Vanhu vazhinji vanofarira kunaka nekuchengetedzeka kwemvura yekunwa. Sezvo nzizi nemadziva zvichisvibiswa nyore nyore netsvina yeindasitiri uye kuyerera kunobva munzvimbo dzokurima, mvura yepasi ndiyo manyuko makuru emvura yokunwa yemhando yepamusoro. Zvisinei, mvura yakadaro haisati yakachengeteka nguva dzose. Matsime mazhinji, manyuko emvura yokunwa, akashatiswawo. Nhasi, kusvibiswa kwemvura kunoonekwa seimwe yenjodzi huru kune hutano. Izvo zvinosvibisa zvinowanzoitika mumvura zvinogadzirwa kubva mukugadzira mvura neklorini. Zvigadzirwa izvi zvinowedzera njodzi yegomarara redundiro necolon. Vakadzi vane pamuviri vanodya zvakawanda zvezvigadzirwa izvi vari panjodzi yakawedzerwa yekubva pamuviri. Mvura yekunwa inogona kunge iine nitrate. Nitrate sosi mumvura yepasi (kusanganisira matsime epachivande) anowanzo marara ekurima, fetereza yemakemikari uye mupfudze kubva kunzvimbo dzekudyisa. Mumuviri wemunhu, nitrate inogona kushandurwa kuita nitrosamines, carcinogens. Mvura inosangana nepombi dzakasakara uye solder yelead pamajoini epombi inozadzwa nemutobvu, kunyanya kana ichidziya, ine oxidized kana kupfava. Vana vane mutobvu weropa wakakwira vanogona kusangana nezvinetso zvakadai sokukura kwakaoma, kuremara kudzidza, zvinetso zvetsika, uye kupererwa neropa. Kuratidzwa kune mutobvu kunotungamirirawo kune ngozi yekuwedzera yezvirwere zvekubereka. Mvura yakasvibiswa yakazarawo nezvirwere zvakadai se cryptosporidiosis. Zviratidzo zvaro kusvotwa, manyoka, uye mamiriro akaita sefuruu. Zviratidzo izvi zvinoramba zviripo kwemazuva manomwe kusvika gumi. Cryptosporidium parvum, protozoan inokonzera kupararira kwekriptosporidiosis, inowanzovapo mumadhamu nenzizi dzakasvibiswa netsvina kana marara emhuka. Ichi chipenyu chine kupikisa kwakanyanya kune chlorine uye mamwe majekiseni. Inogona kukonzera chirwere kunyangwe ikapinda mumuviri wemunhu muhuwandu husina basa. Mvura inofashaira ndiyo inonyanya kushanda nzira yekumisa Cryptosporidium parvum. Mvura yepombi inogona kucheneswa kubva mairi nekuda kwekudzosera osmosis kana kushandisa yakakosha sefa. Kunetseka nezvemishonga yezvipembenene, lead, ne-zvigadzirwa zvemvura chlorination, maindasitiri zvinonyungudutsa, nitrate, polychlorinated biphenyls nezvimwe zvinosvibisa mvura zvakakonzera kuti vatengi vazhinji vade mvura yemubhodhoro, vachifunga kuti ine hutano, yakachena uye yakachengeteka. Mvura yemubhodhoro inowanikwa nenzira dzakasiyana.
Mvura yechitubu, iyo inonyanya kutengeswa mumabhodhoro, imvura inobva pasi pevhu. Zvinotendwa kuti zvitubu zvakadaro hazvisi pasi pekusvibiswa, kunyangwe izvi zvisina chokwadi. Imwe nzvimbo yemvura yekunwa imvura yemupombi, uye inowanzoiswa mishonga inouraya utachiona kana kusefa isati yaiswa mubhodhoro. Kazhinji, mvura yakacheneswa inonatswa kana kuiswa kune reverse osmosis kana maitiro akafanana. Asi chikonzero chikuru chekuzivikanwa kwemvura yemubhodhoro ndiko kuravira kwayo, kwete kuchena. Mvura yemubhodhoro inoiswa disinfected ne ozone, gasi risingasiyi mushure, saka inonaka kupfuura mvura ine chlorinated. Asi mvura yemubhodhoro inopfuura mvura yemupombi maererano nekuchena uye kuchengeteka? Kashoma. Mvura yemubhodhoro haisati ichisangana nehutano hwepamusoro kupfuura mvura yepombi. Tsvagiridzo inoratidza kuti mhando dzemvura zhinji dzemumabhodhoro dzine makemikari mamwe chete uye zvigadzirwa semvura yemupombi, senge trihalomethanes, nitrate, uye maion esimbi anokuvadza. Inenge chikamu chimwe muzvina chemvura yese yemubhodhoro inotengeswa inongogadziriswa mvura yemupombi inowanwa kubva kumvura yeruzhinji. Mabhodhoro epurasitiki, mune mvura, anowedzera kuumbwa kwayo neboka rose remakomponi anokuvadza kune hutano. Vanhu vanoshandisa mafirita vanofanira kuyeuka kuti mafirita anoda kuchengetedzwa kwakakodzera uye anofanira kutsiviwa nguva nenguva. Sezvo mvura yakachena ichikosha kumuviri, kunaka kwemvura inopedzwa kunofanira kuva chinhu chinokosha pakurarama kwakanaka. Tinofanira kuita zvose zvatinogona kudzivirira matsime emvura yokunwa pakusvibiswa.
