Ukubeka esweni umgangatho wamanzi ngokufanelekileyo yinxalenye ebalulekileyo yezicwangciso zempilo yoluntu kwihlabathi liphela. Izifo ezibangelwa ngamanzi zihlala zingunobangela ophambili wokufa phakathi kwabantwana abasakhulayo, zibulala phantse abantu abangama-3,800 yonke imihla.
1. Uninzi lwaba bantu bafayo lunxulunyaniswa neentsholongwane emanzini, kodwa iWorld Health Organization (WHO) ikwaphawule ukuba ungcoliseko oluyingozi lwamanzi okusela, ingakumbi i-lead kunye ne-arsenic, yenye yezizathu zeengxaki zempilo zehlabathi.
2. Ukujonga umgangatho wamanzi kuvelisa imingeni emininzi. Ngokubanzi, ukucaca komthombo wamanzi kuthathwa njengophawu oluhle lokucoceka kwawo, kwaye kukho iimvavanyo ezikhethekileyo zokuwuvavanya (umz., uvavanyo lweSage Plate). Nangona kunjalo, ukulinganisa nje ukucaca kwamanzi akulona uvavanyo olupheleleyo lomgangatho wamanzi, kwaye uninzi lwezinto ezingcolisayo zeekhemikhali okanye zebhayoloji zinokubakho ngaphandle kokubangela utshintsho olubonakalayo lombala.
Lilonke, nangona kucacile ukuba iindlela ezahlukeneyo zokulinganisa nokuhlaziya kufuneka zisetyenziswe ukudala iiprofayili zomgangatho wamanzi ezinokuthenjwa, akukho mvumelwano icacileyo kuzo zonke iiparameter kunye nezinto ekufuneka ziqwalaselwe.
3. Izinzwa zomgangatho wamanzi okwangoku zisetyenziswa kakhulu kwiindlela zokuvavanya umgangatho wamanzi.
4. Ukulinganisa ngokuzenzekelayo kubalulekile kwiindlela ezininzi zokusebenzisa umgangatho wamanzi. Ukulinganisa ngokuzenzekelayo rhoqo yindlela engabizi kakhulu yokubonelela ngedatha yokubeka esweni enika ulwazi malunga nokuba kukho naziphi na iindlela okanye unxibelelwano neziganeko ezithile eziyingozi kumgangatho wamanzi. Kwiikhemikhali ezininzi ezingcolisayo, kuluncedo ukudibanisa iindlela zokulinganisa ukuqinisekisa ukuba kukho iintlobo ezithile. I-Arsenic, umzekelo, yikhemikhali engcolisayo ekhoyo kwiindawo ezininzi zehlabathi, kwaye ungcoliseko lwe-arsenic emanzini okusela yingxaki echaphazela izigidi zabantu.
