Summary of Project Experience
Ohio Voluntary Action Program, Certified Professional
Managed the removal of two hydraulic lifts, completed a subsurface investigation, provided an addendum to a previous Phase I property assessment, and oversaw the site-specific risk assessment under the guidelines of the Ohio Voluntary Action Program for an inactive bus maintenance facility. This investigation included the addition of eight monitoring wells to the present monitoring well network and a number of additional borings to delineate the source area for halogenated carbon impacts in the soil and groundwater.
Texas Voluntary Cleanup Program
Project Manager in charge of the environmental investigation and closure at a 15-acre former aviation services facility. Subsurface impacts of chlorinated solvents and petroleum hydrocarbons were observed in both soil and groundwater. Delineation activities included investigation of the facility and 17 off-site properties. The solvent plumes were documented to migrate to a nearby recreational lake. The monitoring well network consisted of 38 monitoring wells installed in two water-bearing zones. The investigation included assessing geological conditions and vertically delineating the DNAPL impacts. A baseline risk assessment was necessary for the project to evaluate site-specific risks and exposure pathways. The risk assessment included an evaluation of chemicals of concern for soil and groundwater at the facility, an evaluation of current and future exposed populations, evaluation of potential ecological impacts to surface water, evaluation of groundwater impacts on surface water, calculation of site-specific risks and hazard quotients for the potentially exposed populations, and summarization of the risks.
Underground Storage Tank Projects
Managed initial abatement and site assessment activities at a UST facility for a major oil company. Field activities included recovery of over 3,000 gallons of free-phase gasoline utilizing various passive and active recovery techniques. Assessment activities included installation of a monitoring well network of ten wells to delineate subsurface impacts both on and off-site and remedial pilot testing to determine applicable remedial technologies including soil vapor extraction, air sparging, and groundwater pump and treat.
Project manager in charge of designing and installing a groundwater cut-off trench to prevent migration of dissolved-phase hydrocarbons from a major oil company's facility. The cut-off trench consisted of a sparging system and monitoring points to monitor the effectiveness of the system. The project also included onsite assessment and development of a remediation system to address impacted soil and groundwater.
Project manager in charge of responding to a subsurface release of gasoline, which impacted local utilities. Work included initial abatement of free product and installation of a soil and groundwater remediation system. Assessment included installation of an on and offsite monitoring well network and design of a soil vapor survey to assess impacts to subsurface utilities. Remediation activities included installation of a soil vapor recovery system to control migration of vapors.
