PFAS (per- and polyfluoroalkyl substance) ndi gawo la thovu lamadzimadzi lopanga mafilimu (AFFF) lomwe limagwiritsidwa ntchito pozimitsa moto pama eyapoti. Kugwiritsa ntchito AFFF ndikofunikira pakuzimitsa moto pa ndege chifukwa cha chikhalidwe cha moto wamoto wa ndege.
Dipatimenti ya Hawaii Department of Transportation (HDOT) ikuchitapo kanthu kuthana ndi nthaka yomwe yakhudzidwa ndi PFAS pafupi ndi Kahului Airport (OGG) Aircraft Rescue and Firefighting (ARFF) Training Pit. Masitepe omwe HDOT ikuchita ndikumanga mpanda pamalo pomwe zitsanzo za nthaka zikuwonetsa PFAS ndikupereka ndondomeko yokonzanso kwakanthawi ku dipatimenti ya zaumoyo ku Hawaii (HDOH).
Ngakhale kuti AFFF siinamasulidwenso pamaphunziro ozimitsa moto lero, idagwiritsidwa ntchito pophunzitsa isanafike 2021. Magalimoto a ARFF m'dziko lonse lapansi adasinthidwanso kuti achepetse kugwiritsa ntchito AFFF kokha kumoto ndi mafuta a ndege kapena pafupi.
Kutengera momwe amagwiritsidwira ntchito m'mbiri, dipatimenti ya Zamayendedwe ku Hawaii idayamba kuyesa nthaka ya PFAS m'malo asanu ndi limodzi. Malo awa ndi: 1) OGG ARFF Training Pit, 2) yomwe kale inali ARFF Training Pit ku Daniel K. Inouye International Airport, 3) ARFF Training Pit ku Ellison Onizuka International Airport ku Keahole, 4 & 5) wakale ARFF Maphunziro a Pits pa Hilo International Airport, ndi 6) omwe kale anali a ARFF Training Pit pa Lihue Airport. Sampuli ya tsamba la OGG idapeza mankhwala angapo a PFAS omwe ali pamwamba kapena pamwamba pa dipatimenti ya Zaumoyo ku Hawaii kuti agwirizane ndi nthaka pafupipafupi kwa zaka zambiri.
Madzi apansi pa malo ophunzitsira moto akhudzidwanso ndi PFASs.
Madzi apansi panthaka si magwero a madzi akumwa ndipo saopseza madzi ena akumwa pachilumbachi. Kufufuza kowonjezereka kwa kuipitsidwa kwa madzi pansi pa nthaka kukupitirira.
Pali masauzande a PFAS omwe alipo pano ku United States. Chilichonse mwa mankhwalawa chimakhala ndi zinthu zosiyanasiyana ndipo chingagwiritsidwe ntchito pazolinga zosiyanasiyana kapena kungokhalapo ngati zinthu zosayembekezereka za kupanga kapena njira zina. Kawopsedwe wa mankhwalawa amasiyanasiyana. HDOT ipitiliza kugwira ntchito ndi HDOH pakukonzanso patsamba lino.
Zambiri pa PFASs zilipo health.hawaii.gov/heer/environmental-health/highlighted-projects/per-and-polyflouroalkl-sbstances-pfass or epa.gov/pfas.
ZOMWE MUNGACHITE PA NKHANIYI:
- Dipatimenti ya Hawaii Department of Transportation (HDOT) ikuchitapo kanthu kuthana ndi nthaka yomwe yakhudzidwa ndi PFAS pafupi ndi Kahului Airport (OGG) Aircraft Rescue and Firefighting (ARFF) Training Pit.
- Masitepe omwe HDOT ikuchita ndikumanga mpanda pamalo pomwe zitsanzo za nthaka zikuwonetsa PFAS ndikupereka ndondomeko yokonzanso kwakanthawi ku dipatimenti ya zaumoyo ku Hawaii (HDOH).
- Kugwiritsa ntchito AFFF ndikofunikira pakuzimitsa moto pama eyapoti chifukwa chamtundu wamoto wamafuta a ndege.
