STS offers Risk Assessment services to assist clients with
the evaluation and management of chemical contamination
at their own facilities or at facilities under consideration
for acquisition. Risk assessments can be used to determine whether
remedial action is actually warranted, and if so, to focus remediation
efforts (or administrative and institutional controls) onto only
those chemicals, environmental media, and site-specific areas
that are likely responsible for the majority of the potential
risks. STS also uses risk assessments to determine the concentrations
of contaminants that can remain on-site and still be adequately
protective of public health and the environment.
Risk-based decision-making generally consists of two fundamental
components risk assessment and risk management.
Risk assessment entails the evaluation of project-specific data,
information on the hazardous properties of chemical substances,
and the extent of receptor exposure to these substances in order
to characterize the potential health risk to various human and
ecological receptor populations.
Risk assessments are applicable to all major Federal and State
environmental programs and public health-based laws. Risk assessment
has emerged during the past 15 years as a useful tool to assist
in property transfers, due diligence compliance, liability audits,
and the determination of rational cleanup levels for contaminated
sites.
Risk management integrates the risk assessment results with
other information (such as applicable legal requirements, economics,
engineering feasibility, and community/public concerns) to arrive
at decisions about the need and approach for risk reduction.
