Phantse iinyanga ezisixhenxe ezidlulileyo-Matshi 3, 2020 -ukuchaneka, abahlali abangamakhulu amathathu abachaphazelekayo baxinana kwilayibrari yaseLexington Park ukuva uMkhosi wamaNavy ukhusela ukusetyenziswa kwawo ngezinto ze-per-and-poly fluoroalkyl (PFAS) kwiSikhululo soMoya sePatuxent River ( Pax River) kunye neWebster Outlying Field.
Abantu babekhathazekile kuba ndandisandula ukupapasha iziphumo zovavanyo ibonisa amanqanaba esayensi yeenkwenkwezi zetyhefu eSt Inigoes Creek, ezantsi apha eSt.Mary's County, nje i-2,400 iinyawo ukusuka eWebster Field apho izinto zazisetyenziswa rhoqo iminyaka emininzi.
Ngokukhawuleza ndabelana ngeziphumo zam neSebe lezeNdalo eMaryland, kwaye ndafumana le mpendulo kwisithethi. “ISebe lezokusiNgqongileyo eMaryland okwangoku alinazo iingcebiso malunga nezinto ezingcolisayo kwiimbatyisi. Ekuphela kwemingcele eyaziwayo ye-PFAS inxulunyaniswa namanzi okusela, apho umngcipheko wokuvezwa mkhulu. ”
Impendulo evela kwi-MDE ibonisa ukungasebenzi kukarhulumente kwaye ichaza ngokungachanekanga ukuba ukubonakaliswa kwi-PFAS yeyona nto inkulu emanzini okusela. Uninzi lwePFAS kwimizimba yethu kukusebenzisa ukutya kwaselwandle okuvela emanzini angcolisekileyo. Zombini i-Navy kunye ne-MDE bakuqonda kakuhle oku. Kukulungele ukuba urhulumente afune oku ngenxa yokuba izinto zokusela zikamasipala zinokunyangwa. Ukulungisa ukungcola komkhosi kwimikhosi yamanzi e-ethe-ethe lelinye ibali. Ezi "ziikhemikhali ezingunaphakade" kwaye zihlala ixesha elide, into efana nesiqingatha sobomi bezinto ezinemitha yeathom.
Kungekudala emva kwentlanganiso elayibrari, eyabonakala iyintlekele yemicimbi yoluntu kuMkhosi wamanzi kunye ne-MDE, urhulumente uqalise isifundo somqhubi ukuvavanya inqanaba lokungcoliseka kwePFAS emanzini angaphezulu kunye neembatyisi kufutshane nePax River kunye neWebster Field. I-MDE ibhengeze ukuba iziphumo ziya kuba zilungile phakathi ku-Meyi.
Ziphi iziphumo, eMaryland?
Nge-fluoro octane sulfonic acid (PFOS) yafunyanwa elunxwemeni lwam kwiindawo ezili-1,544 ngeetriliyoni. (ppt.) I-PFOS lolona hlobo lubulalayo kuyo yonke imichiza ye-PFAS kwaye i-bio eqokelelene ngokungaqhelekanga, oko kuthetha ukuba iyakha-kwaye ayisoze yaphuka koononkala, iimbatyisi, kunye nentlanzi edla rhoqo eMarylanders.
Ngokusekwe kwiziphumo zam nakwiziphumo ezivela kumakhulu eentlanzi kunye namanqanaba e-PFOS ahambelana neendlela zamanzi kwilizwe liphela, iMaryland ngokuqinisekileyo ineembatyisi ezinamawaka eenxalenye ngeetriliyoni zePFOS ngelixa amagosa ezempilo oluntu aphezulu esixwayisa ukuba singadli ngaphezulu kwe-1 ppt ngemini yezi tyhefu zidityaniswe nomhlaza kunye nokungaqheleki kosana olungekazalwa.
Emuva ngo-Matshi, u-Ira May, owongamele ukucocwa kwendawo ye-MDE, ubuze ukuba ngaba akukho kungcoliseka na eSt. Inigoes Creek ngokusekelwe kwiziphumo endizifumeneyo. Ukuba iikhemikhali bezikhona, ucebise ukuba zinokuvela kwisebe lomlilo lendawo. Izikhululo zomlilo e-Valley Lee naseRidge zimalunga neekhilomitha ezintlanu kude. Indoda ephezulu yelizwe igubungela ezomkhosi.
Ngelixa silinde iziphumo. I-MDE ikhuphe le ngxelo ilandelayo ngokubhekisele kungcoliseko lwePFAS:
“Abaxumi kufuneka bazi ukuba umngcipheko wokuba sesichengeni sokutya iintlanzi ezibanjisiweyo kunye neembaza zihlala zingaphantsi kakhulu kunentlanzi kunye neembaza. Kungenxa yokuba abathengi abathenga iintlanzi neembaza kumthengisi oqinisekisiweyo abafumani ntlanzi okanye iqokobhe kwindawo enye veki nganye okanye inyanga. ”
Lo ngumgaqo-nkqubo woluntu ocekisekayo. Beka okanye uvale, iMaryland. Ziphi iziphumo?
