Ngabe amanzi akho ompompi aphephile? Ingabe udinga isisefo samanzi? Ukuze uthole izimpendulo, UBUME uphendukele kuDkt. Kathleen McCarty, uprofesa ongumsizi eSikoleni Sezempilo Somphakathi saseYale University, oyingcweti emanzini okuphuza nemiphumela yezempilo yabantu kanye nomeluleki kwi-U.S. EPA mayelana nokungcola kwezempilo kwezingane namanzi okuphuza.

Umbuzo: Ingabe ukhona umehluko phakathi kwamanzi kampompi namanzi asebhodleleni?

A: Kokubili amanzi asemabhodleleni nawompompi aphephile ukusetshenziswa. Amanzi ompompi alawulwa (yi-EPA) ukuthi aphephe lapho evela empompini, futhi amanzi asemabhodleleni alawulwa (yi-FDA) ukuze aphephe lapho evalelwa emabhodleleni. Izindinganiso zokuphepha kwamanzi kampompi zicabangela izinqubo phakathi nesikhathi lapho amanzi ephuma endaweni yokuhlanza futhi efinyelela kumthengi ekhaya. Ngamanye amazwi, amanzi kampompi alawulwa ukuze aphephe ngendawo aphuma kuyo empompini. Amanzi asemabhodleleni alawulwa ukuhlangabezana namazinga okuphepha lapho efakwa ebhodleleni futhi evaliwe. Ayikho imithethonqubo edinga ukuthi imboni yamanzi asemabhodleleni ivivinye ikhwalithi yamanzi ngemuva kokuthi ifakiwe, kanti iBPA namanye amakhemikhali asetshenziswe kupulasitiki atholakele kubantu ngemuva kokusetshenziswa kwamanzi asemabhodleleni.

Umbuzo: Yiziphi ezinye izindaba okufanele sicabange ngazo nganoma yiluphi uhlobo lwamanzi?

A: Amanzi ompompi abiza kancane kakhulu kunamanzi asebhodleleni, futhi alashwa nge-fluoride ukuvikela amazinyo omuntu komasipala abaningi. Kodwa-ke, abanye abantu bakhetha ukunambitheka kwamanzi asemabhodleleni ukuze bawathinte ngenxa yokunambitheka kwe-chlorine noma iphunga, futhi ngamanzi ompompi kunengozi encane yokuchithwa ngokweqile kanye nokukhishwa kwamagciwane ngemikhiqizo eyenziwe enqubeni ye-chlorination. Futhi kukhona umthelela wezemvelo wamabhodlela epulasitiki - ekukhiqizeni kwawo nangemva kokuba esetshenzisiwe.

Q: Ungasincoma isihlungi samanzi?

A: Ngingancoma ukuhlungwa kwabantu abangakuthandi ukunambitheka kwamanzi kampompi, ngokuqaphela okuthile mayelana nokunakekelwa.Izihlungi ezinjengeBrita izihlungi zekhabhoni, ezibhekele ukumunca izinhlayiya emanzini. Izihlungi ze-Brita zizonciphisa amazinga ezinye izinsimbi futhi zingasetshenziswa ukuthuthukisa ukunambitheka kwamanzi kampompi noma ukunciphisa iphunga (kusuka ku-chlorination). Enye indlela ukugcina amanzi embizeni; ukunambitheka kwe-chlorine kuzonyamalala. Isexwayiso esisodwa ngesihlungi se-Brita ukuthi ukungasigcini isihlungi simanzi futhi imbiza igcwaliswe ezingeni elifanele kungabangela amagciwane ukuthi akhule kusihlungi. Landela imihlahlandlela ukushintsha isihlungi; ngaphandle kwalokho, unganyusa amazinga webhaktheriya emanzini ngaphezu kwamazinga aphephile.

Q: Yikuphi okunye esingaqinisekisa noma silawule ikhwalithi yamanzi ethu?

A: Uma uhlala ekhaya elidala lapho kungahle kube khona i-solder yomthofu, sebenzisa amanzi akho ompompi umzuzu noma ngaphezulu ngaphambi kokusebenzisa amanzi. Futhi sebenzisa amanzi abandayo kunamanzi afudumele ukubilisa noma ukuphuza. Ezindaweni lapho kusetshenziswa khona amanzi kahle, ngincoma ukuthi kuhlolwe njalo amanzi okuphuza. Iminyango yezempilo yasendaweni neyesifunda ingakusiza ekunqumeni ukuthi yikuphi ukuhlolwa okufanele kuqedwe, ngokusekelwe ezintweni zendawo. Omasipala bathumela umbiko waminyaka yonke wezinga lamanzi okuphuza emakhaya kanye ngonyaka futhi kufanele ufunde lo mbhalo. I-EPA idinga le mibiko, echaza ukuphepha kwamanzi ompompi, minyaka yonke. Uma ukhathazekile ngokuvezwa kwe-BPA namanzi okuphuza, ngincoma ukuthi ungaphinde usebenzise amabhodlela, noma kungenjalo utshale imali kumabhodlela engilazi noma amanye amabhodlela amanzi angenayo i-BPA. Ngokwami, ngiphuza njalo amanzi asemabhodleleni namanzi ompompi futhi ngicabanga zombili izinqumo ezinempilo.
