At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and covers 18,400 square meters of total area alongside the river Parana and therefore has been declared as an Area pf Permanent Protection (APP) by the State. It was mandatory therefore, that the soil is remediated without excavation nor disturb the local pristine flora and fauna. The treatment of soil was made using Pump and Treat method by washing soil with rain water through erecting irrigation canals in the soil and the water contaminated with washed oil was then treated with AgroRemed. The results showed considerable reduction in TPH values in soil and in one case the value was reduced from 766,965 ppm to 72 ppm.
