I-PFAS (i-per- kunye ne-polyfluoroalkyl substance) licandelo le-aqueous film-forming foam (AFFF) esetyenziswa ekucimeni umlilo kwizikhululo zeenqwelo-moya. Ukusetyenziswa kwe-AFFF kuyimfuneko ekucimeni umlilo zeenqwelo ngenxa yobume bomlilo wenqwelomoya.
ISebe lezoThutho laseHawaii (HDOT) lithatha amanyathelo okujongana nomhlaba ochaphazelekayo we-PFAS kwindawo ekufutshane ne-Kahului Airport (OGG) i-Aircraft Rescue and Firefighting (ARFF) Training Pit. Amanyathelo athathwa yi-HDOT abandakanya ukubiyela indawo apho isampuli zomhlaba zibonisa i-PFAS kunye nokungeniswa kwesicwangciso sokulungisa okwethutyana kwiSebe lezeMpilo laseHawaii (HDOH).
Ngelixa i-AFFF ingasakhululwa kuqeqesho lokucima umlilo namhlanje, ibisetyenziswa kuqeqesho phambi kowama-2021. Izithuthi ze-ARFF kwilizwe lonke ziye zatshintshwa ukuze zinciphise ukusetyenziswa kwe-AFFF kuphela kwimililo ngamafutha eenqwelomoya okanye ezikufutshane.
Ngokusekwe kusetyenziso lwembali, iSebe lezoThutho laseHawaii laqala iisampulu zomhlaba zePFAS kwiindawo ezintandathu. Ezi ndawo zezi: 1) i-OGG ARFF Training pit, 2) i-ARFF yangaphambili yoQeqesho lwe-ARFF kwi-Airport ye-Daniel K. Inouye International, 3) i-ARFF Training pit kwi-Ellison Onizuka International Airport e-Keahole, i-4 & 5) i-ARFF yangaphambili Imingxunya yoQeqesho kwiSikhululo seeNqwelomoya saMazwe ngaMazwe saseHilo, kunye nesi-6) esasisakuba se-ARFF yoQeqesho kwiSikhululo seenqwelo-moya saseLihue. Isampulu yesayithi ye-OGG yafumanisa iikhompawundi ezininzi ze-PFAS kumanqanaba okanye ngaphezulu kweSebe lezeMpilo laseHawaii lokunxibelelana rhoqo nomhlaba kwiminyaka emininzi.
Amanzi aphantsi komhlaba aphantsi kwendawo yoqeqesho lomlilo aye achaphazeleka yiPFASs.
Amanzi aphantsi komhlaba ayingomthombo wamanzi okusela kwaye akasoyiki eminye imithombo yamanzi okusela kwesi siqithi. Uphando olongezelelweyo lokungcoliseka kwamanzi aphantsi komhlaba luyaqhubeka.
Kukho amawakawaka ePFAS akhoyo ngoku eUnited States. Ikhemikhali nganye ineempawu ezahlukeneyo kwaye inokusetyenziselwa iinjongo ezahlukeneyo okanye inokubakho nje njengemveliso ebingalindelekanga yemveliso ethile okanye ezinye iinkqubo. Ubuthi bekhemikhali buyohluka. I-HDOT iya kuqhubeka isebenza kunye ne-HDOH kwizenzo zokulungisa kule ndawo.
