Ecosystems Strategies, Inc. (ESI) conducts a broad range of environmental investigations to provide the Client with an accurate and comprehensive definition of on-site environmental conditions. ESI personnel utilize a combination of the technical skills, regulatory knowledge, and experience to characterize the extent of soil, water and/or air contamination. Investigative services range from simple, non-instrusive screenings Transaction Screen Assessments (TSAs), Phase I Environmental Site Assessments
(Phase I ESAs), to more focused Phase II Environmental Site Assessments
(Phase II ESAs) and narrowly defined investigations (e.g., Tank Closure Site Assessment
s (TCSAs) through to more complex Remedial Investigations / Feasibility Studies). All investigations strictly adhere to requirements set forth by the American Society for Testing and Materials
(ASTM), as well as by federal and state agency procedures and/or directives.
Brownfields / Superfund Sites
ESI conducts technical investigations and provides remedial system design and review, as well as expert testimony for responsible parties at both Federal and State Superfund properties. ESI staff has been successful in providing regulatory agencies with accurate and comprehensive data to both characterize a site and design/implement effective solutions. All investigations are conducted in strict conformance with applicable regulatory agency guidelines.
Examples of recent ESI projects are detailed below:
- Site Investigation / Remedial Alternatives Report for a 12-acre proposed conversion of abandoned underdeveloped land to a waterfront park in Irvington, New York. The site was the first Brownfields project funded by New York State under the 1996 Brownfields Initiative Project (currently renamed the Environmental Restoration Program). This office completed the Site Investigation and the Remedial Design phases of the project involving the design and construction of a geosynthetic cap, specific excavations of contaminated soils, and bulkhead reconstruction. This project was the recipient of the 2000 Engineering Showcase of Excellence Award by the 2000 American Consulting Engineers Council.
- Site Investigation / Remedial Action Plan for a former manufactured gas plant in Yonkers, New York, documenting soil and groundwater contamination. Remedial plan included site improvements to remove LNAPL and DNAPL, excavation and disposal of contaminated soil, monitoring of groundwater contamination, and the installation of a subslab vapor extraction system under the recently constructed Greyston Bakery building. The Site was completed in 2003.
- Surface and subsurface investigation to document the presence of perchloreothylene (PCE) at a USEPA Superfund site in Orange County. Conducted soil and groundwater testing, supervised soil removal activities, completed vapor intrusion studies at adjoining residences and designed groundwater remediation plan.
- Site Investigation of former boiler repair site in Poughkeepsie, New York in conjunction with New York State Department of Environmental Conservation (NYSDEC) “Brownfields” restoration project. Remedial tasks included the excavation and removal of seven (7) underground storage tanks (USTs); documentation of soil and groundwater contamination; removal of asbestos and demolition of on-site structures; removal of petroleum, metals and PCB contaminated soils; and installation of a subslab vapor system.
- Site Investigation Report / Remedial alternatives Report for the Foster Refrigeration Site in Hudson, New York (NYS Environmental Restoration Program Site). Completed soil and groundwater investigations, documenting soil contamination (Metals, PCBs) and groundwater contamination (metals). Secured NYSDEC approval of the Remedial Workplan.
- Site Investigation Report / Remedial Alternatives Report for the Perx Site in Red Hook, New York (NYS Environmental Restoration Program Site). Completed soil and groundwater investigations documenting soil contamination (petroleum contamination, pesticides). Supervised removal of contaminated soil, demolition of buildings and removal of chemical and petroleum tanks. Site has been successfully converted to senior housing.
- Site Investigation / Remedial Alternatives Report for the Long Dock Beacon Site in Beacon, New York (NYS Brownfields Cleanup Program Site). Completed soil and groundwater investigations, documenting soil contamination (petroleum, metals and PCBs) and groundwater contamination (petroleum). Secured NYSDEC approval of remedial plan; currently preparing Remedial Design drawings and specifications.
