Kleinfelder leverages the principles of risk analysis and risk management to bring value to various client projects.  Specifically, our risk analysis and toxicology solutions focus on human health risk assessment (HHRA) applied to hazardous waste release sites—a critical tool for determining whether mitigation measures or remedial action are required to restore a site for particular land uses. We also apply our expertise to assess infrastructure risk, including pipeline failures, railroad derailments, and structural collapses.
