UNIVERSITY OF IDAHO (UI) SWEET AVENUE
PHASE I, II, & III ENVIRONMENTAL ASSESSMENT & REMEDIATION, MOSCOW, ID


TerraGraphics was hired by the University of Idaho (UI) to conduct a hazardous waste site investigation on 11 acres of land prior to purchase. The site contained hazards from pesticide and petroleum spills. The unique project required TerraGraphics’ coordination of efforts among the Governor's office, DEQ, and the current and former property owners and tenants.

TerraGraphics' role also included determining 1) the degree, type, and extent of contamination, 2) the potential threat to human health and/or the environment, and 3) remedial actions required. An extensive investigation included collection of over 200 soil, surface water, and groundwater samples. A substantial risk assessment and a comprehensive regulatory review were performed to identify human health risks and potential liability issues.

TerraGraphics negotiated final remediation requirements with the tenants on behalf of the UI, and provided oversight and monitoring during remedial activities. TerraGraphics then oversaw interim streambank stabilization and final stream restoration efforts as the site was transformed into a beautiful greenbelt for the UI.
