40- Hour Hazardous Site Worker
8-Hour Supervisor
Confined Space Entry
Competent Persons at Excavations
8- Hour Refresher – Annual
Certified Environmental Inspector
The Princeton Course Certificate, Groundwater Pollution and Hydrology

Professional Background

Mr. Maguire has more than 25 years of experience managing environmental projects with soil and groundwater concerns. He develops and implements hydrogeological investigations and remedial plans, performs technical analysis of data and directs on-site field activities for related services. His experience includes design, installation and operation of groundwater remediation systems for unique client needs.

Project Experience

Commissioned and managed a 4 million gallon per year groundwater-treatment system project at a northern NJ manufacturing facility. Operations effectively maintained hydraulic control under a NJPDES permit and reduced the total chlorinated solvents level by an order of magnitude. Through competitive bidding and negotiations with the NJDEP, reduced the client’s annual operating costs by 40 percent.
A Phase I Environmental Assessment was conducted for a major New York Financial Institution. 10 out-of-service underground storage tanks and 26 hydraulic lifts were identified at the former automobile dealership in Irvington, NJ. A preliminary Geoprobe soil investigation was conducted to determine the scope of work and provide potential cleanup costs. Gross contamination was indicated. In order to meet the time frame specified in a purchase agreement, removal of all hydraulic lifts, USTs and contaminated soil was completed in 90 days.

A Memorandum of Agreement was signed with the NJDEP and a Remedial Action Report submitted within 30 days of completion of field activities. NJDEP approved the No Further Action (NFA) proposal for the soils, which allowed demolition of the existing buildings and permitting for new construction. A groundwater investigation was conducted that included nine monitoring wells, aquifer characterization tests and negotiations for a monitoring program in a condensed time frame. An NFA was issued for groundwater based on fate and transport calculations in a petition for Classification Exception Area. Based on the NFAs, the client was able to secure a 25-year lease with a major retail chain. Total project time from contract to case closure was 15 months.

Provided claims adjustment services within the AIG Homeowners Environmental Liability Protection program for the worlds largest environmental investigations firm.

Provided accelerated groundwater remedial investigation to a New York Developer for a project in Elizabeth NJ. Based on the on-time completion of the work, which proved an off-site contamination source, the client was able to show his lender a successful Urban renewal project in New Jersey, take advantage of favorable lending rates, and refinance $800,000 into his next project.

Wrote requests for proposals, selected subcontractors and provided onsite project team coordination for cleanout, security and disposal of complex waste streams from a closed 450,000 square foot Hospital Medical Center in a suburb of New York City which was purchased by a major hotel chain. The closed facility had been vandalized and required expedited attention for the health and safety of the community, and regulatory compliance for the disposal of medical, hazardous, and recyclable waste. 1,900 rooms were inspected, cleared and secured in 20 days for NYSDEC inspection. Thus secured, inventoried and characterized, all wastes were properly manifested off site in less than five days.

Mr. Maguire has managed projects in Florida, Connecticut, Virginia, New York State, and California.

Mr. Maguire has served as project hydrogeologist on several projects where innovative or highly customized remedial solutions were required.
