Yintoni emanzini akho, Pleasanton?

NgoPat Elder, uJanuwari 23, 2020

Inqaku elilandelayo lathunyelwa kwi-East Bay Express kodwa alizange lifumane mpendulo.

Amanzi amnandi ePothingon, eCalifornia angcoliseke kakhulu yiPFAS. Ivelaphi? 

Inqaku leBrett Simpson's East Bay Express, Intlekele ezayo yoMgangatho weSizwe, (Jan. 14) khange ahlolisise ngokupheleleyo ubungakanani bungcoliseko lwePFAS kumanzi asePleasanton kwaye akaphumelelanga ukuthathela ingqalelo ukufakelwa komkhosi okufutshane njengesizathu esinokubangela ungcoliseko lwePFAS kumanzi edolophu.  

Inqaku lisithi iPleasanton's Well 8 yafunyanwa inezinto ezili-108 zetriliyoni (ppt) yePFAS. Amanzi aqulethe i-250.75 ppt ye-carcinogens, ngokutsho kweBhodi yaManzi yaseCalifornia. 

Umjikelo wokuqala wesampulu yePFAS yeeNkqubo zaManzi zikaRhulumente-Epreli 1st ukuya kuJuni 30th 2019

Imithombo: iibhodi zamanzi.ca.gov kwaye umkhosiesons.org.

Imithombo yeendaba kunye neenkqubo zamanzi kwilizwe liphela zihlala zikutyeshela ukunika ingxelo ubukho kunye nokubaluleka kwe "non-PFOS + PFOA" izinto ze-polyfluoroalkyl (PFAS) kunye nokudideka kuluntu ngumahluko phakathi kwezi kunye ne-PFOS eyaziwayo. Nge-Fluoro Octane Sulfonic Acid (PFOS) kunye nePer Fluoro Octanoic Acid (PFOA) zimbini kuneekhemikhali ze-PFAS ezingaphezulu kwe-6,000 eziye zaphuhliswa, kwaye zonke zithathwa njengezisongela impilo yabantu.  

Masizame kwakhona oko. I-PFOS kunye nePFOA zimbini iintlobo zePFAS kwaye zonke zimbi.

I-Los Angeles Times ibale ibali ngo-Okthobha ka-2019, Amakhulu amaqula angcolisekileyo eCarlifonia. Inqaku libandakanya imephu interactive uxele ukungcola kwe-PFAS kwilizwe lonke. Umzekelo, cofa kumachaphaza kwimephu yePleasanton kwaye uya kufumana kuphela amanani ahambelana nongcoliseko lwePFOS kunye nePFOA. Zizonke zi-123.75 ppt. Idolophu, nangona kunjalo, ine-127 ppt yesihlanu "enye i-PFAS" emanzini ayo, iyonke i-250.75 ppt. Cofa kwiBurbank kwaye uyakufumanisa ukuba idolophu ayinangcoliseko lwePFOS / PFOA; Nangona kunjalo, iBurbank ine-108.4 ppt yezinye iikhemikhali eziyingozi. 

I-PFBS, PFHpA, PFNA, PFHxA kunye ne-PFHxS zonke zibonise ukujoliswa kumanzi asePleasanton agqitha iphawu likhulu le-5.1. inqanaba lesaziso lePCA. I-PFHxS ibonakalise ukubethelwa kwe-77.5 ppt. Ezi khemikhali zisetyenziswa ngeendlela ezahlukeneyo kwezomkhosi nakwezamashishini. 

Ungathandabuzi ukuba ziyingozi.  

Zonke iikhemikhali ze-PFAS ziyingozi kwaye akufuneki sizisele. Amagosa aphezulu ezempilo oluntu athi i-1 ppt ye-PFAS inokuba yingozi kwimpilo yoluntu.  Owesifazane okhulelweyo ePothingon kufuneka alumkiswe kwangoko ukuba angaseli manzi ane-PFAS. 

Amanqanaba e-PFAS emanzini (amanzi okusela kunye namanzi aphantsi komhlaba) kufuneka alawulwe ngokusondeleyo kwaye axelwe rhoqo kuluntu ngurhulumente womanyano, oorhulumente, kunye noorhulumente basekhaya. Izifundo ezithunyelweyo kwiKomiti yoPhononongo lokuNgcolisa izinto eziNgcolisayo yeNgqungquthela yeStockholm inika ingxelo ngokufunyanwa kwePFHxS efumaneka kumanqanaba aphezulu emanzini ePleasanton: 

• I-PFHxS ifunyenwe kwigazi le-umbilical intambo kwaye idluliselwa kwi-umbungu ukuya kwinqanaba elikhulu kunelo libikwa kwi-PFOS.
• Izifundo zibonakalise umanyano phakathi kwamanqanaba e-serum ye-PFHxS kunye ne-serum ye-cholesterol, i-lipoproteins, i-triglycerides kunye namafutha acid asimahla.
• Iziphumo kwendlela yehomoni ye-thyroid ibonakalisiwe ye-PFHxS kwizifundo zesifo.
• Ukuvezwa kokukhulelwa kwi-PFHxS kunxulunyaniswa nokwenzeka kwezifo ezosulelayo (ezinjenge-ottis media, inyumonia, intsholongwane ye-RS kunye ne-varicella) kubomi bokuqala.

I-US ihlulekile ukwenza uQinisekiso lweStockholm elikhankanywe apha ngasentla. Ukulungiswa kwayo kuya kuchaphazela kakubi umgca osezantsi wabaninimachiza abaninzi abasebenza ngemichiza.

Kwangelo xesha, urhulumente wase-US ubonelela ngolwazi oluphantsi kakhulu kuluntu ngezi khemikhali ziyingozi. 

Njengokuba,  I-Toxnet,  Isixhobo esimangalisayo esaye savavanya ifuthe lezinto ezinjengePFHxS, sagqitywa ukubhidlizwa yi-NIH's, iLayibrari yeSizwe yezeNyango.  

I-Toxmap ibisandula ukupheliswa yi-NIH. Le nkonzo ibonelele ngemephu yokunxibelelana yokufumana iisayithi zokukhutshwa kwemichiza kwilizwe liphela. 

Impungutye ilawula i-henhouse.

Nge-EPA ihleli ecaleni kwayo ngokwala ukumisela imichiza ye-PFAS kunye ne-California ehudula iinyawo zayo ekumiseleni amanqanaba aphezulu angcolisayo ePFAS, kubalulekile kubahlali abasesichengeni njengePleasanton ukuba bakhokele ukukhusela impilo yoluntu.

Ngelishwa, oku kwahluke ngokupheleleyo kwizithethi zamagosa ezedolophu kunye namanzi kwilizwe liphela ajonge kurhulumente womanyano okanye kurhulumente wezisombululo. Umzekelo, ilungu leBhunga leSixeko sasePleasanton uJerry Pentin uthe, "Sifuna urhulumente ukuba akhokele, urhulumente wobumbano akhokele, kwaye asincede sifumane izisombululo ukuze amanzi ethu akhuseleke."

I-East Bay Express inike ingxelo, “Isixeko asikayazi indawo apho ungcoliseko luvela khona. Ngenxa yokuba imichiza iye yaxhaphaka yaza yazingisa kwindalo esingqongileyo, amanqanaba aphezulu obhaqo awasoloko esalatha kumngcolisi ocacileyo, njengeziko loshishino, indawo yokulahla inkunkuma, okanye isikhululo seenqwelomoya. ”

Kwimithombo engama-568 yovavanyo oluvavanywe ngu I-California State Resources Board Board Iikhemikhali ze-PFAS ngonyaka ka-2019, 308 (54.2%) kufunyenwe ukuba ziqulathe enye okanye eyahlukileyo ye-PFAS.

IBhodi yaManzi yavavanya isikhululo seenqwelomoya, indawo yokulahla inkunkuma eqinileyo kamasipala, kunye nemithombo yamanzi okusela kumgama we-1-mile yemithombo esele yaziwa ukuba inePFAS. Ngaphandle kwezinto ezimbalwa ezinje ngePleasanton, ukuvavanywa kuhlala kude noluntu ekufutshane kufakelo lomkhosi. Itotali Indawo ezingama-19,228 ngetoni nganye (i-ppt) ye-14 yeentlobo ze-PFAS ezivavanyiweyo zafunyanwa kula maqula angama-308. I-51% yayiyeye-PFOS okanye ye-PFOA ngelixa iipesenti ezingama-49 ezazisele zilolunye uhlobo lwePFAS        

Ngeli xesha, iziseko zomkhosi ezihlanu zikarhulumente: Isikhululo soMoya sase-China Lake Naval, iPort Hueneme Naval Base Ventura County, Mather Air Force Base, Isikhululo soMoya saseTustin i-USMC, kunye neTravis Air Force Base ziye zangcolisa amanzi omhlaba nge-11,472,000 ppt, ye-PFOS + PFOA. Ukuba malunga ne-50-50 yokwahlulahlula phakathi kwe-PFOS / PFOA kunye nezinye izinto ezingcolisayo ze-PFAS ezifumaneka kwimithombo engama-308 kuvavanyiwe kulo lonke elaseburhulumenteni nakuphi na ukubonakaliswa, oku kufakelwa ezintlanu kuya kuba luxanduva lwam lokungcola kwe-PFAS kumanqanaba angaphezu kwe-20,000,000 ppt. Ngaphezulu kweziseko zomkhosi ezingama-50 ziyaziwa ukuba zisebenzise iPFAS eCarlifonia. Umkhosi kusenokwenzeka ukuba ukhuphe amakhulu amawaka eelitha zegwebu lokulwa nomlilo eliqulathe ezi zinto zibulala i-carcinogens kumanzi aphantsi komhlaba eCalifornia.

Nangona uMkhwa uchasile ukuba amanzi amdaka angcoliswe ziikhemikhali zePFAS kwiPaki ezikufutshane neCamp, khange ichaze iziphumo zovavanyo lwamanzi aphantsi asisiseko.

Ngokufanayo, ULebrence Livermore National Laboratory awubhengezi esidlangalaleni ubungakanani bokungcoliseka kwePFAS emanzini aphantsi komhlaba okanye emanzini okusela, nangona eli ziko liphakathi kweendawo ezingcolileyo elizweni. Uninzi lovavanyo olwenziwe apho lubandakanya ukuvavanywa kwezixhobo ezinesiqhushumbisi ezinokufuna ukusetyenziswa kwezicinezeli zomlilo. Iimpawu eziguqukayo ze-organic (VOCs) ezinje nge-TCE, i-PCE, i-Uranium egqityiweyo, i-tritium, ii-PCBs kunye nee-dioxins, i-perchlorate, i-nitrate kunye ne-freon zezona zinto zingcolisayo ezifumaneka kule ndawo. 

Inkunkuma enetyhefu isasazeka kwindawo yonke, kubandakanya nemingxunya yezilwanyana ezirediyo. Izingcwabo zingcwatywa  izixhobo zaselebhu, ubumdaka bevenkile yobugcisa kunye nenkunkuma ye-biomedical. ILivermore inamachiza okulahla ityhefu kunye neziqhushumbisi eziphezulu ezitshisayo. Lo msebenzi ungcolisa umhlaba, umoya kunye namanzi kufutshane nePleasanton.

Abantu kwiPleasanton abaqinisekanga ukuba i-PFAS ivelaphi. Akunzima ukuyifumana. Vavanya amanzi aphantsi komhlaba kufutshane neLivermore kunye nePaki.
