Project Related Work in Other States

  • Provided litigation support for a commercial industrial facility in New York, including determination of onsite and offsite sources of contamination. Detailed evaluation of soil and groundwater contamination patterns and fate and transport of contaminants lead to successful outcome of litigation.
     
  • Performed an environmental site assessment of a nursing home in North Carolina. Supervised the removal of an underground storage tank, which provided fuel to the emergency generator at the site. Also designed and supervised the installation of and prepared a Spill Prevention, Control and Countermeasure Plan for an aboveground storage tank providing fuel for the generator.
     
  • Prepared Stormwater Pollution Prevention Plans and Spill Prevention, Control and Countermeasure Plans at ten (10) asphalt plants in North Carolina. Prepared and implemented the plans, conducted required sampling, and conducted training of site personnel to perform the necessary sampling.
     
  • Conducted Phase I Environmental Site Assessments at more than fifty (50) undeveloped and developed residential and commercial properties in North Carolina. The commercial properties included office buildings, gas stations, auto repair facilities, a lumber yard, several stores, numerous residences, and several small manufacturing facilities. Phase II activities included sampling for asbestos, lead-based paint, and soil and groundwater contamination. Succeeded in obtaining site closure at the areas of contamination which allowed for commercial and residential redevelopment of the area.
     
  • Conducted a Phase I and Phase II Assessment of a former manufacturing facility in North Carolina. Supervised the removal of buried drums. Worked with the client and the State of North Carolina and succeeded in obtaining entry of the site into the State Brownfields program. The site was developed into a manufacturing facility.
     
  • Conducted a Phase II assessment at a major hospital in North Carolina. Designed and supervised the installation of a large underground storage tank which provided fuel for the emergency generator at the hospital and also provided emergency heat for the facility. Supervised the removal of two (2) large underground storage tanks at the hospital, assessed soil and groundwater contamination from a previous fuel oil spill, and developed a recovery plan for fuel oil leaking into the basement from the spill.
     
  • Conducted a Phase I Environmental Site Assessment of a North Carolina site prior to an acquisition. Phase II investigative activities included confirmatory asbestos sampling and soil sampling to delineate contamination associated with surface stains and underground storage tanks. Supervised the removal of eight (8) underground storage tanks, including the closure in place of three (3) large tanks that could not be removed due to their proximity to the site building. Assessed soil and groundwater at the site and obtained site closure which allowed the facility to be sold.
     
  • Conducted Phase II assessment and remediation activities at a large North Carolina public park. These activities included the assessment and removal of underground storage tanks and obtaining site closure at several locations. Designed and supervised the installation of a gasoline underground storage tank. Also designed a system to remove free product on groundwater at one (1) location in the park.
     
  • Supervised the collection of geologic data at a potential low level radioactive waste disposal site. This included review of soil and core descriptions and large-scale surface trench descriptions. Prepared the data for review by the State of North Carolina.
     
  • Conducted a Phase I Environmental Site Assessment of a large inactive rail yard in Pennsylvania, which the city proposed to convert into an industrial park. The Phase I report included recommendations, a sampling and analysis plan and a cost estimate for remediation of the site.
     
  • Developed risk-based strategy for completing remediation for a Pennsylvania industrial painting company. Demonstrated that site remediation had met state-wide health standards under Act 2. Work involved determination of non-use aquifer status, plume delineation, attainment monitoring, and groundwater modeling to determine fate and transport. Site closure was obtained from PADEP.
     
  • Conducted aquifer testing to obtain aquifer parameters and prepared Baseline Environmental Report for a site in a "Special Industrial Area" under Pennsylvania Act 2 regulations.
     
  • Designed and directed remedial investigation of soil contamination below an operating manufacturing plant. Project included coordination with plant personnel and subcontractors to assure no disruption of plant activities. Following delineation of the contamination, several in-situ technologies were evaluated. Biological augmentation was selected as the remedy. Successful implementation of advanced remedial technology was accomplished while the plant continued full operation.
     
  • Conducted Phase II Environmental Site Assessment for a manufacturing facility in South Carolina. Project involved accelerated field investigation with installation and sampling of permanent and temporary monitoring wells, soil sampling, and aquifer testing. Site had multiple areas of concern, including former underground tank farm that had been previously closed by the state, which subsequently exhibited free product nearby in later investigations. Results of investigation and fate and transport analysis showed only minor impacts, and the closed UST case was not reopened.
     
  • Conducted groundwater investigation of former manufacturing facility in Florida. Work included the development of a conceptual site model and presentation to the Florida Department of Environmental Protection, and groundwater sampling to provide information required to assess future remedial options. Previous consultant had conducted extensive, disjointed groundwater investigation that showed impact beneath neighboring properties to the east and west, with potential to impact a drinking water well on an adjacent property. Encountered free oil and soil impact under the building onsite. Conducted an Interim Remedial Measure to collect free product (hydraulic oil). Discovery of undocumented subsurface structures and conditions prevented completion of the original design. Devised alternative remedial action, obtained approval from FDEP, and carried out installation of passive collection sumps. Subsequently conducted pumping tests on selected sumps to determine potential remedial alternatives. Work completed without disrupting current occupant’s operations. Prepared hydrogeologic report showing that extremely low hydraulic conductivity prevented recovery of product, but existing distribution of product with low conductivity would produce little migration.
     
  • Supervised the installation of emergency test excavations, and determined source and migration pathways of visibly impacted water observed during a rain event at an operating manufacturing plant in Mississippi. Installed a recovery sump to control impacted water. Subsequently conducted soil sampling to delineate extent of potentially impacted soil. All impacted water had been recovered and properly disposed of, and soil results showed no need for additional remediation.
     
  • Performed groundwater modeling for a California chemical facility to determine design parameters for a sheet piling funnel and gate groundwater treatment system to capture a plume of toluene and styrene contamination. Model covered two (2) adjacent properties, and included the operation of an existing dewatering sump in one (1) of the site buildings. Model also explored design parameters needed to capture an isolated plume of chlorinated solvent contamination.
     
  • Conducted site investigation/remediation activities at a paper and laminated coatings manufacturing facility in Massachusetts, which was in operation since the late-1880s. The site had poor track record with the MADEP. Releases of No. 6 fuel oil associated with the plant boiler system, and releases of alcohols and toluene from USTs associated with a former solvent recovery system were primarily addressed. A brook runs through the middle of the site; groundwater and surface runoff discharges into the brook. Remediation was complicated due to the silt and clay site geology. Remediation work involved excavation of soil impacted by toluene and alcohol in close proximity to buildings. Soil remediated in ex-situ soil vapor extraction cells. Fuel oil contamination was addressed through hot-spot excavating and risk assessment. Project was completed on schedule, and all contamination above risk-based criteria in these portions of the site was successfully removed and treated to acceptable reuse standards. Responsible for all aspects of project, including permit procurement, workplan development, field work and regulatory/client interface. Improved relations with regulatory entity and avoided monetary penalties.
     
  • Conducted soil excavation of chlorinated organics contamination adjacent to a former manufacturing facility (currently a community center) in Tennessee. Work involved soil excavation next to a building, including material that was hazardous by characteristics, using bucket augers and backfilling borings with concrete to produce retaining wall; then employed conventional excavation techniques, which were backfilled with flowable fill and clean excavated soil via a soil reuse program. Onsite analytical laboratory utilized for soil analysis to determine extent of excavation and reusable soil. Completed project successfully within schedule without impact to building occupant’s activities. Proved to TDEC that monitoring well network previously installed by another consultant was inadequate. Approved Groundwater Remedial Investigation Workplan in place for Site.
