Premier Providers of Human Health & Ecological Risk Assessments

Our human health and ecological risk assessment specialists work with our remediation practitioners to develop site-specific solutions that achieve needed levels of protection while optimizing financial commitments and operational practicalities for our clients.

Innovative Solutions for Complex Problems

We believe that through the use of alternative, science-based approaches, risk assessment can be a powerful tool for site closure, redevelopment planning, and management of environmental liabilities.

As one example of our innovative risk assessment capabilities, we recently used a detailed spatial analysis of soil sampling results to support the averaging of composite samples in estimating exposure point concentrations for use in a risk assessment of areas adjacent to a stormwater drainage channel. Our efforts saved our client more than $500,000 in investigation costs and accelerated the implementation of remedial action at the site.

Geosyntec incorporates concepts, experience, and knowledge from multiple technical areas to better understand human health and ecological risks and provide comprehensive innovative solutions.
