PRACTICE AREA

Complex Environmental and Natural Resources Litigation and Administrative Practice 

Where law, science, and
real-world impact intersect.

Our firm handles complex environmental litigation and administrative proceedings for clients facing technically demanding and consequential disputes—matters where scientific complexity, regulatory overlap, and significant financial exposure converge. Whether representing companies, property owners, public entities, individuals, or insureds, we bring deep substantive knowledge and disciplined strategy to dispute.


OUR EXPERIENCE

Focus on the issues that matter most.

Claims involving alleged exposure to hazardous substances, contaminants, chemical releases, including causation and intensive individual and mass claims.

Toxic Tort & Exposure Litigation


Superfund liability, cost allocation, contribution disputes, remediation-related claims among potentially responsible parties, property contamination disputes, and claims involving soil and groundwater contamination.

Cost Recovery Litigation


Claims under comprehensive environmental liability and pollution policies, covering the cost of defense and indemnity benefits for environmental remediation.

Insurance


Proceedings before the New Mexico Environment Department and the Oil Conservation Division, analyzing appropriate cleanup methodologies, and limiting exposure in agency enforcement actions.

Administrative Law

Technical depth.
Practical solutions.

For the past 40 years, we have built this practice to operate at the intersection of law and science. Environmental cases are based on technical detail—contamination pathways, exposure science, regulatory history, and competing expert opinions—and our attorneys work directly with toxicologists, hydrogeologists, engineers, and other specialists to master that detail. Command of the science, combined with close collaboration with our clients on strategy and objectives, allows us to present and litigate these matters with clarity and conviction.

Command of the science changes the case.

Environmental litigation rarely turns on legal argument alone. Our ability to translate complex scientific and regulatory records into compelling, understandable arguments gives our clients a decisive advantage - whether in settlement negotiations or at trial.
