Ucwaningo luye lwaqinisekisa ukuthi amapayipi ethu kasimende agugile aguguleka ngokushesha kunaphesheya kwezilwandle, nokuthi imicu ye-asbestos ingena emanzini - kodwa hhayi emazingeni ayingozi okwamanje.
Abacwaningi base-University of Otago's School of Geography bathole “ubufakazi obuningi” bemicu ye-asbestos emasampula amanzi okuphuza avela ezindaweni ezingama-35 ezizungeze i-Christchurch futhi bathi lokhu kuzophindwaphindwa emanzini ezweni lonke.
Njengamanje iNew Zealand inamapayipi angu-9000km amapayipi e-asbestos azoshintshwa ngenani elilinganiselwa ku-$2.2 billion, kusho ucwaningo.
Usimende we-asbestos wawusetshenziswa emapayipini amanzi emhlabeni wonke kusukela ngeminyaka yawo-1930 kuya kowe-1980, lapho kwabonakala ukuthi ayengakhulula imicu ye-asbestos emanzini lapho yonakele.

Ababhali bocwaningo bathi inqwaba yamapayipi manje isidlulile kakhulu empilweni yawo futhi isengcupheni yokwehluleka.
Omunye umbhali uDkt Sarah Mager uthe ezingxenyeni eziningi zaseNew Zealand, amanzi anezinga eliphansi le-calcium ne-magnesium, okuvumela amapayipi usimende we-asbestos ukuba anciphe ngenani eliphezulu futhi akhiphe imicu ye-asbestos eyengeziwe.
“Izinga lalokhu kugqwala lishesha kakhulu, ngakho amapayipi abola ngaphakathi ngokushesha kunezibonelo zakwamanye amazwe.”
Ocwaningweni lwase-Christchurch, kutholwe imicu ye-asbestos kumasampuli angu-19 wezindawo ezingu-20 zamapayipi omlilo kanye namasampula amathathu kwayi-16 ompompi wasendlini.
Lelo nani alizange lidlule amazinga aphephile ngaphansi kwemihlahlandlela yase-US - okuwukuphela kwezwe elinemihlahlandlela ye-asbestos emanzini okuphuza.
Ilabhorethri yochwepheshe yamazwe ngamazwe e-US ihlaziye amasampula amanzi avela e-Christchurch kulokho abacwaningi abathi kungokokuqala ngqa ukuthi ihlole kahle ukuguguleka kwamanzi ngenxa yokuguga kwamapayipi e-asbestos aseNew Zealand.
UMkhandlu Wedolobha LaseChristchurch wawuke wathatha ama-hydrants angu-17 e-asbestos fibers ngo-2017 futhi wawathola kwelinye.Nokho, ababhali bocwaningo bathi izindlela zokuhlaziya ezisetshenzisiwe zazinganele.
Nakuba izingozi ze-asbestos esemoyeni njenge-carcinogen zaziwa kahle, imiphumela yezempilo yokuyingenisa ayikaqedwa futhi awukho umkhawulo olawulayo wokukhawulela imicu ye-asbestos emanzini okuphuza eNew Zealand.
Lo mbiko, oshicilelwe yi-International Water Association's Journal of Water Supply, ucaphuna ucwaningo lwakamuva olubonisa ukuhlobana phakathi kwe-asbestos emunyisiwe kanye nokusabalala komdlavuza wesisu nowesisu, kanye nokuba khona kwe-asbestos ezicutshini zamathumbu. ubufakazi ku.
I-World Health Organization, imihlahlandlela yamanje yokuphatha ikhwalithi yamanzi aphuzwayo yaseNew Zealand kanye neziqondiso zamanzi okuphuza zase-Australia zithi akukho datha eyanele emhlabeni wonke ukuze kutholakale isixhumanisi sezempilo se-asbestos emanzini okuphuza.
Noma kunjalo, ababhali abakanye nabo kulolu cwaningo bathi imiphumela ye-asbestos emanzini okuphuza ayizange ihlolwe ngokwanele.
"Isixhumanisi se-epidemiological phakathi kwemicu ye-asbestos emanzini okuphuza kanye nesigameko somdlavuza singatholakala kuphela uma idatha ye-asbestos fibers ikhona: le datha ayiqoqwa njalo."
Amapayipi kasimende e-asbestos ayaziwa ukuthi antekenteke ekuzamazameni komhlaba ngoba antekenteke futhi alimala kalula.
Ucwaningo luthole ukugxiliswa okuphezulu kakhulu kwemicu ye-asbestos kwatholakala ezindaweni ezisempumalanga yedolobha, lapho amapayipi ayendlalwe khona ngokugcwaliswa kwenhlabathi yendabuko esikhundleni setshe.
U-Tim Drennan, oyibamba lenhloko yamanzi amathathu eMkhandlwini weDolobha lase-Christchurch, uthe kube nokwenyuka “kwezinhlelo zokuvuselela kabusha eziqhubekayo” kusukela ngeminyaka yawo-1990 futhi idolobha linamaphesenti angama-21 kuphela amanzi alo. Amapayipi angamapayipi kasimende we-asbestos.
"Kubalulekile ukugcizelela ukuthi amapayipi usimende we-asbestos kunethiwekhi yethu yamanzi awabangeli izinkinga zempilo ngokushesha."
UDrennan uthe umkhandlu uqhuba “inqubo yokubeka eqhulwini encike engcupheni” ebheka ukuthi kungakanani ukwehluleka okuwuthintayo umphakathi uwonke.
UDrennan uthe iningi lokuvuselelwa kwamapayipi amanzi umkhandlu okuhlelwe ukuthi eminyakeni engu-27 ezayo kuzoba ngamapayipi kasimende we-asbestos.
Ngenxa yesampula elinganiselwe, ababhali abakwazanga ukunquma ukuthi umonakalo wokuzamazama komhlaba kanye nokucwiliswa kwamanzi e-Christchurch kwakusho ukuthi amanzi edolobha anezinga eliphezulu lemicu ye-asbestos kunezinye izindawo.
Kodwa-ke, batusa ukuthi yonke imikhandlu “iqaphe ukuhlinzekwa kwamanzi amisiwe emicu ye-asbestos, ikakhulukazi njengoba la mapayipi efinyelela ekupheleni kokusebenza kwawo, ukuze abone ukuguga kwamapayipi futhi abeke eqhulwini ukushintshwa kwezingxenye zamapayipi”.
"Lokhu kuyinkinga yezwe lonke ngoba amapayipi kasimende-asbestos aneminyaka efanayo futhi afakiwe - ngakho-ke kunengqondo ukucabanga ukuthi yonke iNew Zealand izoba nezinga elifanayo lokukhishwa kwe-asbestos," kusho omunye umbhali uMichael Nopic.
"Iqiniso liwukuthi ingaphansi komhlaba, ifihliwe, futhi asicabangi ngayo kuze kube yilapho ingasebenzi."
