Environmental Risk Assessments

Creekside has successfully managed and completed projects involving Human Health and Ecological Risk Assessments for Northwest clients. The objective of the Human Health Risk Assessment (HHRA) is to present an evaluation of potential risk (constituents, media, and exposure routes) to human receptors at a site and adjacent areas that may be associated with existing and possible future use conditions. The goal is to assess whether current conditions at the subject property are considered protective of human health considering the current and potential future use of the site, and applicable surrounding area.

The Ecological Risk Assessment (ERA) is performed for the purpose of screening for contaminants of potential ecological concern and calculating site-specific risks associated with ecological exposure. The primary objective is to assess whether conditions at the subject site are considered protective of current and potential future land and water uses. The ERA is based on current and historical information, along with soil, sediment, groundwater and surface water data that are collected during the course of site specific field work. In conjunction with the scope of work involved with Risk Assessments, Creekside can also develop health advisories or other health recommendations, and identify actions necessary to prevent future negative human health or environmental effects.
