Ngaba amanzi akho empompo akhuselekile? Ngaba ufuna isihluzo samanzi? Ngeempendulo, UBUME waphendukela kuDkt. Kathleen McCarty , uprofesa oncedisayo kwiYunivesithi yaseYale yeSikolo seMpilo yoLuntu, ngubani oyingcali emanzini okusela kunye nemiphumo yempilo yabantu kunye nomcebisi kwi-EPA yase-US kwimpilo yabantwana kunye nokungcola kwamanzi okusela.

Umbuzo: Ngaba kukho umahluko phakathi kwempompo kunye namanzi asebhotileni?

A: Amanzi asebhotileni nawetephu akhuselekile ukuba angasetyenziswa. Amanzi empompo alawulwa (yi-EPA) ukuba akhuseleke xa evela kwimpompo, kwaye amanzi asebhotileni alawulwa (yi-FDA) ukuba akhuseleke xa ebhotile. Imigangatho yokhuseleko lwamanzi etephu ithathela ingqalelo iinkqubo phakathi kwaxa amanzi ephuma kwindawo yokucoca aze afikelele kumsebenzisi wekhaya. Ngamanye amagama, amanzi etepu alawulwa ngokhuseleko kwindawo apho ashiya khona impompo. Amanzi asebhotileni alawulwa ukuze ahlangane nemigangatho yokhuseleko xa efakwe ezibhotileni zitywinwe. Akukho mithetho ifuna ukuba ishishini lamanzi eebhotile livavanye umgangatho wamanzi emva kokuba lifakwe ebhotileni, kwaye i-BPA kunye nezinye iikhompawundi ezisetyenziswe kwiiplastikhi ziye zafunyanwa ebantwini emva kokusetyenziswa kwamanzi asebhotileni.

Q: Yeyiphi eminye imiba ekufanele ukuba siyicinga ngohlobo lwamanzi?

A: Amanzi empompo abiza kakhulu kunamanzi asebhotileni, kwaye anyangwa nge-fluoride ukukhusela amazinyo koomasipala abaninzi. Nangona kunjalo, abanye abantu bakhetha incasa yamanzi asebhotileni ukutephu ngenxa yencasa yeklorini okanye ivumba, kwaye ngamanzi etephu kukho umngcipheko omncinci wokugqithiswa kwe-fluorination kunye ne-disinfection by-products ezenziwe kwinkqubo ye-chlorination. Kwaye kukho ifuthe lokusingqongileyo kwiibhotile zeplastiki-kwimveliso yazo nasemva kokuba zisetyenzisiwe.

Umbuzo: Ungacebisa isihluzo samanzi?

A: Ndingacebisa ukuhluza abantu abangayithandiyo incasa yamanzi etephu, ngononophelo oluthile malunga nolondolozo.Iifilitha ezinje ngeBrita zizihluzo zekhabhoni, ezinoxanduva lokufunxa amasuntswana emanzini. Iifilitha zeBrita ziya kunciphisa amanqanaba ezinye izinyithi kwaye zinokusetyenziselwa ukuphucula incasa yamanzi etephu okanye ukunciphisa ivumba (ukusuka kwiklorini). Enye inketho kukugcina amanzi kwi-pitcher; incasa yeklorini iya kunyamalala. Isilumkiso esinye ngesihluzi seBrita kukuba ukungagcini isihluzo kumanzi kwaye ingqayi izaliswe kwinqanaba elifanelekileyo kunokubangela ukuba iibacteria zikhule kwifilitha. Landela izikhokelo ukutshintsha icebo lokucoca ulwelo; ngaphandle koko, unokwandisa amanqanaba ebhaktheriya emanzini ngaphaya kwamanqanaba akhuselekileyo.

Umbuzo: Yiyiphi enye indlela esinokuqinisekisa ngayo okanye silawule umgangatho wamanzi ethu?

A: Ukuba uhlala kwikhaya elidala apho kunokubakho i-solder ekhokelayo, sebenzisa amanzi akho empompo umzuzu okanye njalo ngaphambi kokusebenzisa amanzi. Kwakhona sebenzisa amanzi abandayo kunamanzi ashushu xa uwabilisa okanye uwasele. Kwiindawo apho kusetyenziswa khona amanzi kakuhle, ndingacebisa rhoqo ukuba kuvavanywe amanzi okusela. Amasebe ezempilo asekuhlaleni nawesizwe anokukunceda ekumiseleni ukuba loluphi uvavanyo ekufuneka ulugqibile, ngokusekwe kwimiba yendawo. Oomasipala bathumela ingxelo yonyaka yomgangatho wamanzi okusela kumakhaya kanye ngonyaka kwaye kufanelekile ukufunda olu xwebhu. I-EPA ifuna ezi ngxelo, ezichaza ukhuseleko lwamanzi aphuma kwiimpompo, ngonyaka. Ukuba unexhala malunga nokuvezwa kwe-BPA kunye namanzi okusela, ndingacebisa ukuba ungaphindi uzisebenzise iibhotile, okanye utyale imali kwiibhotile zeglasi okanye ezinye iibhotile zamanzi ezingenazo i-BPA. Ngokwam, ndisela zombini iibhotile kunye namanzi empompo rhoqo kwaye ndiqwalasele zombini ukhetho olusempilweni.
