Nws tsis yog lub cim zoo thaum txawm tias cov dev yuav tsis haus koj cov kais dej.
Frank Michna ntawm Caledonia, ib tug ntawm ntau pua tus neeg nyob rau sab qab teb sab hnub tuaj Wisconsin hais tias, "Lawv hnia nws thiab tom qab ntawd haus cov dej hauv lub raj mis uas peb nchuav," said Frank Michna ntawm Caledonia, ib ntawm ntau pua tus neeg nyob sab qab teb sab hnub tuaj Wisconsin uas nws lub qhov dej muaj cov pa phem uas tuaj yeem los ntawm cov tshauv faus.
Michna lub qhov dej yog tainted los ntawm boron thiab molybdenum. Molybdenum yog ib yam hlau uas tshwm sim los uas tuaj yeem ua rau muaj teeb meem kev noj qab haus huv xws li gout, ib qho nyuaj thiab mob ntawm kev mob caj dab, yog tias noj nyob rau theem siab. Cov tshuaj boron, kuj tshwm sim, tau pom tias ua rau digestive teeb meem thiab ua phem rau txiv neej cov kab mob.
Lub hauv paus ntawm cov no thiab lwm yam kab mob hauv lub qhov dej tuaj yeem yog cov hmoov tshauv los ntawm We Energies 'faiv fab nroj tsuag, raws li ib tug kev kawm tso tawm Lub Kaum Ib Hlis los ntawm Clean Wisconsin, ib pawg neeg tawm tswv yim ib puag ncig. Feem ntau ntawm cov tshauv tau siv los ua cov haujlwm tsim kho raws li qhov kev pab cuam hu ua "kev rov siv tau zoo," pom zoo los ntawm lub xeev thiab tsoomfwv.
Thiab nws zoo nkaus li tias Michna qhov teeb meem nyob rau sab qab teb sab hnub tuaj Wisconsin tuaj yeem koom nrog lwm tus tswv hauv lub xeev. EPA tau lees paub 157 tus neeg mob uas muaj pov thawj lossis muaj peev xwm puas tsuaj los ntawm cov hmoov tshauv thee, suav nrog 14 hauv Wisconsin, thiab hais tias ntau dua yuav raug tshawb pom raws li qhov yuav tsum tau ua hauv av tau teeb tsa.
Nyob rau hauv ib tug kev txiav txim ntev tos, US Environmental Protection Agency rau lub Kaum Ob Hlis 19 tau sau cov hmoov tshauv thee uas tsis muaj kev phom sij, nyob rau tib theem li cov thoob khib nyiab hauv tsev, thiab tsim cov txheej txheem nruj dua rau kev pov tseg thiab kev saib xyuas cov tshauv.
Ann Coakley, tus thawj coj ntawm kev tswj cov khib nyiab thiab cov khoom siv rau lub xeev Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv, tau hais tias lub xeev txoj cai siv tau zoo, tau dhau xyoo 1985 thiab tau qhuas hauv tsoomfwv cov cai tshiab thee tshauv, ua rau Wisconsin ua ntej xeev xws li Tennessee thiab Kentucky uas tsis muaj zog. txoj cai.
Coakley tau hais tias "Rau peb, peb twb tswj hwm cov hmoov tshauv ua cov khoom pov tseg," Coakley tau hais. "Qhov no yuav tsis yog qhov hloov pauv loj rau peb."
Tsoom fwv teb chaws txoj cai tau tshwm sim loj heev los ntawm qhov tsis ua tiav ntawm cov av loj loj hauv av, tshwj xeeb tshaj yog nyob rau yav qab teb xeev. Tab sis txoj cai muaj feem cuam tshuam rau Wisconsin vim qhov ntim ntawm cov tshauv uas siv rau hauv kev tsim kho. Cov kev siv no tseem yuav raug tso cai raws li txoj cai tshiab, Coakley tau hais tias, txawm hais tias tej zaum yuav muaj qee qhov kev txwv ntxiv ntawm qhov hnyav thiab lwm yam kev siv hauv tsev thiab kev tsim kho.
Txawm li cas los xij Wisconsin lub qhov dej tsis huv ua rau muaj kev pheej hmoo tias cov tshauv tuaj yeem nyob deb ntawm qhov tsis zoo.
Hauv xyoo 2011, Clean Wisconsin pom, cov nroj tsuag loj loj tau tsim ze li ntawm 1.8 lab tons ntawm cov ntoo tshauv. Feem ntau, 85 feem pua ntawm cov tshauv mus rau kev rov siv tau zoo, ua rau Wisconsin tus nqi rov qab siv dua siab tshaj hauv lub tebchaws.
Txawm hais tias muaj dab tsi tshwm sim los ntawm tsoomfwv cov cai tshiab, ntau lab tons ntawm cov hmoov tshauv tau raug muab faus rau hauv qab Wisconsin thaj av. Cov hmoov tshauv thee, cov khoom uas tshuav tom qab cov thee raug hlawv rau roj, muaj cov ntsiab lus ntawm cov khoom phom sij xws li boron, molybdenum, chromium, lead, arsenic thiab mercury.
Tyson Cook, tus thawj coj ntawm kev tshawb fawb thiab kev tshawb fawb ntawm Clean Wisconsin, tau hais tias pab pawg tau tsom mus rau nws txoj kev kawm nyob rau sab qab teb Wisconsin vim tias muaj cov ntaub ntawv. Tab sis thee tshauv yog nyob txhua qhov chaw, nws ntxiv, thiab yog li tej zaum yuav muaj kuab paug los ntawm cov tshauv ntawd.
Cook hais tias "Tsis muaj laj thawj xav tias nws txwv rau thaj chaw ntawd," Cook hais. “Nws nyuam qhuav tshwm sim rau qhov peb tab tom nrhiav. Qhov tseeb, peb paub tias cov khoom siv hluav taws xob thoob plaws hauv lub xeev tau muag lossis muab lawv cov hmoov tshauv pov tseg rau hom kev siv no. "
Coal tshauv sib txawv heev. Tej zaum nws yuav yog ya tshauv, nplua, grey, talcum-powdery particles uas nce nrog cov pa pa thiab raug ntes nyob rau hauv chimneys; hauv qab tshauv, tsaus grey cov khoom seem uas sau rau hauv qhov cub; boiler slag, cov khoom siv crystalline los ntawm cov hmoov tshauv hauv qab thiab tseem hu ua "dub zoo nkauj"; los yog sludge, ib yam khoom uas tsim nyob rau hauv lub cub tawg thaum scrubbers tshem tawm sulfur dioxide los ntawm pa.
Cov tshauv yog siv rau pob zeb, asphalt, phab ntsa thiab kev tsim kho hauv cov tsev thiab kev loj. Cov kab mob kis tau los ntawm xoob, lossis tsis tau ntim, cov hmoov tshauv tuaj yeem yooj yim nkag mus rau hauv av. Hauv nws txoj cai tshiab, EPA tau hais txog qhov muaj feem pheej hmoo ntawm kev siv cov tshauv uas tsis tau ntim rau hauv tab sis nres luv luv ntawm kev xav tau ntau txoj cai ntawm kev siv li no.
Kawm txuas cov pa phem, tshauv
Cook pab pawg pom tias, ntawm 1,000 qhov dej tau kawm nyob rau sab qab teb Wisconsin, 45 feem pua pom zoo tshaj qhov kev tswj hwm DNR ntawm 40 feem ntawm ib billion, thiab ntawm cov kwv yees li ib nrab kuj tau kuaj saum lub xeev tus qauv kev noj qab haus huv ntawm 90 ppb. Wisconsin Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv qhia tias cov dej uas muaj qib siab dua 90 ppb tsis siv rau haus lossis ua noj.
Qhov ze ntawm lub qhov dej yog qhov chaw siv cov hmoov tshauv rov qab, qhov siab dua cov molybdenum, raws li kev tshawb fawb. Tib yam muaj tseeb ntawm arsenic.
DNR tawm tsam tsab ntawv ceeb toom qhov kev tshawb pom, ceeb toom "qhov tsis txaus ntseeg" hauv cov lus teb raug cai. Coakley tau hais tias txoj kev tshawb fawb Clean Wisconsin vam khom cov ntaub ntawv tsawg dhau los ntawm thaj chaw loj dhau los ua pov thawj tseeb rau cov ntoo tshauv.
"Lub chaw haujlwm tsis pom zoo tias muaj kev sib raug zoo ntawm qhov siab molybdenum hauv cov dej hauv av nyob rau sab qab teb Wisconsin thiab kev siv cov hmoov tshauv los ntawm cov chaw siv hluav taws xob hluav taws xob hluav taws xob," said lub koom haum cov lus teb rau Cook and Clean Wisconsin.
Hauv xyoo 2013, DNR tau tshawb xyuas cov kab mob molybdenum hauv 24 qhov dej hauv cheeb tsam tab sis pom cov pov thawj txuas cov pa phem rau cov tshauv "tsis paub meej."
Lub xeev tsis taug qab txoj hmoo ntawm tshauv
Cov ntaub ntawv khaws cia rau kev rov siv tau zoo yog qhov tsis zoo, yog li nws tsis paub meej npaum li cas Wisconsin cov tshauv tau muab pov tseg rau hauv daim ntawv xoob. Lub xeev tsis xav kom cov hluav taws kub hnyiab los nthuav tawm qhov twg thiab qhov twg lawv tau txais txiaj ntsig rov qab siv ntau ntawm lawv cov tshauv thee. Ntxiv rau, cov ntaub ntawv pov tseg dab tsi muaj nyob hauv tsis ntev; Steve Kraus, tus cev lus rau Madison Gas & Electric, hais tias cov khoom siv hluav taws xob tsuas yog yuav tsum tau khaws cov ntaub ntawv rau tsib xyoos.
Daim ntawv tshaj tawm Clean Wisconsin tau hais txog kev tshawb fawb los ntawm EPA thiab lwm qhov uas qhia tau hais tias, thoob plaws tebchaws, ntau dua 26 lab tons ntawm cov hmoov tshauv tau muab pov tseg rau hauv daim ntawv tsis tau ntim hauv xyoo 2012.
Coakley tau hais tias DNR tsis khaws cov ntaub ntawv hais txog seb puas siv cov hmoov tshauv rov qab siv dua los yog xoob ntawm qhov chaw tshwj xeeb.
Ib lub tsev kawm ntawv uas muaj dej tsis zoo
Loose filling tej zaum yuav txuas nrog cov dej tsis haus dej hauv Yorkville Elementary School hauv Racine County, raws li Clean Wisconsin tsab ntawv ceeb toom.
Tus Thawj Coj Hauv Cheeb Tsam Tsev Kawm Ntawv David Alexander tau hais tias DNR tau hais kom lub tsev kawm ntawv sim nws cov dej hauv xyoo 2013. Cov kev sim no tau nce qib molybdenum - 138 feem ntawm ib billion, siab dua lub xeev cov lus qhia txog kev noj qab haus huv 90 ppb. EPA hais tias cov menyuam yaus yuav tsum tsis txhob haus dej rau ib hnub los ntawm qhov dej uas muaj ntau tshaj 80 ppb ntawm molybdenum.
Peb cov ntaub ntawv Energies tau pom tias 856 tons ntawm cov tshauv hauv qab tau siv los sau hauv tsev kawm ntawv hauv ib txoj haujlwm tsim kho, Clean Wisconsin pom.
Tam sim no, cov kwj dej hauv tsev kawm ntawv tau hla dhau los ntawm daim kab xev xiav kom cov tub ntxhais kawm siv lawv. Alexander tau hais tias nws raug nqi txog $ 8,500 ib xyoos rau hauv cheeb tsam los muab lub tsev kawm ntawv nrog cov dej ntim. Culligan cov dej txias yog muab tso rau hauv txoj hauv kev. Cov dej kais dej tsis yog siv los npaj zaub mov hauv chav ua noj.
"Nws zoo li koj yuav tsum haus litres thiab litres thiab litres ib hnub twg kom nws ua rau muaj kev txhawj xeeb txog kev noj qab haus huv ntau ntawm cov concentrations uas peb muaj nyob ntawm no, tab sis txawm li cas los xij, peb tsuas yog txiav txim siab tias nws yog qhov ua tau zoo. ” Alexander hais tias.
faus thee tshauv thoob plaws
Ua ntej cov hmoov tshauv thee tau tswj hwm hauv Wisconsin, cov khoom siv hluav taws xob raug cai pov tseg tons ntawm cov khoom nyob rau hauv ntau qhov khoob, dej, qhov chaw pov tseg thiab lwm qhov chaw.
Feem ntau ntawm Madison's Isthmus, nruab nrab ntawm Lake Mendota thiab Lake Monona, yog tsim los ntawm cov hmoov tshauv los ntawm Madison Gas & Electric Blount Street cog thiab lwm qhov chaw, xws li Oscar Mayer. Tshauv nyob hauv ntau qhov chaw ua si thiab chaw ua kis las thiab txawm nyob hauv qab lub Tsev Kho Mob St. Mary lub chaw nres tsheb uas yog ib qho pov tseg.
Txawm hais tias tsis muaj molybdenum tau pom nyob rau hauv lub nroog qhov dej, cov hlau chromium-6, kuj pom nyob rau hauv cov hmoov tshauv, tau pom nyob rau hauv qis. Cov neeg ua haujlwm siv hluav taws xob ntseeg tias cov hlau yog ib txwm tshwm sim thiab tsis yog los ntawm cov tshauv.
Scott Reigstad, tus kws tshaj lij rau Alliant Energy, hais tias kwv yees li 83 feem pua ntawm ntau dua 324,000 tons ntawm cov hmoov tshauv uas tsim los ntawm lub tuam txhab cov nroj tsuag mus rau kev rov siv tau zoo. Alliant lub chaw muag khoom, Wisconsin Power & Light Co., ua haujlwm cov nroj tsuag hauv Columbia, Sheboygan thiab Grant counties.
Feem ntau ntawm cov khoom siv rov qab siv tau mus rau hauv pob zeb thiab asphalt, uas tsis yooj yim rau hauv av. Qhov seem 21,000 tons tau mus rau mine reclamation, sau, av stabilization thiab lwm yam kev siv.
Kwv yees li 17 feem pua ntawm tag nrho cov thee tshauv uas tsim los ntawm lub tuam txhab hauv Iowa thiab Wisconsin mus rau hauv qhov chaw pov tseg lossis cov av tshauv thee uas cov tshauv khaws cia ua cov sludge lossis slurry, Reigstad tau hais.
EPA tau sau cov ntaub ntawv ua tsis tiav hauv kev khaws cov hmoov tshauv thee, suav nrog 140,000-tuj Lub Ob Hlis Ntuj cov hmoov tshauv pov rau hauv North Carolina's Dan River los ntawm cov khoom pov tseg los ntawm Duke Energies.
Nyob rau hauv nruab nrab-1990s, kev ntsuam xyuas zoo nyob ze Alliant lub kaw Nelson Dewey Ash Disposal facility qhia sulfate, boron, selenium, fluoride thiab arsenic.
Steve Jackson, Alliant tus thawj tswj hwm rau kev pabcuam ib puag ncig thiab kev npaj, hais tias lub pas dej tau ntxuav thiab kaw, thiab tsis muaj teeb meem ua pa phem tau tshaj tawm txij li thaum.
Alliant ob lub chaw ua haujlwm hauv Wisconsin, ib qho ntawm Edgewater cog ze Sheboygan thiab lwm qhov ntawm Columbia cog ze Portage, muaj cov kab thiab cov kab dej sib sau. Nws hais ntxiv, txawm li cas los xij, ib ntu qub ntawm Sheboygan lub pas dej tseem tsis muaj kab. Nws hais tias kev saib xyuas dej hauv av ze ze ntawm qhov chaw pov tseg tsis tau kuaj pom molybdenum ntawm qib siab tshaj li cov qauv kev noj qab haus huv.
Michna, uas nws qhov dej paug tsis nyob deb ntawm We Energies Oak Creek cog, tau ceev faj ntawm cov chaw khaws cov hmoov tshauv. Nws nco txog hnub xyoo 2011 thaum 25,000 tons ntawm tshauv tsoo los ntawm lub tuam txhab qhov chaw cia khoom loj ntawm ntug dej ntawm Lake Michigan. Lub tuam txhab tau puv ib tug kwj deg nrog cov tshauv thee hauv xyoo 1950, ua ntej lub xeev txoj cai tau dhau los.
DNR: Kev tshawb fawb ntxiv tau txais txiaj ntsig
Txawm hais tias DNR qhov kev thuam ntawm Clean Wisconsin tsab ntawv ceeb toom, Coakley tau hais tias lub chaw haujlwm yuav txaus siab tshwj xeeb rau kev kawm paub ntxiv txog kev sib txuas ntawm cov hmoov tshauv thee rau kev sib kis molybdenum. Qhov teeb meem, nws hais tias, tsis zoo li yuav ploj mus.
Nws hais ntxiv, txawm li cas los xij, nws tsis zoo li lub koom haum yuav ua cov kev tshawb fawb ntawm nws tus kheej vim nws cov peev nyiaj nruj. Lub DNR yog qhov txaus siab koom tes nrog lub koom haum tshawb fawb uas tuaj yeem ua tus thawj coj ntawm cov kev tshawb fawb no, Coakley ntxiv.
Tab sis Michna tau hais tias nws dhau sijhawm rau kev kawm.
Michna xav tias nws muaj kev nyab xeeb los ntawm cov kab mob tom qab nws tsoo lub qhov dej tshiab 300 ko taw hauv xyoo 2007 ntawm nws lub Nroog Racine. Tab sis ob peb xyoos tom qab ntawd, nws thiab nws tsev neeg tau pib raug mob los ntawm cov kab mob tsis meej.
Michna tau hais tias "Kuv txoj kev noj qab haus huv poob qis thiab kuv tau mob gout," “Kuv mob gout thiab kuv tsis tuaj yeem taug kev. Kuv tau txais cov insoles tshwj xeeb. "
Michna kuj tau hais tias nws tau ntsib teeb meem hauv plab hnyuv, uas nws ntseeg tias yuav txuas nrog boron hauv nws cov dej.
Boron tau tshwm sim ntawm 1,850 feem ntawm ib billion, siab dua lub xeev cov txheej txheem tswj hwm ntawm 1,000.
Molybdenum tshwm sim ntawm 27 ppb, qis dua lub xeev tus qauv ntawm 40.
Tam sim no, cov Michnas yuav tsib fwj dej ib hlis rau lawv cov dej haus. Lawv tau teeb tsa $3,000 lim dej softener.
Michna kuj tau hais tias tus nqi ntsuas ntawm nws lub tsev tshiab tau nqis los ntawm $ 385,000 mus rau $ 270,000.
"Qhov no yuav tsum yog peb lub vaj kaj siab," Michna hais.
