EXPERTISE

GSI Conducts ecological risk assessment studies for petrochemical, manufacturing, land development, and other sites; and screens to identify sites with no ecological concerns; develops site-specific target concentrations that are protective for relevant ecological receptors. .

REPRESENTATIVE EXPERIENCE

Guidance: Served on TNRCC Workgroup to develop "Guidance for Conducting Ecological Risk Assessments at Remediation Sites in Texas" (www.tnrcc.state.tx.us/permitting/trrp.htm).

Checklists: Completed numerous TNRCC Tier 1 Exclusion Criteria Checklists to identify presence or absence of potential ecological issues at remediation sites in Texas.

Eco-Risk Assessments: Conducted ecological risk assessment and developed site-specific cleanup limits for protected ecological receptors at a gasoline pipeline release site in Texas.

Nationwide: Conducted ecological risk assessment based on U.S. EPA Region 5 framework to evaluate ecological risk associated with landfarm facility and surface water exposures at chemical plant in Ohio.

International: Evaluated ecological risk assessment for oilfield operation in Petén region of Guatemala to confirm absence of ecological effect on aquatic species.
