Mark Chin

Project Geologist

Professional Profile

Mr. Chin has 14 years of experience in developing and implementing work

plans for CERCLA remedial investigations and petroleum spill

investigations. He has extensive experience interpreting chemical,

geological, and hydrogeological data, organizing field activities, and

authoring reports. He is a highly capable field manager, and has directed

site remediation programs involving hundreds of monitoring locations and

extensive trucking of contaminated soils.

Experience

Jet Blue Terminal 5, JFK International Airport, Geologist / Field Manager -

This project entailed a subsurface investigation program and removal of

contaminated soils at Jet Blue Terminal 5, JFK International Airport. As

Project Geologist, Mr. Chin supervised the contractor in the drilling of

over 100 wells to delineate existing petroleum plumes. He generated the

boring logs, collected the soil data, and was responsible for tabulation

and analysis. Contaminated soil at this site was excavated and trucked to

an approved landfill. Mr. Chin served as Field Manager for this effort,

coordinating and tracking the locations of approximately 40 trucks, each

making two runs per day. He collected the truck manifests to ensure that

each truck carried the proper tonnage and verified these tonnages by

contacting the landfill each day.

Soil Remediation for Westside Avenue Lot, North Bergen, NJ,

Geologist/Environmental Field Supervisor - In anticipation of the

construction of a new 2.43 acre bus parking lot, soil remediation was

required due to existing petroleum contamination at the site. For this

soil remediation project NJDEP regulations required significant record

keeping and due diligence in performance of the work. Mr .Chin supervised

all of the waste handling and disposal on the project which included

screening 95,000 cubic yards of ID-27 contaminated soil to separate and

offsite dispose of 18,000 tons of construction debris and 66,000 tons of

the contaminated screened ID-27 soil. The remaining soil was segregated as

reusable as part of the backfill prior to future use.

Town of Oyster Bay Liberty Industrial Finishing Site, Farmingdale, NY -

Environmental Field Supervisor provided continuous dust monitoring during

excavation activities at a 7.5 acre portion of the former Liberty

Industrial Finishing Superfund site located in Farmingdale, New York. The

excavation work was conducted under contract with the Town of Oyster Bay

which is under direction of a USEPA directive to clean up remaining

contaminated soils not already remediated by the principal responsible

parties environmental consultant. Tasks included screening soils with

photoionization detector (PID), observing any anomalies including buried

tanks, evidence of contamination and footing removal of buildings already

demolished. Areas of concern were sampled for chromium and cadmium, test

pitted for deeper delineation and surveyed to determine areas for further

excavation.

Buried tanks were encountered, spills reported and follow up coordination

with the NYSDEC was provided detailing sampling plans, nature of contents,

notifications of removal, and tank closure report submittal. Tank content

characterization sampling and surrounding bottom and sidewall soil samples

were collected to delineate extent of contamination.

Soil and waste removal manifest tracking was also performed to monitor the

contractor's performance and soil characterization sampling was performed

before stockpiles were removed. Daily progress of slab excavation and

surface restoration was monitored with records maintained. Daily safety

meetings were conducted in the mornings with the contractors to review

precautions with working around excavation equipment and waste hauling on a

busy site and provide dust control measures on windy days with water

trucks.

NYCDDC BEGS Requirements Contract for Environmental Services: Environmental

Scientist/ Project Geologist for the "on-call" work-order based contract to

perform Phase I/Phase II Environmental Site Assessments (ESAs) and corridor

studies in support of NYCDDC property acquisition and corridor

rehabilitation projects. More than 100 task orders have been issued and

completed. Mr. Chin has performed all aspects of Phase II site

investigation field work, including drilling supervision, borehole logging,

monitoring well installation, subsurface soil sampling, and groundwater

sampling.

Owl Hollow Soccer Field, Geologist / Field Manager - The New York City

Department of Parks is converting this former landfill into a soccer field.

Mr. Chin undertook a subsurface investigation program to locate areas of

trapped methane and determine the location of the cap layer of the

landfill. Using his knowledge of local sediments rock formations, he

directed the contractor in the excavation of test pits and the installation

of monitoring wells, and he collected and logged soil samples. From these

he tabulated the key analytical data, creating legible tables in MS Excel.

As Field Manager, he worked closely with the contractor and relayed

findings the project office.

Melrose Common, NYC Department of Housing, Preservation, and Development,

Geologist - New York City is attempting to redevelop this large plot of

land in the Bronx, which includes former gas stations, laundromats, and

areas of previous leakage. Mr. Chin performed a Phase I environmental site

assessment, followed by a Phase II site investigation. Soil vapor

monitoring was used as a cost-effective method of sampling the soil without

the need for extensive excavation or drilling. Mr. Chin directed the

contractor in the installation and retrieval of more than 100 soil vapor

probes. Each required the contractor to break the existing pavement or

sidewalk, drill down 5 feet, and install the probe. Key areas were followed

by a more extensive drilling process. As Mr. Chin helped the contractor

through the learning curve, the process became very efficient. Once the

process was complete, Mr. Chin collected data from the probes, tabulated

it, and made recommendations for remediation.

Water Line Disinfection, NYC School Construction Authority, Division of

Industrial Hygiene, Geologist - Mr. Chin is responsible for overseeing the

disinfection of water lines at various New York City public schools. The

plumbing in these schools, including new or replaced water lines, was

cleared of potential contamination. Each line was purified by injecting it

with chlorine, flushing it out, then sampling water from the line to ensure

that there was no residual chlorine or bacteria. Mr. Chin served as the

"eyes and ears" of NYSCA's IH Department, observing the contractor's work,

reviewing the laboratory reports, and watching for discrepancies. In each

case, Mr. Chin provided recommendations to NYCSCA as to how to proceed with

the program and what corrective measures needed to be implemented. To date,

four schools have had waterlines disinfected: Art Leather High School, PS

244Q, Urban School for Law (Family Court High School), and Murry Bergtraum

High School.
