SOIL AND GROUNDWATER CHARACTERIZATION AND REMEDIATION

Aquifer Testing and Characterization
This project was completed to assist in the characterization of the soul-source aquifer at a municipal well field located in north-central, Arizona. Some of these tests were conducted to better characterize the aquifer impacted with volatile organic compounds (VOC). The scope of work involved step and aquifer testing on various test and production wells, including analysis of resulting data. The aquifer study included single and multiple well aquifer tests and the management of an on-site groundwater treatment system for the removal of VOC impacted waters.

Drilling and monitoring well construction in Arizona

 


Diesel Spill Characterization and Excavation
This project involved sampling, and coordination of a large scale excavation project. The scope of work included oversight of waterway dredging in compliance with a United States Army Corps of Engineers (USACE) 404 permit. Due to the job site being in an area that included National Audubon Sealed private properties, it required thousands of soil and water samples, geographic records, documentation, and analysis.

 


Soil Farming Bioremediation Field Testing

This project involved the management, monitoring, and oversight of a bioremediation soil farming field testing facility. The work was conducted at a secure military base and involved directing the excavation and handling of TNT impacted soils. Impacted soils were composted with nutrients and other materials to be tilled and treated using soil farming bioremediation.

 


Impacted Soil and Groundwater Tier II Modeling Assessment
This work involved the derivation of Illinois Environmental Protection Agency (IEPA) Tier II groundwater point of compliance and soil saturation assessment modeling. This work was conducted to assist in confirming the on-site management of volatile organic compound (VOC) impacted groundwater.

 


Groundwater Recovery Pump and Treat Assessment
This project involved the hydraulic assessment and eventual design of a groundwater recovery pump and treat system for the remediation and control of groundwater impacted by petroleum based cutting fluids.

Site characterization work in Michigan

 


Creosote Impacted Soil Dredge Project
This work involved the coordination and confirmation monitoring of a large scale waterway remediation dredging project in northern Mississippi. The work involved management and coordination of all on‑site activities including the excavation of bank and bottom deposits of creosote impacted soils, the design and placement of cut‑off dams, soil, water, and product sampling, subcontractor coordination, and monitoring of all on‑site waste storage and final landfill disposal.



Federal Superfund Site Operations and Management
This project involved groundwater monitoring and sampling tasks under the direction and oversight of the United States Environmental Protection Agency (USEPA) at a Federal Superfund Site in southwest Michigan. This work entailed continual monitoring of the on‑site remediation systems as well as long term groundwater monitoring.

 


Groundwater Modeling and Remediation Corrective Action Review
This project involved the technical review of a pump and treat groundwater remediation corrective action report. The report detailed the effectiveness of a pump and treat system that was suggested for groundwater impacted by volatile organic compound (VOCs), and a three-dimensional groundwater model to help characterize the chosen remediation technologies. This work was conducted as an internal quality assurance review prior to final submission to the USEPA at a Federal Superfund site in southern Arizona.

 


VOC Plume Characterization and Monitoring
This scope of work involved groundwater sampling at over 80 well locations throughout the Phoenix metropolitan area for characterization and monitoring of a volatile organic compound plume. This work involved extensive coordination with numerous landowners and development of sampling protocols for various groundwater well construction details. In addition, long‑term groundwater monitoring hardware were deployed and protocols developed for various geologic scenarios.

 


Plume Identification and Characterization Oversight
This work was conducted to identify possible migration pathways and non‑compliance concerns regarding impacts at various sensitive receptors. This site work included various testing and sampling for the Michigan Department of Environmental Quality (MDEQ) to assist in plume characterization and identification, and involved surface water sampling for dioxins and furans as well as soil‑vapor extraction pilot testing, sampling, and reporting.

Site characterization work in Arizona

 


Plume Characterization Investigation
This program was completed at an Michigan Department of Environmental Quality (MDEQ) State cleanup site to characterize groundwater quality and its migration from an abandoned landfill. This involved the characterization of deep (>400 feet) groundwater flow systems using site-specific drilling and sampling field program. The work included various sampling techniques including vertical aquifer sampling (VAS) using vibra‑sonic drilling techniques, as well as deep groundwater sampling and well construction below numerous basal till geologic formations.

 


Gasoline Contaminated Groundwater Plume Migration Modeling
This work was conducted to assess the contaminant migration for site characterization and inclusion with the Corrective Action Plan (CAP). The project required aquifer testing and evaluation of a gasoline contaminated groundwater plume to estimate migration at a fueling yard in Phoenix, Arizona.

 


Oversight and Management of Field Activities at State of Arizona Water Quality Assurance Revolving Fund Sites ‑ Phoenix, Arizona:
These projects involved numerous phases of work as detailed below:Performed on‑site management and oversight duties for the Arizona Department of Environmental Quality (ADEQ) at Arizona Water Quality Assurance Revolving Fund (WQARF/"State Superfund") sites in Phoenix, Arizona. The work involved development of a database and geographical representation of the current site conditions for use in public presentations;Long term management and monitoring at multiple ADEQ WQARF Project Sites; andWorked on data acquisition, database development, and management at numerous ADEQWQARFState remedial project sites throughout central Arizona. Responsible for communication and coordination with clients and landowners. In some cases these projects involved the coordination of data from multiple WQARF sites and hydraulic monitoring at a variety of environmental settings.

 


Groundwater, Surface Water, Sediment, and Soil Sampling Experience
Many projects have involved groundwater, surface water, sediment, and soil sampling activities for a wide variety of analytes ranging from perchlorate to bacteriological profiles to dioxins and furans. This work has employed a variety of United States Environmental Protection Agency (USEPA) and state approved protocols.

 


Numerous Underground Storage Tank Investigations and Excavations
These projects involved subsurface sampling to determine soil and groundwater impacts related to leaking underground storage tanks. This work included drilling and open trench excavations for tank removal. This work also involved correspondence and reporting with regulatory agencies to achieve proper tank closure.
