Isishayamthetho sase-Ohio State saphasisa umthethosivivinywa wokwenqabela ukuchithwa kwamanzi okuvulekile kwenhlabathi eboshiwe ngemva kukaJulayi 2020 futhi sancoma ukuthi kutholwe okunye ukusetshenziswa okunenzuzo kwenhlabathi eboshiwe.
Njengoba ukulahlwa kwamanzi avulekile akuseyona inketho futhi izindawo zokulahla ezivalekile sezisondele umthamo ogcwele, imibono emisha iyadingeka ukuze kutholakale izindlela zokusebenzisa kabusha okunenzuzo nangokongayo endaweni.
I-US Army Corps of Engineers, Ohio EPA, kanye nezinye Izifundazwe, kanye nohulumeni Bendawo bebesebenza eduze ukuze bakhe izinhlelo, okuhlanganisa ukusetshenziswa okunenzuzo kwezinsalela, ukuze kuhlangatshezwane nezidingo zomthetho omusha.
Isixazululo esisodwa esingaba khona ukuthola izindlela ezongayo zokukhipha inhlabathi egugulekile ukuze kwakhiwe inhlabathi edayiswayo noma izichibiyelo zenhlabathi.
Emzamweni wokusebenzisa ngokunenzuzo inzika eboshiwe, iDolobha lase-Lorain lathola i-Ohio Healthy Lake Erie Grant eqondiswa uMnyango Wezemvelo wase-Ohio kanye ne-Ohio Environmental Protection Agency ukuze kwakhiwe Indawo Yokuphinda Kusetshenziswe Inzuzo I-Black River Dredged Material.
Lesi sikhungo sisendaweni yedolobha e-Black River Reclamation Site eduze nendawo yezimboni e-brownfield e-Black River.
Lobu buchwepheshe obusha bokukhipha amanzi emanzini obubizwa ngokuthi i-GeoPool buqukethe amafreyimu ahambisanayo ahlanganiswe ne-geofabric axhumene ukuze akhe umumo oyisiyingi oqinile ozungezayo kanye nangaphansi komhlaba.
I-slurry yentlenga eboshiwe bese iphonswa echibini lapho amanzi ehlunga khona ngamafreyimu anemigqa ye-geofabric kuyilapho isigaba esiqinile sigcinwa ngaphakathi kwechibi.Idizayini iyi-modular, iyasebenziseka kabusha, futhi iyakaleka futhi ngaleyo ndlela ingafakwa ezidingweni zephrojekthi.
Ocwaningweni lokuhlola, i-GeoPool engu-~1/2 acre yaklanywa ukuthi ibambe i-cubic yards engu-5,000 yenhlabathi eboshiwe.Ngo-Agasti 2020, i-sediment hydraulically dredged from a federal turning basin (Lorain Harbour Federal Navigation Project) e-Black River yaphonswa ku-GeoPool futhi yachithwa ngempumelelo.
Ukuze ufunde kabanzi mayelana nokuthi i-sediments ekhishwe ngamanzi ingasetshenziswa kanjani ngokunenzuzo, ukuhlolwa kokusalela okuqinile kuyaqhubeka okwamanje.Ukuhlolwa kwezinto eziqinile eziphelelwe amanzi kuzosiza ekunqumeni ukuthi kudingeka izinyathelo ezengeziwe zokwelashwa ngaphambi kokuba umhlabathi usetshenziswe.
Okuqinile kungase kusetshenziselwe izinjongo eziningi ezihlukene ezihlanganisa, isibonelo, ukubuyiselwa kwesiza esiseduze se-brownfield, ukuxuba nezinye izilinganiso zokwakha, ezolimo, kanye nokulima.
