I. Amahame Mpuzamahanga agenga amazi yo kunywa yujuje ibisabwa

Umutekano w'amazi yo kunywa ni inkingi y'ingenzi mu buzima bw'abantu, kandi umuryango mpuzamahanga ufite amabwiriza akaze kandi arambuye ku bipimo ngenderwaho by'amazi yo kunywa yujuje ibisabwa. Nk'ikigo mpuzamahanga mu by'ubuzima rusange, Umuryango Mpuzamahanga wita ku Buzima (OMS) washyizeho amahame ngenderwaho y'amazi yo kunywa afite akamaro kanini. Asobanura amazi meza yo kunywa nk'amazi, iyo anyowe ku gipimo cya litiro 2 ku munsi mu buzima bwose bushingiye ku myaka 70 y'ubuzima, nta ngaruka zikomeye ku buzima. Iyi nsobanuro kandi ikubiyemo amazi akoreshwa mu isuku ya buri munsi.

Ku bijyanye n'ibimenyetso byihariye, OMS ivuga ko amazi yo kunywa adakwiye kuba arimo udukoko dutera indwara, ari nabyo by'ingenzi mu gukumira indwara ziterwa n'amazi. Hagati aho, urugero rw'ibintu bya shimi n'ibikomoka kuri radiyo mu mazi bigomba kugenzurwa mu buryo budashyira mu kaga ubuzima bw'abantu. Imiterere y'amajwi nayo ni ingenzi: amazi agomba kuba afite isura nziza, ibara ryiza, impumuro nziza, n'uburyohe, kuko ibi ari byo bimenyetso by'ingenzi bituma abantu basuzuma niba amazi meza yemerwa. Byongeye kandi, amazi yo kunywa agomba kuba arimo imiti yica udukoko dutera indwara kugira ngo yica cyangwa ahagarike udukoko dutera indwara. Uburyo busanzwe bwo kwica udukoko burimo chlorine, chlorine, ozonation, na ultraviolet disinfecting.

Ibihugu bitandukanye n'uturere nabyo byashyizeho amahame yabyo bishingiye ku mabwiriza ya OMS, hamwe n'imiterere yabyo nyayo. Amahame ngenderwaho y'Ubushinwa ku Ireme ry'Amazi yo Kunywa (GB 5749-2022) ashyiraho ibisabwa bitanu by'ibanze ku buzima ku ireme ry'amazi, bihuye n'amahame ya OMS, mu gihe binonosora ibipimo bimwe na bimwe hakurikijwe ibikenewe mu ngo no mu buzima. Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) gifite kandi amahame ngenderwaho y'amazi yo kunywa, afite imipaka isobanutse ku bihumanya ikirere bitandukanye. Urugero, cyakomeje gushimangira kugenzura ibyuka bihumanya ikirere nk'ibintu bya per- na polyfluoroalkyl (PFAS). Amahame ngenderwaho y'Umuryango w'Ubumwe bw'u Burayi arakomeye kurushaho; urugero, gishyiraho umupaka wa nitrate kuri 3 mg/L, ugereranije n'amahame ngenderwaho ya 10 mg/L yashyizweho na OMS n'Ubushinwa.

II. Imbogamizi mu kugenzura umutekano w'amazi yo kunywa

(1) Ikwirakwizwa ry'umutungo ku isi ritaringaniye

Raporo za Loni zigaragaza ko abantu bagera kuri miliyari 2.1 ku isi yose baracyabura amazi meza yo kunywa, muri bo miliyoni 106 banywa amazi yo hejuru adasukuwe. Mu bihugu bikennye, abaturage bafite amahirwe akubye kabiri yo kubura amazi meza yo kunywa n'isukura ugereranyije n'abo mu bindi bihugu. Icyuho hagati y'imijyi n'icyaro nacyo kiracyahari, aho amazi meza n'isukura mu byaro biri inyuma cyane iyo mu mijyi. Mu byaro akenshi hakunze kubaho ibibazo nk'amazi adakora neza, ingano y'amazi idahagije, uburinzi buke bw'amazi, aho amazi adakora neza, ndetse n'imiyoboro y'amazi isaza cyane kandi ivamo amazi, ibyo byose bigatuma bigorana kwemeza ko amazi meza asukura neza.

(2) Ibibazo by'Ihumana Bikomeje Kwiyongera

Iterambere ryihuse ry’inganda n’umusaruro munini w’ubuhinzi byatumye umwanda w’amazi urushaho kuba ikibazo gikomeye. Gusohora amazi mabi mu nganda mu buryo butemewe n’amategeko binjiza ibintu byinshi bya shimi mu mazi. Ibi bintu biguma mu mazi igihe kirekire, byinshi ntibibora, kandi bishobora kwangiza umubiri w’umuntu mu buryo butaziguye. Ubunini bwinshi mu gihe gito bushobora gutera uburozi bukabije, mu gihe ubunini buke mu gihe kirekire bushobora gutera uburozi budakira. Ifumbire mvaruganda n’imiti yica udukoko bikoreshwa mu buhinzi byinjira mu mazi binyuze mu mazi y’imvura atemba, bigatera imyuka mibi n’umwanda. Byongeye kandi, bimwe mu bihumanya bivuka, nka "imiti ihoraho" nka PFAS, biragoye kwangirika mu bidukikije karemano, byirundanya mu bidukikije no mu mibiri y’abantu, kandi bigatera ibibazo bishya ku mutekano w’amazi yo kunywa.

(3) Ingaruka nshya ziterwa n'imihindagurikire y'ikirere

Imihindagurikire y’ikirere ku isi yatumye habaho imihindagurikire y’ikirere ikunze kugaragara nko amapfa, imvura nyinshi n’ubushyuhe bwinshi, bizana imbogamizi nshya ku mutekano w’amazi yo kunywa. Amapfa agabanya ingano y’amazi ndetse akanatuma amasoko y’amazi yumuka, bigatuma umuvuduko w’amazi uzamuka. Imvura nyinshi ishobora gutera imyuzure, ikajyana imyanda ku butaka mu mazi no kwangirika k’ubwiza bw’amazi. Hagati aho, imihindagurikire y’ikirere ishobora no guhungabanya uburinganire bw’ibidukikije mu miyoboro y’amazi, bigatera ibibazo nko kurabya cyane ibimera by’ibimera, bikongera kugira ingaruka ku mutekano w’amazi yo kunywa.

III. Uruhare rw'Igenzura ry'Ubuziranenge bw'Amazi mu Kugenzura Umutekano w'Amazi yo Kunywa

Gukurikirana ubuziranenge bw'amazi ni ingenzi mu kwemeza ko amazi yo kunywa afite umutekano, bigakurikirana ibikorwa byose kuva ku masoko y'amazi kugeza ku mavomero.

(1) Kugenzura isoko ry'inkomoko

Gukurikirana buri gihe ubwiza bw'amazi ku masoko y'amazi bishobora kumenya ku gihe niba amazi yanduye, ndetse n'ubwoko n'ingano y'umwanda. Urugero, kugenzura ubwiza bw'amazi yo mu migezi, ibiyaga, amazi yo munsi y'ubutaka, n'andi masoko bifasha gukurikirana impinduka mu bimenyetso nk'udukoko dutera indwara, ibintu bya chimique, n'ibintu bifite imirasire. Iyo ibimenyetso bidasanzwe bigaragaye, ingamba zishobora gufatwa vuba, nko gusuzuma aho amazi yanduye no gushimangira uburyo amazi aturuka, kugira ngo hamenyekane umutekano w'amazi yo kunywa ava aho amazi aturuka.

(2) Igenzura ry'ibikorwa

Mu gihe cyo gusukura amazi yo kunywa, kugenzura ubuziranenge bw'amazi byemeza ko inzira zo kuyasukura zikora neza. Mu kugereranya ubuziranenge bw'amazi mbere na nyuma yo kuyasukura, birashoboka kumenya niba inzira nko kuyasukura no kuyayungurura zageze ku musaruro witezwe, no guhindura ibipimo byo kuyasukura ku gihe kugira ngo hamenyekane ko amazi ava mu ruganda ahuye n'ibipimo ngenderwaho. Hagati aho, kugenzura ubuziranenge bw'amazi mu gihe cyo kuyatwara bishobora kugaragaza ibibazo nko kuva kw'imiyoboro n'umwanda wa kabiri mu gihe cyagenwe. Urugero, gukurikirana impinduka mu miyoboro isigaye ishobora gufasha kumenya niba hari umwanda wanduye mu miyoboro, kugira ngo gusana no kuyatunganya bikorwe vuba.

(3) Ingwate y'umuyoboro w'amazi urangiye

Ku ruhande rw'umukoresha,kugenzura ubuziranenge bw'amaziBituma abaturage basobanukirwa ubwiza bw'amazi yo kunywa mu ngo zabo. Kuba haravutse ibikoresho byo gupima ubuziranenge bw'amazi bifasha abaturage gupima bimwe mu bimenyetso by'amazi yo kunywa bonyine, nko gushonga kw'amazi, pH, n'imiti yica udukoko isigaye. Ibi ntibyongerera gusa icyizere abaturage bafite mu bijyanye n'umutekano w'amazi yo kunywa, ahubwo binabafasha kubona ibibazo no kubimenyesha inzego zibishinzwe ku gihe, bigatuma habaho umwuka mwiza wo kugenzura umutekano w'amazi yo kunywa mu baturage bose.

Byongeye kandi, amakuru ajyanye no kugenzura ubuziranenge bw'amazi atanga ishingiro ry'ingenzi mu gushyiraho politiki n'ubushakashatsi bwa siyansi. Gusesengura amakuru menshi ajyanye no kugenzura bifasha gusobanukirwa imiterere rusange n'iterambere ry'umutekano w'amazi yo kunywa, bishyigikira ishyirwaho ry'amahame ya siyansi kandi yumvikana y'amazi yo kunywa na politiki yo kuyacunga. Binafasha abashakashatsi gukora ubushakashatsi bwimbitse ku miterere y'amazi yanduye n'ikoranabuhanga ryo kuyatunganya, bikomeza kunoza urwego rw'umutekano w'amazi yo kunywa.

Andika ubutumwa bwawe hano hanyuma ubwoherereze
