amazi yari $ 30 000, niba umushahara wabantu bose bakoze kuri kiriya kibazo urimo. Imyanda yabanje kugura amadorari 20 buri umwe.

Mu ntangiriro z'uku kwezi, umushinga w'itegeko rya Sena yo muri Amerika wo kugabanya umubare wemewe w'isasu mu bikoresho byo kuvoma umuringa uva kuri 8 ku ijana ukagera ku kigereranyo cya 0.25 ku ijana byashyizweho na Senateri Barbara Boxer (D-Calif,), umuyobozi wa Sena ishinzwe ibidukikije na rubanda. Komite ishinzwe imirimo. Mu magambo ye, Boxer yagize ati: "Icy'ingenzi ni uko mu mazi yacu yo kunywa nta rwego rufite umutekano - icyuma kiremereye gifite ubumara -"
