Risk Assessment & Special Studies

Our team of innovative and applied scientists have extensive experience in water and sediment effect ratios, TMDLs, BMPs, and the development of other site-specific criteria including soil, remediation, and other environmental special studies.

The interface between science and policy is key to applying regulatory guidelines in making appropriate site‐specific decisions. Our staff has an impressive history of effective interface between dischargers and regulatory agencies, including modifying existing regulations, developing site‐specific criteria (e.g. Water and Sediment‐Effect Ratios), and assisting with environmental risk assessment to aid in the planning and decision‐making processes. In many cases, support for site‐specific applications of regulations involves the integration of toxicity, chemistry, and bioassessment information in order to provide a complete picture that fully justifies the proposed alternative. Thus, a science‐based approach is generally the most effective in terms of developing and maintaining credibility with the regulators, as well as providing a fundamentally sound basis for discussion.
