Past industrial and resource extraction and management practices often led to contaminated or unstable sites that now pose potential risks to human health and the environment. Herrera’s team of biologists, chemists, geologists, and engineers take a holistic approach to restoring “damaged” sites to healthy ecosystems or productive commercial uses. We provide the full range of remediation services—from site assessments through construction oversight. Our experts assess contamination potential through Phase I and Phase II property assessments; develop and evaluate alternative strategies for remediation; produce plans, specifications, and cost estimates for projects to stabilize and reclaim abandoned mine sites; design and implement large-scale revegetation (on sites of 100 acres or more); and monitor the progress of remediation efforts. We see each project as an opportunity to make our world better.
