Tetra Tech EC’s first Navy contract at Hunters Point Naval Shipyard was awarded in 2002. They provided cleanup of about 20 percent of the land surface at Hunters Point Naval Shipyard and were among many contractors providing remedial services at the site. Tetra Tech EC put safety at the forefront of its projects and worked more than 2,000 days (or 5.4 years) without a lost time injury at Hunters Point Naval Shipyard.
In 2012 the Navy identified soil sampling data at one location at Hunters Point Naval Shipyard that did not appear representative of the sampling area. Tetra Tech EC immediately conducted a full investigation. At its own expense, they analyzed 70,000 sample results, identified areas for resampling, and conducted additional remediation where necessary. After implementing corrective actions, there were no repeat occurrences.
Tetra Tech EC fully documented the investigation and completed corrective actions with full review by and coordination with the Navy and regulators. The Navy also conducted an independent review and released its own report in 2014. The report concluded that “The Navy’s contractor corrected identified deficient conditions and incorporated additional QC steps to avoid recurrence.”
