abstract

• Soil contaminated by petroleum is a pervasive problem in Mexico, particularly in the Southeast (Tabasco and Veracruz), which has provoked a serious damage of the ecosystem. A study examined the biological treatment technology to clean up petroleum-contaminated soil with emphasis in bioaugmentation and nutrimental conditions. The soil used was an acidic soil containing 220,000 mg/kg TPH and a native population of 2 × 105 CFU/g. CO2 production was higher in those microcosms bioagumented. Removal of aromatic and asphaltenic fractions was enhanced at an extent of 11%25 with respect to those microcosms not bioagumented during the first 38 days of treatment. Bacteria had its growth exponential phase during the first 30 days, which correlated with both fractional removal. C/P ratio increased during the first 7 days of treatment. This is an abstract of a paper presented at the 19th Annual Conference on Soils, Sediments, and Water (10/20-23/2003, Amherst, MA).
