I-PFAS (into ngayinye kanye ne-polyfluoroalkyl) iyingxenye yamagwebu e-aqueous film-forming (AFFF) asetshenziselwa ukulwa nomlilo ezikhumulweni zezindiza. Ukusetshenziswa kwe-AFFF kuyadingeka ekucimeni umlilo ku izikhumulo zezindiza ngenxa yemvelo yokubasa umlilo wendiza.
Umnyango Wezokuthutha wase-Hawaii (HDOT) uthatha izinyathelo zokubhekana nenhlabathi ethintekile ye-PFAS eduze ne-Kahului Airport (OGG) Aircraft Rescue and Firefighting (ARFF) Training Pit. Izinyathelo ezithathwa yi-HDOT zifaka phakathi ukubiyela indawo lapho amasampula enhlabathi ekhombisa i-PFAS kanye nokuhanjiswa kohlelo lokulungisa lwesikhashana kuMnyango Wezempilo wase-Hawaii (HDOH).
Nakuba i-AFFF ingasakhululwa namuhla ekuqeqesheni ukulwa nomlilo, ibisetshenziswa ekuqeqesheni ngaphambi kuka-2021. Izimoto ze-ARFF ezweni lonke zishintshiwe ukuze kukhawulwe ukusetshenziswa kwe-AFFF kuphela ngemililo esebenzisa uphethiloli wendiza noma eduze.
Ngokusekelwe ekusetshenzisweni komlando, uMnyango Wezokuthutha waseHawaii waqala ukuthatha amasampula enhlabathi ye-PFAS ezindaweni eziyisithupha. Lezi zindawo yilezi: 1) Umgodi Wokuqeqesha we-OGG ARFF, 2) Umgodi Wokuqeqesha we-ARFF wangaphambili e-Daniel K. Inouye International Airport, 3) Umgodi Wokuqeqesha we-ARFF esikhumulweni sezindiza samazwe ngamazwe sase-Ellison Onizuka e-Keahole, 4 & 5) i-ARFF yangaphambili Imigodi Yokuqeqesha Esikhumulweni Sezindiza Samazwe Ngamazwe Sase-Hilo, kanye 6) Nomgodi Wokuqeqesha we-ARFF wangaphambili esikhumulweni sezindiza i-Lihue. Isampula yesayithi ye-OGG ithole amakhompiyutha amaningana e-PFAS kumazinga wesenzo sezemvelo woMnyango Wezempilo waseHawaii ukuze uxhumane njalo nomhlabathi eminyakeni eminingi.
Amanzi angaphansi komhlaba ngaphansi kwendawo yokuqeqesha umlilo nawo athintwe amaPFAS.
Amanzi angaphansi komhlaba awawona umthombo wamanzi okuphuza futhi awasongeli ezinye izinsiza zamanzi okuphuza esiqhingini. Uphenyo olwengeziwe lokungcoliswa kwamanzi angaphansi komhlaba luyaqhubeka.
Kunezinkulungwane ze-PFAS ezikhona njengamanje e-United States. Ngayinye yalawa khemikhali inezakhiwo ezihlukile futhi ingase isetshenziselwe izinjongo ezihlukene noma ingase ibe khona njengemikhiqizo engahlosiwe yokukhiqiza okuthile noma ezinye izinqubo. Ubuthi bamakhemikhali buyahlukahluka. I-HDOT izoqhubeka nokusebenza ne-HDOH ezenzweni zokulungisa kuleli sayithi.
Ulwazi olwengeziwe ngamaPFASs luyatholakala ku health.hawaii.gov/heer/environmental-health/highlighted-projects/per-and-polyflouroalkl-sbstances-pfass or epa.gov/pfas.
