Unyango olusemthethweni: I-California Izenzo kwi-PFAS / kwi-PFOA Kwisiselo samanzi kodwa kufuneka ezinye iimfuno zenziwe

NgoPat Elder, ngoFebhuwari 14, 2020

NgoFebruwari 6, 2020 iBhodi yoLawulo lweMithombo yaManzi yaseCalifornia yehlisa i "Inqanaba lokuphendula" kwiinxalenye ezili-10 kwitriliyoni (ppt) yePFOA kunye ne-40 ppt ye-PFOS.

Ngaphantsi komthetho omtsha waseCalifornia (iBhili yeNdibano 756), ukuba inkqubo yamanzi idlula amanqanaba okusabela kwezi carcinogens, inkqubo iyacelwa ukuba ikhuphe umthombo wamanzi okanye inike uluntu isaziso kwiintsuku ezingama-30 zokufunyanwa. Ngaphambili, inqanaba lokuphendula lalingu-70 ppt kuhlaselo lonke
Izinto ezimbini ezingcolisekileyo zidibeneyo.

Nangona urhulumente ehamba kwicala elifanelekileyo ngezi mpendulo zomthetho kunye nolawulo kwintlekele yezempilo yoluntu ebangelwe leli nqanaba lesidumbu sezinto ze-per- kunye ne-poly fluoroalkyl yezinto, (PFAS), kusekude ukuba uye kukhusela impilo yoluntu.

Abakhuseli beli nqanaba elilawula iindidi ezimbini zePFAS bathi linyathelo eliphantsi, kodwa liluncedo lokuqala ukuqala ngokujongana nesoyikiso esibangelwa zizinto ezingaphezulu kwe-6,000 PFAS. Umzekelo, amanzi ePleasanton naseBurbank aqukethe amanqanaba aphezulu anobungozi ngokulinganayo- kodwa engalawulwa iPerfluorohexane Sulfonic Acid,
(PFHxS).

Makhe sibhentsise i-etch-a-sketch yowiso-mthetho phantsi, siyisongele ngokulungileyo, kwaye siqale konke.

Akukho mntu ufanele ukuba asele amanzi ane-PFAS.

Ngenxa yokuba i-EPA yokulawula kaTrump ilele kwindawo yokutshintsha, kunyanzelekile ukuba iNdibano ikhokele ukukhusela uluntu lwaseCalifornia kunye nokusingqongileyo. Indibano isemva kwesifundo sokufunda ngalo mbandela. Iingcali kwezempilo yoluntu kunye nezazi zezendalo e-US nakwamanye amazwe zibiza i-PFAS sesinye sezothuso esikhulu kwimpilo yabantu kwimbali yoluntu.

Nanga amanyathelo afanelekileyo ukuba yinxalenye yomthetho onoxanduva:

• ICalifornia kufuneka imisele amanqanaba okuphendula anyanzelekileyo (ubuninzi benqanaba lokungcola- iiMCL's) ze1 inxenye yeetriliyoni, (ppt.) Emanzini aphantsi komhlaba kunye namanzi okusela kuzo zonke iintlobo zePFAS zidityanisiwe.
• I-California kufuneka ivalwe kwangoko ukusetyenziswa kwazo zonke iithobo zokulwa umlilo eziqukethe i-PFAS. Ukuchaphazeleka okukhulu kwePFAS ungcoliseko lwamanzi ethu okusela kubangelwa kukusetyenziswa kwezi foams ezivunyelwe ukungcolisa amanzi aphantsi komhlaba kunye namanzi angaphezulu. Izitshisi ze-foam ezinokubakho ezaziwa ngokuba zi-foor-free foams, okanye i-3F zisetyenziswa rhoqo kwizikhululo zeenqwelo moya zaseYurophu. Amalungu ePalamente yaseYurophu nabanye abaphathi bezindlu kulo lonke ilizwekazi bahlunguzelisa iintloko ngamandla emveliso yechemicals yaseMelika kwaye babhengeza ukungabi natyala kweCongress yaseMelika kunye nabezomthetho bakarhulumente malunga nalo mbandela.
• I-California kufuneka ivavanye kwangoko yonke imithombo yamanzi kuzo zonke iinkqubo zamanzi kamasipala kulo lonke ilizwe ukumisela amanqanaba eekhemikhali ze-PFAS ezininzi. Iziphumo zazo zonke iichemicals kufuneka zifumaneke kuluntu ngokulula.
• Kwangokunjalo, urhulumente kufuneka avavanye amaqula angaphantsi komhlaba abucala - ngakumbi lawo asondeleyo kwimingxunya yokutsha kweziseko zomkhosi, izikhululo zeenqwelo moya zikamasipala, kunye neendawo zoqeqesho lomlilo. Amanzi aphuma phantsi komhlaba anokuhamba ngenyawo ngosuku. Ngu-365 iinyawo ngonyaka-i-14,600 yeenyawo kwiminyaka engama-40; Kuphantse kube ziimayile ezi-3- kwaye ezinye iindawo zinokuba namanzi aphantsi komhlaba ahamba ngokukhawuleza okukhulu. Umthetho obiza urhulumente ukuba athabathe ithebhu yokuvavanya imfihlo yabucala ngaphakathi kweekhilomitha kwezi ndawo kuya kuba bubulumko- kwaye oko kufanele ukwandiswa ukuba iziphumo zibonisa ubukho bearhente ebangela umhlaza kumanzi equleni.
• Urhulumente kufuneka apapashe isilumkiso sasesidlangalaleni kwabo basela amanzi amnandi ngaphakathi kweekhilomitha ezi-3 zeziza ezichongiweyo apha ngasentla. Isilumkiso sempilo likaxakeka kufuneka sijolise ikakhulu kwabasetyhini abakhulelweyo okanye abakhulelweyo.
• Kufuneka sisekele inkqubo yokubonelela ngezibonelelo zoncedo lwamanzi kamasipala wase California. Ezi mali ziya kusetyenziswa ngokuyintloko ukuseka iinkqubo zokucoca i-Granular activated Carbon (GAC), okanye ezinye iindlela ezifanelekileyo zokucoca ii-carcinogen ukuze amanzi apompo abonelelwe phantsi kwee-MCL's ezintsha.
• I-California kufuneka ivale ngokukhawuleza ukubulawa kwe-PFAS. Umkhosi womoya uyavuma ukuba amagwebu awasebenzisayo enzelwe ukumelana namaqondo ashushu ashushu kwaye kunzima kakhulu ukuvutha. Akukho sayensi yaneleyo phaya yokucacisa ukutshisa i-PFAS.
• Urhulumente kufuneka ngoko nangoko ayalele kuvavanyo lokuhambisa amanzi amdaka elwandle ukuba afumane amanqanaba e-PFAS kwaye kufuneka aseke ii-MCL's ngezixhobo ezinjalo kwaye athintele ukungcoliseka kwezinto ukuba zingasasazeki kwimihlaba yeefama ezinokungcolisa ukutya okulungiselelwe ukuselwa ngabantu.
• I-California kufuneka ivavanye onke amanzi angaphezulu kulo lonke eli phondo ukuze ibone amanqanaba e-PFAS, kwaye urhulumente kufuneka aphuhlise i-MCL yawo wonke amanzi amdaka kunye nalawo angafakwanga lilizwe lonke.
