Ucwaningo Lukazwelonke Lokususwa Komsoco kanye Nobuchwepheshe Besibili
I-EPA ihlola izindlela ezisebenza kahle nezingabizi zokususwa kwezakhi emisebenzini yokwelapha ephethwe umphakathi (POTW). Njengengxenye yocwaningo lukazwelonke, i-ejensi yenze inhlolovo yama- POTWs phakathi kuka-2019 kuya ku-2021.
Amanye ama-database engeze izinqubo zokwelashwa ezintsha ukuze asuse imisoco, kodwa lokhu kuthuthukiswa kungase kungabizi noma kudingekile kuzo zonke izinsiza. Lolu cwaningo lusiza i-EPA ukuthi ifunde ngezinye izindlela ama-database anciphisa ngayo ukukhishwa kwezakhi zawo, kuyilapho ethuthukisa izinqubo zokusebenza nokunakekela, futhi ngaphandle kokungena ezindlekweni ezinkulu zekhephithali. Ucwaningo lunezinjongo ezintathu ezibalulekile:
Thola idatha ezweni lonke mayelana nokususwa kwezakhi.
Khuthaza ukusebenza okuthuthukisiwe kokuhwebelana ngezindleko ezincane.
Nikeza inkundla yababambe iqhaza ukuze babelane ngemikhuba emihle.
Izinzuzo kuma-database
Ucwaningo luzo:
Siza ama-database athuthukise ukukhishwa kwezakhi ngokunikeza ulwazi lokusebenza kanye nokusebenza oluvela ezinhlotsheni ezifanayo zama-database asevele azuze izindlela eziphumelelayo, ezingabizi kakhulu zokukhishwa kwezakhi.
Khonza njengesisetshenziswa sedatha esisha esikhulu ezweni lonke mayelana nokususwa kwezakhi ukuze usize ababambiqhaza bahlaziye futhi bathuthukise amanani okunciphisa izakhi angafinyeleleka.
Nikeza ngesizindalwazi esicebile sokusebenza kokususwa komsoco kuma-database, izifunda, abacwaningi bezemfundo, nezinye izinhlangano ezinentshisekelo.
Ama-database asezibonile izinzuzo zokuthuthukisa okunezindleko eziphansi. Ngo-2012, uMnyango Wekhwalithi Yezemvelo wase-Montana waqala ukuqeqesha abasebenzi base-inthanethi mayelana nokususwa kwezakhi kanye nokwenza kahle. Amakhasino abasebenzi babo abahlanganyele ngokugcwele enqubweni yokuthuthukisa anciphise kakhulu ukukhishwa kwawo kwezakhi.
Ukususwa Komsoco Kufeziwe Ezweni Lonke
Imiphumela yokuqala yohlu lwemibuzo lwe-screener isiza ekuboniseni isici esibalulekile socwaningo lukazwelonke: ukukhishwa okuthuthukisiwe kwezakhi kutholwa yizo zonke izinhlobo zama-database. Imiphumela yenhlolovo kuze kube manje ibonisa ngaphezu kuka-1,000 ama- POTWs anezinhlobo ezahlukene zokwelapha zebhayoloji (okuhlanganisa kokubili ubuchwepheshe obuvamile nobuthuthukisiwe bokwelapha) angathola isamba se-nitrogen engcolile esingu-8 mg/L kanye nengqikithi ye-phosphorus engu-1 mg/L. Isibalo esingezansi sihlanganisa lawo marekhodi anenani labantu eliphakelwa okungenani abantu abangu-750 kanye nokugeleza komthamo wokuklama okungamamalitha ayisigidi esingu-1 ngosuku.
