kutayidwa mosasamala ku Beale AFB. Madzi amayenda kumwera chakumadzulo.
Ndi Pat Elder, January 2, 2020
Makilogalamu masauzande a Per- flu fluoroalkyl zinthu, (PFAS) aipitsa madzi apansi panthaka, Bear Air Force Base, yomwe ili pafupi ndi Beale Air Force Base, yomwe ili pamtunda wa makilomita 50 kumpoto kwa Sacramento. Ma carcinogen amphamvu ochulukirapo, omwe amadziwika kuti "mankhwala osatha" amapezeka pozimitsa moto womwe Gulu Lankhondo lakhala likugwiritsa ntchito pophunzitsa zozimitsa moto kwazaka 40. Gulu Lankhondo ladziwa zovuta zoyipa zomwe PFAS ili nayo paumoyo wa anthu kwakanthawi, koma ikupitilizabe kugwiritsa ntchito zinthuzo.
Beale yadzazitsa mitsinje ndi ngalande zam'madzi zapansi panthaka zomwe zimayambitsa khansa. Madzi apansi panthaka a Beale amapezeka kuti ali ndi magawo 200,000 pa trilioni ya PFOS & PFOA, mitundu iwiri yakufa kwambiri ya PFAS.
Akatswiri azaumoyo ku Harvard ati 1 ppt ya PFAS m'madzi akumwa ndi yowopsa. Mankhwalawa amayambitsa khansa ya impso, chiwindi, ndi testicular, ndipo zimathandizira kuti munthu akhale ndi khansa ya m'mawere. PFAS imayambitsanso zovuta za fetus, tinthu tating'onoting'ono tomwe timabadwa kumene, ndipo zimathandizira ku matenda ambiri aubwana, kuyambira ADHD mpaka Autism mpaka mphumu yaubwana.
US EPA yapereka upangiri wa zaumoyo, kutanthauza kuti anthu akuyenera kudziwa zoyipa ngati mankhwalawo afika magawo 70 pa trillion (ppt) m'madzi akumwa kapena pansi pa nthaka, ngakhale silikulamula makampani amadzi kuti aletse kuperekera madzi owonongeka kwa makasitomala .
A California State Water Management Board Board amalimbikitsa kuti dongosolo lamadzi litsekedwe ngati PFOA ndi PFOS zidakwanitsa kupitilira 70 ppt.
Ngati madzi azidutsa 5.1 ppt ya PFOA kapena 6.5 ppt ya kachitidwe ka madzi a PFOS California iyenera kudziwitsa maboma am'deralo kuti malirewo adutsa. Izi ndi zochulukirapo, zofanana ndi madontho ochepa mu dziwe lakuya Olimpiki. State State Board amalimbikitsa omwe opereka madzi amadziwitsa makasitomala ndi California Divice la Kumwa Madzi (DDW). Akuluakulu am'madzi boma ati magawo atsopanowa "apangidwa kuti ateteze ku khansa ndi zotsatira zake za khansa, kuphatikiza chiwindi ndi chitetezo cha mthupi."
Mu 2019 DDW idayesa zitsime za 568 kudera lonselo, ngakhale kuyesa nthawi zambiri sikunayikidwe magulu ankhondo. Zitsime 308 (54.2%) zidapezeka kuti zimakhala ndi mankhwala osiyanasiyana a PFAS. DDW sinayese madzi a Beale a PFAS ku 2019. Sanayesenso City of Wheatland, District District Water Y North, Linda County Water District, Cal-water Service Company - Marysville, kapena Olivehurst Public UD.
Amayi oyembekezera sayenera kumwa madzi okhala ndi PFAS.
Omwe amapereka madzi m'matauni amatha kusefa zonyalazo pogwiritsa ntchito zosefera zamtengo wapatali zomwe zimayenera kusinthidwa nthawi zonse. Kodi akuchita izi kuti amwe madzi anu? Itanani DDW 916 449-5577 kuti muyambe kudziwa ngati madzi anu ali ndi ma carcinogen ochokera ku Beale AFB.
Muyenera kudziwa kuchuluka kwa PFAS m'madzi omwe mukumwa.
Matendawa amabweretsa chiwopsezo chachikulu kwa anthu ogwira ntchito ku Beale, okhala m'makomo okhala, komanso omwe amamwa zitsime zochokera pansi. Zinyama, mbalame, ma invertebrates, zolengedwa, nyama zapamadzi, ndi nsomba zomwe zimakhala kapena kusamukira ku Beale AFB zimakhudzidwa ndi othandizira amphamvuyi oyambitsa khansa.
