Toeroek provided RCRA technical, regulatory, and compliance assistance for corrective actions at the Army’s Ft. Wingate facility. We prepared and implemented a comprehensive RFI work plan, including detailed field sampling plan, quality assurance project plan (QAPP), and health and safety plan for 294 discrete and multi-incremental soil samples. A field team ranging up to six samplers was mobilized for five weeks to collect samples from excavated trenches as well as from surface soil and subsurface soils. A total of 19 sample delivery group packages reporting Level IV data were validated, including analyses of semivolatile organic compounds (SVOCs), explosives, perchlorate, and metals. The RFI report summarizing the findings was finalized with limited comments after review by USACE and other stakeholders including the tribe and NMED.
Toeroek researched remediation technologies historically used to treat dissolved-phase EDB in groundwater. We identified both representative EDB remediation technologies and sites with information concerning implementation and operation. Toeroek provided EPA with a comprehensive and detailed evaluation of EDB remediation technologies and alternatives to objectively identify reasonable expectations for success, challenges, and costs.
