Risk Assessment & Applied Toxicology
Commercial manufacturers, specialty chemical firms, and industry and legal-sector clients often face a complicated mix of constituents at their sites. They need to understand the implications of cumulative exposures across multiple pathways, often for multiple populations. In addition, they may be facing uncertainties associated with emerging constituents, which are often not yet well understood.
Practice Specifics
Clients turn to Geosyntec’s professional and board-certified toxicologists, risk assessors, and public health experts for human health and ecological risk assessments that can help them craft best-value, health-protective solutions for their sites. To do this, we partner with clients to support nuanced understandings of constituent-specific physicochemical properties, fate and transport mechanisms, toxicity profiles, and other important phenomena such as bioaccumulation, all while accounting for changes and updates to target compliance levels and regulations.
Geosyntec’s toxicologists help assess uncertainty and resolve data gaps. When standards created by administrative authorities do not exist, we can develop provisional toxicity criteria; this work helps our clients understand extant and future potential risk and liability and supports health-protective decisions, minimizing unwelcome surprises and averting drastic reactions to changing environmental landscapes in the future.
Admittedly, quantitative risk assessments can be complicated and can depend on a host of technical details. Geosyntec works with our clients to create sophisticated analyses, but we also ensure our clients understand the implications of key scientific management decision points to empower critical decisions about who can be where, for how long, what they can do while there.
By helping our clients understand challenges, prioritize needs, and make informed decisions, we guide their decisions to protect worker and public health and comply with applicable regulations, minimizing liability and exposure, financial or otherwise.
With specialized applied toxicology services, Geosyntec addresses exposure to common and emerging contaminants, in a variety of circumstances:
