Decontamination of middle to low-grade contaminated areas, using a lowcost method

CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Outra Agência Protected areas and wetlands often suffer contamination due to outcrops or by passage of contaminated fluids as rain, subsurface water or river infiltration. Due to legislation, in these areas activities which alter the natural environment are not permitted. Here we suggest and describe a methodology that can be used in all low to middlegrade contaminated areas without the necessity of structure changes, intense human interference and/or supervision.
