Expert Witness and Litigation Support
To provide senior level technical litigation services and regulatory expertise.
SLR professionals provided senior technical litigation assistance services to a client in preparation for an arbitration hearing concerning the scope of work and financial responsibility to remediate subsurface contamination at a gas station site in Seattle, Washington. The work consisted of reviewing the opposing party's recommended scope of work and evaluating if the scope was appropriate for the site and contaminant conditions. The opposing party was proposing to remediate the soil and groundwater to MTCA Method A cleanup levels, which would cost more than $9,000,000. SLR identified weaknesses in the opposing party's approach; calculated site-specific, risk-based Method B cleanup levels for the impacted soil; and justified groundwater cleanup levels based on protection of surface water. SLR then developed two remediation alternatives to meet the recommended cleanup levels. The estimated remediation costs to meet the recommended cleanup levels ranged from approximately $1,400,000 to $3,500,000.
