ENVIRONMENTAL RISK ASSESSMENT

Environmental risk assessment is a means of evaluating possible harm to human health or ecological surroundings as a result of exposure to certain chemicals. It has been incorporated as a decision making tool into nearly all major federal and state regulatory programs. Risk based methods are used in programs ranging from establishing wastewater discharge limits and drinking water goals to underground storage tank (UST) closures to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) projects.

Results oriented risk assessments focus on differentiating between actual versus perceived problems for human health and the environment and clearly communicate the realistic issues. Use of risk assessment in the decision-making process can result in more effective resource efficient remediation or treatment, reduced toxic tort liabilities, and improved public relations.

Kennedy/Jenks has a unique team of engineers and scientists that provide integrated support for risk assessment and engineering projects. Our risk assessment team works closely with our clients to develop responsive, effective, yet practical solutions to environmental problems.

Risk Assessment Projects

	Sediment Investigation and Ecological Risk Assessment for Former Wood Treating Facility A former wood treating facility located on Scappoose Bay in St. Helens, Oregon discharged primarily polycyclic aromatic hydrocarbons (PAHs) to site groundwater, soils, sediment, and surface water. MORE...
	Vapor Intrusion for Human Health Risk Assessment Kennedy/Jenks developed a risk-based tiered approach to assess the potential risks that included sampling of groundwater, soil gas, and crawlspace or indoor air, as needed, when screening levels were exceeded. MORE...
	Alkali Lake Ecological Risk Assessment Alkali Lake had been historically used as an herbicide waste disposal site. Primary contaminants in soil and groundwater at the site were bioaccumulative compounds, including dioxins, furans, phenols, and chlorinated herbicides and pesticides. MORE...
	Portland Harbor Superfund Site When sediments in Portland Harbor were found to contain contaminants, the potentially responsible parties, regulatory agencies, and local community needed to understand the potential risks to people who fish, swim, and work in the area as well as to migratory birds, fish, and other wildlife species. MORE...
	Hazardous Waste Collection The County of Ventura wanted to develop a permanent collection facility for household hazardous wastes to address a rising demand from a growing population. The County had identified two possible sites for the facility, but was concerned about potential risks to human health and the environment. MORE...
