High visibility Mexico projects include:

Marine Environmental Impact
Blasting Evaluation and Mitigation Study

Impact evaluation and mitigation of underwater impacts associated with underwater blasting leading to high visibility project approval located within grey whale migration route and aquaculture facilities.
– Received letter of commendation

Environmental Policy
Ecological Health Risk Study

Helped change environmental policy with respect to the acceptance of site-specific human and ecological health risk based Preliminary Remediation Goals (clean up goals) saving clients hundreds of thousands of dollars in clean-up cost.

Mexico Railway Site Remediation
Impacted Study Soil and Groundwater Quality

Used innovative technology to manage and complete of Mexico’s largest federal soil and groundwater remediation projects for the Mexican railroad in Mazatlan. Diesel fuel had been historically used to degrease locomotive engines and impacted soil / groundwater quality. Hazardous waste had been stored inappropriately at the site.

Environmental Forensic Study
Railroad Contaminant Fate and Transport


Provided third party review and environmental forensic support which eventually resulted in the exoneration of the Mexican railroads from damages associated with the explosions at Colonia Moderna, Guadalajara, Mexico that caused over $1 billion dollars worth of damages. The client had been initially identified as the sole responsible party.

Geotechnical,Marine Ecological Geophysical Study
Monitoring Underwater Construction

Provided multi disciplinary environmental, geotechnical, underwater construction monitoring, marine ecological, and marine geophysical support for the first LNG facility on the west coast of the Americas resulting in approx $1.1 million dollars worth of work.
