Risk-based remediation of a former MGP site 
in Italy
N. Lazovic, C. Rampi and P. Jarre

The paper presents the methodology and results of the risk assessment study performed in the context of a former MGP site remediation. The site is being redeveloped for a range of uses from residential, university, public open space to commercial. The impact of the soil contamination by metals,
hydrocarbons and PAHs on the public health and groundwater quality was assessed using both analytical and numerical models for contaminant fate and transport. The results of the study provided sound quantitative basis for the selection of mitigation measures and cost-effective restoration solutions.
Through the negotiation with the regulators, risk-based levels were established for soil and groundwater clean-up concentration goals, resulting in substantial savings without compromising the public safety or the environment.

Key words: contaminant fate, contaminant transport modeling, natural attenuation, risk assessment, vapor intrusion into buildings
