<prompt> Ke mekhoa efe e meraro e sebelisoang ho silafatsa mobu?nan  <response>: Instruction in English: What are three methods used to decontaminate soil? . Response in English: There are several methods used to decontaminate soil, but three common ones are:1. Bioremediation: This method uses microorganisms to break down and convert harmful substances into non-toxic materials. These microorganisms can either be naturally occurring or introduced into the soil. 2. Soil washing: This method separates the contaminants from the soil by washing it with a liquid solution. The solution can be water or an appropriate chemical, and the soil is typically washed while it is being agitated. Once the soil is washed, the contaminants separate from the soil particles and can be collected and disposed of.3. Thermal treatment: This method uses heat to remove or destroy contaminants in the soil. The heat can either be applied directly, in the form of steam or hot air, or indirectly, by heating the surrounding area. Heat causes the contaminants to evaporate or break down, allowing them to be collected or neutralized. . Response in Sesotho: Ho na le mekhoa e mengata e sebelisoang ho silafatsa mobu, empa e meraro e tloaelehileng ke: 1. Bioremediation: Mokhoa ona o sebelisa likokoana-hloko ho senya le ho fetola lintho tse kotsi hore e be lintho tse se nang chefo. Likokoana-hloko tsena li ka itlhahela ka tlhaho kapa tsa kenngoa mobung. 2. Ho hlatsoa mobu: Mokhoa ona o arola lintho tse silafatsang mobung ka ho o hlatsoa ka motsoako oa metsi. Tharollo e ka ba metsi kapa khemikhale e loketseng, me mobu o atisa ho hlatsuoa ha o ntse o ferekanngoa. Hang ha mobu o hlatsuoa, litšila li arohana le likaroloana tsa mobu me li ka bokelloa le ho lahloa. 3. Phekolo ea mocheso: Mokhoa ona o sebelisa mocheso ho tlosa kapa ho senya litšila tse mobung. Mocheso o ka sebelisoa ka ho toba, ka mokhoa oa mouoane kapa moea o chesang, kapa ka tsela e sa tobang, ka ho futhumatsa sebaka se potolohileng. Mocheso o etsa hore lintho tse silafatsang li fetohe mouoane kapa li robehe, e leng ho lumellang hore li bokelloe kapa li se ke tsa fetoha.
