A REVIEW OF INVESTIGATION AND REMEDIATION REGULATIONS AND PROCESSES
This report covers an investigation and remediation review of contaminated sites. Mainly speaking, petroleum hydrocarbon contaminated sites. First, it makes a gathering of international legislative framework and structure of contaminated soil control, using the Netherlands, Germany, the USA and Brazil as references. It discusses some topics on investigation methodologies: (i) geological and hydrogeological assessment; (ii) pollutant and source information review; (iii) definition and implementation of an “in situ” investigation· plan; (iv) selection of
health and environmental criteria and comparison with measured concentrations; (v) corrective action plan. The article discusses alternatives of site remediation, which include groundwater remediation techniques (“in situ” treatment, isolation, extraction and surface treatment) and soil remediation techniques (“in situ” treatment, excavation and surface treatment). Finally, it points out some trends of sites remediation in Brazil and abroad.

After the accident that happened in Guadalajara, Mexico, when fuel leaked into the sewerage system and caused a great explosion, the concern about leakage and soil contamination with petroleum hydrocarbons remarkably increased. Considered a recent subject in environmental control, the investigation and remediation of petroleum hydrocarbon contaminated soils in gasoline stations has had great
advancement in Brazil, concerning both the development of control methodologies by environmental agencies and studies carried out by private organizations. An evidence to this fact is that São Paulo has housed two technical meetings on safety in gasoline stations. In practice, however, soil investigation and remediation techniques and methodologies are not yet widely spread.
Considering the subject of extreme importance, this paper will present a review on the regulations and criteria adopted in the Netherlands, Germany, the USA and Brazil. Also discussed is a methodology to address the problem.
