Remedial Investigation

ECI has provided remedial investigation and feasibility study services throughout the world for private clients and government entities. ECI provided a New York State facility with bio-cell design, construction, operations & maintenance, and final disposition of the contaminated soils. The contaminated soils were discovered during an excavation project and the New York State Department of Environmental Conservation (NYSDEC) was notified and opened a spill investigation/number. ECI recognized the soils as fill from a foundry/steel production operation and site UST that may have leaked. The soils were highly contaminated with oil/solvents. ECI worked closely with the client and the NYSDEC to obtain on-site bio-cell design approval. ECI then provided the remediation project turnkey; supplying construction of the bio-cell and operations and maintenance of the bio-cell including sampling/analysis until the remediation effort was completed and the “spill” removed from the agency’s books. ECI provided all documentation for this “spill” remediation effort.

ECI completed a Chromium Encapsulation Project in the People’s Republic of China- Project No. 2002-30084A for the U.S. Trade and Development Agency.  ECI reviewed the technical, economical, financial, regulatory, and political aspects of applying a United States based chromium encapsulation technology/reagent to over 20 sites throughout China.  The chromium encapsulation reagent was proposed to neutralize large (i.e., 250,000 cubic meters in size) “mountains” of chromium contaminated by-product waste.  The treated by-product waste would prevent rainwater run-off and both surface and ground water chromium contamination.  ECI received praise and the highest marks on the Evaluation of Advisory and Assistance Procurement form filed by the U.S. Trade and Development Agency for the work performed on this project.  In addition, the U.S. Trade and Development Agency wrote: “The report took a very difficult subject and provided a clear recommendation to TDA based on the information provided.

ECI has worked on the in-situ remediation of a New York State Department of Environmental Conservation (NYSDEC) spill investigation/number for a fleet trucking and truck maintenance garage. ECI provided turnkey services to treat the soils and groundwater in-situ and provide spill investigation/number documentation for the NYSDEC. ECI injected biological bacteria and nutrients into the monitoring well for a 2-year period and have provided sampling/analysis and written documentation to the NYSDEC during this time period.

ECI worked closely with the client and NYSDEC on a site turnkey project where 30 bore holes/monitoring well were drilled and tested indicating contamination. Subsequently a NYSDEC spill number was assigned to the site. ECI designed the removal and remediation effort providing negotiations with the NYSDEC. ECI excavated and removed a gasoline UST and contaminated soils/water during the project. ECI provided sampling/analysis and excavation of contaminated soils and groundwater and their transportation and disposal in addition to the excavation/removal and disposal of the UST. The NYSDEC required the development of a Soil & Groundwater Management Plan that ECI authored and submitted to the NYSDEC on behalf of the client. The project concluded with a letter from the NYSDEC stating that the client required “No further action”.

ECI personnel assisted in managing for the NYSDEC the remedial design of a landfill for the solvent contaminated Sweden-3 Chapman Properties site.  ECI personnel developed the remediation work plan, which included use of a groundwater interceptor trench, groundwater pump-and-treat system, low-temperature thermal desorption (LTTD) soil treatment system, and landfill cap. At NYSDEC’s request, ECI personnel managed the technical evaluation concerning the feasibility of applying metal-enhanced reductive dehalogenation (MERD) also known as Zero-Valance permeable reactive barrier technology as an alternative to the interceptor trench and pump-and-treat system.  Upon NYSDEC’s approval of the remedial design, ECI personnel managed the preparation of engineering plans and specifications for the LTTD system and auxiliary equipment and identified pretreatment, site development, and building and process operations required.

ECI reviewed a complex New York State Superfund site located in Cheektowaga, New York for use of Zero-Valance permeable reactive barrier technology. The existing pump and treat system was not reducing the chlorinated solvents concentration due to the presence of dense non-aqueous phase liquids (DNAPL) in the limestone bedrock only 3-4 feet below ground level. ECI provide engineering design, costing, and construction schedules for the proposed project. In addition, ECI provided expert knowledge and discussions with the lead attorney regarding expected impacts from the use of the permeable reactive barrier technology on the site and reduction of the mobility of the plume including off-site migration issues.

ECI personnel evaluated the Idaho National Engineering and Environmental Laboratory’s (INEEL’s) remedial efforts for Operable Unit 7‑08 (Organic Contamination in the Vadose Zone [OCVZ]) at the Radioactive Waste Management Complex, in order to identify design and operation and maintenance (O&M) issues regarding the vapor vacuum extraction and treatment (VVET) system that could affect DOE compliance with the site Record of Decision (ROD). ECI personnel initial comments concerning an evaluation of the preferred alternative specified in the ROD led DOE to use a regenerative thermal destruction unit rather than the catalytic oxidation unit specified in the ROD.  In subsequent comments, potential situations where identified such as hydrogen chloride emissions would exceed permissible levels; DOE/EPA addressed these factors in the final implementation strategy.  In addition, ECI personnel reviewed the remediation contractor’s preliminary design and specifications for the VVET system, identifying numerous potential problems, including seasonal operational difficulties that would have prevented year-round unit operation (subsequent installation/operation of the units verified these findings).  ECI personnel also completed a regulatory compliance review concerning the applicability of 40 CFR 264 Subpart AA that was incorporated into the DOE implementation strategy.  Comments on the OCVZ remedial design/remedial action work plan addressed over 110 deficiencies, including design and operating parameters.

ECI personnel also evaluated the applicability of in-situ vitrification for INEEL’s buried waste program and addressed associated technical and programmatic deficiencies.  The evaluation covered existing and revised process instrumentation and control drawings, DOE safety analysis reports, existing permits and applications, and other engineering/operating documents. Potentially serious equipment flaws related to the capture and treatment of off-gas emissions and associated worker protection were identified; under simulated conditions, a pilot-scale test verified these findings.
