Assessment and Remediation

Assessment and Remediation

Trihydro’s experience managing environmental assessment and remediation projects dates back to 1984 and includes work on some of the nation’s most complex remediation sites. We guide clients through the entire environmental remediation lifecycle from initial strategy development and design to system implementation and site closure. Our expertise addresses potential concerns across various media, including soil, groundwater, surface water, sediment, and air/vapor at diverse sites with legacy environmental issues. Trihydro’s team of experienced engineers, geologists, and scientists uses our knowledge of federal and state-specific regulations to design and implement practical environmental remediation solutions.

Legacy Site Management

Legacy Site Management

With over 40 years of experience, Trihydro is a trusted partner in managing legacy industrial, refinery, and mine sites, guiding our clients through every phase of the remediation lifecycle to return these properties to productive use. Historically, industrial facilities were often idled during economic downturns in anticipation of future production. Some never reopened and were dismantled with inconsistent attention to site restoration, material recycling, or salvage. Environmental conditions were often overlooked during shutdowns, prompting the development of modern regulations to guide proper closure and remediation. Today, there is growing interest in repurposing remediated brownfield sites rather than developing untouched greenfields. By leveraging best practices and key services refined over decades, Trihydro helps clients reduce environmental liabilities and confidently transform legacy sites into compliant, functional assets.

Mine Reclamation

Mine Reclamation

Trihydro helps our clients navigate the mine reclamation process to transform mine-impacted lands back into healthy, productive ecosystems. In the past decade, we’ve helped clients achieve final permit closure for multiple mine sites. Backed by 40 years of environmental and engineering expertise, Trihydro’s in-house technical specialists create stable land surfaces, establish vegetation, and monitor water quality so sites meet their intended future use. Trihydro uses advanced technology to enhance design accuracy, construction tracking, and performance monitoring, providing high-resolution data that supports informed decision-making and efficient site evaluation. Our tools include UAS (drone) data collection, LiDAR-based surface modeling, GIS and spatial analysis, and 3D visualization and volume tracking.

Mine Water Management

Mine Water Management

Effective mine water management is essential throughout the mine lifecycle—from initial permitting through operations to closure, reclamation, and legacy impacts. Addressing the interconnected challenges of water quantity and quality, engineered systems, compliance, and water rights demands interdisciplinary expertise. Trihydro provides comprehensive services across the key disciplines essential for sustainable mine water management.

Environmental Permitting and Compliance

Permitting and Compliance

With decades of expertise, Trihydro helps clients secure environmental permits across federal, state, and local frameworks while supporting environmental compliance. Our team understands the permitting processes under key laws such as the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the National Environmental Policy Act, enabling us to anticipate challenges, streamline applications, and effectively engage with regulatory agencies. Beyond environmental permitting, Trihydro develops and implements tailored environmental compliance management programs to meet environmental regulatory obligations. This includes monitoring, reporting, auditing, and training supported by our multidisciplinary team of scientists, engineers, and regulatory experts. Whether addressing air emissions, water discharges, waste protocols, or site remediation, our proactive, integrated approach helps clients minimize risk, maintain operational continuity, and align with environmental goals.
